Determination and Correlation of Solubilities of Lauric Acid in Eight Alcohols

The solubilities of lauric acid in methanol, ethanol, propanol, n-butanol, n-pentanol, n-hexanol, isobutanol, and isoamylol were measured by synthetic method in the temperature ranging from (276.17 to 306.12) K. Results of these measurements were correlated by the modified Apelblat equation, the lambda h equation and activity coefficient models (NRTL and UNIQUAC). It was found that the modified Apelblat equation and the lambda h equation gave better correlation results. The thermodynamic properties of the solution process, including the Gibbs energy, enthalpy, and entropy were calculated by the vant Hoff analysis.
