The equilibrium solubilities of sodium 3-nitrobenzenesulfonate and sodium 4-nitrobenzenesulfonate in ethanol, acetone, 1-butanol, ethyl acetate, cyclohexanone, and tetrahydrofuran were measured experimentally by using a steady-state method at temperatures ranging from 283.15 to 323.15 K under 101.3 kPa. The solubilities of sodium 3-nitrobenzenesulfonate increased faster in ethanol than in the other solvents as the temperature increase. The order of the solubility values from high to low was: ethanol > acetone > tetrahydrofuran > 1-butanol > ethyl acetate > cyclohexanone. For the systems of sodium 4-nitrobenzenesulfonate + solvents, the sequence of the mole fraction solubility data was: acetone > ethanol > (cyclohexanone, 1-butanol) > (ethyl acetate, tetrahydrofuran). The experimental solubility data were correlated with the modified Apelblat equation and λh equation. The results indicated that the calculated values via the modified Apelblat equation agreed well with experimental results for sodium 3/4-nitrobenzenesulfonate.
