Abstract Heats of solution of 13 1∶1 electrolytes in 1-propanol have been determined calorimetrically at various electrolyte concentrations, and extrapolated to zero concentration to give ΔH s o values for these electrolytes. Together with literature data on three additional 1∶1 electrolytes, these measurements yield a self-consistent set of single-ion enthalpies of transfer from water to 1-propanol. Values are tabulated for 10 univalent cations and five univalent anions. It is shown that the ΔH t o (Ph 4 As+)=ΔH t o (Ph 4 B−) assumption yields chemically reasonable single-ion values. Using this assumption, it may be deduced that all the univalent ions studied have about the same enthalpy in 1-propanol as in methanol.
