Measurement and modeling of solubility of furan 2-carboxylic acid in mono and binary systems

The solubility of Furan 2-carboxylic acid is determined experimentally in seven mono solvents toluene, hexane, diisopropylether, 1, 2–dichloroethane, acetonitrile, methylisobutylketone, methanol at temperatures ranging from 283.15 K – 333.15 K and five binary systems toluene + hexane, diisopropylether + hexane, 1, 2–dichloroethane + hexane, methylisobutylketone + hexane, ethanol + hexane at 293.15 K – 333.15 K using isothermal saturation method at the atmospheric pressure of 95.5 kPa. The results indicated that Furan 2-carboxylic acid solubility in mono and binary systems increased with increase in temperature at a measurable range and was in the decreasing order of methanol > methylisobutylketone > acetonitrile > 1,2–dichloroethane > diisopropylether > toluene > hexane. The experimental solubility data obtained using mono and binary systems is correlated with Van't Hoff, Modified Apelblat, Buchowski, CNIBS/R-K, Jouyban – Acree, modified Van't Hoff–Jouyban–Acree, modified Apelblat–Jouyban–Acree thermodynamic models. The data is in good harmony with the Modified Apelblat equation for most of the solvent systems and the models CNIBS/R-K method showed least deviation for diisopropylether + hexane system with an RAD 0.65%. •Solubility of furan-2-carboxylic acid is determined in mono and binary solvents.•Correlation of solubility data using modified Apelblat, CNIBS/R-K, JA models.•Solubility of Furan 2-carboxylic acid highest in methanol and least in hexane.•Binary system of in ethanol + hexane showed highest solubility of the solute.
