Abstract
PURPOSE: To prepare highly pure ketazine useful as an intermediate of hydrazine, easily and economically, from a crude ketazine solution containing ketoxime, by adding an alkali or an aqueous solution of an alkali to the ketazine solution, and extracting with an organic solvent.
CONSTITUTION: An aqueous solution of crude ketazine of formula II (R1 and R2 are 1W4C alkyl, etc.) containing a ketoxime of formula I is added with an alkali directly or in the form of an aqueous solution, and extracted with an organic solvent to obtain purified ketazine free from ketoxime.
EFFECT: The affinity of ketoxime to water becomes completely opposite to that of ketazine by the presence of alkali, which enables the selective fractionation extraction of the compounds.
