Abstract
Chlorine dioxide is formed by reduction of sodium chlorate in a sulphuric acid-containing reaction medium. Sulphuric acid is introduced to the reaction medium in air atomized form to promote rapid and efficient mixing of the sulphuric acid, thereby avoiding chlorine dioxide decomposition at hot spots resulting from inefficient mixing of acid with the reaction medium.
