A water-soluble cellulose acetate sulfate (CAS) with a degree of acetylation (DS(Ac)) 2.4 and a degree of sulfation (DS(Sulf)) of 0.3 was obtained by direct acetylation of cellulose using sulfuric acid as catalyst. Using methylation analysis, IR and NMR spectroscopy, sulfate groups have been located on primary alcohol function of glucose residues. The(More)
