- Abstract:
- Xylan sulfates have been prepared under homogeneous reaction conditions in DMF/LiCl
applying SO3/pyridine and SO3/DMF. The degree of substitution (DSSulfate) of the products
obtained was determined by elemental analysis. DSSulfate reached values of up to 1.90 applying
a molar ratio of 3 mol sulfating agent per anhydroxylose
unit. The structure of the xylans and of
the xylan sulfates was studied in detail by oneand
two-dimensional NMR spectroscopy and
MALDI-TOF mass spectrometry.
