Neckers等曾经报道可以用苯乙烯-二乙烯基苯共聚物保护的无水三氯化铝做为醇类的缩合、酯化和缩醛化的催化剂.这是关于使用聚合物保护三氯化铝的最早报道. Magnotta等曾使用交联的聚苯乙烯磺酸和三氯化铝合成了所谓“聚合物超酸”,并在85℃,常压下用这种催化剂对正己烷的异构化和裂化进行了研究.这是具有实用意义 Neckers et al. Have reported that anhydrous aluminum trichloride protected with a styrene-divinylbenzene copolymer can be used as a catalyst for the condensation, esterification and acetalization of alcohols.This is related to the use of polymers to protect aluminum trichloride . The earliest reports of Magnotta et al. Used crosslinked polystyrene sulfonic acid and aluminum trichloride to synthesize the so-called “polymeric superacid” and use this catalyst for the isomerization of n-hexane at 85 ° C And cracking has been studied. This is of practical significance
