Abstract
Anhydrous hydrazine is prepared by reacting a hydrazine sulphate, preferably the acid sulphate with ammonia in the presence of liquid aliphatic ethers and/or alcohols having a boiling point under atmospheric pressure below 85 DEG C., such as methyl, ethyl and isopropyl alcohol and diethyl ethers. The reaction is preferably carried out below 40 DEG C. or at a higher temperature under increased pressure, and the hydrazine formed may be recovered by distillation of the reaction mixture after the solid residues have been separated.
