Abstract: Solution system (I) for biopolymers in the form of carbohydrates, based on molten ionic liquid, optionally containing additives, contains protic solvent(s) and, if the only protic solvent is water, in an amount more than about 5 wt.%. Independent claims are included for (1) process for producing (I); (2) process for producing regenerated carbohydrates using (I); (3) regenerated carbohydrate produced by this process, especially in the form of regenerated cellulose fibers.

Abstract: A process for the separation of acids from reaction mixtures by means of an auxiliary base (I) is characterized by (a) the base (I) forming a salt with the acid that is liquid at temperatures that do not lead to significant decomposition of the product during separation of the liquid salt (b) the salt of the base (I) forming two non-miscible phases with the product or solution of the product in a suitable solvent.
