Process for producing cycloalkanone oximes

摘要

The present invention provides a process for producing a cycloalkanone oxime by conducting a continuous ammoximation reaction in the presence of a titanosilicate catalyst with supplying a cycloalkanone, hydrogen peroxide, ammonia and an organic solvent into the reaction system, wherein the reaction temperature is from 90° C. to 120° C. and the supplying amount of the organic solvent is not more than 2 times by weight of that of the cycloalkanone.
