Modern agriculture requires the use of crop protection agents to overcome the huge losses of various pests, from microbes to insects to weeds. Some of the most important crop protection chemicals produced by the world's leading agricultural companies come from hydrazine. These preparations can increase the production of pest-free foods and provide food for the world's population. Bismuth is a highly active bifunctional molecule that can enter the reaction process to produce several biologically active compounds. Some sputum-based ring systems are often found in agricultural agents, including: The main herbicide used in soybeans is Bayer's Encor, which is derived from the triazine ring system. Elanco's Spike< is based on a thiadiazole ring. Maleic hydrazide is used to prevent the growth of sucker from tobacco plants and has been recommended for ornamental tobacco and potato. It is a derivative of the pyridazine ring. These and many other examples can be found in the farm record manual published by meister Publishing, Willoughby, oh 44094.

Inventories of methanol coastal ports continued to decrease by around 43,000 tons to around 945,000 tons. Although the reduction in coastal market stocks was in line with market expectations, the total inventory and decline were not satisfactory. At the same time, although the maintenance work of domestic methanol plants is on schedule, the market supply is not tight, and the supply pattern of the methanol market is still relatively loose in the short term. Considering that the methanol futures price increase lacks fundamental support factors, and further approaches the cost line of some producers, the methanol market is currently in a hollow and deadlock, and methanol futures prices are expected to be dominated by shock consolidation. Recently, most production companies have mainly increased their exit and repatriation funds, and the spot price has also undergone a certain degree of adjustment. From the demand side, the orders of downstream processing enterprises have improved recently compared with last month. The stock willingness of some regional traders and processing enterprises has increased slightly, and market confidence has improved. In addition, the upcoming price coordination meeting in some regions will also boost market confidence. Overall, short-term glass prices will show strong momentum. PTA futures prices have fallen sharply recently, mainly due to the continued sharp drop in PX prices. The market expects that the second line of Hengli will be put into production ahead of schedule, which is the direct link factor for the continued decline of PX. In addition, refining and chemical projects including Hengyi Brunei, Sinochem and Hainan are expected to be put into operation in the middle of this year, which also aggravat

It is estimated that by 2005, global OAP demand will grow by an average of 3.7% per year, and in 2005 it will reach 28.3 million tons. The demand for ortho amino phenol in more mature industrialized countries is growing at an average annual rate of 2.7%. The growth in 2-aminophenol demand in developing countries will be higher than the world average. China will grow at a rate of 6.6% per year, reaching about 3 million tons in 2005. This means that there is a lot of room for the development of Chinese paint. According to reports, in 2003 China's paint production exceeded 2.2 million tons, an increase of 10% over the same period of last year; among them, the output of 2-aminophenol reached 520,000 tons, an increase of 15% over the same period last year. With the development of the western region, the construction of Olympic venues, the increasing number of key projects and residential areas, and the introduction of relevant policies, the ortho amino phenol industry will maintain rapid growth in the next few years. However, with the development of the economy and the improvement of people's living standards, the restrictions on volatile organic compounds and toxic substances in various countries are becoming more and more strict, and the optimization of resins and formulations and the development of suitable additives are becoming more and more strict. In the 1990s, there was a [green revolution" in the international market, pushing the paint industry to [green". At present, environmentally friendly [green" coatings have become the mainstream development direction of the market, and the market share has increased year by year. At present, more than 100 water-based coatings produced by 30 enterprises in China have reached the new certification standard of the [China Environmental Labeling" of the State Environmental Prot

Industry experts such as "Gong Liucheng" suggested that during this period, in the process of improving the production of air-conditioning foaming agents, it is necessary to strengthen the research and development, specialization and improvement of new air-conditioning blowing agents, and strengthen the comprehensive utilization of [three wastes]. Meanwhile. Gong Liucheng said that China's exchange foaming agent industry is facing enormous challenges and good development opportunities. If it can effectively improve the raw material route, improve its technical level. Accelerate the development and application of product transformation, improve the overall level of the industry, and become the advantage of quality and variety. China's exchange foaming agent industry still has good development prospects.

