when chloric acid containing water is contacted with activated carbon under acidic conditions of low pH, chloric acid in the chloric acid containing water reacts with activated carbon as a strong oxidizing agent to efficiently adsorb the activated carbon, thereby increasing the activated carbon adsorpti...
acid where the chlorine atom is in the +1 oxidation state and has the formula HClO. It forms when Cl2dissolves in water. It cannot be isolated in pure form due to rapid equilibration with its precursor. Addition of chlorine to water gives both hydrochloric acid (HCl) and hypochlorous acid:...
A process for producing chlorine dioxide is provided which reacts an aqueous solution of chloric acid and an alkali metal chlorate with a solution of a non-oxidizable acid in the presence of an oxygen- evolving catalyst in a reaction zon... David W. Cawlfield,Sudhir K. Mendiratta,Jerry J...
The novel process of the invention produces chlorine dioxide by feeding an aqueous solution of chloric acid to a chlorine dioxide generator. The aqueous solution of chloric acid is reacted with a reducing agent in the chlorine dioxide generator to produce chlorine dioxide and a spent chloric acid...
chlorate ions are also oxidized at the anode forming perchlorate ions. These perchlorate ions as perchloric acid in the acidic solutions in a chlorine dioxide generator also can react with added reducing agents, but does not form chlorine dioxide. This formation of perchlorate ion creates an ineffic...
reacts as a strong oxidant particularly at a lowered pH; accordingly, if the chloric acid-containing water is brought into contact with the activated carbon under an acidic condition of low pH, the chloric acid contained in the chloric acid-containing water reacts as a strong oxidant with the...
Gaseous hypochlorous acid product is immediately separated from the resulting solid alkali metal chloride as it is formed and is then scrubbed with water to form an aqueous hypochlorous acid solution. This solution may be reacted with lime to produce calcium hypochlorite.BRENNAN JAMES PATRICK, US...

A process for producing chlorine dioxide is provided which reacts an aqueous solution of chloric acid and an alkali metal chlorate with a solution of a non-oxidizable acid in the presence of an oxygen- evolving catalyst in a reaction zone to produce a gaseous mixture of chlorine dioxide gas...
reactants or byproduct such as alkali sulfate as impurities is circulated and washed in a packed tower(1) with satd. hydrochloric acid(6,7) at ambient temp. or 50C, and dissolved in water. Aq. soln. of HCl is distd. again to evaporate HCl vapor absorbed again in water.YAMASHIDA ...
