The solubilities of lauric acid in n-hexane, acetone, 2-propanol, propanol, 1-bromopropane, and trichloroethylene have been measured using a dynamic equilibrium method from (279.0 to 315.3) K. All systems present positive deviations of the ideal behavior. The solvent that presented the lowest average deviation, concerning the ideality of the system, was trichloroethylene, and the highest value of deviation was found in acetone. The experimental solubility data were correlated with the NRTL, Wilson, and UNIQUAC models. In the n-hexane case, the correction for the existence of dimers was applied. The best results were obtained using UNIQUAC with 0.26 K average root-mean-square deviation of temperature. The solubility in pure solvents decreased in the order: trichloroethylene greater than 1-bromopropane greater than 2-propanol greater than propanol greater than acetone greater than n-hexane.
