Market application of hydrazine hydrate in chemical industry and other fields

　　Hydrazine hydrate, as an important microbiological chemical product, is used to transform AC, D1PA and TSH into foam plastics. It is also used as the removal and modification material of ammonia and carbon dioxide in heat treatment furnace and reactor; It is used in the pharmaceutical industry for the production and treatment of anti tuberculosis and anti diabetic drugs. In the industrial production of organic fertilizer, it is used to produce and process herbicides, plant growth blending agents and bactericidal, insecticidal and rodenticides; In addition, it can also be used to produce and process rocket fuel, diazo natural materials, rubber additives, etc. In recent years, the application scope of hydrazine hydrate is still expanding.

　　1. Application of hydrazine hydrate

　　① : anti-corrosion additive used as refrigeration cooling circulating water in power plants and nuclear power plants;

　　② : deaerator for drinking water in heating furnace and high pressure steam furnace. Hydrazine hydrate is a kind of deaerator, which can reduce the dissolved oxygen in water and is used to further remove the residual small amount of dissolved oxygen in the water supply and drainage of heat treatment furnace after heating and deaeration. Because the dissolved oxygen in the water supply and drainage will lead to the corrosion of the wall thickness of the heat treatment furnace. Adding hydrazine hydrate to the water supply and drainage of the heat treatment furnace can not only remove ammonia, but also prevent the conversion of iron scale and copper scale in the heat treatment furnace.

　　2. Conversion into chemical products

　　1: foam glue: formamide formamide (formamide carbonamide), for example: sodium azide products used for the production of tires.

　　② : the conversion of bioactive chemical intermediates in bio organic fertilizer products and pharmaceutical products to triazole;

　　③ : formamide initiator;

　　4. Every kind of other products: some unique organic pigments in the dye, photographic reagents, carbamate and acrylic emulsion products, and cyanobromate products.
