Abstract

On produit le dioxyde de chlore de manière très économique en réduisant du chlorate de sodium à l'aide de méthanol dans un milieu réactionnel acide et aqueux et à une normalité d'acidité totale inférieure à 7, le milieu réactionnel étant à son point d'ébullition pendant qu'on lui applique une pression subatmosphérique, et présentant une concentration de chlore d'au moins environ 2,0 molaire. Sous ces conditions, la susceptibilité de la réaction aux arrêts épisodiques de la production de chlore sans apport d'ions de chlorure est éliminée. On peut ainsi éliminer la teneur en chlore de la solution aqueuse de dioxyde de chlore provenant de cette source.
