CA 2202624

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.

L'invention concerne un procédé pour produire une solution aqueuse d'oxyde d'amine utilisée dans le procédé à l'oxyde d'amine pour produire une solution de cellulose moulable. Dans ce procédé, des solutions aqueuses contenant de l'oxyde d'amine, apparaissant lors du procédé à l'oxyde d'amine, notamment sous forme de bains de régénération, sont purifiées et concentrées, un agent microbicide étant ajouté aux solutions aqueuses contenant de l'oxyde d'amine avant, pendant ou après la purification.
