| Abstract: | Enthalpies of dilution of urea dissolved in mixtures of water and N,N-dimethylformamide with mole fractions of water 0.33, 0.50 and 0.67, respectively, have been measured calorimetrically at 25°C. From these, enthalpic interaction coefficients were obtained. The present results are compared with those of urea dissolved in pure water and in pure N,N-dimethylformamide. |
