Process for the preparation of polysaccharide derivatives |
| abstract |
Process for the esterification, etherification or silylation of polysaccharide or its derivatives by means of an esterification reagent, etherifying reagent or silylating reagent in the presence of an ionic liquid, wherein (a) the esterification, etherification or silylation of the polysaccharide or its derivatives is carried out under heterogeneous reaction conditions, (B) the amount of ionic liquid is 2 to 25 wt .-% based on the polysaccharide or its derivatives. and (c) the ionic liquid is selected from the group consisting of imidazolium compounds, pyridinium compounds and mixtures thereof. |
