Condensed Phase Catalytic Hydrogenation of Lactic Acid to
Propylene Glycol
Introduction
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 of TechnologyMichigan State University’s invention...

Catalysts and Process for Hydrogenolysis of Sugar Alcohols to Polyols
Description of TechnologyMetal-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...

Process for the Preparation of Lactic Acid and Glyceric Acid
Description of TechnologyMichigan 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...

High Yield Glycerol to
Propylene Glycol
Conversion Process
IntroductionThe increased production of biodiesel has resulted in a concomitant increased availability of glycerol, a byproduct of the production process. As a result the price of glycerol has experienced a sharp downward spiral. Challenges have confronted biodiesel producers who have pursued Glycerol conversion to the
Propylene Glycol
, a more desirable...
