EXPERIMENTAL STUDIES OF THERMODYNAMIC PROPERTIES OF 3-(5-PHENYLPYRROL-2-YL)-PROPANOIC ACID

For the first time, an experimental determination of the main (basic) thermodynamic properties of 3-(5-phenylpyrrol-2-yl)-propanoic acid was carried out using differential thermal and thermogravimetric methods of analysis and combustion bomb calorimetry. The values of the enthalpy of sublimation at 298 K and the enthalpy of formation in the gaseous state were calculated using the values of the enthalpies of vaporization and fusion, which were recalculated to 298 K, and the enthalpy of formation in the condensed state. The applicability of the Domalsky additive method for calculating the enthalpies of formation in the condensed and gaseous states is shown. Thermodynamic parameters will be crucial in the development of technological processes for the synthesis, purification, use, storage and transportation of 3-(5-phenylpyrrol-2-yl)-propanoic acid, as this compound exhibit biological activity, evidenced by the preliminary assessment of the molecule structure using the web-based program SuperPred, and will have potential use in the production of medicines.
