A process for the preparation and separation of the pentoses, xylose and arabinose from mixtures of saccharides by forming acetals is described. D-xylose is a precursor to xylitol, a sweetener, and L-arabinose is a precursor to the drug intermediate (R)-3,4-dihydroxybutyric acid, carnitine and agrichemicals.
