Enthalpic and volumetric studies of the interactions of butanamide in aqueous alkan-1-ol solutions at 298.15 K

Enthalpies of solution and apparent molar volumes have been investigated for butanamide in aqueous methanol, ethanol and propanol solutions. Enthalpic and volumetric interaction coefficients have been calculated by a least-squares method. Pair interaction coefficients are discussed from the perspective of dipole–dipole and structural interactions. Triplet interaction coefficients are interpreted by the solvent separated association pattern.
