FIELD: chemistry.
SUBSTANCE: this invention relates to the catalyst used for alkylation of aromatic compounds by monoolefinic aromatic compounds, in particular to the catalyst used for the selective hydrogenization of diolefin and acetylene into olefins; this method describes the catalyst for the selective hydrogenization of diolefin and acetylene containing nondense medium containing gamma-aluminum oxide or theta-aluminum oxide with the volume of micropores less than 10% of the volume of the pores and the specific service 150 m2/g and the palladium on the medium in the amount of 50 - 5000 ppm.
EFFECT: catalyst has the minimal resistance to diffusion through the large pores and minimizes hydrogenization of olefines into paraffins.
