Process for purifying aqueous solutions of tertiary amino oxides |
| abstract |
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 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) purifying the used precipitation bath by bringing it into contact with an ion exchanger, a purified, aqueous amino oxide solution being formed which is possibly dephlegmated and is then used in step (A) again for dissolving cellulose. The invention is characterized in that an ion exchanger is used whose carrier is cellulose to which groups suitable for ion exchange are attached. |
