Summary:There is provided a method for producing an oxime compound, which is characterized by the steps of: (a) oxidizing cumene to produce cumene hydroperoxide, (b) subjecting the cumene hydroperoxide to an ammoximation reaction with ammonia and a ketone in the presence of a catalyst to produce a reaction mixture containing an oxime compound corresponding to the ketone and 2-phenyl-2-propanol, (c) separating a fraction of 2-phenyl-2-propanol and the oxime compound corresponding to the ketone from the reaction mixture resulting in the step (b), (d) converting 2-phneyl-2-propanol in the fraction to cumene, and (e) recycling at least a portion of the cumene resulting in step(d) to step (a).
