| titleOfInvention | A kind of method and its cracker prepared by glycolide |
| abstract | The invention discloses new methods prepared by a kind of glycolide, and in this method, the polycondensation of glycolic takes the mode for the dehydration that heats up stage by stage, and polyglycolic acid then is ground into powder with lifting stirring means in batch condensation polymerization reactor；Devise a kind of novel polyglycolic acid cracking still, pass through an elliptical spiral agitating device inside cracking still, when polyglycolic acid, which heats, to be cracked, polyglycolic acid melt upper and lower, vertical and horizontal direction in cracking still stirs, effectively disperseed, it is carbonized caused by avoiding the accumulation of polyglycolic acid, improves the yield of glycolide. |
