Claims (1)

Способ включает нагревание реакционной смеси, состоящей из водного раствора, содержащего перхлорат-ионы, хлорат-ионы и ионы водорода для получения диоксида хлора и газообразного кислорода. Предлагаемый способ обеспечивает процесс получения диоксида хлора из смесей кислородных соединений хлора в отсутствие восстановителя. Способ обеспечивает получение диоксида хлора, по существу не содержащего хлора без побочного продукта - кислой соли. Кроме того, способ позволяет снизить количество кислоты, подаваемой в реактор для получения диоксида хлора.The method includes heating the reaction mixture consisting of an aqueous solution containing perchlorate ions, chlorate ions and hydrogen ions to produce chlorine dioxide and gaseous oxygen. The proposed method provides a process for the production of chlorine dioxide from mixtures of oxygen compounds of chlorine in the absence of a reducing agent. The method provides for obtaining chlorine dioxide, which is essentially free of chlorine without a by-product, an acid salt. In addition, the method allows to reduce the amount of acid supplied to the reactor to produce chlorine dioxide.
