Abstract

PURPOSE: To obtain hydrazine without removing ketone and an org. solvent by distillation by adding an acid to a liq. extract prepared by extracting org. components such as hydrazone or ketazine or ketone in an org. method soln. with an org. solvent.
CONSTITUTION: Org. components such as hydrazine or ketazine or ketone in a liq. reaction product (a synthesized soln.) consisting of an aqueous sodium hypochlorite soln., an aqueous ammonia soln. and ketone are extracted with a water- insoluble or practically water-insoluble org. solvent. The liq. extract is mixed with an aqueous acid soln. or an acid and water to decompose ketazine or hydrazine in the extract into hydrazinium salt and ketone. The resulting liq. mixture is then separated into an org. layer and a precipitate or an aqueous soln. of hydrazinium salt. The org. layer can be recycled to the original system after washing or other treatment without carrying out recovery by distillation.
