Summary

Experimental details of vapor pressure, enthalpy of combustion, and condensed-phase heat-capacity studies are reported for 2-ethylbiphenyl, 2,2'-dimethylbiphenyl, and 1,2,3,4-tetrahydrophenanthene. The results are combined to produce values of the Gibbs energy of formation in the ideal-gas state at selected temperatures for each molecule. Revised ideal-gas state properties, based on new experimental information, are tabulated for phenanthrene and 9,10-dihydrophenanthrene. Results are used in equilibria calculations for abbreviated phenanthrene/hydrogen reaction networks. Reaction networks with and without ring opening are considered. Several generalizations are drawn concerning reaction conditions necessary to produce specific products. Calculated equilibrium concentrations for non-ring-opened species are compared with experimental values from the literature derived by batch reaction and detailed analyses. Finally, several related kinetic and coal-liquefaction studies, which illustrate the importance of both thermodynamic and kinetic (i.e., catalytic) considerations in reaction path determination, are discussed. Estimates, based on group-additivity methods, for the ideal-gas state properties for a series of dialkylnaphthalenes are provided in an appendix. 56 refs., 15 figs., 22 tabs.
