The selectivity of the catalyst has been varied by changing the reaction condition. The SHTC shows one of the best selectivity for the formation of monoacetins without using excess glycerol. It was found that the catalyst gets deactivated after recycling due to the generation of sulfonated ester on the catalyst surface. The recycled catalyst was again activated by acid treatment with subsequent hydrolysis of sulfonated esters. The catalyst has excellent potential for various bio-refinery processes [28].
