Abstract

Method of manufacturing chlorine dioxide which is essentially free of chlorine byproduct. Chlorine dioxide is manufactured from alkali metal chlorate, a mineral acid and a reducing agent, such as methanol, in a reaction medium which maintains an acid normality of less than 9 and a high chlorate molarity. The method is carried out essentially without chloride ions being supplied to the process. It has been found that increasing the chlorate concentration at a given acid normality decreases the quantity of chloride in the reaction medium thereby decreasing the quantity of chlorine byproduct. The method is carried out in a vessel at negative pressure in which water is vaporized and removed together with chlorine dioxide and alkali metal salt of the mineral acid is crystallized in the reaction vessel and removed therefrom. According to the invention, it is possible to achieve a high rate of production together with a high degree of efficiency without any significant quantity of chlorine byproduct being produced.
