ABSTRACT:
This invention relates to an improved catalytic process for the alkylation of benzene or substituted benzene with alkyl halides for the continuous production of diarylalkanes or substituted derivatives thereof using ethylaluminum dichloride or methylaluminum dichloride as an organoaluminum dichloride catalyst. A process and apparatus are provided for reacting either benzene (or a substituted benzene compound) together with either an alkyl halide or an aromatic halide.
