Abstract
An organic frame material having isopoly-molybdic acid metal for manufacturing polylactic acid and method of manufacturing the same is provided. The chemical formula of the organic frame material having isopoly-molybdic acid metal is [Cu(tfbtb)(β-MoO)0.5(HO)]. tfbtb is a 2,3,5,6-tetrafluoro-bis(1,2,4-triazole-1-methyl) benzene ligand, and [β-MoO] is a β type octamolybdate anion. Sodium molybdate dihydrate, copper salt and organic ligand 2,3,5,6-tetrafluoro-bis (1,2,4-triazole-1-methyl) benzene undergo hydrothermal reaction in a closed condition to form the organic frame material having copper containing isopoly-molybdic acid metal that has a three-dimensional structure. The synthesis method is simple with high yield and reproducibility. The organic frame material having isopoly-molybdic acid metal shows high catalytic activity towards the ring-opening polymerization of lactide. The resulting polylactic acid has a weight average molecular weight exceeding 60,000. The polylactic acid has great potential in the fields of packaging materials and medical high polymer materials.
