【Abstract】 This paper concerned in the synthesizing of glycolic acid esters with alcohol. and glycolic acid by solid super acid TiO 2/SO 4 2- as catalysts. The specifications of the appropriate condition were obtained from the experiments. When the acid/alcohol mole ratio was 0.07∶0.140; catalyst 1.5 g and the reaction time 4hrs, the yield of propyl Hydrosyacetate could amount to 86.5%. The other glycolic acid esters were also synthesized by using TiO 2/SO 4 2- as catalyst.更多还原
