While chlorine dioxide dissolved in water is stable (if kept cool and away from light), the gas will detonate at pressures above 300 Torr. To avoid formation of explosive concentrations of ClO2 above the solution, the concentration of chlorine dioxide must be kept below 5 g ClO2 per liter ...
there was the same outcry against its corrosive effects as arose when chlorine was substituted for crofting. A great advantage was found to result from the use of sulphuric acid, which was that a souring with sulphuric acid required at the longest only twenty-four hours, and often not more ...
During the normal first stage in a modern bleach plant, the unbleached pulp is chlorinated. Three to four percent of gaseouschlorineis rapidly mixed with pulp at a temperature of 21° to 27° C (70° to 80° F); the mixture is quite acid due to the acidity of the chlorine. Chlorine ...

Since an oxygen-base bleach has characteristic that it can be used for color-patterned materials, it has been the main stream of a bleach for clothes. On the other hand, the oxygen-base bleach is inferior in bleaching power in comparison with a chlorine-base bleach and thus, its improvement...
Such proposals have, however, involved the use of chlorine' dioxide in neutral or acid aqueous solutions. The success of processes based on this method of procedure has been limited due in part to the difficulty of causing sufficient C102 gas to dissolve in the aqueous solution. I have found...
Also, in a fixing solution typically containing thiosulfate, the introduction of a transition metal salt deteriorates the stability of the fixing solution to generate turbidity and sludge therein. As a result, the circulating flow amount is reduced due to clogging of the filter of an automatic dev...
