Thermodynamic parameters of 5-(nitrophenyl)-furan-2-carboxylic acids solutions in propan-2-ol

Abstract

Based on the temperature dependence of the solubility of 5-(2-nitrophenyl)-furan-2-carboxylic acid, 5-(3-nitrophenyl)-furan-2-carboxylic acid and 5-(4-nitrophenyl)-furan-2-carboxylic acid in propan-2-ol, the enthalpy and entropy of their dissolution were calculated. Taking into account the enthalpy and entropy of melting recalculated to 298 K, the enthalpies and entropies of mixing were calculated. The dependence of the solubility of carboxyl-containing substances at 298 K on their melting point was determined.
