摘要：

The solubility of 3,4-dichloronitrobenzene and 2,3-dichloronitrobenzene in ethyl acetate, tetrachloromethane, cyclohexane, hexane, heptane, 1-propanol, 2-propanol, and 1-butanol were measured experimentally under temperatures of (278.15 to 303.15) K by employing the gravimetric method. The solubility of 3,4-dichloronitrobenzene or 2,3-dichloronitrobenzene in all organic solvents studied increases with increasing in temperature. Four models, the modified Apelblat equation, lambda h equation, Wilson model, and nonrandom two-liquid (NRTL) model, were employed to correlate the measured solubility. Results indicated that the modified Apelblat equation was the better model than the other models. The solubility data would be very useful for optimizing the purification process of 3,4-dichloronitrobenzene and 2,3-dichloronitrobenzene on the industrial scale.
