改性Y分子筛在氧化苯乙烯与乙醇加成反应中的的催化作用

Study on the Catalysis of DUSY on Addiition Reaction of Epoxyethylbenzene and Alcohol

为了解改性Y分子筛(DUSY)作为固体酸催化剂的催化活性,采用气相色谱分析法研究了DUSY在氧化苯乙烯与醇加成反应中的催化作用及反应条件对该加成反应的影响.结果表明,DUSY对该加成反应催化活性较高,得出的最佳反应条件是:反应温度为75℃,反应时间为2h,反应物配比(氧化苯乙烯∶乙酵)为1∶3(摩尔比),1mol氧化苯乙烯催化剂用量为22.8g.

The catalysis of DUSY on addition reaction of epoxyethylbenzene and alcohol is studied by GC method.The effects of the condition on the reaction are tested.The result express the catalytic activity of the DUSY is high.The optimum condit ions are obtained:the reaction temperature is 75 ℃;the reaction time is 2 h;the proportion of thereactantis 1∶3 (mol);theconsumption ofDUSYis 22.8 g on 1 mol epoxyethybenzene.
