and they can vary between those exhibited by
gases to liquid-like values by small changes in
pressure and temperature [20]. For example,
supercritical fluids exhibit larger diffusivility
and lower viscosity than conventional liquids.
Consequently, interphase mass transfer
resistance is also lower relative to the liquid
solvent. On the other hand, substrates and
products that are sparingly soluble in the liquid
phase can become significantly more soluble in
supercritical fluids. Such unique and useful
properties of the fluids make them viable
solvent media for electrosynthesis.
