PRODUCTION OF ARALKYLBENZENE

摘要

PURPOSE:To provide the title production method small in the amounts of alkylbenzenesulfonic acids as by-products. CONSTITUTION:The objective aralkylbenzene can be obtained by addition reaction of (A) benzene and/or an alkylbenzene with (B) an aromatic vinyl hydrocarbon compound at 40-90 deg.C in the presence of a catalyst produced from (1) 12-25wt.% of sulfuric acid, (2) 60-80wt.% of an alkylbenzenesulfonic acid and (3) 5-15wt.% of water.
