Hydrazine hydrate is a colorless transparent oily liquid with a faint ammonia odor. In industry, hydrazine hydrate aqueous solution or hydrazine salt with a content of 40% to 80% is generally used. Relative density 1.03 (21 ℃); melting point - 40 ℃; boiling point 118.5 ℃. Surface tension (25°C) 74.0mN/m, refractive index 1.4284, heat of formation - 242.7lkj/mol, flash point (open cup) 72.8°C. Hydrazine hydrate is strongly alkaline and hygroscopic. 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 Nz, NH3 and Hz at high temperature; hydrazine hydrate has reducibility Extremely strong, reacts violently with halogen, HN03, KMn04, etc., can absorb C02 in the air, and produce smoke.
