Abstract

1. Essence of the invention: Method for purification of benzene. 2. Field of use: petrochemical and by-product-coking industry. 3. Substance of invention: raw benzene is treated by an acid agent that represent "acid tar" of processes of treatment of aromatic hydrocarbons by sulfuric acid at the temperature of 40-160 °C, amount of acid agent in terms of sulfonic group is 2-20 per cent by weight. 5. Technical result: in presence of aromatic sulfonic acids within given technological parameters the additives to raw benzene are polymerized, polycondensed and alkylated turning into "tar" products: reaction of sulfonating of benzene is excluded; "tarring" products are easily absorbed by acid tars providing for efficient separation of tar and benzene fractions and improving separation efficiency of raw benzene. 1 claim, 5 tables.
