Effect of Different Aromatic Carboxylic Acid Ligands on the Catalytic Activities of Metal-Organic Frameworks
Abstract:
Metal-organic frameworks based on Zn2+ and different aromatic carboxylic acid ligands were prepared and characterized by X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. They were then used as the catalysts for the transesterification between diphenyl carbonate (DPC) and 1, 4-butyldiol (1, 4-BD) to polycarbonate diol (PCDL). Their catalytic activities in the transesterification process were evaluated by the yield of phenol, and their catalytic activities in the polycondensation process were determined by the number-average molecular weight (Mn) and the hydroxyl value.
