Excess molar enthalpies and excess molar heat capacities at T = 298.15 K were determined for {xCHCl3 Both experimental properties were represented by a Redlich-Kister type equation. The large negative values of the excess enthalpies and the positive values of the excess heat capacities observed in
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}
