The catalytic cracking of m-diisopropylbenzene, which is produced as a byproduct of the phenol production process, was studied over various microporous zeolite catalysts. The zeolites had different acidity and pore structures. The highest conversion of m-diisopropylbenzene in catalytic cracking was achieved on the MWW zeolite catalyst. BEA and FAU zeolite catalysts also showed considerably high conversion. The MWW zeolite exhibited a high selectivity for benzene and cumene compared to the other zeolites. The conversion of m-diisopropylbenzene on a MWW zeolite catalyst exceeded 90% at 400 °C. The yield of cumene plus benzene was approximately70% in catalytic cracking over MWW zeolite. The deactivation of MWW zeolite catalysts by carbon deposition on the catalyst could be neglected at high reaction temperatures, whereas it was quite serious on the zeolite catalysts with the MOR structure. Benzene might be produced by a secondary reaction of intermediates in the large pore channels during the retention time.

的催化裂解米-diisopropylbenzene，其被产生作为苯酚生产过程的副产物，进行了研究在各种微孔沸石催化剂。沸石具有不同的酸度和孔结构。的最高转换米-diisopropylbenzene在催化裂化对所MWW沸石催化剂实现的。BEA和FAU沸石催化剂也显示出相当高的转化率。与其他沸石相比，MWW沸石对苯和枯烯具有高选择性。m的转换MWW沸石催化剂上的-二异丙基苯在400℃下超过90％。在MWW沸石上催化裂化中，枯烯加苯的产率约为70％。在高反应温度下，可以忽略掉碳沉积在催化剂上引起的MWW沸石催化剂的失活，而在具有MOR结构的沸石催化剂上，这是相当严重的。在保留时间内，大孔道中中间体的二次反应可能会生成苯。
