ABSTRACT

The solubilities of 1-naphthaleneacetic acid (NAA) have been measured by the synthetic method in 10 pure organic solvents including methanol, ethanol, 2-propanol, toluene, acetone, acetonitrile, 1,4-dioxane, 1,2-dichloroethane, ethyl acetate, and tetrahydrofuran and binary methanol + water mixtures from (278.25 to 323.55) K under atmospheric pressure. The modified Apelblat equation, h equation, and Wilson equation were employed to correlate the solubility data. Furthermore, the solubility of NAA in a binary solvent mixture was regressed with a combined nearly ideal binary solvent/Redlich Kister (CNIBS/R K) equation and the hybrid equation. According to the calculations based on these equations, the modified Apelblat equation gave the best correlation results with the experimental data in all selected solvents.
