Enthalpy of sublimation of dibenzofuran: a redetermination
Physical Chemistry Chemical Physics, 2003Molar enthalpies of sublimation and molar enthalpies of vaporization of dibenzofuran were obtained from the temperature dependence of the vapor pressure measured by the transpiration method. New results help to resolve the uncertainty in the available thermochemical data on dibenzofuran.

The standard enthalpy of sublimation of naphthalene
The Journal of Chemical Thermodynamics, 1972Abstract The standard enthalpy of sublimation of naphthalene has been determined calorimetrically at 298.15 K. The value obtained, (73.00 ± 0.25) kJ mol−1 is in agreement with the accepted value derived from vapour pressure measurements.

Microwave-assisted synthesis and sublimation enthalpies of hemiporphyrazines
Journal of Porphyrins and Phthalocyanines, 2019It was established that microwave irradiation solvent-free processing of 2,6- diaminopyridine or 1,3-phenylenediamine with phthalonitrile or 4-tert-butylphthalonitrile led to corresponding hemiporphyrazines with sufficiently high yields and a huge reduction in the time required for synthesis, from 8–12 h to 20 min.

Molar enthalpies of sublimation of 1,2,4-, 1,2,3-, and 1,3,5-tri-hydroxy-benzene, were obtained from the temperature dependence of the vapor pressure measured by the transpiration method. The molar enthalpies of fusion and molar heat capacities of these compounds were measured by DSC.

Sublimation pressure and sublimation enthalpy of H2O ice Ih between 0 and 273.16 K
Geochimica et Cosmochimica Acta, 2007Abstract The sublimation of water in the region of extremely low pressures and temperatures meets increasing interest for the exploration of icy cosmic bodies. At temperatures below 130 K, the shape of the sublimation curve of H2O is not known; neither experimental data nor theoretical treatments exist for this region.
