Description
Verfahren zur Darstellung von Alkalisalzen der Cyanmercuriphenole Man hat die Alkalisalze der Cyanmercuriphenole in der Weise hergestellt, daß man die Salze der Mercuriphenole, beispielsweise Mercuriphenolsulfat, durch Kochen mit Cyanalkalien zur Umsetzung brachte und die erhaltenen freien Cyanmercuriphenole in Alkalien löste, oder auch dadurch, daß. man Phenolalkalien mit Quecksilberoxyd und Cyanalkalien oder mit Quecksilbferoxydcyanid erhitzte, die erhaltenen Lösungen durch Eindampfen konzentrierte und sie von den verunreinigenden Salzen durch. Kristallisation trennte. Die Darstellung der reinen Verbindungen war, weil beim Eindampfen meist stark gefärbte zersetzte Produkte entstehen, schwer durchführbar.Process for the preparation of alkali salts of cyano mercury phenols The alkali salts of the cyano mercury phenols have been prepared in such a way that the salts of the mercuriphenols, for example mercuriphenol sulfate, by boiling with Cyanalkali brought to implementation and the resulting free cyano mercury phenols dissolved in alkalis, or by the fact that. one phenolic alkalis with mercury oxide and alkali cyano or heated with mercury oxide, the solutions obtained concentrated by evaporation and removing the contaminating salts. Crystallization separated. The representation of the pure compounds was mostly because of the evaporation strongly colored decomposed products arise, difficult to carry out.
Es wurde die Beobachtung gemacht, daß sich die freien Phenylenquecksilberoxyde der Formel die sich wegen ihrer Unlöslichkeit in Wasser leicht völlig frei von anorganischen Salzen erhalten lassen, schon in der Kälte in feuchtem Zustande durch Cyanalkalien zu Alkalisalzen der Cyanmercuriphenole lösen, so daß man die Alkalisalze der Cyanmercuriphenole in völlig reinem Zustande ohne Beimengungen anderer Salze oder auch von Zersetzungsprodukten erhalten kann. Man kann die Umsetzung in der Kälte in so konzentrierter Form, d. h. mit so wenig Wasser vornehmen, daß das Eind'ampfed gegenüber den bisher üblichen Verfahren, bei welchen sehr verdünnte Lösungen entstehen, sich auf ein Mindestmaß herabsetzen läßt.It was observed that the free phenylene mercury oxides of the formula which, because of their insolubility in water, can easily be kept completely free of inorganic salts, dissolve in the cold in a moist state by means of cyano alkalis to form alkali salts of the cyano mercury phenols, so that the alkali salts of the cyano mercury phenols can be obtained in a completely pure state without the addition of other salts or decomposition products. The cold reaction can be carried out in such a concentrated form, that is to say with so little water, that the evaporation can be reduced to a minimum compared to the previously customary processes in which very dilute solutions are formed.
Die auf diese Weise erhaltenen reinen Alkalisalze der Cyanmercuriphenole sind farblose, in Wasser klar lösliche Verbindungen, welche in verdünnten Lösungen außerordentlich stark schäumen und somit ein hohes Benetzungsvermögen aufweisen, Sie zeigen stark bakterizide und fimgizide Eigenschaften und sollen als Desinfektionsmittel Anwendung finden. Beispiele r. 292 g o-Phenylenquecksilberoxyd (z Mol.) CGH4 # Hg # O (Dimroth Ber. 32 [i899], Seite 76q.) werden noch feucht in eine Lösung von 5o g (z Mol.) Cyannatrium in zooo g Wasser eingetragen. Die klare, - schwach gelbliche Lösung wird im Vakuum eingedampft. Das erhaltene Salz ist in Wasser klar löslich; durch verdünnte Säure entsteht eine weiße Fällung von Cyanmercuriphenol. Es besitzt die Formel Der Quecksilbergehalt beträgt 59 °/o. Die Ausbeute ist nahezu die theoretische. 2.292 g o-Phenylenquecksilberoxyd werden in der Kälte in eine Lösung von 65 g Cyankalium in -rooo ä Wasser eingetragen.. Die entstandene _ fast farblose--Lösung wird im Vakuum zur Trockne gebracht. Das erhaltene Salz besitzt die Formel: Der Quecksilbergehalt beträgt 50 %. Kohlensäure oder verdünnte Mineralsäuren erzeugen weiße Niederschläge von Cyanmercuriphenol.The pure alkali metal salts of the cyano mercuric phenols obtained in this way are colorless compounds which are clearly soluble in water, which foam extremely strongly in dilute solutions and thus have a high wetting power. They show strong bactericidal and fimgicidal properties and are intended to be used as disinfectants. Examples r. 292 g of o-phenylene mercury oxide (z mol.) CGH4 # Hg # O (Dimroth Ber. 32 [1899], page 76q.) Are added while still moist to a solution of 50 g (z mol.) Of cyan sodium in zooo g of water. The clear, pale yellowish solution is evaporated in vacuo. The salt obtained is clearly soluble in water; a white precipitate of cyano-mercuric phenol is produced by dilute acid. It has the formula The mercury content is 59 per cent. The yield is almost the theoretical. 2.292 g of o-phenylene mercury oxide are introduced in the cold into a solution of 65 g of potassium cyanide in -rooo ä water. The resulting _ almost colorless - solution is brought to dryness in a vacuum. The salt obtained has the formula: The mercury content is 50%. Carbonic acid or dilute mineral acids produce white precipitates of cyano mercuriphenol.
