Das     handelsübliche        pulverförmige    Cal  ciumhypochlorit besitzt den     Nachteil,    dass es  nicht     hinreichend        irrveränderlich    ist,     wodurch     seine     Dosierbarkeit        ungünstig        bceiniltil.it    wird.

   Die     Herstellung    der     Mischung    kann     zum     Beispiel in einfachster Weise     derart        erfolgen,          dass        inan        Calcitimliypoclilorit    mit     gereinigtem,     insbesondere von Chlormagnesium weitge  hend befreitem Kochsalz, beide in     trockenem.          feingemahlenem    Zustande in     solchem        V('rIi-ilt-          nis    miteinander mischt.

    Method <SEP> zai1i <SEP> make <SEP> durable <SEP> of <SEP> C'1llcinmliypoclilorit. The commercially available powdery calcium hypochlorite has the disadvantage that it is not sufficiently variable, which makes it difficult to dose it.

    The production of prel) bodies from calcium hypochlorite has been dispensed with up to now, because they often have the disadvantage of being sparingly soluble.



       It has now been found that by mixing the powdered dry calcium hypochlorite with dry, purified, in particular chloromagnesium-free table salt, an easily soluble product is obtained in which the calcium hypochlorite has a good shelf life.

   The preparation of the mixture can, for example, be carried out in the simplest manner in such a way that calcitimliypoclilorite is mixed with purified common salt, in particular from chlorine magnesium largely freed, both in dry. finely ground condition in such a V ('ri-iltnis mixed with one another.

   that 1 (10 parts of the mixed product contain at least 10 parts of effective chlorine. 1) a the mixing ratio is not tied to narrow limits, then within the practically possible limits Prodtiktc
