Furandicarboxylates: marine biomass-derived bioplasticizers
이경원,( Nguyen Tan Phat ),박석규,문다솜,조진구 한국공업화학회 2017 한국공업화학회 연구논문 초록집 Vol.2017 No.1
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.

2,5 Furandicarboxylic acid (FDCA) is considered one of the top 12 building block compounds derived from biomass that can lead to a sustainable development of a new chemical platform. FDCA has a potential as the replacement for terephthalic, isophthalic, and adipic acid, which are widely used components in the polymer industry. In this research, we focused on the homogeneous oxidation of 5-Hydroxymethyl-2-furaldehyde (HMF) using N-Hydroxyphthalimide (NHPI) or N-Hydroxysuccinimide (NHSI) together with metal co-catalyst. The desired product, FDCA, is achieved through 3 steps of oxidation as shown in the scheme below. Several metal co-catalysts and solvents were screened and optimized for the reaction. Results show that partial oxidation was achieved and the major product was 2,5-Furandicarboxaldehyde (DFF). New experimental conditions are being tested to further push the oxidation of DFF in order to achieve higher selectivity of FDCA.
