Thus, we integrated the following physicochemical properties of the solute: melting point (T m ), standard enthalpy of vaporization (∆H v ), and standard Gibbs free energy of solvation in an infinitely dilute CO 2 solution (∆G solv ). Their physical meanings are as follows: the melting point relates to the enthalpy of melting via the Clausius-Clapeyron equation, with substances having higher melting points generally exhibiting lower solubility, as more energy is required to break their crystal lattice; enthalpy of vaporization characterizes the energy required for the phase transition from liquid to gas; and Gibbs free energy of solvation reflects the interactions between solvent and solute molecules, with higher absolute values typically indicating a greater tendency for the compound to dissolve in CO 2 .
