The Synthesis of Oleic Acid Polyglycol Ester Catalyzed by Solid Super Acid

摘要

A SO_4~(2-)/ZrO2 super acid was prepared and the effect of different kinds of catalysts on the esterification reaction reviewed. The results showed that the SO_4~(2-)/ZrO2 super acid had higher catalytic activity and reactive selectivity in the synthesis of oleic acid polyglycol ester. Under optimum conditions the product was a monoester and the rate of production was more than 90%. The reaction product was characterized.
