摘要
The dilution enthalpies of formamide in aqueous ethylene glycol solutions were determined by using a CSC- KG-1/54400 isothermal calorimeter at 298.15 K. The homogeneous enthalpic interaction coefficients in the range of ethylene glycol mass fraction(0%\_40%) were calculated according to the excess enthalpy concept. The results show that enthalpic pair interaction coefficients h_ 2 of formamide are negative in aqueous ethylene glycol solutions and pass through a minimum at w≈0.20 of ethylene glycol in mixed solvents.
