PRESSURE 2ND VIRIAL-COEFFICIENTS OF HYDROCARBONS, FLUOROCARBONS, AND THEIR MIXTURES - INTERACTIONS OF WALKS

Molecules of some hydrocarbons and fluorocarbons have been represented by graphs, and walks on graphs considered. The walk interaction formalism developed previously for liquid state properties has been applied to gas pressure second virial coefficients of n-alkanes, n-pertluorocarbons, and alk-1-enes. Agreement between experiment and calculation within limits of the experimental accuracy has been obtained. For each class of compounds properties of the respective binary mixtures have been predicted in terms of properties of pure compounds, without the use of any combining rules; again satisfactory agreement with available experimental data has been found. © 1979 American Institute of Physics.
