ABSTRACT:
A process for sulfonating internal olefins wherein a dilute solution of the internal olefins in an inert hydrocarbon solvent is sulfonated to produce a reaction mixture containing intermediate sulfonated compounds, the intermediate sulfonated compounds in the reaction mixture being neutralized under conditions to form neutralized sulfonated compounds, the neutralized sulfonated compounds in the reaction mixture being hydrolyzed to form a product mixture containing hydroxy alkane sulfonates and alkene sulfonates that are then recovered.
