| 摘 要： | 将TS-1/H2O2催化体系用于催化香茅醛氨肟化制备香茅醛肟反应中,结果表明,在优化的反应条件下,香茅醛转化率和香茅醛肟选择性分别达99.9%和99.2%以上.反应过程中主要存在两对竞争反应:TS-1催化的醛肟化反应和碱催化的羟醛缩合反应;TS-1催化的醛肟化反应和双键环氧反应.通过调节体系中氨含量可有效抑制副反应.

| Abstract: | The TS-1/H2O2 system has excellent catalytic performance in citronellal ammoximation to citronellal oxime.The effects of various reaction parameters on the catalytic properties of TS-1 were studied in detail.Under the optimized reaction conditions,citronellal conversion and citronellal oxime selectivity are over 99.9% and 99.2%,respectively.We found that there is also aldol condensation,which is competitive with ammoximation.Moreover,the epoxidation and ammoximation of citronellal catalyzed by TS-1 are also competitive reactions.The side reactions can be restrained efficiently by adjusting NH3 amount in reaction system. |
