MARTINEZ, Fleming; AVILA, Carolina M. y GOMEZ, Alfredo. Thermodynamic study of the solubility of some sulfonamides in cyclohexane. J. Braz. Chem. Soc. [online]. 2003, vol.14, n.5, pp. 803-808. ISSN 0103-5053. http://dx.doi.org/10.1590/S0103-50532003000500016.
The thermodynamic functions Gibbs energy, enthalpy and entropy of solution in cyclohexane, were evaluated from solubility data for a group of sulfonamides over the temperature range from 20.0 to 40.0 °C. The excess Gibbs energy and the activity coefficients of the solutes were also determined. The results are discussed in terms of solute-solvent interactions.
