GENERAL DESCRIPTION AND APPLICATIONS |
||
Hydrazine (anhydrous) is a clear, fuming, corrosive liquid with an ammonia-like odor; melting at 1.4 C, boiling at 113.5 C, specific gravity 1.011. It is very soluble in water and soluble in alcohol. It decomposes on heating or exposure to UV to form ammonia, hydrogen, and nitrogen, which may be explosive with a blue flame when catalysed by metal oxides and some metals such as platinum or Raney nickel. It is prepared from ammonia with chloramine in the presence of glue or gelatin (to inhibit decomposition of the hydrazine by unreacted oxidants) as the hydrate form usually (100% monohydrate contains 64% by weight hydrazine). Hydrazine is also prepared from sodium hypochlorite with urea in the presence of glue or gelatin. Hydrazine is used as a component in jet fuels because it produce a large amount of heat when burned. Hydrazine is used as an oxygen scavenger for boiler feed water to prevent corrosion damage. Hydrazine is used as a reducing agent for the recovery of precious metals and as a chain extender in urethane coatings. Hydrazine is dibasic and very reactive. It and its derivatives have active applications in organic synthesis for agrochemicals, pharmaceuticals and stabilizers, polymerization catalysts, flame-retardants, blowing agents for plastics. Acetone Thiosemicarbazone is used as an intermediate in the manufacture of pesticides and pharmaceuticals. |
