AbstractThe mutual solubilities at the three‐phase equilibrium pressure of three C6hydrocarbons (benzene, cyclohexane andn‐hexane) and water have been experimentally investigated up to 482 K. A thermodynamic analysis of these new measurements and of critically selected literature data has been carried out to the three‐phase critical end point. Information is also provided on the two‐phase critical locus. The solubility of hydrocarbons in water has been used to calculate Henry's constants, while the solubility of water in the hydrocarbons has been correlated with a modified version of the Redlich‐Kwong equation of state. Consideration is also given to the effect of pressure on the mutual solubilities.
