SOLUBILITY AND VAPOR-PRESSURES IN SATURATED SOLUTIONS OF HIGH-MOLECULAR-WEIGHT HYDROCARBONS

Solubilities of C//1//8, C//1//9, C//2//0 n-paraffins (octadecane, nonadecane and eicosane) in 15 solvents have been measured over a wide range of temperature. Vapor-liquid equilibrium along the saturation line for the octadecane-cyclohexane system has also been determined. The solubility data of heptadecane, octadecane, nonadecane and eicosane have been described by five two-parameter correlation equations, namely the Redlich-Kister, van Laar and three versions of the Wilson equation and by the so called lambda h-equation.
