Phenol-pyridine enthalpies and free energies of hydrogen bond formation in cyclohexane, CCl4, and benzene solvents have been determined by calorimetric measurements.Schematic mapping techniques show that only 1:1 phenol-pyridine complexes exist in solution under the experimental conditions used.The enthalpy differences in the three solvents are explained in terms of dipolar and specific interactions of the acid base with solvent.

The mixtures of phenol and some heterocyclic bases of biological importance have been studied by i.r. spectroscopy in CCl4 and equilibrium constats (K) and thermodynamic data (ΔH, ΔG, DΣ) have been determined at 25 and 40 deg C.The formation constants of hydrogen-bridged phenol complexes were found to be related to the protonation constants of the bases, but no strict linearity can be proved in many cases.The participation of the non-bonded electron pair of the heteroatom in the ?-system of the rings play a dominating role in the proton-acceptor processes.
