| titleOfInvention | A kind of glycolide and its preparation method and application |
| abstract | The invention relates to a preparation method of glycolide, which comprises depolymerization after contacting glycolic acid oligomer with at least one thermally conductive particle. The method solves the technical problem of accumulation of heavy residues in the reaction device during the depolymerization of glycolic acid oligomer melt, and makes the depolymerization reaction device easy to clean when the glycolic acid oligomer batch feeding process is adopted for the depolymerization reaction. , and the depolymerization reaction can be carried out for a long time when the glycolic acid oligomer continuous feeding or continuous batch feeding process is used. |
