摘要
The solubilities of 2,3-dichloronitrobenzene in aqueous solutions of methanol and ethanol with various concentrations were determined at temperatures ranging from (278.15 to 303.15) K under atmospheric pressure of 0.1 MPa. The solubility of 2,3-dichloronitrobenzene increases with increments in both temperature and mass fraction of methanol or ethanol. The solubility data were correlated by five models, which are the JouybanAcree model, van't HoffAcree model, modified ApelblatAcree model, Ma model, and Sun model. The calculated solubility using the JouybanAcree model shows better agreement with the experimental data than those by the other models. The thermodynamic properties, molar dissolution enthalpy, molar dissolution entropy, and Gibbs free energy change of dissolution process of 2,3-dichloronitrobenzene in two mixed solvents were calculated.
