Recovery of Glycols from Aqueous Solutions

IntroductionGlycols, in particular ethylene glycol, are used as antifreeze in automobiles, are a main constituent of plastics such asf poly(ethylene terephthalate) or PET, polyesters, and polyurethanes. The combined utility of glycols represents a multibillion dollar market. These compounds are typically formed in multistep processes in dilute aqueous...

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...
