✦ Synopsis

Literature values of the Ostwald solubility coefficient of gases and vapours in propan-1-ol at 298 K were combined with additional values calculated from solubilities in propan-1-ol and vapour pressures to yield a total of 79 log L PrOH values at 298 K. Seventy-seven of these values were correlated through the general solvation equation to give the regression

A correlation equation was also constructed for the transfer of solutes from water to propan-1-ol. Both equations suggest that propan-1-ol as a solvent is less dipolar, more acidic and less basic than methanol or ethanol, but the differences between the three alcohols are very small. Comparison with equations for transfer to wet alcohols shows that the addition of water to alcohols has little effect on their dipolarity/polarizability or hydrogen bond basicity, but considerably increases the hydrogen bond acidity. The wet alcohols are more hydrophilic (less hydrophobic) than the dry alcohols.
