• Phenylphosphonic acid
• Solubility
• Thermodynamic models
• Modified Apelblat equation

In this study, the solubility of phenylphosphonic acid in n-propanol, acetone, acetonitrile, ethyl acetate, and chloroform was determined by the static analytical method over the temperature range from 288.15 to 318.15 K. At a given temperature, the order of solubility is n-propanol > acetone > acetonitrile > ethyl acetate > chloroform. The modified Apelblat equation and lambda h model were used to represent the experimental data with satisfactory correlation results. Moreover, the enthalpy, entropy, and Gibbs free energy of solution of phenylphosphonic acid in the selected organic solvents were calculated from the measured solubility data by the modified van't Hoff equation.