Reactive dyes, also known as reactive dyes. A dye that chemically reacts with fibers during the dyeing process. This dye molecule contains a group capable of chemically reacting with the fiber, and the dye reacts with the fiber during the dyeing process to form a covalent bond between the two to form a whole, which improves washing and rubbing fastness. Reactive dyes are a new class of dyes. In 1956, the first production of Procion grade reactive dyes in the UK. The reactive dye molecules include the two main components of the parent dye and the reactive group, and the groups reactive with the fiber are referred to as reactive groups. The properties of reactive dyes are as follows: First, solubility Excellent water solubility is used in the quality of reactive dyes. The solubility and concentration of the prepared dye is related to the size of the selected tank, the amount of electrolyte added, the dyeing temperature, and the amount of urea used. The solubility of reactive dyes varies widely. See each theory. The solubility listed is the range allowed when using the dye. For reactive dyes used for printing or dyeing, a variety having a solubility of about 100 g/l should be selected. The dye should be completely dissolved, not turbid, and not painted. Hot water can accelerate the dissolution, and urea has the function of melting, salt, yuanming powder and other electrolytes, which will reduce the solubility of the dye. The reactive dye is not dissolved with an alkaline agent to prevent hydrolysis of the dye. Methods for determining the solubility of reactive dyes include

Here we can use the classification of fluorescent whitening agents as a general guide, we can know if we have chosen the type of fluorescent whitening agent that suits our application. 1.Responsiveness If bleeding, the OBA should be compatible with plastic. OBA for thermoplastics requires higher heat resistance and lower volatility than textiles. 2.Light Resistance Fluorescent fluorescent whitening agents have limited lightfastness, much lower than pigments and most plastics. In any event, photochemical degradation of the optical brightener should not cause the plastic to turn yellow. 3.Hue In most cases, people prefer medium blue instead of blue-green instead of red. 4. Processing conditions In order to maximize the whitening effect, it should be fully decomposed or evenly distributed to the product. 5. Other components Other components of the system, such as pigments, UV absorbers, and titanium dioxide pigments (TiO2), absorb light in the same UV wavelength range as fluorescent whitening agents, thereby reducing the whitening effect of resveratrol. The anatase titanium dioxide pigment absorbs approximately 40% of the 380 nm i

China is the world's largest producer and supplier of AC (azodicarbonamide) foaming agents with an annual production capacity of 150,000 tons, accounting for about 50% of the world's total capacity. The actual annual production exceeds 110,000 tons. However, Gong Liucheng, deputy director of the Plastics Additives Special Committee of the China Engineering Plastics Association, recently pointed out at the 2007 Nanchang University of Technology Plastics Additives Production and Application Conference that China is the world's largest producer of plastic additives. AC foaming agent. However, it is far from a strong country. There is still a long way to go from a big country to a strong country. To some extent, this statement is also the same as China's hydrazine hydrate, anhydrous ferric chloride, 2-aminophenol, PVC and other chemicals. AC foaming agent is widely used in the foaming of PVC, PE, PP, EVA, PS, ABS and other resin and rubber products. It is the world's largest chemical foaming agent. Due to its high quality and low price, wide application range, and good physical and chemical properties, there is no chemical foaming agent that can compete with it. The foaming agent mainly produced in China is an AC foaming agent. The actual domestic demand is 80,000-90,000 tons/year. Consumption structure: PVC 40%, PE 35%, PP 12%, rubber 5%. Others accounted for 8%, and there are more than 30 production enterprises. The backbone enterprises mainly include Jiangxi Dehua Fine Chemical Co., Ltd., Jiangsu Sopro Chemical Co., Ltd., Ningxia Sheng Industrial Co., Ltd., Fujian Longyan Longhua Group Co., Ltd.; 24,000 tons, mainly exported Southeast Asia, Japan, South Korea, Russia. Singapore Airlines and other places.

Bi-amino derivatives are used in the manufacture of herbicides and fungicides, as well as plant growth regulators. Bisamino derivatives have been shown to be active ingredients in many drugs, from sedatives to major drugs that control tuberculosis. As an oxygen scavenger in boiler water, SCAV-Ox® 35% rhodium solution reduces oxidation in low pressure and high pressure steam systems. In fact, helium is the best oxidation-preventing material in supercritical boilers with pressures up to 3,500 psi. Currently, hydrazine derivatives are widely used in the production of blowing agents and polymerization initiators in the plastics industry. The use of these derivatives in polymer formulations has also been investigated. Propellant It is the main fuel component of the Titan series of consumable launch vehicles (ELVs). The oxidant spontaneously ignites when mixed with hydrazine. Satellites and other spacecraft use ultra-pure one-component propellants to navigate in orbit.

The urea of the same mixed nitrogen fertilizer ring is closely related to ferric chloride anhydrous. The market trend may be the same, the price will affect anhydrous ferrous chloride, and ferric chloride (FeCl3) can be replaced to some extent in the compound ferric chloride and ferric chloride synthesis. Of course, this is well known and does not need to be repeated. Therefore, the development trend of urea is particularly important for Iron III Chloride enterprises. In recent years, the urea market has risen again and again, and prices have fluctuated. At present, the price of urea plants, transaction prices, and wholesale prices at the grassroots level have all fallen. Large, medium and small farmers have said that there are prices in the market where there is no market. The next step is mostly short-term. At this point, the Iron III Chloride enterprises pondered, worried that the fall in urea prices would "intervene" anhydrous ferrous chloride, and worried that 80% of the ferric chloride opening would be double hit? The domestic powder ferric chloride market has generally improved. The spot is tight, and most companies are waiting for the end of the month or mid-May. Most companies still need to control orders or have not received orders in

