Galactaric acid which is a sugar acid derived from marine carbohydrate biomass, was used as starting material for a one-pot reaction in alcoholic medium to produce furandicarboxylic acids (FDCA) ester. A series of products were successfully synthesized, isolated and structurally characterized by spectra. Those products could act as bioplasticizers in polymer matrices with the core being 2,5-FDCA or 2,3-FDCA. This research provides information about the effect of alcohol solvents on the formation of products. Also for the first time, the plasticizing effects of 2,3-furandicarboxylate on poly(vinyl chloride) matrix is unveiled through some methods, namely Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), tensile test on universal testing machine (UTM) and migration analyses. |
