Excess enthalpies for ethane + acetonitrile at 298.15, 323.15, and 348.15 K and at 7.5 and 15 MPa

Excess enthalpies and excess volumes for (ethane + propan-1-ol) at the temperatures (298.15, 323.15, and 348.15) K and at the pressures (5, 10, 12.5, and 15) MPa

“…Also, no attempt was made to fit to equation (1) (The results at p=5 MPa are excluded from the comparison.) In an earlier paper, (17) in which we reported H E m for (ethane+acetonitrile), we found a large change in H E m from negative to positive values as p increased over approximately the same pressure range, and attributed it to a change from gas-like to liquid-like behavior of the supercritical ethane. The (1V E m /1T ) p is large and increases with decreasing p as shown in figure 3(a).…”

Excess enthalpies for (ethane + ethene) at the temperatures (273.15, 298.15, 323.15, 348.15, and 363.15) K and the pressures (5, 7.5, 10, 12.5, and 15) MPa

“…15 (7) for ethane and by Younglove (8) for ethene. All of the above pressure conditions at T=293.15 K were outside the critical region where uncertainties in the equations of state are relatively large, as described in references 7 and 8, and hence, the maximum deviations of the densities used by us are 0.005·r and 0.003·r for ethane and ethene, respectively.…”
