ChemInform Abstract: Condensed-Phase Heat Capacities and Derived Thermodynamic Properties for 1,4-Dimethylbenzene, 1,2-Diphenylethane, and 2,3-Dimethylnaphthalene

Condensed-phase heat capacities and enthalpies were determined at temperatures from 10 to near 400 K for 1,4-dimethylbenzene, 1,2-diphenylethane, and 2,3-dimethylnaphthalene, and were used to provide values of enthalpies, entropies, and heat capacities at vapor saturation. Enthalpies and entropies for the ideal-gas state were determined at selected temperatures with available vapor pressures and enthalpies of vaporization. The enthalpies, entropies, and Gibbs energies of formation, also at selected temperatures, were derived for the ideal-gas state with available enthalpies of combustion.
