The solubilities of naphthalene in decalin, octane, dodecane, dichloromethane, trichloromethane, carbon tetrachloride, 1,2-dichloroethane, o-dichlorobenzene, 1-octanol, 2-octanone, 4-methyl-2-pentanone, and benzene were measured by a dynamic method over the temperature range of 279 to 330 K at atmospheric pressure. By comparison, the experimental results indicated that the molality solubility in dichloromethane reached maximum at certain temperature. Then, the Apelblat equation, the λh equation, the Wilson equation, and the nonrandom two liquid (NRTL) equation were used to correlate the experimental data. The NRTL equation was regarded as the effective model for all the solvents. Finally, the mixing properties were also calculated based on the NRTL equation. All these data were particularly instructive for the process of recycling naphthalene.
