Description
Verfahren zur Darstellung eines neuen schwefel- und stickstoffhaltigen Kondensations produktes aus dein Einwirkungsprodukt von Chlorschwefel auf a-Naphtylamin. Wird das im Schweizer Patent Nr. 92581 beschriebene Einwirkungsprodukt von Chlor schwefel auf a-Naphthylamin mit p-Amino- phenylarsinsäure kondensiert, so entsteht eine neue Verbindung von wahrscheinlich folgender Zusammensetzung:
EMI0001.0007
Diese Verbindung besitzt wertvolle therapeu tische Eigenschaften. Sie soll zur Herstel lung von Farbstoffen und pharmazeutischen Produkten benutzt werden.
Beispiel: 7 kg des Einwirkungsproduktes von Chlorschwefel auf a-Naphthylamin werden mit etwa 40 kg Eisessig angerührt; hierzu gibt man bei gewöhnlicher Temperatur eine Lösung von 5,5 kg p-Aminophenylarsinsäure und 6,8 kg Natriumacetat (kristallisiert) in etwa 10 Liter Wasser. Nach mehrstündigem Rühren bei gewöhnlicher Temperatur wird die Reaktion durch Erwärmen auf 60 bis 70 C zu Ende geführt. Durch Zugabe von Salzwasser wird das Kondensationsprodukt völlig abgeschieden.
Zur Reinigung wird es in heisser etwa 30 % Essigsäure gelöst, zu dieser Lösung etwa die Hälfte des Volumens Doppeltnormal-Salzwasser zugefügt und aus kristallisieren gelassen. Man erhält so die neue Verbindung in feinen ziegelrot gefärb ten Nädelchen. Die Alka.lisalze. sind gelbrot gefärbt und leicht wasserlöslich. Alkalische Reduktionsmittel spalten die neue Verbindung zu einem Merkaptan von wahrscheinlich folgender Konstitution:

Process for the preparation of a new sulfur- and nitrogen-containing condensation product from your product of action of chlorosulphur on a-naphthylamine. If the action product of chlorine sulfur on a-naphthylamine, described in Swiss patent no. 92581, is condensed with p-aminophenylarsinic acid, a new compound is formed, probably with the following composition:
EMI0001.0007
This compound has valuable therapeutic properties. It is intended to be used to manufacture dyes and pharmaceutical products.
Example: 7 kg of the product of the action of sulfur chloride on a-naphthylamine are mixed with about 40 kg of glacial acetic acid; a solution of 5.5 kg of p-aminophenylarsinic acid and 6.8 kg of sodium acetate (crystallized) in about 10 liters of water is added to this at normal temperature. After several hours of stirring at ordinary temperature, the reaction is brought to an end by heating to 60 to 70.degree. The condensation product is completely separated out by adding salt water.
To clean it, it is dissolved in about 30% hot acetic acid, about half the volume of double normal salt water is added to this solution and allowed to crystallize. The new compound is thus obtained in fine brick-red colored needles. The Alka.li salts. are colored yellow-red and easily soluble in water. Alkaline reducing agents cleave the new compound to a mercaptan of probably the following constitution:
