La base auxiliar c) actúa simultáneamente como catalizador nucleófilo, y la sal de la base auxiliar tiene un punto de fusión por debajo de 160°C. En dicho procedimiento se usa una base, que es seleccionada de entre las fórmulas (a) a (r), en donde: R1, R2, R3, R4, R5 y R6 significan, independientemente, hidrógeno, alquilo C1-18, alquilo C2-18, arilo C6-12, cicloalquilo C5-12 eventualmente interrumpidos por uno o varios átomos de oxígeno y/o átomos de azufre y/o uno o varios grupos imino sustituidos o no sustituidos, o un heterociclo de 5 a 6 miembros que presenta átomos de oxígeno, nitrógeno y/o átomos de azufre, cuyos radicales mencionados pueden estar sustituidos en cada caso por grupos funcionales, arilo, alquilo, ariloxi, alquiloxi, halógeno, heteroátomos y/o heterocicleno.

Abstract: Solvent system based on molten ionic liquid for biopolymers in the form of carbohydrates, comprises optionally additives and a protic solvent or its mixture, and if the protic solvent is water alone, then this is present in the solvent system in an amount of more than about 5 wt.%. Independent claims are included for: (1) a method for the production of a solvent system comprising mixing the carbohydrates with the molten ionic liquid and the protic solvent and/or its mixture, until the carbohydrates are dissolved; (2) a method for the production of regenerated carbohydrates, preferably starch, cellulose and their derivatives using the solvent system, where the solvent system is precipitated, preferably wet spun in a coagulation medium, and contains a solvent, which does not dissolve the carbohydrates and is mixable with the molten ionic liquid; (3) a regenerated carbohydrates, preferably in the form of regenerated cellulose fibers obtained by the above method; and (4) spinnable fibers based on regenerated cellulose with a wet fibrillation grade of /~2.

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.
