Abstract

Fremgangsmåte ved fremstilling av i hovedsak klorfri klordioksyd, idet en klordioksydstrøm erholdt fra reduksjon av alkalimetallklorat, inneholdende biproduk- ter av klorgass, absorberes i vann og klorgassen behandles i vannløsningen med maursyre ved tilsetning av denne til vannet eller vannlosningen, idet maursyretil- setningen gjøres utover et eventuelt forekommende maursyrebiprodukt fra klordioksydfremstillingen. Maursyren tilsettes i en mengde som gir et molforhold maursyre til klorgass > 1:1.
