| titleOfInvention | Continuous preparation method of glycolide |
| abstract | The present invention relates to a continuous method for preparing glycolide, and more particularly, after the glycolic acid and the catalyst which have undergone dehydration in the dehydration reactor are introduced into the polymerization reactor through different inlets, the low molecular weight glycolic acid oligomer is polymerized. The present invention relates to a method for continuously producing glycolide having high production yield and uniform physical properties by continuously introducing the resulting oligomer into a screw type pyrolysis tube. |
