PROBLEM TO BE SOLVED: To provide a process for producing cyclohexanone oxime by which the oxime is produced in a high yield and the deterioration of a titanosilicate catalyst, particularly the lowering of its catalytic activity is controlled in the ammoximation reaction of cyclohexanone. SOLUTION: The process comprises reacting cyclohexanone, hydrogen peroxide and ammonia in the presence of titanosilicate and another silicon compound. Silica gel, silicic acid, a silicate and a zeolite other than titanosilicate are used as the silicone compound other than titanosilicate. COPYRIGHT: (C)2004,JPO
