Reasonable estimates of ternary solid-liquid equilibrium can be obtained by application of the Scatchard-Hildebrand, UNIFAC and Wilson models. The solubilities of C18, C19 n-paraffins (octadecane and nonadecane) in 20 binary solvents consisting of cyclohexane and heptane or ethanol, as well as of C20 n-paraffin (eicosane) in three binary mixed solvents of 2-propanol with cyclohexane, trichloroethylene or tetrachloroethylene have been measured by a dynamic method from 275 to 279 K. The root mean square deviations of the solubility temperatures for all measured data in nonpolar solvents vary from 0.1 to 4.0 K and depend on the equation used. The best representation was obtained with the Wilson equation utilizing temperature dependent Λijparameters. The correlation of solubility curves with λh-equation has been done. 1987.
