Using a dynamic method, the Solubilities of 3-pentadecylphenol in ethanol, 1-butanol, toluene, acetone, tetrachloromethane, and ethyl acetate have been determined experimentally from (291.47 to 3 12.87, 293.55 to 312.36, 295.25 to 317.38, 289.08 to 311.77, 288.46 to 312.23, and 290.83 to 313.35) K, respectively. The results are correlated with the lambda h equation, the Apelblat equation, and the Wilson equation. The calculated results show that the correlation of the Apelblat equation for six measured systems has less deviation than that of the lambda h equation and the Wilson model.
