| titleOfInvention | The oximation method of ketones |
| abstract | The invention discloses a method for oximation of ketones. In order to improve the reaction efficiency and selectivity of oximation, compared with the traditional amidoximation process, the invention firstly adopts a reactive distillation process, and in the presence of a novel magnetically loaded modified titanium-silicon molecular sieve Under the following conditions, hydrogen peroxide and ammonia react to generate hydroxylamine, which is concentrated by rectification to obtain a higher concentration of hydroxylamine aqueous solution, which undergoes oximation reaction with ketone to obtain ketoxime. Under the process conditions, the ketone and hydroxylamine adopt a continuous oximation process, and because the concentration of hydroxylamine is increased, the efficiency is significantly improved, and the removal of ammonia also makes the ketoxime selectivity as high as 99.8%. |
