Claims (6)
1. Förfarande för framställning av klordioxid, klor och alkalimetallsalt under växelvis användning av saltsyra och svavelsyra, eller blandningar därav, sora stark mineralsyra i samma reaktor, kännetecknat därav, att svavelsyra införes i en reaktor innehällande en vattenhaltig reak-tionslösning omfattande ett alkalimetallklorat, en alkalime-tallklorid och ett alkalimetallsulfat, varvid reaktionen ge-nomföres vid en syranormalitet inom intervallet cirka 2 tili 11 n i en reaktionslösning som kontinuerligt mättas med al-kalimetallkloriden och alkalimetallsulfatet, att svavelsyra-tillförseln tili reaktorn fortsättes för framställning av klordioxid, klor och ett alkalimetallsalt, att syratillför-seln växlas frän svavelsyra tili saltsyra och att saltsyra-tillförseln tili reaktorn fortsättes utan väsentlig ändring av reaktionsbetingelserna för framställning av klordioxid, klor och alkalimetallsalt.
2. Modifikation av förfarandet enligt krav 1, känne-t e c k n a d därav, att saltsyra först användes som reak-tant och att denna utbytes mot svavelsyra.
3. Förfarande enligt krav 1,kännetecknat därav, att tili lösningen, i vilken reaktionen äger rum, tillföres en katalytisk mängd av minst en katalysator vald bland vana-dinpentoxid, silverjon, manganjon, dikromatjon, palladiumjon och arsenikjon.
4. Förfarande enligt krav 1,kännetecknat därav, att reaktionen genomföres i ett enda kärl, som samtidigt utgör reaktionskärl, indunstare och kristallisationskärl.
5. Förfarande enligt krav 1, kännetecknat därav, att reaktionstemperaturen hälles mellan cirka 25-90°C och
