ABSTRACT:
p-Chloroalkylbenzene is selectively produced by chlorinating an alkylbenzene in the presence of a phenoxthine compound having the formula ##STR1## wherein X.sub.1, X.sub.2, X.sub.3 and X.sub.4 are the same or different and respectively represent hydrogen atom; an electron attractive group or an electron donative group and a Lewis acid or its precursor as a catalyst.
The process for producing a p-chloroalkylbenzene can be repeatedly carried out by separating the resulting a p-chloroalkylbenzene and adding a hydrogen halide to the residual mixture containing the catalyst to activate the catalyst and chlorinating a newly added alkylbenzene.
