Abstract

A process for the preparation of an oxime, comprising introducing into a contact zone a stream of a solution of a cyclic ketone of 4 to 8 carbon atoms in a solvent for said ketone immiscible with water or slightly miscible with water said solvent being also a solvent for the oxime reaction product, and introducing into said reaction zone a stream of an aqueous solution of the hydroxyl ammonium salt of a weak acid, in a countercurrent relation to the aforementioned dissolution stream of cyclic ketone of said zone, said aqueous stream containing a soluble salt of said weak acid, to give, with the free acid produced in the reaction zone, a buffered reaction medium, and discharge from the reaction zone, a product stream of oxime dissolved in said solvent thereof, and an aqueous stream containing free acid, separating the solvent from said product oxime, and recycling the solvent thus obtained to said reaction zone.
