The reaction of styrene with α-methylstyrene has been studied over Y, Beta and ZSM-12 zeolites at 80–120 °C in the presence or absence of chlorobenzene. Homo- and codimers of styrene and α-methylstyrene were the main reaction products. The yield of dimers and their structure depends on zeolite type and the experimental conditions. Dimers were formed with greater selectively over zeolite HZSM-12 (S = 80–83%)
在存在或不存在氯苯的情况下,已在80-120°C的Y,Beta和ZSM-12沸石上研究了苯乙烯与α-甲基苯乙烯的反应。苯乙烯和α-甲基苯乙烯的均聚物和共聚单体是主要的反应产物。二聚体的产率及其结构取决于沸石类型和实验条件。形成的二聚体比HZSM-12沸石具有更高的选择性(S = 80–83%),其结构特征促进了线性化合物的合成。在HY和HBeta沸石的存在下,环状均聚和共聚二聚体是主要产物。随着反应温度和催化剂浓度的增加以及在溶剂的存在下,二聚体的产率增加。所有研究的沸石在120°C下均表现出对苯乙烯和α-甲基苯乙烯的高共聚活性。
