Abstract

The invention relates to a process for the preparation of concentrated alkali metal hypochlorite solutions in which chlorine and the alkali metal hydroxide are injected into a vertical receptacle, the bottom part of which has a cross-section less than the cross-section of its top part. This receptacle is equipped with an external hypochlorite recycling loop.
