PROCESS FOR THE PREPARATION OF GASEOUS HYPOCHLOROUS ACID AND APPLICATION TO THE PREPARATION OF HYPOCHLORITE FROM GRANULAR CALCIUM

摘要

THE INVENTION CONCERNS THE PREPARATION OF HYPOCHLOROUS ACID FROM CHLORINE GAS AND AN AQUEOUS SOLUTION OF AN ALKALINE HYDROXIDE. /P P THIS AQUEOUS SOLUTION IS REACTED IN THE STATE OF FINE-DIVIDED MIST WITH GASEOUS CL, AT A HIGH ENOUGH TEMPERATURE TO PREVENT CONDENSATION OF THE GASEOUS PRODUCT. THE GASEOUS HYPOCHLOROUS ACID OBTAINED IS SEPARATED, FROM ITS FORMATION, FROM THE RESULTING SOLID ALKALINE CHLORIDE; THEN THE ACID IS WASHED WITH WATER TO GIVE AN AQUEOUS SOLUTION OF HYPOCHLOROUS ACID. /P P APPLICATION: PRODUCTION OF CALCIUM HYPOCHLORITE BY REACTION OF THE SOLUTION WITH LIME.
