Metal-catalyzed cleavage of polyols (MCCP) is a novel technology for preparing low molecular weight polyols such as ethylene glycol and propylene glycol from high molecular weight polyols. Specifically, MCCP is a novel route for breaking apart these sugars (C6 and C5) using a metal-catalyzed, alkaline cleavage of sugar alcohols to C3 compounds. The technology possesses several advantages over existing methods. MCCP accelerates the cracking step, is able to utilize lower reaction temperatures, and has better selectivity. Thus, for example, it is able to produce lactic acid as desired. MCCP separates the usual hydrogenolysis process into two steps. It is through this novel process separation that MCCP has also shown enhanced yields of the desired products.
