Method for producing and processing a cellulose solution

摘要

The invention relates to a method for producing and processing a cellulose solution which is obtained by dissolving the cellulose in a tertiary piperidonyl amine oxide, preferably piperidonyl NMMO. The cellulose dissolved in this manner is subsequently shaped, coagulated and the solvent is removed. The tertiary amine oxide in said method is N-methylmorpholine-N-oxide (NMO). The piperidonyl NMMOs are produced from aqueous NMMO and piperidone by the distillation of water. Temperatures of between 60 and 130 DEG C are preferably used during the production of the cellulose solution.
