    Application of Hydrazine Hydrate
    Hydrates and their derivatives are widely used in many industrial applications such as chemical products, pharmaceutical products, agrochemicals, water treatment, photographic and photographic products. Hydrazine hydrate is used directly as: 1. Used as an anti-corrosion additive for circulating water in thermal power plants and nuclear power plants. 2. Oxygen scavengers in industrial boilers and high pressure steam furnaces. Hydrazine hydrate is a deoxidizer that decomposes dissolved oxygen in water and is used to further remove traces of dissolved oxygen remaining in the boiler feed water after thermal degassing. Since dissolved oxygen in the water can cause corrosion of the boiler tube wall, the addition of hydrazine hydrate in the boiler feed water can not only reduce, but also prevent the formation of iron scale and copper scale in the boiler. Hydrazine hydrate is a highly effective reducing agent that can synthesize the following products: 1. A blowing agent: azoformamide (azocarbonamide) (for example, a sodium azide product for producing an inner tube). 2. The synthesis of biologically active intermediates in agrochemical products and pharmaceutical products begins with the production of triazole. 3. Azo initiator 4. Other various products: some organic pigment products in dyes, photographic reagents, u

    Fertilizer Agglomeration Mechanism I
    Only by correctly understanding and mastering the causes of compound fertilizer agglomeration can appropriate measures be taken to prevent fertilizer agglomeration. After observing and studying the surface of the particles by electron microscopy and X-ray diffraction, crystal bridging theory and capillary adsorption theory are generally accepted. 1) Crystal bridge theory According to Crystal Bridge Theory, due to its own changes (crystal characteristics, chemical composition, particle size, particle size distribution, crystal geometry) and external conditions (humidity, temperature and pressure), moisture continuously diffuses from the inside to the surface (or Due to surface moisture absorption), the surface of the particles dissolves and recrystallizes, forming a crystal bridge at the interstices of the particles. Over time, the crystal bridges combine to form large clumps. (2) Capillary adsorption theory The theory holds that the hygroscopic fertilizer is at its critical relative humidity (also known as the hygroscopic point, referred to as crh) and uses it to indicate the hygroscopicity of the fertilizer. That is, at a certain temperature, when the fertilizer loses moisture, it begins to absorb moisture into the air or air. In relative humidity. It absorbs the water above and forms a saturated solution film of the fertilizer on the surface of the crystal. The membrane of this solution accelerates the adsorption of the capillary. The saturated vapor pressure of the capillary surface water is lower than the external saturated vapor pressure. External water vapor diffuses between the particles, absorbing moisture and deliques

    Fertilizer Agglomeration Mechanism II
    (3) Chemical reaction theory The theory holds that chemical fertilizers are less likely to react completely during the granulation process, but will continue to react to form double salts during storage, leading to recrystallization and agglomeration. These reactions are accompanied by exothermic and release of water, which causes a change in the composition of the double salt, resulting in a change in the volume of the particles, resulting in cracking and agglomeration of the product. Through the study of agglomeration of high-concentration compound fertilizer, the theory of plastic deformation is formed. (4) Plastic deformation theory According to this theory, agglomeration is accompanied by deformation, and compression will increase the deformation. The residual heat of the fertilizer that is not completely cooled will be transferred outward from the center of the particle. If the fertilizer particles are squeezed, deformation and agglomeration will result. (5) Diffusion agglomeration theory The above mechanism is relatively mature, but some scholars in the former Soviet Union proposed a completely different agglomeration theory - the mechanism of diffusion agglomeration. The mechanism of diffusion agglomeration is considered to be that the agglomeration of the inorganic compound depends on the shape of the particle or the pore structure formed by the accumulation of the particles. Ions of inorganic substances self-diffuse through these channels and some physical or chemical action

