摘要
采用无机钛硅原料体系合成出了TS-1分子筛,并对TS-1分子筛催化氯丙烯环氧化反应进行了研究.在以甲醇为溶剂的体系中考察了反应时间、反应温度、催化剂用量、氯丙烯与双氧水的摩尔比对反应的影响,得到了无机钛硅原料体系合成的TS-1催化氯丙烯环氧化反应的最优条件:反应时间为60 min,反应温度为45℃,催化剂用量为22.5 g L-1,氯丙烯与双氧水的摩尔比n(AC):n(H2O2)=1.8,并对无机钛硅原料体系合成的TS-1进行了修饰改性,评价了其催化性能.
The epoxidation of allyl chloride catalyzed by TS-1 synthesized from inorganic titanosilicate system was studied. Reaction time, reaction temperature, amount of catalyst and the ratio of reactants were investigated. The optimum reaction is as follows： reaction time 60min, reaction temperature 45 ℃, amount of catalyst 22.5 g/L, n （AC）： n（ H202） = 1.8. TS-1 was modified by many methods,the catalytic performances were investigated also.
