Abstract
En fremgangsmåte for fremstilling av et alkallmetall- klorat ved elektrolyse l en membrancelle (3) av en anolytt omfattende en alkalimetallkloridoppløsnlng og av en katolytt omfattende en alkalimetallhydroksyd- oppløsning, idet alkallmetallkloridoppløsnlngen på forhånd renses ved den følgende sekvens av trinn: elektrolyse l en celle av "kloralkall"-typen (l) av en alkalimetallkloridoppløsning for, på den ene side, å danne gassformig klor og, på den annen side, en konsentrert alkalimetallhydroksydoppløsnlng, overføring av det gassformige klor og av alkall- metallhydroksydoppløsningen som fremstilles, til en "knockouf-kolonne (2) for å bringe dem til omsetning med hverandre, og gjenvinning av den således oppnådde saltoppløsning for å benytte den som anolytt i membrancellen (3). Oppfinnelsen angår også en Innretning for gjennomføring av denne fremgangsmåte og en Innretning for rensing av alkal imetallkloridoppløsning.A process for preparing an alkali metal chlorate by electrolysis in a membrane cell (3) of an anolyte comprising an alkali metal chloride solution and of a catholyte comprising an alkali metal hydroxide solution, the alkali metal chloride solution being purified in advance by the following sequence of steps: "Chlorine Alkal" type (1) of an alkali metal chloride solution to form, on the one hand, gaseous chlorine and, on the other hand, a concentrated Alkali metal hydroxide solution, transfer of the gaseous chlorine and of the Alkal metal hydroxide solution produced Column (2) for reacting with each other, and recovering the salt solution thus obtained to use it as anolyte in the membrane cell (3). imetallkloridoppløsning.
