Description

Verfahren zur Darstellung leicht löslicher komplexer Doppelsalze der Cyanmercuriphenole Um die unlöslichen Cyanmercuriphenole in wasserlösliche Verbindungen überzuführen, hat man sie durch Behandeln mit Ätzall.:alien in ihre Alkalisalze übergeführt. Es hat sich gezeigt, daß die freien Cyanmercuriphenole befähigt sind, sich mit Cyanalkalien zu Doppelsalzen zu vereinigen, welche in Wasser sehr leicht löslich sind. Man braucht beispielsweise nur CyanmercLiriphenole in wäßriger Suspension mit Cyankalium zu behandeln, um sofort ein in Wasser leicht lösliches Doppelsalz zu erhalten. Die Lösung ist sehr beständig, sie läßt sich ohne Zersetzung eindampfen, wobei sich die Doppelverbindung als festes beständiges Salz ausscheidet.Process for the preparation of easily soluble complex double salts of the cyano mercuriphenols In order to convert the insoluble cyano mercuriphenols into water-soluble compounds, they have been converted into their alkali salts by treating them with caustic.: Alien. It has been shown that the free cyano mercury phenols are able to combine with cyano alkalis to form double salts which are very easily soluble in water. For example, one only needs to treat cyano mer / diphenols in aqueous suspension with potassium cyan in order to immediately obtain a double salt which is readily soluble in water. The solution is very stable, it can be evaporated without decomposition, whereby the double compound precipitates as solid, stable salt.

Das Doppelsalz wirkt in sehr verdünnter Lösung stark schäumend wie Seife, hat ein außerordentlich großes Benutzungsvermögen. welches die fungicide Wirkung des Doppelsalzes stark unterstützt. Durch Kohlensäure wird das Doppelsalz kaum zersetzt, verdünnte Säuren fällen daraus die freien Cyanmercuriphenole. Die Verbindung soll als Saatgutbeize Verwendung finden.The double salt has a strong foaming effect in a very dilute solution Soap is extremely useful. which is the fungicide Effect of the double salt strongly supported. Carbon dioxide makes the double salt Hardly decomposed, diluted acids precipitate the free cyano-mercuriphenols from them. the Compound is said to be used as a seed dressing.

Beispiele 1. 3,03 kg (i Mol.) Cyanmercuriphenol werden mit einer Lösung von o,5 kg (i Mol.) Cyannatrium in i o 1 Wasser bei Zimmertemperatur behandelt. Das Cyanmercuriphenol geht nach kurzer Zeit in Lösung. Die farblose Lösung wird im Vakuum zur Trockne gebracht. Man erhält ein farbloses, in Wasser leicht lösliches, kristallines Salz in einer Ausbeute von 3,5 kg. Die wäßrige Lösung dieses Salzes wird im Gegensatz zu den Alkalisalzen der Cyanmercuriphenole durch Kohlensäure nicht gefällt; verdünnte Mineralsäuren scheiden unter Zersetzung des Doppelsalzes Cyanmercuriphenol als farblosen Niederschlag aus. Der Quecksilbergehalt des bei 90° getrockneten Salzes beträgt 55 0/0- 2. 3,07 kg Cyanmercuriphenol werden in eine Lösung von o,65 kg Cyankalium in i o 1 Wasser bei Zimmertemperatur unter Rühren eingetragen. Die Lösung wird im Vakuum zur Trockne gebracht; Ausbeute 3,5 kg. Man erhält ein farbloses, klar kristallines Salz, leicht löslich in Wasser. Die Lösung gibt mit Kohlensäure, Bicarbonaten oder Natriumchlorid keine Fällung. Quecksilbergehalt des bei 9o° getrockneten Salzes 52 %.EXAMPLES 1. 3.03 kg (i mol.) Of cyano mercuriphenol are treated with a solution of 0.5 kg (i mol.) Of sodium cyanide in 10 l of water at room temperature. The cyano-mercuriphenol dissolves after a short time. The colorless solution is brought to dryness in vacuo. A colorless crystalline salt which is readily soluble in water is obtained in a yield of 3.5 kg. The aqueous solution of this salt, in contrast to the alkali salts of the cyano mercuriphenols, is not precipitated by carbonic acid; Dilute mineral acids separate out as a colorless precipitate with decomposition of the double salt cyano mercuriphenol. The mercury content of the salt dried at 90.degree. C. is 55 0/0-2 . 3.07 kg of cyanomercuriphenol are introduced into a solution of 0.65 kg of potassium cyanide in 10 l of water at room temperature with stirring. The solution is brought to dryness in vacuo; Yield 3.5 kg. A colorless, clear crystalline salt is obtained, easily soluble in water. The solution does not precipitate with carbonic acid, bicarbonates or sodium chloride. Mercury content of the salt dried at 90 ° 52%.