    Hydrazine Hydrate Production Process-New Urea Method​
    The hydrazine hydrate urea production method first dissolves urea in water to form a urea solution, and reacts with sodium hypochlorite and caustic soda in a tubular oxidation reactor in the presence of magnesium sulfate to obtain a crude ruthenium, that is, an oxidizing solution having urea. The cerium content exceeds 2%. . Since the crude oil contains a large amount of impurities such as sodium chloride, sodium carbonate and sodium hydroxide, the crude is removed by vacuum distillation through a five-layer tank, and an aqueous solution containing more than 6% of lanthanum is obtained by a fractionator. Further concentration by evaporator to obtain 40% hydrazine hydrate. The urea process is mature and easy to master, but has many side effects. It must maintain a very low bismuth concentration (typically 2% to 3%), so a large amount of by-products need to be disposed of, and the evaporated hydrazine hydrate needs to consume a large amount of heat. To this end, the production process of the hydrazine hydrate urea method has been improved: the production of sodium hypochlorite in the packed absorption tower; the use of a tubular heating reactor instead of the tank reactor to synthesize hydrazine hydrate, which is beneficial to increase the yield; Replace the five-layer evaporator. US evaporation; replacing the liquid inlet column with a gas inlet column to increase the concentration and reduce steam consumption; cooling the hydrated crude solution. However, sodium carbonate decahydrate was recovered, and sodium chloride by-products were recovered, which reduced production costs and improved the quality and stability of hydrazine hydrate.

    Detailed Description of Hydrazine Hydrate Application
    Direct application of hydrazine hydrate 1. Used as an anti-corrosion additive for circulating water in thermal power plants and nuclear power plants; (2) Deoxidation and decarburization cleaning agent for boiler and reactor. Hydrazine hydrate is a deoxidizer that reduces dissolved oxygen in water and is used to further remove dissolved oxygen remaining in boiler feed water after thermal deoxidation. Since dissolved oxygen in the feed water can cause corrosion of the boiler tube wall, the addition of hydrazine hydrate to the boiler feed water can not only deoxidize, but also prevent the formation of iron and copper scale in the boiler. 2. Synthetic chemical raw materials 1. Blowing agent: azoformamide (ac), azocarbonic acid amide, sodium azide, sulfonium tosylate, d1pa, tsh, etc.; 2.

    Morpholine as Metal Corrosion Inhibitor
    The application of morpholine as a metal corrosion inhibitor has the following aspects: (1) Used as a metal gas rust inhibitor. As a metal gas rust inhibitor, morpholine is widely used in mechanical instruments, automobiles, medical equipment and other fields to prevent metal from being corroded by the atmosphere. The metal atmospheric rust inhibitors dicyclohexylamine nitrite and cyclohexylamine carbonate used at home and abroad are highly toxic to humans and the environment, which restricts the promotion and application of gas phase rust inhibitors. As a metal vapor liquid corrosion inhibitor, morpholine has low toxicity and good development prospects. (2) Boiler and water circulation system. Morpholine has similar properties to secondary amines, is weakly alkaline, neutralizes carbonic acid in acidic aqueous solutions, and is widely used as a corrosion inhibitor for boilers and other water recycling systems. The morpholine state of any of the medium and high pressure systems remains stable. The vapor pressure of morpholine is similar to that of water and can be dissolved in water arbitrarily, so the system can maintain a constant ph. morpholine is often used with other amines to solve specific corrosion problems. (3) Used as an antiseptic additive. In lubricating oils, paints, metal cleaners, paint strippers and 1,1,1-trichloroethane, a certain amount of morpholine or morpholine derivatives are often added as corrosion inhibitors, such as N, N-polysulfide. Dimorpholine, N,N-cycloalkyldimorpholine and poly(4-morpholinomethyl)phenol. It can effectively prevent corrosion of running equipment parts. At the same time, it can also be used as an antioxidant for lubricating oils. The addition of N-tert

    Morpholine III
    Morpholine is used as a metal corrosion inhibitor in foreign countries. It is mainly used as a metal gas rust inhibitor to prevent metal from being corroded by the atmosphere. It is widely used in machinery, automobiles, medical equipment and other fields. China has just started in this field. Metal atmospheric rust inhibitors such as dicyclohexylamine nitrite and cyclohexylamine carbonate used at home and abroad have great toxicity to human body and environment, which limits the promotion and application of gas phase rust inhibitors. As a metal gas liquid corrosion inhibitor, morpholine has the advantage of low toxicity. Has a good development prospects. With the development of China's petrochemical industry, it will provide high quality and low price raw materials for the production of morpholine, reduce the price of morpholine, and is conducive to the application of metal anticorrosion. Further, morpholine can also be used as a pH adjuster, a gas absorbent, a synthetic herbicide, and the like. China should also strengthen the development and research of morpholine to promote the consumption of morpholine. In recent years, the new polymer monomer, morpholine, which has developed rapidly in recent years, is also worthy of attention. The acrylate is reacted with morpholine to obtain morpholine acrylate. It is used to modify aqueous polymers and has good compatibility with various prepolymers and polyacrylamides. As application research deepens, many new specific uses will be developed.

