在过去的四、五十年里，芳烃与烯烃的烷基化反应在开发环境友好工艺方面取得了巨大的进步。特别是在固体催化剂的研究上投入了大量的精力，以取代传统上用作酸或碱催化烷基化催化剂的矿物酸或Lewis酸和游离碱。在这里，我们回顾了工业上值得注意的用于生产乙苯(EB)、异丙苯、直链烷基苯和伞花烃的苯和甲苯的烷基化选择。我们还讨论了不同沸石的特性作为它们在所考虑的反应中的活性和选择性的函数。(C)2002 Elsevier Science B.V.保留所有权利。
Huge improvements towards the development of environmentally friendly processes have been achieved in the alkylations of aromatics with olefins, since the last four or five decades. Particularly, much efforts have been devoted to the research of solid catalysts adequate to substitute mineral or Lewis acids and free bases traditionally employed as catalysts in the acid or base catalyzed alkylations. Here we review the options industrially worthy of note in the alkylations of benzene and toluene for the production of ethylbenzene (EB), cumene, linear alkyl benzene and cymene. We also discuss features of different zeolites as a function of their activity and selectivity in the reactions considered. (C) 2002 Elsevier Science B.V. All rights reserved.
