以用四丙基溴化铵（ＴＰＡＢｒ）为模板剂合成的钛硅分子筛ＴＳ－１为催化剂，Ｈ２Ｏ２为氧化剂，系统地研究了丙烯环氧化反应的规律．考察了反应温度、丙烯压力、催化剂用量、反应时间等反应参数的影响，找到了较佳的丙烯环氧化反应条件．研究发现：温度对反应结果有显著影响，随反应温度升高，Ｈ２Ｏ２转化率提高，但环氧丙烷（ＰＯ）选择性降低；丙烯压力对反应结果无明显影响；催化剂不经再生处理，多次重复使用，产物分布保持不变，Ｈ２Ｏ２转化率略有下降；少量水的存在对丙烯环氧化反应影响不大，但若以水代替甲醇为溶剂，反应速率降低，且产物中出现大量丙二醇；以叔丁基过氧化氢代替Ｈ２Ｏ２为氧化剂时，ＴＳ－１不具有催化活性．
Using the titanium silicalite TS-1 synthesized by using tetrapropylammonium bromide (TPABr) as the template and the H2O2 as the oxidant, the law of epoxidation of propylene was studied systematically. The effects of reaction temperature, pressure of propylene, amount of catalyst, reaction time and other reaction parameters were investigated. The optimum epoxidation conditions of propylene were found out. The results showed that the temperature had a significant effect on the reaction results. With the increase of reaction temperature, the conversion of H2O2 increased, but the selectivity of propylene oxide (PO) decreased. The propylene pressure had no significant effect on the reaction results. However, if water is used instead of methanol as solvent, the reaction rate will decrease and a large amount of propylene glycol will appear in the product. When t-butyl hydroperoxide was used instead of H2O2 as oxidant, TS-1 did not have catalytic activity.
