ABSTRACT:
Cyclic sulfonate-sulfate anhydrides are produced by the reaction of an .alpha.- or .beta.-type sulfolene compound with SO.sub.3. Reaction of the cyclic sulfonate-sulfate anhydrides with alcohols produces alkyl esters of hydroxysulfolane sulfonic acids. The cyclic sulfonate-sulfate anhydrides or the alkyl esters of hydroxysulfolane sulfonic acids can be hydrolyzed to hydroxysulfolane sulfonic acids or their respective salts. The latter can be acylated to alkylcarbonyloxysulfolane sulfonic acids.
