ABSTRACT

Enthalpies of dilution of formamide in aqueous n-propanol, 1,2-propanediol and glycerol solutions have been determined by isothermal calorimetry at 298.15 K. The values of dilution enthalpy were used to determine homogeneous enthalpic interaction coefficients which characterize the interactions of formamide in alcohol solutions. The variations of the enthalpic pairwise interaction coefficients with the mass fraction of alcohol in mixtures are interpreted in terms of solute solute and solute solvent interactions.
