Abstract

Abstract The excess free energies of aqueous solutions containing N-acetyl-L-prolinamide, N-acetyl-N-methyl-L-alaninamide and binary mixtures of these have been determined at 25° C from isopiestic measurements. The corresponding excess enthalpies for the last two systems have been obtained from enthalpy of dilution measurements. The results derived have been considered using the Savage-Wood group additivity principle, and it is shown ...
