Supported liquid film catalyst and biphasic catalysis using water soluble metal complexes in a medium of supercritical carbon dioxide

摘要

Two phase catalysis involving water-scCO_2 and supported liquid film catalysis in scCO_2 medium provides environmentally benign alternative to the use of conventional homogeneous catalysis in practice, providing easy catalyst-product separation and eliminating use of hazardous organic solvents. The concept has been demonstrated for the hydrogenation of cinnamaldehyde.
