Using a dynamic method, the solubilities of naphthalene in acetone, toluene, xylene, ethanol, heptane, and I-butanol have been determined experimentally from (297.17 to 322.70, 291.35 to 334.65, 299.42 to 337.97, 304.26 to 339.76, 290.25 to 333.75, and 313.77 to 342.8) K, respectively. The experimental data were correlated with the Wilson model, Apelblat equation, and lambda-h model. The calculated results show that the correlation of the Wilson model for six measured systems has less deviation than that of the Apelblat equation and the lambda-h model.
