✦ Synopsis

Excess molar enthalpies (H_{\mathrm{m}}^{\mathrm{E}}) and excess molar volumes (V_{\mathrm{m}}^{\mathrm{E}}) have been determined for (\left{x \mathrm{CH}{3}\left(\mathrm{CH}{2}\right){2} \mathrm{CH}{3}+(1-x) \mathrm{CH}{3}\left(\mathrm{CH}{2}\right){2} \mathrm{CH}{2} \mathrm{OH}\right}) at the temperatures (298.15, 323.15, and 348.15) (\mathrm{K}) and at the pressures ((5,10), and 15() \mathrm{MPa}). The results are explained in terms of chemical, physical, and structural effects. A comparison is made of (\left(\partial H_{\mathrm{mn}}^{\mathrm{E}} / \partial p\right){T}), the pressure coefficient of (H{\mathrm{m}}^{\mathrm{E}}), as determined directly from the (H_{\mathrm{m}}^{\mathrm{E}}) results and as calculated from (V_{\mathrm{m}}^{\mathrm{E}}) and the temperature derivative of (V_{\mathrm{m}}^{\mathrm{E}}).
