Introduction to Hydrazine Hydrate - part 1

Hydrazine hydrate, also known as hydrazine hydrate, is an inorganic compound with a chemical formula of N2H4·H2O. It is a colorless, honey-penetrating fuming liquid with a faint ammonia odor. It smokes in humid air, and has strong alkalinity and hygroscopicity. Under normal pressure, hydrazine can form an azeotrope with water (the hydrazine content in the azeotrope is about 69%). Hydrazine hydrate liquid exists in the form of dimer, miscible with water and ethanol, insoluble in ether and chloroform; it can corrode glass, rubber, leather, cork, etc., and decompose into N2, NH3 and H2 at high temperature; hydrazine hydrate has reducibility Extremely strong, reacts violently with elemental halogen, HNO3, KMnO4, etc., can absorb CO2 in the air, and produce smog. Hydrazine hydrate and its derivatives are widely used in many industrial applications as reducing agent, antioxidant, medicine, foaming agent, etc.

As an important fine chemical raw material, hydrazine hydrate is mainly used for the synthesis of foaming agents such as AC, D1PA, TSH, etc.; it is also used as a cleaning treatment agent for deoxidation and decarbonation of boilers and reactors; it is used in the pharmaceutical industry for the production of anti-oxidants. Tuberculosis, anti-diabetic drugs; used in the production of herbicides, plant growth regulators and bactericides, insecticides, rodenticides in the pesticide industry; in addition, it can also be used in the production of rocket fuel, diazo fuel, rubber auxiliaries, etc.
