| Abstract: | This paper investigated the esterification of glycolic acid to produce methyl glycolate in the presence of strong acidic ion-exchange resin as catalyst.A series of factors,including temperature,alcohol-acid mole ratio,catalyst loading,and stirring,were employed to study their influences on the conversion rate and the reaction rate of glycolic acid.The results show that the conversion rate of glycolic acid could reach as high as 93% under the optimal conditions of reaction temperature 100 ℃,alcohol-acid mole ratio 8∶1,catalyst loading 5% (based on weight),and stirring. |
