Using a dynamic method, the solubilities of 1,4-naphthoquinone in acetone, toluene, xylene, ethanol, and n-butyl alcohol have been determined experimentally from (293.27 to 319.63, 294.10 to 331.95, 289.63 to 323.07, 279.80 to 335.43, and 295.44 to 355.07) 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 Apelblat equation and lambda-h model for five measured systems has less deviation than that of the Wilson model.
