【摘要】 本文叙述了通过一系列对比实验,如反应时间、催化剂用量、以及反应温度等对乙烯降冰片烯异构化反应的影响,进一步考察乙烯降冰片烯在Na-Na2CO3/γ-Al2O3型固体超强碱催化剂作用下异构化反应的转化率和选择性。实验表明:最佳反应条件是:时间30min、温度不高于25℃、m(催化剂)∶m(乙烯降冰片烯)=1∶50转化率可达99%以上,选择性接近100%,反应条件温和,并且催化剂可重复使用。更多还原

【Abstract】 In this paper, a series of contrast experiment are introduced, for example reaction time, actalyst capacity and reaction temperature influence on isomerization of vinyl norbornene, the conversion and the selectivity are investigated to go a step further. The results showed that the optimum reaction conditions were as follows: reaction time is 30 min. reaction temperature is not more than 25℃ m(catalyst)∶m(VNB)=1∶50,the conversion of VNB reached above 99% and the selectivity of it approached 100%, and reaction condition is moderation, and catalyst can be reused.更多还原
