文摘

Enthalpies of solution and apparent molar volumes have been measured for formamide in aqueous methanol, ethanol and propanol solutions by using a C-80 microcalorimeter and vibrating tube digital densimeter. According to these data, enthalpic and volumetric interaction coefficients were obtained. The pair interaction coefficients are discussed from the perspective of dipole–dipole interaction and structural interaction. At the same time, attempts have been made to interpret the triplet coefficients by using the solvent separated association pattern.
