Studies of homogeneous interactions of N-acetyl-N′-methyl-l-α-amino acid amides in water at 298.15 K

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