AUTHOR provided an overview of catalysis in functionalized ionic liquids. For example, AUTHOR focused on supported ionic liquids used for hydrogenation and hydroformylation reactions.

IN THESE SYSTEMS, a monolayer of ionic liquid is covalently bound to the surface of a solid support, such as silica. Additional unbound ionic liquid is added, along with the catalyst that dissolves in the ionic liquid. The result is a free-flowing solid that is amenable to heterogeneous fixed-bed technology, which is favored by industry. Yet when the reactants are added, they dissolve in the ionic liquid layer as well, allowing homogeneous catalysis to occur. The low volume of ionic liquid that is needed, compared with a bulk solution, is additionally useful for a potential industrial process.
