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.

Abstract: Disclosed is a method for producing aminodihalophosphines, diaminohalophosphines, triaminophosphines, phosphite diamides, aminophosphines, diaminophosphines, phosphite amide halogenides, and aminophosphine halogenides by separating an acid in the presence of an auxiliary base. Said auxiliary base b) forms a salt with an acid, which is liquid at temperatures at which the valuable product is not significantly decomposed during separation of the liquid salt, and c) the salt of the auxiliary base and the valuable product or the solution of the valuable product form two immiscible phases in a suitable solvent.
