| titleOfInvention | Purification of glycolide |
| abstract | A process for the purification of glycolide which comprises dissolving the glycolide to be purified in a suitable organic solvent, adding alumina to the resulting solution to form a slurry wherein the alumina is in intimate contact with the dissolved glycolide, stirring the slurry under controlled conditions for a period of 1 to 60 minutes, and filtering to remove the alumina and, if desired, evaporating to remove the solvent and recovering the purified glycolide; and the production of suture-grade polyglycolic acid by the polymerization of the resulting purified glycolide. |
