Mutual Solubilities of Hydrocarbons and Water at 0 and 25 °C

Mutual solubilities of 14 paraffinic and 6 aromatic hydrocarbons and water were determined experimentally at 0 and 25 °C. The solubilities are generally smaller at 0 than at 25 °C except the solubilities of paraffins in water which are larger at 0 than at 25 °C. The coefficients of the Redlich–Kister equation were evaluated from the experimental data and correlated as a function of molar volume of liquid hydrocarbons and group contributions. The correlation allows calculation of the mutual solubilities of paraffinic and aromatic hydrocarbons and water at 0 and 25 °C from the knowledge of the molar volume of liquid and the contribution of their component groups.
