Abstract

The chlorous acid reaction with hypochlorous acid (chlorine) may be responsible for the chlorine dioxide formation in a methanol based chlorine dioxide generation process. In this paper, the reaction between chlorous acid and hypochlorous acid in a 4.5 mol/L sulfuric acid solution was studied. It was found that chlorine dioxide is generated only if chloride is present. The underlying mechanism associated with the effect of chloride on the reaction was discussed.

Abstract

La réaction d'acide chloreux avec de l'acide hypochloreux (chlore) pourrait être responsable de la formation de bioxyde de chlore dans un procédé de production de bioxyde de chlore à base de methanol. Dans cet article, on a étudié la réaction entre l'acide chloreux et l'acide hypochloreux dans une solution d'acide sulfurique de 4,5 mol/L. On a trouvé que le dioxyde de chlore est produit seulement en présence de chlorure. Le mécanisme sous-jacent associé à l'effet du chlorure sur la réaction est examiné.
