摘要：
Enthalpies of solution and apparent molar volumes have been determined for butyramide in aqueous formic acid, acetic acid and propionic acid solutions using a C-80 microcalorimeter and vibrating tube digital densimeter. From the data, enthalpic and volumetric interaction coefficients were obtained. The pair interaction coefficients are discussed from the point of view of dipole-dipole and structural interactions and we have also tried to interpret the triplet interaction coefficients according to the solvent separated association pattern.
