hydrazine – מילון אנגלי-אנגלי
Hydrazine
Hydrazine is an
inorganic compound with the
chemical formula (also written ). It is a colorless flammable liquid with an
ammonia-like odor. Hydrazine is highly toxic and dangerously unstable unless handled in solution. , approximately 120,000 tons of hydrazine hydrate (corresponding to a 64% solution of hydrazine in water by weight) were manufactured worldwide per year. Hydrazine is mainly used as a
foaming agent in preparing
polymer foams, but significant applications also include its uses as a
precursor to
polymerization catalysts and
pharmaceuticals. Additionally, hydrazine is used in various
rocket fuels and to prepare the gas precursors used in
air bags. Hydrazine is used within both nuclear and conventional electrical
power plant steam cycles as an oxygen scavenger to control concentrations of dissolved oxygen in an effort to reduce corrosion.

Hydrazine
(n.)
Any one of a series of nitrogenous bases, resembling the amines and produced by the reduction of certain nitroso and diazo compounds; as, methyl hydrazine, phenyl hydrazine, etc. They are derivatives of hydrazine proper, H2N.NH2, which is a doubled amido group, recently (1887) isolated as a stable, colorless gas, with a peculiar, irritating odor. As a base it forms distinct salts. Called also diamide, amidogen, (or more properly diamidogen), etc.
