A sodium-free method was developed for the preparation of highly active aluminosilicate catalysts, in the presence of which alkylation gives up to 14-16 wt. % yields of isopropylbenzene. The catalysts can be used for prolonged periods before regeneration without loss of the initial high activity. Study of the activity of catalysts with various compositions made it possible to establish that the aluminosilicate containing 20 wt. % of Al/sub 2/O/sub 3/ had highest activity in alkylation. Transalkylation of benzene by polyisopropylbenzenes takes place effectively in the presence of the sodium-free aluminosilicate catalyst with 97-98 wt. % conversion of the triisopropylbenzene and diisopropylbenzene.
