| Abstract: | Solid superacid catalyst (SO 2- 4/ZrO 2) was first used in the synthesis of methyl glycolate with hydroxyacetic acid and methanol. Optimum esterification condition was obtained as follows: the ratio of SO 2- 4/ZrO 2 to hydroxyacetic acid 1 g/mol, reaction time 6 h, the molar ratio of methanol to hydroxyacetic acid 4∶1, and the yield of methyl glycolate could reach 85.7%. The experiment showed that SO 2- 4/ZrO 2 was suitable catalyst for methyl glycolate synthesis by eight times life test. |
