Abstract
A method of isolating and purifying a product of sugar alcohol or anhydrosugar alcohol hydrogenolysis from a reaction mixture containing sorbitans, 1,2,4-butanetriol (BTO), 1,2,5,6-hexanetetrol (HTO), among other byproducts of a hydrogenolysis reaction of a sugar alcohol and/or a mono- or di-dehydrative product of a sugar alcohol is described. The method involves contacting the mixture having the products of sugar alcohol or anhydrosugar alcohol hydrogenation and other C-Calcohols and polyols with a resin material adapted for chromatography under conditions where the products preferentially associates with the resin relative to other components in the mixture, and eluting products from the resin with a solvent. The method suggests a way for separation of aliphatic polyols generated from the hydrogenolysis of sugar alcohols or anhydrosugar alcohols.
