Interpretive Summary:

Technical Abstract: The attachment of monosaccharides to cellulose through esterfication with citrate-linked esters has been investigated to facilitate preparation of cotton modifications that are amenable to aqueous textile finishing approaches. The citrate-linked, monosaccharide cellulose conjugates have been formed through an acid-catalyzed reaction of the monosaccharide on cotton gauze and have shown valuable applications with a variety of hydroxylated substrates. Attempts to characterize the citrate-linked monosaccharide conjugates with traditional spectroscopic approaches were found unsatisfactory and characterization of the conjugates was attempted using a High Performance Liquid Chromatography (HPLC) approach. Analyses of both aldohexose and ketohexose monosaccharides were completed by applying the monosaccharide ester hydrolysis products to an anion exchange column (CarboPacTM PA1 analytical column with guard column) interfaced with amperometric detection. The HPLC co-elution of the products with monosaccharide standards revealed the principle products of the hydrolysis reaction to be the monosaccharide isomer of the hydrolyzed ester. The HPLC method was further developed for quantitative determination of the monosaccharide ester incorporated in the cotton fiber.
