Enthalpies of solution into water of formamide, N-methylformamide, N,N-dimethylformamide, acetamide, N-methylacetamide, N,N-dimethylacetamide, N-acetylglycinamide, N-acetyl-L-alaninamide, N-acetyl-L-leucinamide, N-acetyl-L-prolinamide, N-acetyl-N′-methylglycinamide, N-acetyl-N′-methyl-L-alaninamide, N-acetyl-N′-methyl-L-leucinamide, and N-acetyl-N′-methyl-L-prolinamide, have been measured calorimetrically at 298.15 K. In addition, the enthalpies of solution at the same temperature of all the above into (urea + water), and of the amino-acid amides into the solvent N,N-dimethylformamide, have also been obtained.
