The densities of the mixtures (hexane or cyclohexane+propan-2-ol or butan-2-ol) at the temperatures (288.15 and 298.15) K have been measured using a vibrating-tube densitometer. Excess molar volumes V E m were calculated. The results were described by means of the ERAS model. All mixtures exhibit po

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
Excess volumes of (1,2-dichloroethane or 1,2-dibromoethane + each of several isomers of butanol) have been determined from density measurements at the temperatures \(298.15 \mathrm{~K}\) and \(313.15 \mathrm{~K}\) using an Anton-Paar dersimeter. The results show that excess volumes are positive over
Excess molar enthalpies H E m and excess molar volumes V E m have been determined for (butane+propan-1-ol) at temperatures (298.15, 323.15, and 348.15) K and at pressures (5, 10, and 15) MPa. The H E m results and the excess molar heat capacity C E p,m are positive, while V E m (x) is s-shaped, chan
