Vapor pressures (6.35-817.29 mmHg) of xanthene, a polynuclear aromatic (three-ring) compound containing an oxygen group, over the temperature range 423-589 K, were measured. The measurements were performed in a high-temperature static apparatus. Chebyshev polynomials have been used to fit the experimental vapor pressure data. The results have been further processed to evaluate the enthalpies of vaporization and compared with the predicted enthalpy values, by a recently developed generalized correlation which incorporates the renormalization group theory with the corresponding states principle. The entropies of vaporization were also evaluated at their respective temperatures for xanthene. 12 references, 4 figures, 7 tables.
