Using polyethylene glycol as modifying agent ,the process of reducing the content of benzo [ a] pyrene in coal tar pitch under solvent condition is studied .The study shows that when the reac-tion solvent ratio is 2∶1 in volume between cyclohexane and toluene ,the sulfuric acid and polyethy-lene glycol 600 used are 6.67%and 10%in weight of the coal tar pitch respectively ,and the reac-tion takes place under the temperature of 80℃ for 5h, benzo [ a] pyrene can be removed up to 85 .59%.
