The inthalpies of dilution of glycine in water,DBF/water and ethanol/water mixtures(in10% increments ranging from 5%to 45% DBF or ethanol by weight) have been measured with LKB 2277 Bio Activity Monitor at 298.15K.Calculations show that pairwise enthalpic interaction coefficients h~2 is closely connected with solvent properties. The values of h~2 decrease with increasing DMF concentrationand reach a minimum at 25% ethanol in ethanol/water mixtures.
