ABSTRACT

2, 5-furandicarboxylic acid (FDCA) serves as a monomer in various polyesters, and is often obtained through the oxidation of 5-hydroxymethylfurfural. Solubility data of FDCA is of great value for the reaction process analysis and separation technology. Experimental solubility of FDCA in eight pure solvents (water, methanol, acetonitrile, acetic acid, ethyl acetate, methyl isobutyl ketone (MIBK), 1-butanol, and isobutanol) and two binary solvent systems (water + acetonitrile, water + acetic acid) in the temperature range of (313.15 to 363.15) K was determined. In pure solvents and binary mixtures, the solubility of FDCA increased with the increasing of temperature. The order from large to small of solubility in pure solvents was: methanol, 1-butanol, isobutanol , acetic acid, water, MIBK, ethyl acetate, acetonitrile. The mole fraction of FDCA in binary mixtures increased first, then decreased with the increasing of mole fraction of water. The solubility data was correlated with UNIQUAC model, NRTL model and WILSON model.
