| Popis: | A flow mixing calorimeter followed by a vibrating-tube densimeter has been used to measure excess molar enthalpies H m E and excess molar volumes V m E of { x C 3 H 8 + (1 − x )SF 6 } . Measurements over a range of mole fractions x have been made at the pressure p = 4.30 MPa at eight temperatures in the range T = 314.56 K to 373.91 K, in the liquid region at p = 3.75 MPa and T = 314.56 K, in the two phase region at p = 3.91 MPa and T = 328.18 K, and in the supercritical region at p = 5.0 MPa and T = 373.95 K. The measurements are compared with results from the Patel–Teja equation of state which reproduces the main features of the excess function curves as well as it does for similar measurements on { x CO 2 + (1 − x )C 2 H 6 } , { x CO 2 + (1 − x )C 2 H 4 } and { x CO 2 + (1 − x )SF 6 } reported previously. |
