Abstract: The present invention describes a method for producing acetals of poly-, oligo- or disaccharides by dissolving them in at least one ionic liquid and then reacting them with a vinylether. The resulting acetalized poly- or olig osaccharides can be cross-linked by treatment with acid. The present inventi on relates also to acetals of poly-, oligo- or disaccharides and cross-linke d poly- or oligosaccharides.

Abstract: Silylating poly-, oligo-, disaccharides or their derivatives comprises dissolving the poly-, oligo- disaccharides in an ionic liquid and reacting the obtained mixture with a silylating agent. An independent claim is included for a method for the acylation of silylated poly-, oligo- or disaccharides comprising dissolving the poly-, oligo- disaccharides in an ionic liquid, reacting the obtained mixture with a silylating agent and subsequently acylating the obtained mixture.

Abstract: Acetalation of di-, oligo- or polysaccharides (or their derivatives) (I) is carried out by dissolving (I) in at least one ionic liquid (II) and reacting with a vinyl ether (III). Independent claims are included for: (1) new cellulose acetals obtained by the process, where (III) is of formula (R' x)(R' y)C=CH-OR' z (III''); (2) the production of crosslinked cellulose, by dissolving (I) in (II), reacting with (III) and treating the product with acid; and (3) crosslinked cellulose obtained by the process. R' y1-30C alkyl, 2-30C alkenyl, 2-30C alkynyl, 3-12C cycloalkyl, 5-12C cycloalkenyl, aryl or heterocyclyl (all optionally substituted); R' x + R' z-(CH 2) o-(X) p-(CH 2) q (optionally substituted); X : O, S, SO, SO 2 or N(1-4C alkyl); o, q : 1-6; p : 0 or 1.
