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.

Process for sulfonating internal olefins

A process for producing alkoxylated mono-, di-, and tri-esters in which a starting material ester and an alkylene oxide are reacted in the presence of selected calcium based catalysts.

Process for alkoxylation of esters and products produced therefrom

A process for producing alkoxylated methyl esters to produce a narrow homolog distribution of the alkoxylate species in which a staring material methyl ester and an alkylene oxide are reacted in the presence of selected calcium based catalysts.
