040081: Process for the Preparation of Lactic Acid and Glyceric Acid

Michigan State University’s invention is a process for making lactic and glyceric acid. Aqueous solutions of hexose and pentose sugars, typically glucose or fructose, are digested in the presence of strong anionic exchange resins that act as solid bases. Lactic and glyceric anions form but are bound to the ion exchange resins. The spent sugar solutions...

000013: Catalysts and Process for Hydrogenolysis of Sugar Alcohols to Polyols

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....

980061: Condensed Phase Catalytic Hydrogenation of Lactic Acid to Propylene Glycol

Propylene glycol is a nontoxic chemical used in polymers production, as a nontoxic antifreeze, and in food, drink, cosmetic, and pharmaceutical applications. Propylene glycol is currently made commercially by high pressure and high temperature hydrolysis of propylene oxide. Description Michigan State University’s invention provides a low-cost...
