ABSTRACT:
In producing cyclohexanone oxime by a method comprising the step of reacting cyclohexanone, hydrogen peroxide and ammonia in the presence of titanium silicate, a brand-new titanium silicate and a recycled titanium silicate which has been recovered from a production method of cyclohexanone oxime are used. In accordance with the present invention, cyclohexanone is subjected to ammoximation by hydrogen peroxide and ammonia with suppressing the degradation- of titanium silicate as a catalyst, to produce cyclohexanone oxime with a high yield.
