| titleOfInvention | Process of activating the oxidising power of chlorite solutions |
| abstract | Bleaching solutions comprising chlorites are activated by adding a metalloid of Group V or VI of the Mendelieff classification, or carbon, in finely-divided state and in quantity sufficient to acidify the solution by forming, at the expense of a small amount of the chlorite, the acid corresponding to the metalloid used, said acid then decomposing the chlorite and freeing chlorine dioxide. The metalloid may be freed in situ by the action of the chlorite on a compound adapted to generate the metalloid. Examples are given in which chlorite solutions are activated by adding red phosphorus, sodium thiosulphate, arsenic sulphide and ammonium and potassium thiocyanates. Other compounds mentioned capable of liberating the metalloid, are sulphur chlorides, sulphuryl chlorides and polysulphides.ALSO:Bleaching solutions comprising chlorites are activated by adding a metalloid of Group V or VI of the Mendelieff classification, or carbon, in finely-divided state and in quantity sufficient to acidify the solution by forming, at the expense of a small amount of the chlorite, the acid corresponding to the metalloid used, said acid then decomposing the chlorite and freeing chlorine dioxide.
