[61][62], The name "hydrazine" was coined by Emil Fischer in 1875; he was trying to produce organic compounds that consisted of mono-substituted hydrazine. provided correct acknowledgement is given. Ideally, the combustion of hydrazine in oxygen produces nitrogen and water: An excess of oxygen gives oxides of nitrogen, including nitrogen monoxide and nitrogen dioxide: The heat of combustion of hydrazine in oxygen (air) is 19.41 MJ/kg (8345 BTU/lb). [52] Hydrazinium hydrogensulfate was investigated as a treatment of cancer-induced cachexia, but proved ineffective. It is also used to reduce metal salts and oxides to the pure metals in electroless nickel plating and plutonium extraction from nuclear reactor waste.
