Excess molar volumes were determined over the whole composition range for (dimethyl carbonate, or diethyl carbonate + n-heptane) at the temperatures (278.15, 288.15, 298.15, and 308.15) K, and at atmospheric pressure with a vibrating-tube densimeter. In addition, a differential scanning calorimeter
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}
The heat capacities of dilute aqueous solutions of 1-propanol, butane-1,4-diol, and hexane-1,6-diol have been measured at 300 K Q T Q 525 K at p = 28 MPa. Extrapolation to infinite dilution gave values for C a p,2 . Literature values of (1 2 V a 2 /1T 2 ) and C a p,2 at p = 0.1 MPa were used to calc
