Abstract
Chlorine dioxide is produced in a continuous process by reaction of sodium chlorate and hydrochloric acid. The reaction medium is maintained at its boiling point under subatmospheric pressure and the resulting steam is used to dilute the chlorine dioxide and chlorine and remove the same from the reaction zone. Sodium chloride is deposited from the reaction medium in the reaction zone. The reaction medium also contains buffering anions and the actual hydrogen ion concentration of the reaction medium is maintained in the range of about 0.05 to 0.3 normal to maintain an economic production rate for the chlorine dioxide.
