Abstract
Enthalpies of dilution both of solutions of N-acetylsarcosinamide and of ternary solutions equimolal in N-acetylsarcosinamide and N-acetylglycinamide, N-acetyl-L-alaninamide, N-acetyl-L-valinamide or N-acetyl-L-leucinamide have been determined by a microcalorimetric method. The results were employed to calculate the pairwise enthalpic coefficients for both homotactic (like-like) and heterotactic (like-unlike) solute interactions. These pairwise interaction coefficients have been analyzed by means of a group additivity approach and some comments on the utility of this, when applied to such systems, are made.
