Detailed Description of Hydrazine Hydrate Application

2019-05-30

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. Herbicides, plant growth regulators and bactericidal, insecticidal and rodenticides in pesticide products: plant growth regulator maleic hydrazide derivatives, rodenticide dibenzoyl hydrazide, insecticidal nail bactericide pyrazole derivatives , 5-nitrofuran semicarbazone, herbicide aminotriazole, etc.;
3. Pharmaceutical products against tuberculosis and antidiabetic drugs: isoniazid, phenylthiosemicarbazide and benzenesulfonylthiourea, antipsychotic drug 1-isonicotinic acid-2-isopropion hydrazide, anticancer drug aldehyde hydrazide derivative, Anti-infective drug 5-nitrofuroyl hydrazide derivative, antibiotic oxazoline cephalosporin, diuretic antihypertensive drug hydrazide benzoxazine, antitumor drug methyl benzoquinone.
4. Novel polymer initiators, such as liquid azo compound products;
three. Hydrazine hydrate is widely used in the following areas:
1. Separation and manufacture of high-purity metals, synthetic fibers and rare elements, cleaning and refining of precious metals;
2. Recovering metals from pickling solutions and surface treatments;
3. Dispose of waste liquid and waste gas;
4. Purification of refined sulfuric acid in the electronic market;
5. Metal inlays of plastics and metals (nickel, cobalt, iron, chromium, etc.);
(5) Formulation products of rocket fuel and explosives, diazo fuel, and rubber additives;
7, used in the actual process, mainly used for gold ore beneficiation;
8. Used as a reducing agent, antioxidant, etc., for photography, photographic products, etc.;
9, as an analytical reagent
4. A derivative product used in the production of hydrazine hydrate:
1, LIOZAN: anti-corrosion products, can provide fast degassing ability, and can be effective at lower temperatures;
(2) strontium salt: three kinds of products, mainly used in the synthesis of intermediates, especially the pharmaceutical industry;
3. Triazole products: 1,2,4-triazole/1,2,4-triazole sodium salt/4-amino-1,2,4-triazol/3-amino-1,2,4 - triazole, etc.;
