Summary:PURPOSE:An alkane or alkene is added to separate unreacting olefin from the reaction mixture resulting from sulfonation of an olefin, neutralization and hydrolysis whereby the titled compound which is used as an active ingredient in detergents is obtained in high efficiency at low temperature. CONSTITUTION:An olefin of 10-30C is sulfonated, neutralized and hydrolyzed and unreacting olefin is separated from the reaction mixture where an alkane or alkene of 8-27C less than that of the sulfonated olefin is added in an amount of 5-200pts.wt., per 100pts.wt. of the olefinsulfonate salt to effect separation into the aqueous phase containing the sulfonate salt and the oil phase containing the unreacting olefin. Since this process permits low conversion of sulfonation, it can be applied to the sulfonation of an inner olefin of low reactivity advantageously.
