Environmentally Benign Green Chemical Process
Non-traditional tunable solvents for sustainable chemical processes have been developed in our laboratories over the past decade. These include (1) supercritical fluids (CO2, ethane, etc.), (2) near critical water, (3) ionic liquids, (4) gas-expanded liquids (GXLs), (5) fluorous biphasic systems, and (6) organic-aqueous tunable systems (OATS). Examples of reactions and processes (substitutions, alkylations, etc.) employing each of these solvent systems will be presented along with mechanistic insights.
