    Abstract: A process for the production of oximes of cycloaliphatic ketones having at least 12 carbon atoms by action of hydroxylamine on the ketone in an aqueous heterogeneous reaction mixture is effected at an elevated temperature (e.g. 50-150 DEG C.) and at pH 6-14, and is further characterized by the requirement that the aqueous phase contains at least 10% wt. of salt after the reaction is over. A water-immiscible inert solvent b.p. above 10 DEG C. may be present during the reaction or an inert solvent may be added after the reaction to dissolve the oxime formed. U.S.A. Specifications 2,270,204, 2,756,258, 2,820,825, German Specifications 857,375, 888,693, 1,081,884 and 1,042,575 are referred to.
