“…4, the values for the second virial coefficient calculated semiclassically using the adjusted potential function, B QFH 2,adj , are compared with values calculated semiclassically using the unadjusted potential function, B QFH 2,unadj , and classically using the adjusted one, B cl 2,adj , as well as with selected experimental data [44][45][46][47][48][49][50][51] and values derived from the current reference equation of state (EOS) of Lemmon et al 52 The experimental values of Trusler et al 50 and of Glos et al 51 at 300 K were used as reference for the adjustment of the analytical potential function described in Sec. II C, which lowers the calculated value of the second virial coefficient at this temperature from 347.0 cm 3 mol 1 to 384.8 cm 3 mol 1 .…”

A six-dimensional potential energy surface (PES) for the interaction of two rigid propane molecules was determined from supermolecular ab initio calculations up to the coupled cluster with single, double, and perturbative triple excitations level of theory for 9452 configurations. An analytical site-site potential function with 14 sites per molecule was fitted to the calculated interaction energies. To validate the analytical PES, the second virial coefficient and the dilute gas shear viscosity and thermal conductivity of propane were computed. The dispersion part of the potential function was slightly adjusted such that quantitative agreement with the most accurate experimental data for the second virial coefficient at room temperature was achieved. The adjusted PES yields values for the three properties that are in very good agreement with the best experimental data at all temperatures.

An apparatus is described which can be used for PVT and compressibility measurements on 5upercritical fluids from near room temperature to 600 °C and pressures to 35 MPa. Two separate experimental techniques are employed to obtain PVT data over a broad range of the state surface. Burnett expansions are performed to generate compressibility factor (or equivalently density) data along a well-behaved supercritical isotherm. A series of isochoric measurements is then made to extend the temperature range. Densities assigned to the isochores are determined from their intersection with the previously measured Burnett isotherm or gravimetri~ cally. A computer is used for experimental control and for data logging. Isochoric measurements lasting several days can be performed routinely and without operator attention. The apparatus has been tested on propane to a temperature of 325 ·C. The density data, estimated accurate to ±O.l percent, are in excellent agreement with other existing data.
