Abstract

Values of the enthalpy changes for the transfer of some aliphatic primary, secondary, and tertiary amines from gas state to dilute solutions in octan-1-ol have been obtained as a difference between the enthalpies of solution, determined by calorimetry, and the enthalpies of vaporization of the pure liquid amines. A comparison is made between these data and the corresponding enthalpies of hydration; the values of the enthalpies of partitioning of the amines between pure water and pure octan-1-ol phases have been also calculated. Lastly, some observations are made with respect to the relations between the molecular structure of the amines and their enthalpies of solvation in octanol, in water, and in their pure liquid state.
