The authors investigated the gas-liquid phase alkylation reaction of benzene with propylene in the presence of aluminosilicate catalysts which have been activated by treatment with varying amounts of the complex derived from aluminum chloride and polyalkylbenzene, and also studied the viability of various compounds as complex promoters. It was established that catalyst activity is enhanced by modification with the complex. The optimum concentration of complex (in the modified catalyst) is 15. wt. %. It was also established that isobutyl chloride added to the reaction mixture in the presence of the modified catalyst acts as a promoter and increases the activity of the catalyst twofold, to an acceptable level. The value of the energy of activation of the alkylation reaction was determined by kinetic analysis of the experimental data to be 38,300 J/mole.
