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...

030023: Renewable, Low-Cost Polyols and Polyesters from Natural Oils

As petroleum usage continues to increase and reserves of petroleum continue to be depleted, polymer manufacturers seek alternative methods for making useful materials currently derived from petroleum raw materials. Because of a personal desire to help understand and exploit 'green' technologies, the inventor of this technology has been studying...

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....
