Heats, equilibrium constants, and free energies of formation of the alkylbenzenes

For benzene, toluene, ethylbenzene, the three xylenes, normal and isopropylbenzene, the three methylethylbenzenes, the three trimethylbenzenes, and the higher normal alkylbenzenes, values are presented for the following thermodynamic properties for the gaseous state to 1,500 K: The heat-content function, (HO-H~)/T; the free-energy function, (FO-Hg)/T; the entropy, So; the heat content, HO-Hg the heat capacity, C;; the heat of formation from the elements, t..HjO; the free energy of formation from the elements, t..FjO; and the logarithm of the equilibrium constant of formation from the elements, 10glO Kf.