    Morpholine I
    Morpholine is an important fine chemical used in rubber vulcanization accelerators NOBS and OTOS, rust inhibitors, preservatives, detergents, descaling agents, analgesics, local anesthetics, fruit preservatives, textile auxiliaries, etc. Preparation. Widely used in rubber, medicine, pesticides, dyes, coatings and other fields. The main production methods of morpholine are the diethanolamine method and the diethylene glycol method. The diethanolamine method is a traditional production method, which requires the import of diethanolamine raw materials, high price, low reaction yield, high production cost, and the product is no longer competitive. The ethylene glycol method is a newly developed morpholine production method in recent years. Diethylene glycol and liquid ammonia are used as raw materials. The process is simple, the conversion rate is high, and the source of diethylene glycol is sufficient. In particular, synthetic ammonia plants use liquid ammonia and hydrogen to develop morpholine. The advantage is that 2/3 domestic manufacturers use this method to produce morpholine. With the rapid development of China's rubber industry, especially the tire industry, the production of morpholine has been stimulated and promoted. Morpholine has become a popular fine chemical product in China. Many scientific research institutions have carried out a lot of research on their synthetic processes, which has set off a boom in the construction of morpholine in China. At present, morpholine not only has a great leap in the quantity and quality of our products, but also the synthetic process has been improved from the traditional diethanolamine strong acid dehydration method to the widely used diethylene glycol

    Morpholine II
    As a metal corrosion inhibitor, morpholine is mainly used for anticorrosion of metals such as iron, copper, zinc and lead. China is just in its infancy. In terms of solvents, surfactants, fluorescent whitening agents, textile auxiliaries and catalysts, China has also started late. Morpholine is mainly used in synthetic rubber vulcanization accelerators (NOBS, OTOS, 26) and the like. Among them, it is mainly used for the synthesis of NOBS. Before the 1990s, the consumption of rubber vulcanization accelerators in developed regions such as Europe, the United States and Japan accounted for more than 50% of the total demand for morpholine. Currently, more than 30% of China's consumption is spent on NOBS. In recent years, the toxicity of promoters harmful to nitrosamines in rubber processing has been noted internationally. Many restrictive regulations have been introduced in the world. For example, Germany issued regulations to control nitrosamine levels as early as 1982. Japan, France and the United Kingdom are actively developing new vulcanization accelerators that do not produce nitrosamines, and have successively stopped using vulcanization accelerators that produce nitrosamines. Therefore, the consumption of exogenous morpholine decreases with the inhibition of the promoter NOBS. Although China does not have a corresponding ban on NOBS, China has joined the WTO. Due to the large amount of foreign tires entering and the localization of the required additives, China's rubber vulcanization accelerators also need to be environmentally friendly. NOBS was replaced with a non-toxic accelerator. The trend of the times. In recent years, China's demand for NOBS has decreased significantly. According to the National Tenth Five-Year Plan for Rubber Additives, by 2005, China will basically not use secondary amine accelerators that decompose nitrosamine

    HEDP
    HEDP is an organic phosphonic acid scale and corrosion inhibitor. It forms stable complexes with various metal ions such as iron, copper and zinc and dissolves oxides on metal surfaces. It can still play a good role in corrosion inhibition and scale inhibition at 250 °C. It is stable at high pH and is not easily hydrolyzed. Decomposition under light and heat conditions is not easy. Acid and alkali resistance and chlorine oxidation resistance are superior to other organic phosphonic acids (salts). It forms a hexacyclic chelate with metal ions in water, especially calcium ions, so it has better scale inhibition effect and obvious dissolution effect. It exhibits the desired synergistic effect when used in combination with other water treatment agents. . HEDP solids are high-purity products suitable for use in cold winter areas, especially in the electronics industry, as detergents and household chemical additives. Hedp is widely used in industrial circulating cooling water systems, such as electricity, chemicals, metallurgy, fertilizers, and scaling and corrosion of medium and low pressure boilers, oil-injected water and oil pipelines; in the textile industry, it can be used as a cleaning agent for metals and non-metals. , a peroxide stabilizer and a fixer for the bleaching and dyeing industry, a compounding agent for the cyanide electroplating industry, and a radioactive element carrier for the pharmaceutical industry. The concentration of HEDP as a scale inhibitor is 1×10 mg/L, the concentration of the corrosion inhibitor is 10×50 mg/L, and the concentration of the cleaning agent is 1000×2000 mg/L. When used in other industries, t

