Supercritical carbon dioxide (scCO2) is an alternative medium for sustainable chemistry [1] that is competitive in a variety of chemical processes of technological importance.[1, 2] Carbon dioxide has zero dipole moment and very low polarizability,[3] and most polarity studies describe scCO2 as a nonpolar medium with a very low dielectric constant and no hydrogen-bonding behavior, comparable to n-hexane or carbon tetrachloride.[3] These ...
