Intermolecular interactions between CH3OCHX2 (X = H, F, Cl, Br, CH3) with carbon dioxide (CO2) and water (H2O) were theoretically investigated using high-level ab initio methods. The addition of an H2O molecule to the CH3OCHX2∙∙∙CO2 complex enhances the stability of ternary complexes. This finding supports the increase of solubility of CH3OCHX2 in supercritical CO2 with the presence of H2O.
