FIELD: chemistry.
SUBSTANCE: one of the versions involves: (a) feeding alkylation raw material containing benzene and propylene into an alkylation reaction zone (100), having at least one alkylation catalyst layer containing zeolite UZM-8, having molar ratio Si/Al2 in the frame of 24-35, and (b) removing an alkylation product (10) containing cumene from the alkylation reaction zone (100) of the raw material. Propylene in the alkylation raw material is converted in the alkylation reaction zone (100) to cumene with selectivity of at least 85%.
EFFECT: improved selectivity with respect to cumene.
