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.

Abstract The standard (p∘ = 0.1 MPa) molar enthalpies of formation, in the crystalline state, of 1,5-diaminonaphthalene and 1,8-diaminonaphthalene were derived from the standard molar energies of combustion, in oxygen, at T = 298.15 K, measured by static-bomb combustion calorimetry.

Ferrocene: Temperature adjustments of sublimation and vaporization enthalpies
Fluid Phase Equilibria, 2018Abstract Knowledge of the vapor pressures and the sublimation/vaporization enthalpies of a metalorganic precursor can be indispensable for optimizing a deposition process. Unfortunately, published measurements of those values are often referred to a unique temperature, and comparing such studies requires adjusting the data to a common temperature. We

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.

Microcalorimetric determination of the enthalpy of sublimation of cadmium
The Journal of Chemical Thermodynamics, 1971A Calvet microcalorimeter was used to determine the standard sublimation enthalpy Δ H ° vap of cadmium in the temperature range 498 to 590K. The Knudsen mass loss method was used, simultaneously, to determine the vapour pressure of cadmium. Second and third law treatment of the results gave values of Δ H ° vap (298.15K) sublimation of (26636 ± 73 ...
