FIELD: chemistry of aromatic compounds, petroleum chemistry, chemical technology. ^ SUBSTANCE: method involves carrying out three-stage isolation of aromatic hydrocarbons by separation, absorption and separation using at absorption stage atmosphere distillate off (TS 38.401194-92) as absorbent and prepared in manufacturing oil-polymeric resin by catalytic method. Invention provides reducing loss of aromatic hydrocarbons and improving economic indices of process in manufacturing styrene. ^ EFFECT: improved method for isolation. ^ 1 tbl, 2 dwg, 5 ex
