Description
Verfahren zur Herstellung einer löslichen Kupferverbindung. 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 festere Bindung des Antimons die schädliche Wirkung gegenüber der Heil wirkung zurückgedrängt ist.
Es wurde gefunden, dass die gleichen Verhältnisse obwalten, wenn man brenzkate- chindisulfosaares Kalium mit Kupferhydroxyd in Gegenwart von Kali umsetzt.
Die Ausführung des Verfahrens erfolgt am besten in der Weise, dass man brenz- katechindisulfosaures Kalium mit der erfor derlichen Kupferverbindung in wässriger Lö sung, gegebenenfalls unter Erwärmen umsetzt, wobei man nach Bedarf Kali zusetzt. <I>Beispiel</I> 35 gr brenzkatechindisulfosaures Kalium werden in 200 cm" Wasser gelöst und in die heisse Lösung eine aus Kupfervitriol durch Ausfällen mit Natronlauge, Absaugen, Aus waschen und Anrühren mit Wasser herge stellte Suspension von Kupferhydroxyd solange zugegeben, als sie sich noch löst.
Gleichzeitig wird verdünnte Kalilauge zugegeben in dem Masse, dass die Reaktion am Schluss ganz oder nahzu neutral ist. Man filtriert und kann das gebildete Komplexsalz aus der dunkel grünen Lösung durch Ausfällen mit einem organischen Lösungsmittel oder durch Ein dampfen gewinnen.
Process for producing a soluble copper 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 binding 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 disulphosate is reacted with copper hydroxide in the presence of potash.
The process is best carried out in such a way that potassium catechol disulphonate is reacted with the necessary copper compound in an aqueous solution, optionally with heating, with potassium being added as required. <I> Example </I> 35 grams of pyrocatechol disulphonic acid potassium are dissolved in 200 cm "of water and a suspension of copper hydroxide prepared from vitriol by precipitation with sodium hydroxide solution, suction, washing and stirring with water is added to the hot solution for as long as it is still dissolves.
At the same time, dilute potassium hydroxide solution is added to the extent that the final reaction is completely or almost neutral. It is filtered and the complex salt formed can be obtained from the dark green solution by precipitation with an organic solvent or by evaporation.
