FIELD: chemistry.
SUBSTANCE: invention refers to the way of selective hydrogenation of diolefines and ethines that includes contacting of the olefinic flow containing along with olefines diolefines and ethines with the selective hydrogenation accelerant that contains a low-density bearer the density of which is lower than 0.5 g/cm with the micropores volume of no more than 10 % of the volume of the accelerant pores and with the specific surface area from more than 50 m²/g to 150 m²/g; the micropores are characterized by the pore diameter that does not exceed 100 Å, and more than half of the accelerant pore volume is comprised by the pores that have a diameter of at least 1,000 Å.
EFFECT: production of slightly branched alkyl benzenes.
