Method for producing tetramethyl glycolide |
| abstract |
(57) [Problem] To provide a method for economically producing high-purity tetramethyl glycolide from α-hydroxyisobutyric acid ester with high efficiency and high yield. SOLUTION: Water is added to α-hydroxyisobutyric acid ester, and a part or all of α-hydroxyisobutyric acid ester is hydrolyzed to produce α-hydroxyisobutyric acid using a substance acting as an acid as a catalyst to obtain α-hydroxyisobutyric acid. From the obtained α-hydroxyisobutyric acid, tetramethyl glycolide is formed while continuously removing water in the presence of a solvent which is substantially immiscible with water. |