As a responsible listed company, Forever Chemical has the courage to assume social responsibility and pay full attention to environmental protection. We develop 100%, 80%, 64% and 55% hydrated hydrazine, ADC blowing agents, OBA and OAP products. In 2008, it passed ISO 14001; 2004 environmental management system certification. The cleaner production audit was approved in 2011. According to the circular economy model, the chemical production line has always been established. The hydrazine hydrate is prepared using the produced sodium caustic soda. The ADC foaming agent was prepared using hydrazine hydrate. Ammonia water, ADC foaming agent by-products are used for hydrazine hydrate and thermal electrical denitration. Caustic soda produces chlorine gas for CPE production. Hydrogen dioxide is used to treat hydrogen peroxide, which can be used to treat industrial wastewater. Through this circular economy model, the chlor-alkali balance and cyclical connection between new and old industries are realized. The unity of environmental, social and economic benefits has been achieved. In 2019, we will continue to increase investment in environmental protection. It is planned to build a new desulfurization absorption tower. And made a profound dust removal transformation. 1, no. 2 boiler dust collector. Continue to the next stricter emission standard.

Fluorescent whitening agent (OBA) or fluorescent whitening agent (FWA) is a colorless to weakly colored organic compound that absorbs ultraviolet light and absorbs most of the absorbed energy in a solution or matrix, such as between 400 and 500 nm. Blue fluorescence. From the human eye, the substance that uniformly reflects most of the light at all wavelengths of its surface is white. For example, natural fibers typically absorb more light in the blue region of the visible spectrum ("blue defects") because they contain impurities (natural pigments). Therefore, natural fibers exhibit unwanted yellow castings. Synthetic fibers also have this pale yellow casting, although not very obvious. The whiteness of the substrate can be improved by (1) increasing reflection (reflectance) or (2) compensating for blue defects. Bleaching has these effects to some extent, but always leaves a portion of pale yellow gypsum. Even the most thorough bleach does not remove all traces of yellow castings. Prior to the appearance of optical brighteners (OBA), it is common practice to apply a small amount of a blue or violet dye (referred to as "blue") to enhance the visual impression of whiteness. . These dyes absorb light in the green-yellow region of the spectrum, thereby reducing brightness. However, since they change the hue of the pale yellow material to blue, the human eye feels an increase in whiteness. Unlike dyes, fluorescent whitening agents can counteract yellow light polarization and increase brightness because their blue effect is not based on subtracting yellow and green light, but on increasing blue light. Fluorescent whitening agents (OBA) are actually a colorless compound. When it is present on the s

Although China's AC foaming agent exports are large, the main raw material powder is exported, and the profit is very low. The technical level of domestic products is very different from that of foreign products: ketone nitrogen or hydrogen peroxide is widely used in foreign countries, but China still uses urea technology, facing elimination, wasting resources, and seriously polluting the environment; domestic production technology is slow, and emissions are [three-way" The amount of [waste" is large and difficult to control. Most companies can only produce raw material powder and cannot produce high-profit modified products. product. This makes China's AC foaming agent industry always at the low end of global market competition. At present, the actual situation of the domestic foaming agent industry is that on the one hand, the production capacity is continuously expanding, on the other hand, the competition is intensifying, which directly affects the continuous decline in sales prices and sales prices in some regions, and has dropped to 13,000 yuan/ton. Since December last year, the export prices of major producers` products have risen to more than 2,000 US dollars per ton, but still below the import price of more than 700 US dollars. Competition is mainly concentrated on low-end products, and the lucrative transformation is in the field of AC foaming agents, involving few domestic companies. The modified air-conditioning foaming agent process basically has no [three wastes", the investment is small, and the added value of the modified products is greatly improved. At present, hundreds of varieties have been developed abroad, such as Japan's pvc modified exchange brand has nearly 20 kinds, and new varieties have emerged.

1) How to choose polyolefin fluorescent whitening agent? 2) How to choose PVC fluorescent whitening agent? It is worth noting that the same fluorescent whitening agent has different whitening effects on rigid polyvinyl chloride (R-PVC) and flexible polyvinyl chloride (FPVC). A bisbenzoxazole or phenylcoumarin group is commonly used for polyvinyl chloride. When the polyvinyl chloride powder, the heat stabilizer and the fluorescent whitening agent are mixed and dried, the fluorescent whitening agent is uniformly distributed. For flexible PVC, OBA dissolves or disperses in the plasticizer. It is best to add FWA in the form of a master batch. Fluorescent whitening agents and plasticizer masterbatches or OBA and PVC masterbatches are used when transporting PVC.
