Hydrazine is produced by oxidation of NH 3 or urea by hypochloride. It is used in organic synthesis, as a component of liquid rocket fuels, and in the production of plastics, cured rubber, insecticides, and explosives.Audrieth, L., and B. Ogg.ydrazine is an endothermal compound; heat of formation Î´H (1) = 50.24 kilojoules per mole (12.05 kilocalories per mole). Upon heating to 200Â°-300Â° C, hydrazine decomposes to N 2 and NH 3. In the presence of Fe 2 0 3, it ignites at room temperature.
