摘要： The invention relates to a process for producing cellulose shaped bodies, said process comprising the following steps: (A) dissolving cellulose in an aqueous solution of a tertiary amino oxide, in particular N-methylmorpholine-N-oxide (NMMO), to form a cellulose solution which can be shaped; (B) shaping the cellulose solution and guiding the shaped cellulose solution into an aqueous precipitation bath in which the cellulose is precipitated, whereby a shaped body and a used precipitation bath are formed; (C) regenerating the used precipitation bath, a regenerated, aqueous amino oxide solution being formed which is used in step (A) again for dissolving cellulose. The invention is characterized in that in step (A) a regenerated, aqueous amino oxide solution is used which has a pH in a range whose upper and lower limits are defined, as a function of the tertiary amino oxide concentration, by the equation pH = - 0.0015 x A2 + 0.2816 x A + f, A being the tertiary amino oxide concentration in the aqueous solution, expressed in weight % of the aqueous solution, and satisfying the condition: 40 % ≤ A ≤ 86 %, and preferably ≤ 70 % A ≤ 80 %, and f having the value 1.00 for the upper limit and -1.80, and preferably -1.00, for the lower limit.

摘要： A process is disclosed for purifying a tertiary aminoxide aqueous solution that contains impurities that are in part dissolved and in part available in a non-dissolved, colloidal form. The process is characterised by the combination of the following steps: (A) the non-dissolved impurities in colloidal form are practically all removed from the aqueous solution; and (B) the aqueous solution obtained after step (A) is brought into contact with an ion exchanger.

摘要： The invention relates to a method for producing cellulosic fibers from solutions of the cellulose in an aqueous tertiary amine oxide. The extruded fibers are guided through a spinning bath and are then cut. The cut fibers are guided through several interconnected washing baths in the form of a fleece and dried. Fresh washing liquid is supplied to the last washing bath and guided up to the first washing bath in counterflow to the direction of transport of the non-woven fleece. The inventive process is characterized in that the pH of each of the washing baths is kept above 8.5.

摘要： The invention relates to a process for the selective separation of morpholine from an aqueous solution containing morpholine, N-methyl morpholine and N-methyl morpholine-N-oxide, in which (A) a quantity of the aqueous solution is taken through a cation exchanger capable of adsorbing morpholine until said exchanger can carry substantially no more morpholine and an eluate substantially free from morpholine but containing N-methyl morpholine and N-methyl morpholine-N-oxide is obtained, and (B) the cation exchanger charged with morpholine is regenerated and re-used in step (A).
