    摘要： Moulding material and spinning material respectively containing cellulose, an aqueous tertiary amine-oxide, a non-solvent and a stabiliser, characterised in that, one or more stabilisers are provided which altogether have a basic and antioxidant action with the proviso that the basic stabiliser is not phosphate. The moulding material and spinning material respectively according to the invention are thermally stabilised against a runaway of the decomposition reaction. The degradation of the cellulose and of the amine-oxide is also largely prevented.

    摘要： A process for the purification of aqueous solutions of amine-oxides, characterized in that said solutions are contacted with an aqueous purification solution of an alkali hydroxide and/or ion pair reagent by means of an anion active membrane. By means of the process according to the invention, an efficient separation, particularly of anions of lower carboxylic acids and inorganic acids, can be achieved.

    摘要： The invention is concerned with a process for the production of cellulose moulded bodies wherein a suspension of cellulose in an aqueous solution of a tertiary amine-oxide is transformed into a mouldable solution, said solution being extruded by means of a forming tool and conducted into a precipitation bath. The process is characterized in that at least part of the materials in devices and pipes for the transportation and processing of the solution, which material is in contact with the mouldable solution contains at a minimum of 90% up to a depth of at least 0,5 .mu.m, preferably more than 1 .mu.m, at least one element of the group consisting of titanium, zirconium, chromium and nickel in elementary form and/or in the form of compounds provided that the remaining of the material does not contain any of the elements of the group consisting of copper, molybdenum, tungsten or cobalt. By means of the use of certain elements and compounds according to the invention, it is possible to control the occurrence and the extent of exothermal degradation reactions in the cellulose solution.

    摘要： The invention is concerned with a process for the selective separation of morpholine from an aqueous solution containing morpholine, N-methylmorpholine and N-methylmorpholine-N-oxide, characterized by the following steps:(A) passing said aqueous solution over a cation exchanger capable of adsorbing morpholine in such an amount until it cannot be charged substantially with morpholine any more and an eluate substantially free from morpholine but containing N-methyhnorpholine and N-methylmorpholine-N-oxide is obtained, and(B) regenerating the cation exchanger charged with morpholine and reusing it in step (A).
