    摘要: Alkylbenzene is sulfonated in a thin film type sulfonation process by adding 2 through 20 parts by weight, based on 100 parts by weight of said alkylbenzene, of alkylbenzene sulfonic acids having alkyl groups of 1 through 20 carbon atoms and/or benzene sulfonic acids to the alkylbenzene prior to the contact thereof with diluted gaseous sulfur trioxide. The addition of alkylbenzene sulfonic acids and/or benzenesulfonic acid effectively prevents the formation of adherent deposits on the surface of a reaction wall.
