| titleOfInvention | Zinc coordination polymer catalyst for preparing polyglycolic acid and preparation method thereof |
| abstract | The invention relates to a zinc coordination polymer catalyst for preparing polyglycolic acid and a preparation method thereof, and relates to the field of polyglycolic acid catalysts. The chemical formula is [ Zn (BDC) L ], wherein BDC is terephthalate anion, and L is 2,3,5, 6-tetrachloro-N, N' -di (4-pyridine) diamide ligand. The invention adopts zinc nitrate hexahydrate, organic ligand terephthalic acid and 2,3,5, 6-tetrachloro-N, N' -di (4-pyridine) diamide to prepare the zinc coordination polymer containing the quadruple interpenetrating diamond three-dimensional network structure in N, N-dimethylformamide through thermal reaction under a closed condition. The synthesis method disclosed by the invention has high yield and good reproducibility; the obtained crystal has high purity. The zinc coordination polymer has good catalytic activity for catalyzing the ring-opening polymerization of glycolide, and the prepared polyglycolic acid has the weight-average molecular weight of more than 6 ten thousand, and can be applied to the field of medical high polymer materials. |
