Description
Yeriahren zur Herstellung einer löslichen Cadmiumverbindung. Im Hauptpatent ist ein Verfahren be schrieben, nach dem man eine Komplexver bindung von Antimon mit Pyrogalloldisulfo- säure erhält. Verbindungen dieser Art unter scheiden sich von gewöhnlichen Salzen des Antimons dadurch, dass sie eine Reihe von Reaktionen dieser Salze nicht haben. Sie enthalten nämlich das Antimon in festerer sogenannter Komplexverbindung. Diese Stoffe sind als Heilmittel verwendbar, da in ihnen infolge der festeren Bindung des Antimons die schädliche Wirkung gegenüber der Heil wirkung zurückgedrängt ist.
Es wurde gefunden, dass die gleichen Verhältnisse obwalten, wenn man brenzkate- chindisulfosaures Kalium mit Cadmiumhydro- xyd umsetzt.
Die Ausführung des Verfahrens erfolgt am besten in der Weise, dass man brenzkate- chindisulfosaures Kalium mit der erforder lichen Menge der Cadmiumverbindung in wässeriger Lösung, 'gegebenenfalls unter Er wärmen umsetzt.
<I>Beispiel:</I> In einer heissen Lösung von 35 gr brenz- katechindisulfosaurem Kalium wird soviel Cadmiumhydroxyd gelöst, als zur Erzielung einer neutralen oder nahezu neutralen Lösung erforderlich ist. Man filtriert und fällt nach dem Abkühlen das gebildete Komplexsalz durch Zugabe eines organischen Lösungs mittels als flockigem Niederschlag aus. Das erhaltene Produkt stellt ein farbloses bis schwach gelb gefärbtes, in 'Wasser leicht lösliches Pulver dar. Es dient als Mittel gegen Infektionskrankheiten.
Zur Herstellung des Cadmiumkomplex- salzes kann man auch von Cadmiumcarbonat ausgehen. Dabei entsteht wahrscheinlich als Zwischenprodukt Cadmiumhydroxyd.
Yeriahren for the production of a soluble cadmium compound. The main patent describes a process according to which a complex compound of antimony with pyrogallol disulfonic acid is obtained. Compounds of this type differ from ordinary salts of antimony in that they do not have a number of reactions of these salts. They contain the antimony in a more 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 healing effect.
It has been found that the same conditions prevail when potassium catechol disulphonate is reacted with cadmium hydroxide.
The method is best carried out in such a way that potassium catechol disulphonate is reacted with the required amount of the cadmium compound in an aqueous solution, if necessary with heating.
<I> Example: </I> In a hot solution of 35 g of pyrocatechol disulphonate, as much cadmium hydroxide is 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 slightly yellow colored powder which is easily soluble in water. It is used as an agent against infectious diseases.
Cadmium carbonate can also be used as a starting point for the production of the cadmium complex salt. This probably creates cadmium hydroxide as an intermediate product.
