Abstract

The invention relates to a process for producing an aqueous amine oxide solution used in the amine oxide process for producing a mouldable cellulose solution, in which aqueous amine oxide-containing solutions occurring in the amine oxide process especially as regenerating baths are purified and concentrated, where a microbicidal agent is added to the aqueous amine oxide-containing solutions before, during or after purification.
