ABSTRACT
The solubility of a-5-(dithiolan-3-yl)pentanoic acid in mixed solvents (cyclohexane + ethyl acetate, heptane + ethyl acetate, and hexane + ethyl acetate) was experimentally studied by an analytical method. The data obtained were correlated by a semiempirical equation. Results showed that the solubility of 5-(dithiolan-3-yl)pentanoic acid increased with increasing temperature. In the same solvent systems, the molar fraction solubility increased with a decreasing solvent volume ratio.
