The replacement of homogeneous catalysts by heterogeneous catalysts is very important in practical productions of fine chemicals from the standpoint of the so-called "zero-emission" or "green chemistry". In the present study we find some Al-introduced mesoporous molecular sieves "MCM-41" catalysts show very high activities for Diels-Alder and Friedel-Crafts reactions. We also find the manner of Al-introduction is very important, because the total amounts of acid sites and the ratio of Bronsted/Lewis acid sites are influenced by the manner of the Al-introduction. The activity per Al-atom of Al-introduced MCM-41 catalyst with the highest activity for Diels-Alder and Friedel-Crafts reactions is almost the same as that of homogeneous AlCl_3 catalyst.

从“零排放”或“绿色化学”的角度来看，用非均相催化剂取代均相催化剂在精细化学品生产中具有重要意义。在本研究中，我们发现一些铝引入的介孔分子筛“MCM-41”催化剂显示出很高的Diels-Alder和Friedel-Crafts反应活性。我们还发现铝的引入方式是非常重要的，因为铝的引入方式影响酸中心的总量和Bronsted/刘易斯酸中心的比例。对Diels-Alder反应和Friedel-Crafts反应活性最高的MCM-41催化剂，其单铝活性与均相AlCl_3催化剂相当。
