FIELD: chemistry.
SUBSTANCE: present invention relates to a method of treating polyalkyl aromatic hydrocarbons. Disclosed method of treating a mixture containing polyalkylated aromatic compounds involves hydrogen reduction of polyaromatic compounds in the presence of a catalyst for hydrogenating oxygen-containing organic substrates. Said polyaromatic compounds are obtained during alkylation of aromatic compounds using an alkylating agent selected from alcohols, primary olefins or mixtures thereof. Amount of aromatic rings which undergoes hydrogenation during reduction with hydrogen is less than 1% relative to all aromatic rings.
EFFECT: proposed in the invention approach increases stability and duration of operation of the trans-alkylation catalyst.
