Abstract: A process for preparing mono- or poly-C1-C20-alkyl- and/or -halogen-substituted arylcarbonyl chlorides (I), by, in a first stage, reacting a mono- or poly-C1-C20-alkyl- and/or -halogen-substituted aromatic (II) with CCl4 in the presence of a Friedel-Crafts catalyst to give the corresponding mono- or poly-C1-C20-alkyl- and/or -halogen-substituted trichloromethylated aromatic (III), and, in a second stage, treating the trichloromethylated aromatic (III) with water or a protic acid in the presence of a catalyst to obtain the arylcarbonyl chloride (I). In a particularly preferred embodiment, the trichloromethylated aromatic (III) is not isolated as an intermediate and is used in the second stage dissolved in the solvent of the first stage.

Abstract: Method for producing tertiary phosphines by reacting a compound of the general formula (I) in which A is R 1 or L 2 , B is R 2 or L 3 , the R 1 and R 2 radicals are each independently an organic radical having in each case from 1 to 30 carbon atoms, where the R 1 and R 2 radicals may also be joined together; and the leaving groups L 1 to L 3 are each independently halogen, alkyloxy having from 1 to 10 carbon atoms or aryloxy having from 6 to 10 carbon atoms (a) with an alkali metal in an organic aprotic solvent and (b) a compound of the general formula (II) L 4 -R 3 (II) in which the R 3 radical is an organic radical having in each case from 1 to 30 carbon atoms; and the leaving group L 4 is halogen, alkyloxy having from 1 to 10 carbon atoms or aryloxy having from 6 to 10 carbon atoms, in which the resulting reaction mixture is hydrolyzed with an aqueous base which has a pH of >= 10 and the organic phase is removed from the aqueous phase.

Abstract: A solvent system for biopolymers in the form of carbohydrates which is based on a molten ionic liquid, with additives being present in the solvent system if appropriate, is described. This solvent system comprises a protic solvent or a mixture of a plurality of protic solvents, and if the protic solvent is water alone, this is present in the solvent system in an amount of more than about 5% by weight. Carbohydrates can be incorporated into the solvent system, in particular in the form of starch, cellulose and derivatives thereof, and the solvent system can then be employed for regenerating the carbohydrates dissolved therein. In addition, a particularly advantageous method of producing the solvent system containing the carbohydrates and for producing regenerated carbohydrates, in particular in the form of regenerated cellulose fibres, is described. The invention accordingly also provides such spinning fibres which are nonfibrillating. The invention offers, in particular, economic advantages over the systems of the prior art.
