PATENTAMT.PATENT OFFICE.
Das Verfahren besteht darin, dals die Diazoderivate der Metasulfanilsäure, der Parasulfanilsäure, der Ortho- und Paratoluidinsulfosäure mit a-Naphtylamin combinirt, darauf von neuem diazotirt und alsdann mit Metaphenylendiamin, Metatoluylendiamin oder Resorcin combinirt werden.The method consists in using the diazo derivatives metasulfanilic acid, parasulfanilic acid, ortho- and paratoluidinsulfonic acid combined with a-naphthylamine, then diazotized again and then with metaphenylenediamine, Metatoluylenediamine or resorcinol can be combined.
Die Art der Zubereitung ist für alle diese Producte dieselbe.The method of preparation is the same for all these products.
Beispiel: 10 kg metasulfanilsaures Natron (oder die entsprechende Menge des Natronsalzes einer anderen der oben genannten Sulfosäuren) werden in 200 1 Wasser und 13 kg Salzsäure von 200 B. gelöst und dieser Lösung alsdann unter Umrühren und Abkühlen eine Lösung von 3,4 kg salpetrigsaurem Natron in 10 1 Wasser hinzugesetzt. Die erhaltene Flüssigkeit enthält das Diazoderivat; man vermischt dieselbe mit einer Lösung von 4 kg salzsaurem a-Naphtylamin in 250 1 Wasser.For example (another one of the above sulfo acids or the corresponding amount of sodium salt) 10 kg metasulfanilsaures soda is dissolved in 200 1 of water and 13 kg of hydrochloric acid 20 0 B. and then this solution under stirring and cooling, a solution of 3.4 kg Nitrous acid sodium in 10 l of water was added. The liquid obtained contains the diazo derivative; it is mixed with a solution of 4 kg of hydrochloric acid a-naphthylamine in 250 l of water.
Sobald die Reaction beendet ist, filtrirt man; das gesammelte Product wird mit 500 1 Wasser verrührt und dieser Lösung 13 kg Salzsäure und hernach eine Lösung von 3,4 kg salpetrigsaurem Natron in 10 1 Wasser hinzugesetzt. Das Diazoderivat, welches sich niederschlägt, sammelt man auf dem Filter und schüttet es darauf in eine Lösung von 5,4 kg Metaphenylendiamin in 500 1 Wasser, wobei man eine hinreichende Menge kohlensauren Natrons zusetzt, damit die Flüssigkeit nach der Reaction schwach alkalisch bleibt. Schliefslich fällt man den Farbstoff durch Kochsalz.As soon as the reaction is over, it is filtered; the collected product is mixed with 500 l of water stirred and 13 kg of hydrochloric acid and then a solution of 3.4 kg of sodium hydroxide in 10 l of water were added to this solution. The diazo derivative that precipitates is collected on the filter and poured out then in a solution of 5.4 kg of metaphenylenediamine in 500 l of water, with a sufficient amount of carbonate of soda added so that the liquid remains slightly alkaline after the reaction. Eventually you fall the dye with table salt.
Man verfährt in derselben Weise, wenn man das Metaphenylendiamin durch die äquivalente Menge Metatoluylendiamin oder Resorcin ersetzt.The procedure is the same if the metaphenylenediamine is replaced by the equivalent Amount of metatolylenediamine or resorcinol replaced.
Die vom Resorcin herrührenden Farbstoffe sind rothviolett, alle übrigen schwarzviolett.The dyes originating from resorcinol are red-violet, all the rest are black-violet.
Alle diese Farbstoffe besitzen unter anderen Eigenschaften diejenige, Baumwolle im alkalischen Bade, Wolle und Seide im neutralen, alkalischen oder sauren Bade zu färben und mit den allgemein in der Färberei angewendeten verschiedenen Beizen oder Salzen lebhafter zu werden.All of these dyes have, among other properties, that of cotton in the alkaline state To dye bath, wool and silk in neutral, alkaline or acid baths and with those generally used in dyeing different pickles or salts to become livelier.
Die angegebenen Verhältnifszahlen der Reagentien können verändert werden.The stated ratios of the reagents can be changed.
