Verevkin, Sergey P. published the artcileThermochemical properties of pyrazine derivatives as seminal liquid organic hydrogen carriers for hydrogen storage, SDS of cas: 14667-55-1, the main research area is pyrazine derivative thermochem property hydrogen storage vapor pressure enthalpy; vaporization sublimation fusion formation.
This work contributes to our primary interest in applications of exptl. and computational thermochem. methods for providing the basic data required in chem.-process design. Pyrazine derivatives are considered as a seminal liquid organic hydrogen carriers. The standard molar enthalpies of vaporisation/sublimation of pyrazine derivatives were derived from the vapor pressure temperature dependences measured by the static and transpiration method. Enthalpies of fusion of the solid compounds were measured using DSC. Thermodn. data on solid-gas, liquid-gas, and solid-liquid phase transitions available in the literature were collected and combined with own exptl. results. We have evaluated and recommended the set of vaporisation and formation enthalpies of pyrazine derivatives at 298.15 K as the reliable benchmark properties for further thermochem. calculations Gas phase molar enthalpies of formation of pyrazine derivatives calculated by the high-level quantum-chem. method G4 were in agreement with the recommended exptl. data. Compilation of exptl. and theor. results derived in this work is useful for optimization of hydrogenation/dehydrogenation reactions involved in the hydrogen storage technologies.
