ABSTRACT:
The present invention provides a process for aralkylation of alkylbenzenes wherein an alkylbenzene or alkylbenzenes containing in the substituent alkyl group or groups from 1 to 4 carbon atoms in total is aralkylated with at least one styrene selected from the group consisting of styrene, vinyltoluenes and .alpha.-methylstyrene which comprises carrying out the reaction by continuously feeding to a catalyst layer the above-mentioned alkylbenzene or alkylbenzenes and styrene sources in liquid phase at a temperature from 100.degree. C. to 200.degree. C., said catalyst layer being filled with synthetic silica-alumina containing from 20% by weight to 50% by weight alumina that has been calcined at a temperature in the range from 450.degree. C. to 600.degree. C.
