    摘要: The present invention relates to a process for producing spherical particles of at least one material, which comprises the steps: (A) preparation of a solution or dispersion of the at least one material in at least one water-miscible solvent or dispersion medium, (B) conversion of the solution or dispersion obtained in step (A) into individual portions comprising an amount of the at least one material corresponding to the amount present in the spherical particles by underwater pelletization and (C) introduction of the portions obtained in step (B) into a medium which is miscible with the solvent or dispersion medium from step (A) and in which the material used in step (A) is insoluble so that the solvent or dispersion medium used in step (A) is replaced by the medium which is miscible with the solvent or dispersion medium from step (A) and the material solidifies to form the spherical particle.

    摘要: 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.
