- Аннотация: The thermodynamic properties of new classes of compounds, particularly scandium trihalides ScF3, ScCl3, ScBr3, and ScI3, are added to the IVTANTHERMO software package. A critical analysis and processing of the entire array of primary data available in the literature is performed. An equation approximating the temperature dependence of heat capacity in the temperature range 298.15 − Tm (K) is derived for each crystalline scandium trihalide. The resulting equations for the solid state and the data for the liquid phase are used to calculate the thermodynamic functions of entropy, the reduced Gibbs free energies, and the enthalpy increments. Both the experimental data available in literature and the missing estimated thermodynamic data are used in calculations. The error of the recommended values is estimated in all cases. In the first part of this work, we describe the thermodynamic properties of ScF3 and ScI3 used as the reference data for calculating the thermodynamic functions of ScCl3 and ScBr3, for which experimental data are either very scarce or missing altogteher. The resulting data are added to the database of the IVTANTHERMO software package.
