Catalysis: A greener solution.

Reports on a multiphase catalysis system devised by scientists which eliminates the difficulty faced in separating out products and recycling the catalytic material. Findings that suggest supercritical carbon dioxide (CO[sub2]) has been found to be useful in multiphase catalysis; Details of the catalytic system which uses ethylene glycol and carbon dioxide; Two immiscible liquids on which the success of classical multiphase catalysis depends; Benefits of using a supercritical CO[sub2].
