Hydrazine 38 (inorganic compound)

Hydrazine hydrate(pinyin:jǐng),also known as hydrazine hydrate,is an inorganic compound with the chemical formula N2H4·H2O.It is a colorless and transparent smoking liquid with a light ammonia smell.It emits smoke 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 a dimer,miscible with water and ethanol,and insoluble in ether and chloroform;It can corrode glass,rubber,leather,cork,etc.,and decompose into N2,NH3,and H2 at high temperatures;Hydrazine hydrate has extremely strong reducibility and reacts violently with halogen elements,HNO3,KMnO4,etc.It can absorb CO2 in the air and produce smoke.Hydrazine hydrate and its derivatives are widely used in many industrial applications,as reducing agents,antioxidants,pharmaceuticals,foaming agents,etc.
