METHOD FOR PRODUCING CYCLOHEXANONE OXIME

摘要

PROBLEM TO BE SOLVED: To produce cyclohexanone oxime stably for a long time by the ammoximation reaction of cyclohexanone.

SOLUTION: Cyclohexanone oxime is produced by performing the ammoximation reaction of cyclohexanone with hydrogen peroxide and ammonia in the presence of titanosilicate and a solid containing a silicon compound. The solid containing a silicon compound is one that had been used as a catalyst in a Beckmann rearrangement reaction of cyclohexanone oxime.
