  • METHOD FOR PRODUCING CELLULOSE ACETALS
    Publication number: 20090187016
    Abstract: The present invention describes a process for preparing acetals of polysaccharides, oligosaccharides or disaccharides by dissolving these in at least one ionic liquid and reacting them with a vinyl ether. The acetalated polysaccharides or oligosaccharides obtained in this way can be crosslinked by treatment with acid. The present invention also provides acetals of polysaccharides, oligosaccharides or disaccharides and also crosslinked polysaccharides or oligosaccharides.
    Type: Application

  • METHOD FOR ACYLATING CELLULOSE WITH A SPECIFIC AVERAGE DEGREE OF POLYMERIZATION
    Publication number: 20090182138
    Abstract: The present invention describes a process for acylating polysaccharides or oligosaccharides, which comprises dissolving a polysaccharide or oligosaccharide in at least one ionic liquid and, in step A) treating the solution with at least one acid, if appropriate with addition of water, (step A1) or, if appropriate with addition of water, at elevated temperature (step A2) and, in step B) reacting the polysaccharide or oligosaccharide obtained in this way, whose DP is lower than that of the polysaccharide or oligosaccharide used, with an acylating agent.
