Allitol hexaacetate

The dulcitol hexaacetate mother liquor yielded a small quantity of crystalline material, m. p. 50-59°, whose nature has not been determined. Its melting point is near that of allitol hexaacetate (m. p. 61-62°).w... 

Reference alditol acetates elute from the BPX-70 column in the following order erythritol triacetate, 2-deoxyribitol tetraacetate, rhamnitolpentaacetate, fucitolpentaacetate, ribitol pentaacetate, arabinitol pentaacetate, xylitol pentaacetate, 2-deoxyglucitol hexaacetate, allitol hexaacetate, mannitol hexaacetate, galactitol hexaacetate, glucitol hexaacetate, and rnyo-inositol hexaacetate. Their identification can be verified by using individual standards. 

The amount of each neutral monosaccharide in the samples can be calculated relative to the internal standard, allose, using response factors. The relative response of the detector for the individual alditol acetates can be calculated from the areas under the peaks for each alditol acetate, relative to the area under the peak for allitol acetate. There should be no peaks in the chromatogram of the water control and only one peak, corresponding to allitol hexaacetate from the internal standard allose, in the chromatogram of the TFA control.
