- Acetone isotherms

- Casado, Massie and Whytlaw-Gray measured the density of five organic vapours at 22° C with a quartz-fibre microbalance and obtained results which permit the calculation of second virial coefficients. However, with acetone, the data imply a contribution over the experimental pressure range (26-136 mm) of a positive third virial coefficient sufficiently large to cause a two-fold change in the slope of the PV/P line, a finding quite at variance with Lambert's linear isotherms. Work on acetone by Pennington and Kobe and Zaalishvilli and Kolysko was conducted by methods which do not provide direct evidence on the PV/P curvature. Recent PVT determinations at sub-atmospheric pressure for other organic compounds boiling near 50° C indicate that any supposed curvature is scarcely distinguishable from observational errors.
