环戊二烯甲基化反应中催化剂的研究
Study on Catalyst Used for Methylation of Cyclopentadiene
【摘要】 在环戊二烯与甲醇催化甲基化制备甲基环戊二烯反应中,对不同催化剂的催化活性进行考察,初步探索催化剂酸碱中心强度对反应的影响.并由此筛选出对甲基环戊二烯合成有利的催化剂.结果表明:催化剂的酸碱中心强度相当的催化剂在此反应中活性较高;由γAl2O3 与K2CO3 混合制备的催化剂具有较高的催化活性.环戊二烯单程转化率高于25 % ,甲基环戊二烯选择性在98 % 以上.
【Abstract】 The activity of some catalysts for preparation of methylcyclopentadiene through fixed bed was studied. In the reaction, methanol is used as methylation reagent. The influence of strength of acidic and basic center in catalysts on the reaction was discussed. It was shown that the catalyst whose acidic and basic center strength is well\|matched will be active for the reaction. The catalyst prepared by γ\|Al\-2O\-3 and K\-2CO\-3 was suitable for the reaction.
