Abstract: Método para la producción de almidón regenerado, celulosa regenerada y derivados de almidón y de celulosaregenerados, empleando un sistema de solución que contiene almidón, celulosa y/o derivados de almidón ycelulosa, donde el sistema de solución está basado en un líquido iónico fundido y contiene un solvente prótico o unamezcla de varios solventes próticos, donde para el caso que el solvente prótico sea sólo agua, ésta está presente enel sistema de solución en una cantidad superior a 5 % en peso, y donde el sistema de solución contiene el solventeprótico, con excepción del agua, en una cantidad de por lo menos 0,1 % en peso, y el sistema de solución contienecomo solventes próticos metanol, etanol, 1-propanol, 2-propanol y/o 1-butanol, dado el caso en mezcla con agua,donde el sistema de solución es transformado en un medio de coagulación, en el cual se encuentra un solvente queno disuelve almidón, celulosa y/o derivados de almidón y celulosa y con el cual el líquido iónico fundido es miscible.

Abstract: A solution system for biopolymers in the form of carbohydrates based on a molten ionic liquid, additives optionally being contained in the solution system, is described. This solution system contains a protic solvent or a mixture of several protic solvents, and in the case where the protic solvent is solely water, this is present in the solution system in an amount of more than about 5 wt. %. Carbohydrates can be incorporated into the solution system, in particular in the form of starch, cellulose and derivatives thereof, and it can then be used for regeneration of the carbohydrates contained therein. A particularly advantageous process for the preparation of the solution system containing the carbohydrates and for the preparation of regenerated carbohydrates, in particular in the form of regenerated cellulose fibers, is moreover described. The invention accordingly also provides such spun fibers as are distinguished in that they are non-fibrillating. The invention offers in particular economic advantages over the systems of the prior art.

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.
