“…The BWR equation of state was used to calculate the density of the gas phase, ρ g ( T , P ). The values of the coefficients in the BWR (Benedict−Webb−Rubin) equation of state given by Canjar et al were used in the calculation of the propylene vapor density. The experiments using ethylene were conducted in the vicinity of its critical point (9.9 °C, 742.1 psia).…”

In this work, the static sorption technique has been extended to measure the diffusivity as well as the solubility of gases in polymers at elevated pressures. This has been accomplished by operating several static sorption capsules in parallel in order to measure the fractional mass uptake of a gas by a polymer with time. Equilibrium and diffusion data of propylene and ethylene in atactic polypropylene have been measured in the temperature range of 25-70 °C. The groupcontribution, lattice-fluid equation of state (GCLF-EoS) was used to correlate the equilibria data with a single value of the binary interaction parameter for each of the systems. The Vrentas-Duda free-volume theory was employed to describe the propylene and ethylene diffusivity data. The chemical potential gradient used in the free-volume correlation of the diffusivity data was obtained from the GCLF-EoS.

“…To test this conslusion, densities for seven substances having ze values from 0.273 to 0.277 have been calculated from Figures 3 and 4 and compared with the experimental values found in the literature. The nonpolar substances, acetylene (53), propane (56), propylene (12), re-butane (52), and chlorine (66) have been considered in this study as well as dichlorodifluoromethane, Freon 12 (8), and methyl chloride (58) which possess dipole momnets of 0.51 and 1.97 debye units, respectively. In these comparisons density values have been considered for the saturated liquid and vapor states as well as for regions away from the saturated envelope.…”

“…On the Ln P vs. 1/7 plot, the data fell about a straight line covering the range -20°to 160°F. Both the Antoine equation B Log P = A + -+ (1) and the Kelvin equation B Ln P = A+y (2) were used to correlate the data by standard regression analysis techniques. The Kelvin equation performed much better than the Antoine equation in that it was not necessary to alter the temperature scale to account for any deviation from linearity over the temperature range of interest.…”
