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.

摘要: A method for sulfonating olefins comprising the steps of mixing (A) internal olefins having 8 to 22 carbon atoms with (B) alpha-olefins having an average carbon atom number, larger by 3 to 7 than that of the internal olefins (A) in a weight ratio of (A)/(B)=95/5 to 5/95, and sulfonating the resultant mixture with a sulfonating agent. Thus, internal olefins can be sulfonated at a high conversion.
