Abstract
The hydrogen-bonded interactions by water and methanol in the first solvation shell of 2-aminopyrimidine, 2-, 3-, and 4-aminopyridine were determined by calorimetric analysis. The aminopyridines are enthalpically more stable in methanol than in water. This is due to methanol interactions at the amino nitrogen which do not seem to occur in water. The transfer enthalpies from water to methanol are determined primarily by the making and breaking of hydrogen bonds in the two solvents.Keywords
