Methyl Hydrazine
Methylhydrazines are hydrazines that have additional methyl groups. Heavily methylated versions exist as hydrazinium salts. Members of this class include: * Monomethylhydrazine **Monomethylhydrazinium (cationic and exists as a variety of salts) * Dimethylhydrazines ** Symmetrical dimethylhydrazine (1,2-dimethylhydrazine) ** Unsymmetrical dimethylhydrazine (1,1-dimethylhydrazine) * Trimethylhydrazine ** 1,1,2-trimethylhydrazine ** 1,1,1-trimethylhydrazinium (cationic and exists as a variety of salts e.g. 1,1,1-trimethylhydrazinium iodide) * Tetramethylhydrazine **1,1,2,2-tetramethylhydrazine **1,1,1,2-tetramethylhydrazinium (cationic and exists as a variety of salts) * Pentamethylhydrazinium (cationic and exists as a variety of salts) * Hexamethylhydrazinediium (dication, exists as a variety of salts) External links * {{chemistry index Hydrazines ...

Hydrazine
Hydrazine is an inorganic compound with the chemical formula . It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour. Hydrazine is highly toxic unless handled in solution as, for example, hydrazine hydrate (). Hydrazine is mainly used as a foaming agent in preparing polymer foams, but applications also include its uses as a precursor to polymerization catalysts, pharmaceuticals, and agrochemicals, as well as a long-term storable propellant for in-space spacecraft propulsion. 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. the world hydrazine hydrate market amounted to $350 million. About two million tons of hydrazine hydrate were used in foam blowing agents in 2015. Hydrazines r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