    Phosphate Market in China
    According to industry media reports, the price of phosphate rock in Guizhou Province rose sharply last week. The price of phosphates (including tax) of Grade 29 and Grade 30 in Guizhou Province increased by 80 yuan to 470 yuan / ton and 500 yuan / ton respectively. The tax rate for the cat card has increased by 80 yuan to 570 yuan per ton, and the new price was implemented on December 5. In terms of inventory, phosphate deposits have continued to decline since 2017 and have fallen to historically low levels by the end of 2017. Although phosphate rock stocks rebounded at the beginning of this year, the decline in phosphate rock production in the first half of the year led to a sharp decline in inventories. After entering the fourth quarter, phosphate rock stocks continued to decline. After entering November, the downstream phosphate fertilizer market entered the traditional winter fertilizer season, and the subsequent demand for phosphate rock is about to open. At the same time, due to factors such as climate cooling and environmental protection, some mines in Hubei and Guizhou will face production stoppage. The agency expects that there will be a gap in domestic phosphate mine supply in the fourth quarter, and phosphate rock prices are expected to continue to rise.

    The Global Crude Oil Market is Cloudy
    The fluctuation of the short-term crude oil market is mainly affected by the macro risk aversion caused by Sino-US trade friction and the geopolitical tension in the Middle East. The overall fluctuation is large and the direction is uncertain. The internal INE crude oil is affected by the depreciation of the RMB and the tight supply of heavy oil. Stronger than crude oil in the outer disk. The medium-term leading oil price trend is still the supply side. The logic of the oil price increase in the first four months of this year is the continuous contraction of the supply side. However, at present, this logic has begun to change. In the future, the traditional oil-producing countries will increase production to make up for Iran, Venezuela, etc. The country's unplanned supply decline is expected to be strong, while the US shale oil output is also expected to accelerate. The logical switch means that the mid-term market price of oil will reverse and is expected to form a stage top. The geopolitical situation is tense and the US-Iranian relationship continues to deteriorate. The recent geopolitical situation has continued to strain and the changes in the sentiment of the crude oil market and the volatility of the market. The United States has terminated Iran`s sanctions exemption, and the potential Iranian supply disruption crisis has worried the market. In fact, since the middle of last year, Iran`s crude oil production and exports have shown a significant decline. In November last year, the United States announced that it would restart sanctions against Iran. Fortunately, countries and regions that mainly import Iranian crude oil have been granted immunity, making Iran`s crude oil export normally. Not completely cut off, but the decline is still obvious. In March of this year, only China, India, Turkey and Japan were importing Iranian crude oil, and China accounted for 60%. At present, Iran`s crude oil exports ar

    International Energy Agency Cuts Global Oil Demand Growth Forecast
    The Paris-based International Energy Agency released a monthly crude oil market report on the 15th, which lowered the global average oil demand growth forecast for 2019 by 90,000 barrels to 1.3 million barrels. The report predicts that global oil demand will reach 10 billion barrels per day on average in 2019. The report said that the current US sanctions against Iran and Venezuela, the situation in Libya, and the pollution of Russia's oil pipelines to Europe have caused great uncertainty in global crude oil supply. According to the report, global oil supply fell by an average of 300,000 barrels per day in April to 99.3 million barrels. Among them, Canada, Kazakhstan, Azerbaijan and Iran have the largest declines in supply.

