The enthalpy of vaporization and sublimation of corannulene, coronene, and perylene at T= 298.15 K

Vapour pressure and enthalpy of vaporization of cyclic alkylene carbonates

“…with the literature value l cr H m (T fus ) determined in a calorimetric experiment [14] and adjusted to the reference temperature 298.15 K. A value for enthalpy of fusion, l cr H m (T fus ) = 13.3 kJ mol −1 , was reported in [14] at the melting temperature, T = 309.49 K. The following equation [16] was applied to experimental l cr H m (T fus ) to account for the temperature correction of l cr H m to 298.15 K Values of the experimental isobaric molar heat capacity of liquid ethylene carbonate, C l p = 136.2 J mol −1 K −1 and the isobaric molar heat capacities of the solid ethylene carbonate, C cr p = 117.4 J mol −1 K −1 , were reported in [14].…”

Vapour pressures and enthalpies of vaporization of a series of the ferrocene derivatives

“…Thus, a valuable test of the consistency of the experimental data presented in table 2 on sublimation and vaporization enthalpies of ferrocene should be the comparison of the difference between sublimation and vaporization enthalpies for this compound with the value of the fusion enthalpy derived by the direct calorimetric methods. The experimental enthalpy of fusion, D l cr H m ðT fus Þ ¼ ð18:3 AE 0:2Þ kJ Á mol À1 of ferrocene was measured at the melting temperature of 448.7 K [8], and due to the deviation of the melting temperature from T = 298.15 K the observed value of the enthalpy of fusion of ferrocene had to be adjusted to the reference temperature of 298.15 K. The adjustment was calculated using the equation [27]: where value of D l cr C p has been derived from the isobaric molar heat capacities of the liquid ferrocene, C l p ¼ 238:9 J Á mol À1 Á K À1 calculated according to procedure developed by Chickos et al [23,24]. The isobaric molar heat capacity of the solid ferrocene, C cr p ¼ 192:5 JÁ K À1 Á mol À1 was taken from reference [28].…”

The thermochemistry of coronene revisited

“…These fields include mechanistic studies of thin film deposition from coronene in the gas phase, the production of homogeneous layers of the compound by melting, the understanding of the solvation process in water, and the computation of its resonance and bond energies for the posterior application in the elucidation of the energetics of carbon clusters. Unfortunately, data for this polycyclic aromatic hydrocarbon are scarce [8,9] and dispersed over a wide range [10][11][12][13][14][15][16].…”
