METHODS TO PREPARE CHLORINE ACID AND CHLORINE DIOXIDE. |
| abstract |
Chlorous acid is generated from a precursor chlorite salt, or a precursor chlorate salt. The ion exchange material facilitates the generation of chlorous acid by simultaneously removing undesirable cations from the solution and adding hydrogen ions to the solution. Chlorine dioxide is generated in a controlled manner from chlorous acid by catalysis. Chlorine dioxide can be generated either subsequently to the generation of chlorous acid or simultaneously with the generation of chlorous acid. By catalysing chlorous acid to chlorine dioxide, the chlorous acid can be generated by ionic exchange or in a conventional manner. Ion exchange materials are also used to purify chlorine acid and chlorine dioxide solutions, without causing degradation of the solutions, to exchange undesirable ions in chlorine acid and chlorine dioxide solutions, with desirable ions, such as stabilizing ions, and to adjust the pH of the solutions of chlorous acid and chlorine dioxide. |
