Method for producing tetramethyl glycolide |
| abstract |
The object of the present invention is to provide a process for the production of cyclic esters, which is particularly simple, inexpensive and can be carried out in high yields. A special problem was in particular to create a method that can be used flexibly for the production of different products, thus ensuring a high performance utilization of the production plant used. In producing tetramethyl glycolide, a composition comprising at least 50% by mass of 2-hydroxyisobutyric acid and / or tetramethyl glycolide is heated to a temperature of at least 100 ° C. It is solved by the production method of methyl glycolide. [Selection figure] None |
