A theoretical and experimental study of the equation of state of tetrafluoromethane

The density of tetrafluoromethane has been measured from 95 to 413 K and pressures up to 1100 bar. The results have been correlated in terms of the Strobridge equation of state, and the orthobaric density and enthalpy of varporization have been calculated and compared with results from the literature. The ability of both a variational treatment (VIM) and a perturbation theory to predict the experimental values of density and configurational energy has been examined. 40 references, 8 figures, 5 tables.
