| Abstract: | Consistent values of the air/water partition coefficient for n-pentane, n-hexane, n-heptane, n-octane and n-nonane have been measured in the temperature range 15–35°C. All of the results may be summarised by an equation derived on the basis of thermodynamic principles. The constants of this equation have been determined by least-squares regression. The solubilities of hydrocarbons in water as well as thermodynamic quantities relating to the solvation process can be predicted using the equation. |
