Process for production of chlorine dioxide

摘要

The present invention relates to aprocess for productionof chlorine dioxide comprising: reacting in an acidic reaction mediumin a reaction vessel an alkali metal chlorate or chloric acid and methanol to generate chlorine dioxide,withdrawingfrom the reaction vessel a gas comprising chlorine dioxideand gaseous by-products,condensing part of the gas withdrawn to obtain a condensate; and removing thecondensate from the non- condensed gas without re-circulating it back to the process for production of chlorine dioxide.