    Affected by Negative Market Chemical Varieties are in Weak Position
    Affected by many factors at home and abroad, the overall volatility of the domestic commodity market has recently increased. As of yesterday afternoon's close, chemical stocks closed down, PTA and ethylene glycol fell first, the main plate fell 4.40% and 4.35%. Analysts said that the weakness of chemical varieties is mainly affected by negative market sentiment and will remain volatile in the short term. Changes in upstream supply and demand of crude oil and downstream construction are the focus of medium and long-term concerns. For the recent decline in chemical varieties, Xing Binbin, an analyst at Yide Futures Methanol, said there is no big bad news about methanol fundamentals, but the market has strong negative expectations for cotton, cotton yarn, polyester and other industrial chains. [Market sentiment is weak, long-term demand is expected to be pessimistic. Textile raw cotton and cotton yarn have fallen for two consecutive days. Chemical fiber raw materials PTA and ethylene glycol have also fallen sharply. Yesterday`s trading hit a stop loss." Zhang Xiaozhen, a researcher at Guangfa Futures Chemicals, said that PTA, in addition to macro factors The fundamentals of ethylene glycol are also weakening. From the point of view of pta demand, she believes that the current terminal demand is entering the off-season, the order situation is not good, resulting in increased gray cloth inventory, the construction of looms and loaders is declining, and the demand for downstream polyester is also weakening. "Because the terminal demand has been weak for a period of time, it is gradually shifting to polyester. In addition, the raw material pta spot price is strong, the polyester processing profit is grea

    Ethylene Glycol is Difficult to Get Rid of the Weak Pattern
    Terminal demand has not improved, and polyester companies may actively reduce operating rates. In addition, despite the decline in ethylene glycol stocks in East China in the past two weeks, overall inventories are still at historically high levels. Ethylene glycol prices are expected to continue to be in short selling. Limited by its own fundamentals, since the listing of ethylene glycol futures on December 10 last year, prices have shown a downward trend. Factory operating rate is still very high Since the beginning of this year, the operating rate of ethylene glycol plants in China has been maintained at a relatively high level. Although it has encountered the Spring Festival holiday, it has little effect on the start-up of ethylene glycol devices. At the end of April, the coal-based ethylene glycol plant was intensively overhauled. As of April 26, the weekly operating rate of ethylene glycol plants was 81.59%, down 0.97% from the previous month and up 5.59% from the same period last year. As of April 30, the operating rate of weekly coal-based ethylene glycol units was 55.01%, down 5.35 percentage points from the previous month and down 0.99 percentage points from the same period last year.

    The Environmental Industry will Further Integrate Technology Advantages as The Key
    In recent years, with the release of pollution control demand, the development of China's environmental protection industry has accelerated, and the number of enterprises has increased dramatically. With the intensification of industrial competition, the importance of technology has become more prominent, and the trend of industrial integration has emerged. According to the [China Environmental Protection Industry Development Report" (2018) issued by China Environmental Protection Industry Association, it is estimated that the total operating income of China's environmental protection industry will exceed 2 trillion yuan in 2020. The growth rate of the environmental protection industry is much higher than the growth rate of the national economy. At the 20th China World Expo held in April, a total of 2,047 exhibitors participated, an increase of 17% over 2018.

    Early morning crude oil diving continued into the night: one day fell more than 6%
    From 2 am on April 27, the high oil prices in the domestic and international markets plummeted. Since then, oil prices have weakened throughout the day. From the European trading period starting at 4 pm, oil prices continued to fall sharply. Both WTI and Brent markets have fallen more than $4 from their intraday highs, and a 6% drop in a single day is a collapse. By the end of the day, oil prices have fully recovered from the past week. Technically, it constitutes a typical form of roof roof. Although this week's domestic INE crude oil futures have obvious complementary actions compared with the external market, the relative resistance of the performance has declined, but it has also recovered most of the increase. After the oil price plummeted, market investors immediately sought a reasonable explanation. Trump then revealed to reporters on Friday that he had called the Organization of Petroleum Exporting Countries (OPEC) to ask the organization to lower the price of crude oil. But the above did not say who he was on the phone. After receiving this information, oil prices continued to fall rapidly. The market generally believes that this statement is the fuse of the oil price collapse on Friday night, but the market media said in the early morning that OPEC Secretary General, Saudi Crown Prince and the Minister did not talk to him. The oil price sighed a little from the recession and fell slightly, but it still recorded the biggest one-day drop in a year. The sharp drop in oil prices and news from the news indicate that investors are more hesitant about market expectations after the deterioration of Iranian sanctions and the expected increase in OPEC, and their mentality is not stable.
