ABSTRACT
The enthalpies of dilution of aqueous solutions of N-acetyl-N -methyl-l-glycinamide (AcGlyNHCH3), N-acetyl-N -methyl-l- -alaninamide (AcAlaNHCH3),N-acetyl-N -methyl-l- -valinamide (AcValNHCH3), N-acetyl-N -methyl-l- -leucinamide (AcLeuNHCH3) (BACHEM) and N-acetyl-N -methyl-l- -serinamide (AcSerNHCH3), N-acetyl-N -methyl-l- -threoninamide (AcThrNHCH3), in water at 298.15K have been measured. These data were used to calculate the homogeneous enthalpic pair interaction coefficients based on McMillan Mayer s theory.
