Thermal and sublimation properties of cardiovascular drugs sotalol and ivabradine hydrochlorides
The saturated vapor pressure of sotalol and ivabradine hydrochlorides was measured in the temperature range (413.15–437.15) K by the transpiration method. The sublimation thermodynamic functions (Gibbs energy, enthalpy and entropy) of the compounds were calculated from the temperature dependencies of saturated vapor pressure. The standard molar enthalpy of sublimation for sotalol and ivabradine hydrochlorides is (157.5 ± 1.4) kJ·mol−1 and (143.2 ± 1.2) kJ·mol−1, respectively. The thermal properties and crystal state of the drugs were studied by the DSC, TG/DTG and X-ray diffraction methods.
期刊介绍:
The Journal of Chemical Thermodynamics exists primarily for dissemination of significant new knowledge in experimental equilibrium thermodynamics and transport properties of chemical systems. The defining attributes of The Journal are the quality and relevance of the papers published.
The Journal publishes work relating to gases, liquids, solids, polymers, mixtures, solutions and interfaces. Studies on systems with variability, such as biological or bio-based materials, gas hydrates, among others, will also be considered provided these are well characterized and reproducible where possible. Experimental methods should be described in sufficient detail to allow critical assessment of the accuracy claimed.
Authors are encouraged to provide physical or chemical interpretations of the results. Articles can contain modelling sections providing representations of data or molecular insights into the properties or transformations studied. Theoretical papers on chemical thermodynamics using molecular theory or modelling are also considered.
The Journal welcomes review articles in the field of chemical thermodynamics but prospective authors should first consult one of the Editors concerning the suitability of the proposed review.
Contributions of a routine nature or reporting on uncharacterised materials are not accepted.
