Hydrazine hydrate as an important fine chemical raw materials, mainly used for synthesis of AC, D1PA, TSH, such as blowing agent; also used as a boiler and the deoxidation reactor and carbon dioxide from the cleaning agent; in the pharmaceutical industry for the production of anti - tuberculosis, anti-diabetic drugs; in the pesticide industry for the production of herbicides, plant growth agents and reconcile sterilization, insecticide, to kill poison; In addition, it can also be used to produce rocket fuel, diazo fuels, such as rubber chemicals. In recent years, applications of hydrazine hydrate is still expanding. Physical and chemical properties of hydrazine hydrate Hydrazine hydrate, also known as hydrazine hydrate. Pure colorless transparent oily liquid. The general application of the content industry is 40% - 80% aqueous solution of hydrazine hydrate or hydrazine salt. Hydrazine hydrate with alkali and moisture absorption. Hydrazine is a colorless, transparent oily liquid, with light ammonium, in the humid air in the smoke, strong alkaline and hygroscopicity. Freezing point -51.7 °C, melting point less than -40 °C, boiling point 118.5 °C, relative density 1.032 (21 / 4 °C, the hydrazine hydrate refers to 21 °C and 4 °C than the density of water), surface tension (25 °C) 74.0mN / m, refractive index 1.4284, heat of formation -242.71kJ/mol, flash point (open cup) 72.8 °C. Liquid hydrazine hydrate to form dimers with the immiscibility of water and ethanol, insoluble in ether and chloroform; it can erode glass, rubber, leather, cork, etc., at a high temperature into N2, NH3 and H2; hydrazine reduction highly, with halogen, HNO3, KmnO4 a violent reaction, etc., in the air can absorb CO2, produce smoke.
