Abstract
A comprehensive study of pressure, volume, temperature relations for ethane includes new experimental vapor pressures to the critical, orthobaric densities for the coexistence envelope, critical constants (pc = 4871.76 kN m-2 or 48.0807 atm, Tc = 305.33 K, Vc = 0.14556 dm3 mol-1, and pc = 6.870 mol dm-3), virial coefficients B0, C0, and D0, and compression factors Z = pV/RT in the compressed fluid to 400 atm and 623 K. The effect of gravity on the density of near-critical fluids and the critical point was significant even for small fluid heights (2 cm). The diameter of the coexistence envelope, (p1 + pg)/2, had a gradual curvature at all temperatures up to the critical.
