A process for controlling the chlorate and hydrogen ion content of the reaction mixture in the manufacture of chlorine dioxide from alkali metal chlorate and inorganic acid, to improve the yield of chlorine dioxide and minimize side reactions. The concentration of chlorate ions and hydrogen ions in the reaction mixture is monitored calorimetrically, the addition to the system of chlorate, reducing agent and inorganic acid is controlled in a manner to maintain the chlorate and hydrogen ion concentrations thereof at a desired level. |
