Calculation Method of Heat Capacity Change during Organic Compounds Vaporization and Sublimation
Year: 2016
Type: article
Abstract: On the basis of literature data the constancy of heat capacity change during vaporization ( ± 2 %) and sublimation (± 8 %) has been determined at 298 K for different organic compounds.The obtained equations allow to recalculate the enthalpy according to Kirchhoff's law easier compared with present techniques based on the increments method.The vaporization and sublimation enthalpies of 5-(2-nitrophenyl)-furan-2-carbaldehyde have been determined and recalculated for 298 K for the reliability proofing of the suggested method.
