ABSTRACT
The dilution enthalpies of N,N-dimethylformamide (DMF) in aqueous ethylene glycol and glycerol solutions have been determined using a CSC-4400 isothermal calorimeter at 298.15 K. The experimental data have been analyzed in terms of McMillan Mayer formalism to obtain the enthalpic virial coefficients for heterotactic interaction. The results have been interpreted from the point of view of solute solute interactions and solute solvent interactions.
