Abstract (en)

[origin: WO0064867A1] A product for producing and recovering sulfonated internal olefins wherein an internal olefin is sulfonated to produce a reaction mixture containing intermediate sulfonated compounds, the reaction mixture is neutralized and hydrolyzed to form a product mixture containing hydroxyalkane sulfonates, alkene sulfonates, and hydrocarbon oil, and the product mixture is subjected to azeotropic distillation to effect separation of the hydrocarbon oil from the product mixture.
