Recommended vapor pressure data for ferrocene (CAS Registry Number: 102-54-5) in the temperature range from 242 K to 447 K were developed by the simultaneous correlation of critically assessed vapor pressures, heat capacities of the crystalline phase and the ideal gas, and calorimetrically determined enthalpies of sublimation. All of the properties needed for the correlation were newly determined in this work. The value for the enthalpy of sublimation, Delta(g)(cr) H-m(298.15 K) = (74.38 +/- 0.38) kJ.mol(-1), is recommended. Comparisons with literature values are shown for all measured and derived properties. (C) 2012 Elsevier Ltd. All rights reserved.
