Abstract
A method of isolating and purifying 1,2,5,6 hexanetetrol (HTO) from a reaction mixture containing HTO and other byproducts of a hydrogenation 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 comprising HTO and other C1-C6 alcohols and polyols with a resin material adapted for chromatography under conditions where HTO preferentially associates with the resin relative to other components in the mixture, and eluting HTO from said resin with a solvent.
