Abstract
A method for aralkylation of benzene or alkylbenzenes which is characterized in that an aromatic olefin having a double bond or double bonds which are conjugated with the benzene ring is added to the benzene or alkylbenzenes in the presence of at least one member of catalyst selected from the group consisting of the compounds represented by the general formula: C.sub.n F.sub.2n+1-m Cl.sub.m SO.sub.3 H in which the symbol n is an integer from 1 to 5 and m is 0 or 1. Since the selectivity to the aromatic olefin in the reaction is excellent, the mixture of aromatic olefins and aliphatic olefins can be employed as one of the starting material.
Claims10
In a method of aralkylation of at least one member selected from the group consisting of benzene and alkylbenzenes each having an alkyl group or groups of 1 to 18 in total carbon atom number by reacting at least one aromatic olefin each having a double bond or double bonds which are conjugated with the benzene ring thereof with said at least one member, the improvement in said method comprising carrying out said aralkylation in the presence of at least one catalyst selected from the group of compounds represented by the general formula:
- C.sub.n F.sub.2n+1-m Cl.sub.m SO.sub.3 H,
- in which the symbol n is an integer from 1 to 5, inclusive, and m is 0 (zero) or 1.
