Description

  

      Verfahren    zur     Verstellung    einer löslichen     Cadmiumverbindung.            Ini        Hauptpatent    ist ein Verfahren     be-          sc        hrieben,    nach dem man eine     Komplexver-          bindung    von Antimon mit     Pyrogallolclistilfo-          säure    erhält. Verbindungen dieser Art un  terscheiden sich 'von gewöhnlichen Salzen  des Antimons dadurch, dass sie eine Reihe  von Reaktionen dieser Salze nicht haben.

    Sie enthalten nämlich das Antimon in feste  rer sogenannter     Komplexverhindung.    Diese  Stoffe sind als Heilmittel verwendbar, da in  ihnen infolge der festeren Bindung des An  timons die schädliche Wirkung gegenüber  der Heilwirkung zurückgedrängt ist.    Es wurde gefunden,     dass    die gleichen  Verhältnisse obwalten, wenn man     brenzkate-          chindisulfosaures    Natrium mit Cadmium  hydroxyd umsetzt.  



  Die     Ausfiihrung    des Verfahrens erfolgt       -im        besten    in der Weise, dass man     brenzkate-          chindisulfosaures    Natrium mit der erforder  lichen Menge der     Cadmiirmverbindung    in  wässeriger Lösung, gegebenenfalls unter Er  wärmen, umsetzt,         Beispiel:       In einer heissen Lösung von 35     gr        brenz-          liatechindisulfosaurem    Natrium wird soviel       Cadmiu.mhydroxyd    gelöst, als zur Erzielung  einer neutralen oder nahezu neutralen Lö  sung erforderlich ist.

   Man filtriert und fällt  nach 'dem Abkühlen das gebildete Komplex  salz durch Zugabe eines organischen Lö  sungsmittels als flockigen Niederschlag aus.  Das erhaltene Produkt stellt ein farbloses bis  schwach gelb gefärbtes, in Wasser leicht lös  liches Pulver dar. Es dient als Mittel gegen       Inf        ektionskrankheiten.       Zur Herstellung eines     Cadmiumkomplex-          salzes    kann man auch von     Cadmiumcarbonat     ausgehen, wobei     Cadmiumhydroxyd    als Zwi  schenprodukt entsteht.



      Method for adjusting a soluble cadmium compound. In the main patent a process is described by which a complex compound of antimony with pyrogallolclistilfic acid is obtained. Compounds of this kind differ from ordinary salts of antimony in that they do not have a number of reactions of these salts.

    This is because they contain the antimony in a solid, so-called complex compound. These substances can be used as remedies, because in them, due to the stronger bond of the antimony, the harmful effect is suppressed compared to the medicinal effect. It was found that the same conditions prevail when sodium pyrocatechol disulphonate is reacted with cadmium hydroxide.



  The method is best carried out in such a way that sodium pyrocatechin disulphonic acid is reacted with the required amount of the cadmium chloride compound in aqueous solution, if necessary with heating, example: In a hot solution of 35 g pyrocatechinic sodium disulphonate as much Cadmiu.mhydroxyd dissolved as is necessary to achieve a neutral or almost neutral solution.

   It is filtered and, after cooling, the complex salt formed is precipitated as a flaky precipitate by adding an organic solvent. The product obtained is a colorless to pale yellow colored powder which is easily soluble in water. It is used as an agent against infectious diseases. To produce a cadmium complex salt, one can also start from cadmium carbonate, with cadmium hydroxide being an intermediate product.
