The invention provides a method for producing an (alkylphenyl)alkylcyclohexane, including a step of condensing an alkylbenzene with an alkylcyclohexene or an alkylcyclohexanol in the presence of an acid catalyst, and (alkylphenyl)alkylcyclohexane represented by formula (8). The (alkylphenyl)alkylcyclohexane produced through the production method can be transformed into an alkylbiphenyl, a biphenylpolycarboxylic acid, or a biphenylpolycarboxylic anhydride. Through the production method, an (alkylphenyl)alkylcyclohexane and an alkylbiphenyl of interest can be readily and selectively produced.
(wherein R1 represents a C1-C4 alkyl group; R2 represents a C1-C4 alkyl group; m is an integer of 0 to 2; n' is an integer of 2 to 5; other conditions are the same as defined in claim 18.)
本发明提供了一种生产(烷基苯基)烷基环己烷的方法,包括在酸催化剂存在下将烷基苯与烷基环己烯或烷基环己醇缩合的步骤,以及式(8)代表的(烷基苯基)烷基环己烷。通过该生产方法生产的(烷基苯)烷基环己烷可转化为烷基联苯、联苯聚羧酸或联苯聚羧酸酐。通过该生产方法,可以很容易地、有选择地生产出一种(烷基苯)烷基环己烷和一种烷基联苯。
(其中 R1 代表 C1-C4 烷基;R2 代表 C1-C4 烷基;m 为 0 至 2 的整数;n'为 2 至 5 的整数;其他条件与权利要求 18 中定义的相同)。
