Abstract
The dilution enthalpies of formamide in aqueous n-propanol and i-propanol solutions have been determined using a CSC-4400 isothermal calorimeter at 298.15Â K. The homogeneous enthalpic interaction coefficients in the range of propanol concentration (0%-30%) have been calculated according to the excess enthalpy concept. The results are interpreted in terms of solute-solute and solute-solvent interactions. Hydroxyl groups present different efficiency in promoting hydrophobic interactions in dependence of their position in the interacting molecules.
