Description
Verfahren zur Darstellung von Auromercapto-p-phenylendiamin Die bisher dargestellten Auromercaptoverbindungen hatten als Grundsubstanzen Verbindungen, die durch saure Eigenschaften ausgezeichnet waren. Es hat sich nun gezeigt, daß es gelingt, auch Auromercaptoverbindungen herzustellen, deren Trägermolekül ausgesprochen basischen Charakter besitzt.Process for the preparation of Auromercapto-p-phenylenediamine The hitherto Auromercapto compounds shown had compounds as basic substances, which were distinguished by acidic properties. It has now been shown that it is also possible to produce auromercapto compounds whose carrier molecule is pronounced has a basic character.
Es war nicht vorauszusehen, wie sich Aurisalze gegenüber solchen Verbindungen, wie p-Phenylendiaminmercaptan, verhalten würden, da ja Phenylendiamine oxydierenden Mitteln gegenüber recht empfindlich sind.It was impossible to foresee how auris salts would react to such compounds, like p-phenylenediamine mercaptan, since phenylenediamines are oxidizing Are quite sensitive to agents.
Das Auroinercapto-p-phenylendiamin soll als Desinfektionsmittel Verwendung finden. Beispiel I I Teile p-Phenylendiaminmercaptanchlorhydrat (erhalten aus p-Phenylendiaminthiosulfonsäure, Ann. 25t (i889], Seite 64, durch Reduktion mit Zinn und Salzsäure und Zerlegen des erhaltenen Zinnsalzes mit Schwefelwasserstoff] werden in zoo Teilen Wasser gelöst und allmählich r 5o Teile einer r oprozentigen Kaliumgoldbromidlösung zugefügt. Die gelbbraune Lösung wird sodann mit Natronlauge neutralisiert und das abgeschiedene gelb gefärbte Auromercapto-p-phenylendiamin mit Wasser und Alkohol gewaschen. Der Goldgehalt beträgt 57 °/o. Das salzsaure Salz ist ein in Wasser lösliches gelbgrün gefärbtes Pulver mit einem Goldgehalt von 46 %.The Auroinercapto-p-phenylenediamine is said to be used as a disinfectant. EXAMPLE II Parts of p-phenylenediamine mercaptan chlorohydrate (obtained from p-phenylenediamine thiosulfonic acid, Ann. 25t (1889), page 64, by reduction with tin and hydrochloric acid and decomposition of the tin salt obtained with hydrogen sulfide] are dissolved in zoo parts of water and gradually r 50 parts of an approx The yellow-brown solution is then neutralized with sodium hydroxide solution and the deposited yellow-colored Auromercapto-p-phenylenediamine is washed with water and alcohol. The gold content is 57%. The hydrochloric acid salt is a water-soluble yellow-green colored powder with a gold content of 46 % .
