FIELD: petroleum chemistry, organic chemistry, chemical technology.
SUBSTANCE: method involves carrying out the interaction condensed and polynuclear aromatic hydrocarbons, in particular, naphthalene and biphenyl with polyalkylaromatic hydrocarbons, in particular, with diisopropyl benzene under transalkylation conditions with aim to prepare dialkylated condensed and polynuclear aromatic hydrocarbons. Transalkylation reaction is carried out in the presence of zeolite catalysts comprising 12-membered oxygen rings with diameter of zeolite channels from 5.6 to 7.7 
. Invention provides the development of new method for preparing dialkylated polycyclic hydrocarbons.
EFFECT: improved preparing method.
