✦ Synopsis

Excess enthalpies and excess heat capacities at the temperature (298.15 \mathrm{~K}) were determined for (\left{x \mathrm{HCON}\left(\mathrm{CH}{3}\right){2}+(1-x) c-\left(\mathrm{CH}{2}\right){4} \mathrm{O}\right}) and for (\left{x_{1} \mathrm{HCON}\left(\mathrm{CH}{3}\right){2}+x_{2} c-\left(\mathrm{CH}{2}\right){4} \mathrm{O}+\right.) ( (\left.\left.1-x_{1}-x_{2}\right) c-\mathrm{C}{6} \mathrm{H}{12}\right}). Both experimental properties were described through an empirical equation. Enthalpies were also described through UNIQUAC and UNIFAC models. The ternary mixture behaves very similarly to the other ternary mixture, previously studied, in which (c-\left(\mathrm{CH}{2}\right){4} \mathrm{O}) was replaced by (\mathrm{C}{2} \mathrm{H}{5} \mathrm{OH})
