Способ получения двуокиси хлора заключается в восстановлении хлората натрия метанолом в водной кислой реакционной среде при нормальности общей кислоты ниже 7N и реакционной среде, находящейся при температуре кипения, при этом прилагают к ней давление ниже атмосферного, а концентрация хлората в ней составляет по крайней мере примерно 2,0 М. В таких условиях реакция образования побочных продуктов в отсутствие иона хлорида исключается, а также исключается присутствие хлора в водном растворе двуокиси хлора.A method for producing chlorine dioxide is to reduce sodium chlorate with methanol in an aqueous acidic reaction medium with normal acid total below 7N and the reaction medium at boiling point, while applying a pressure below atmospheric and at least about 2 , 0 M. In such conditions, the reaction of formation of by-products in the absence of chloride ion is excluded, and the presence of chlorine in an aqueous solution of chlorine dioxide is also excluded.
