โœฆ Synopsis

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, changing from negative to positive with increasing mole fraction x of butane. The values of (1H E m /1p)T calculated from the H E m results are compared with those calculated from V E m and found to be in reasonable agreement. Comparisons are made of H E m (x) and V E m (x) at T = 298.15 K and p = 15 MPa for propane with other similar alkanols.
