Description
Verfahren zur Darstellung von löslichen organischen Antimonverbindungen. Durch das Hauptpatent ist ein Verfahren geschützt, nach welchem man durch Einwirkung von Antimonoxyd oder Antimonhydroxyd auf Brenzcatechinsulfosäuren bzw. deren Salze Komplexverbindungen erhalten kann, deren Salze in Wasser löslich sind. Es wurde nun weiter gefunden, daß man analoge Komplexverbindungen erhalten kann, wenn man als Komplexbildner aromatische o-Dioxy verbindungen verwendet, die an Stelle der Sulfogruppe(n) Carboxylgruppen im Benzolkern substituiert enthalten.Process for the preparation of soluble organic antimony compounds. A process is protected by the main patent, after which one by action from antimony oxide or antimony hydroxide to catechol sulfonic acids or their salts Complex compounds can be obtained, the salts of which are soluble in water. It was now further found that analog complex compounds can be obtained if one aromatic o-dioxy compounds are used as complexing agents in place of the Sulpho group (s) contain substituted carboxyl groups in the benzene nucleus.
So läßt sich aus Protocatechusäure, wenn man die im Hauptpatent näher beschriebenen Arbeitsweisen anwendet, ein wasserlösliches Komplexsalz herstellen.This can be derived from protocatechuic acid, if one looks at the details in the main patent applies the procedures described, produce a water-soluble complex salt.
Die neuen Produkte zeichnen sich gleichfalls durch ihre günstige Heilwirkung aus.. Beispiel.The new products are also characterized by their beneficial healing properties from .. example.
Zu einer Lösung von 15,49 Protocatechusäure in i oo ccm Wasser und der äquivalenten Menge Natronlauge gibt man i o g Antimonoxyd und kocht einige Zeit unter gleichzeitiger Zufügung von so viel Natronlauge, daß die Reaktion am SChluß neutral oder nahezu neutral ist. Dann filtriert man vom ungelösten Antimonoxyd ab und dampft das Filtrat zur Trockne ein. Der Rückstand läßt sich zu einem schwach gefärbten Pulver verreiben, das leicht wieder in -\Vasser löslich ist. Die wäßrige Lösung gibt mit verdünnter Natronlauge keine Fällung.To a solution of 15.49 protocatechuic acid in 100 cc of water and To the equivalent amount of caustic soda, add 10 g of antimony oxide and boil for a while with the simultaneous addition of so much sodium hydroxide solution that the reaction at the end is neutral or nearly neutral. Then the undissolved antimony oxide is filtered off and evaporate the filtrate to dryness. The residue turns into a weak one Rub colored powder, which is easily soluble in water again. The watery one Solution does not precipitate with dilute sodium hydroxide solution.
Statt der Natronlauge können z. B. Kalilauge oder Ammoniak oder Amine zur Salzbildung verwendet werden.Instead of caustic soda, z. B. potassium hydroxide or ammonia or amines can be used for salt formation.
