MANUFACTURE OF CYCLOHEXANONE OXIME

摘要

PROBLEM TO BE SOLVED: To provide a method economically manufacturing cyclohexanone oxime by carrying out a reaction of cyclohexanone with hydrogen peroxide and ammonia. SOLUTION: In the process manufacturing cyclohexanone oxime by oxidizing cyclohexanone with hydrogen peroxide and ammonia under the presence of a titanosilicate catalyst, the hydrogen peroxide directly obtained by extracting process in the alkylanthraquinone method without distillation and purification and including stabilizer of <=150 ppm (based on 100% hydrogen peroxide), is used.
