Development of Shape - selective Alkylation of Biphenyl to 4,4' - Dialkylbiphenyl

综述了用沸石分子筛作催化剂,择形烷基化合成4,4’-二烷基联苯的研究进展。重点介绍了近年来对两种催化刑HM和HZSM-5的改性研究,催化烷基化反应合成4,4’-二异丙基联苯和4,4’-二甲基联苯所取得的研究成果。明确了今后择形烷基化合成4,4’-二烷基联苯的研究方向。

The development of shape - selective alkylation of biphenyl to 4,4' - dialkylbiphenyl over zeolite catalysts is reviewed. The research achievement of the shape - selective alkylation over modified HM and HZSM - 5 catalysts are described. And the direction of research in future is suggested.
