| 摘 要： | 研究了加料方式和底物浓度对钛硅分子筛Ti-MWW催化环己酮液相氨肟化反应的影响. 结果表明,加料方式对 Ti-MWW 催化环己酮氨肟化过程有重要影响,过氧化氢的浓度对反应过程也有一定的影响. 在过氧化氢缓慢加入反应体系的情况下,环己酮转化率和环己酮肟选择性都高于99%, 而且该反应过程以水作溶剂,对环境友好.

| Abstract: | The liquid-phase ammoximation of cyclohexanone with ammonia and hydrogen peroxide was conducted over the Ti-MWW catalyst. The operating conditions of the reaction, especially the feeding mode of H_2O_2 greatly affected the catalytic performance of Ti-MWW. In addition, the concentration of H_2O_2 also affected the ammoximation reaction. Under the optimum reaction conditions, the cyclohexanone conversion and oxime selectivity were both over 99%. |
