Abstract

The isomer effects on the equilibrium partition coefficients of the two propanol, the four butanol, and two of the pentanol isomers between water and immiscible solvents are shown to be governed primarily by the abilities of the alkanols to donate and accept hydrogen bonds. These abilities depend directly on the number of methyl groups bonded to the carbon atom that carries the hydroxyl group. The overall partition coefficient, irrespective of the isomeric form, depends on the total number of carbon atoms in the alkanol via its molar volume. The dependencies on the natures of the extracting solvents are also rationalized in terms of their cohesive energy density, their polarity and polarizability, and their hydrogen bond donation and acceptance abilities.
