提出了将原位合成的F -ZSM - 5沸石分子筛用于偏三甲苯 -甲醇烷基化的催化反应的新方法。实验表明 ,F离子的原位引入 ,提高了ZSM - 5沸石催化剂的催化活性 ,使偏三甲苯转化率达 5 6%以上 ,均四甲苯在四甲苯中的含量达 98%以上。
A new method was proposed for the catalytic reaction of F-ZSM-5 zeolite synthesized in situ for the alkylation of p-trimethylbenzene with methanol. The experimental results showed that the introduction of F - ion in situ enhanced the catalytic activity of ZSM - 5 zeolite catalyst, the conversion of p - trimethylbenzene was above 56%, and the content of.
