The invention relates to a process for producing carbon fibers from cellulosic fibers, characterized in that cellulosic fibers, which contain a sulfonic acid salt of formula (I), wherein Rrepresents a hydrocarbon group and Krepresents a cation, are converted into carbon fibers.

Method for producing carbon fibers from cellulose fibers treated with sulfonic acid salts

The present invention relates to a process for preparing C-Clactams, in which a C-C-alkyl nitrite is reacted with a C-C-cycloalkane and is illuminated with a light-emitting diode during the reaction. This forms a C-C-cyclohexanone oxime which is then converted further to a C-Clactam; the C-Calcohol formed is recycled into the preparation of the C-C-alkyl nitrite.

Method for producing C4-C15 lactams

Use of a phosphorus compound of the formula (I) as flame retardant, where the definitions of the symbols in the formula (I) are as follows:

The present invention relates to a method for dehydrating a carbohydrate-comprising composition.

Method for dehydrating a carbohydrate-comprising

The present process purifies a salt CatX, where Catis any cation and Xis an organic anion having at least 6 carbon atoms. The salt is an impurity in a composition comprising a water-soluble salt (Cat)Y, where Yis an inorganic anion or an organic anion, different from X, with at most 10 carbon atoms. The process involves converting Xinto an acid HX by adding an acid (H)Z, forming two phases: an organic phase comprising HX and an aqueous phase comprising the water-soluble salts (Cat)Zand (Cat)Yor acids (H)Y. The organic phase is separated and the aqueous phase passes over a basic anion exchanger which binds Zand Yand liberates OH, giving an aqueous mixture comprising CatOH. The organic phase and the aqueous mixture are converted into CatXand HO, optionally with addition of further HX.
