  摘要：

  芳香化合物，如苯或联苯，与具有一至八个碳原子的烷基化剂（如丙烯）在酸性莫来石沸石催化剂的存在下烷基化，在足以产生富含线性烷基化异构体的取代芳香化合物混合物的条件下进行，例如对二异丙基苯或对，对' 二（异丙基）联苯。这种新型酸性莫来石催化剂的特征在于其硅铝摩尔比、孔隙度和对称指数。芳香化合物的对，对' 二取代异构体在制备热致液晶聚合物的单体中是有用的。

  Polycyclic aromatic compounds, such as biphenyl, are alkylated with an alkylating agent, such as propylene, in the presence of an acidic mordenite zeolite catalyst under conditions sufficient to produce a mixture of substituted polycyclic aromatic compounds enriched in the para alkylated isomers, such as p,p'-di(isopropyl)biphenyl. The novel acidic mordenite catalyst is characterized by its silica/alumina molar ratio, its porosity, and a Symmetry Index. The p,p'-disubstituted isomers of polycyclic aromatic compounds are useful as monomers in the preparation of thermotropic, liquid crystal polymers.

  Aromatic compounds, such as benzene or biphenyl, are alkylated with an alkylating agent, such as propylene, in the presence of an acidic mordenite zeolite catalyst under conditions sufficient to produce a mixture of substituted polycyclic aromatic compounds enriched in the para alkylated isomers, such as p-­diisopropyl-benzene or p,p′-di(isopropyl)biphenyl, respectively. The novel acidic mordenite catalyst is characterized by its silica/alumina molar ratio, its porosity, and Symmetry Index. The p,p′-disubstituted isomers of aromatic compounds are useful as monomers in the preparation of thermotropic, liquid crystal polymers.
