ABSTRACT:
Process and plant for the preparation of concentrated aqueous solutions of alkali metal hypochlorite, in which a suspension of crystals of alkali metal chloride in an aqueous solution of alkali metal hypochlorite is circulated from bottom to top in a tubular reaction chamber located in an enclosure, chlorine and an aqueous solution of alkali metal hydroxide are reacted in this suspension in the chamber, a fraction of the resulting suspension leaving the open upper part of the chamber, overflows out of the enclosure and is filtered to separate the crystals, and the remaining fraction of the suspension is kept in the enclosure where it is recycled to the base of the reaction chamber.
