| 摘要 |
The invention concerns a process and an apparatus for the manufacture of aqueous solutions of alkali metal hypochlorite. The apparatus comprises a reaction vessel in which chlorine is caused to react with a solution of alkali metal hydroxide and a control device adapted so as to regulate the relative weights of chlorine and alkali metal hydroxide for the reaction, as a function of the derivative, with respect to time, of the redox potential of the reaction, modulated by an instantaneous value of this potential.
