Läfst man auf Nitrosodimethylanilin in salzsaurer Lösung Sulfocarbonsäure einwirken, so tritt ein Molekül der letzteren mit drei Molekülen Nitrosodimethylanilin derart in Reaction, dafs der Sauerstoff der Nitrosogruppen mit je einem Atom Schwefel der Sulfocarbonsäure seinen Platz austauscht.If sulfocarboxylic acid is allowed to act on nitrosodimethylaniline in a hydrochloric acid solution, so if one molecule of the latter reacts with three molecules of nitrosodimethylaniline in such a way that that the oxygen of the nitroso groups with one atom of sulfur each of the sulfocarboxylic acid exchanges its place.

Behandelt man die Lösung des auf diese Weise aus demNitiOsodimethylanilin entstandenen Productes, nachdem sie mit Chlorzink und Kochsalz versetzt ist, mit einem Oxydationsmittel, so scheidet sich ein blauer Farbstoff in Flocken ab, Während ein rother,, schwefelhaltiger Farbstoff in Lösung bleibt. Behandelt man die Lösung des letzteren mit einem Reductionsmittel, z. B. Zink und Salzsäure, bis zur Entfärbung, so scheidet sich nach erneutem Zufügen eines Oxydationsmittels wieder blauer Farbstoff ab.If the solution of the resulting from the NitiOsodimethylanilin in this way is treated Productes, after being mixed with zinc chloride and table salt, with an oxidizing agent, so a blue dye is deposited in flakes, while a red, sulfur-containing dye remains in solution. If the solution of the latter is treated with a reducing agent, z. B. zinc and hydrochloric acid, until discoloration, then separates after adding another one The oxidizing agent removes the blue dye again.
Die Bildung des blauen Farbstoffes findet hierbei auch statt nach dem Verjagen des Schwefelwasserstoffes, von dem etwas bei der Reduction mit Zink und Salzsäure frei wird.The formation of the blue dye also takes place after the Hydrogen sulphide, some of which is released on reduction with zinc and hydrochloric acid.
Bei der Ausführung des Verfahrens fügt man zu einer Lösung von 15 Theilen Nitrosodimethylanilin in 40 Theilen Salzsäure und 300 Theilen Wasser unter Umrühren eine zehnprocentige Lösung irgend eines sulfocarbonsauren Salzes so lange hinzu, bis die Flüssigkeit, welche sich vorübergehend rosa färbt, wieder farblos geworden ist. Die farblose Flüssigkeit versetzt man darauf mit 15 Theilen Chlorzink und 100 Theilen Kochsalz und fügt irgend ein leicht Sauerstoff abgebendes Oxydationsmittel hinzu, und zwar so lange, bis die vom entstandenen Niederschlag abfiltrirte rothe Lösung auf Zusatz neuen Oxydationsmittels keine blaue Fällung mehr zeigt.In carrying out the procedure, nitrosodimethylaniline is added to a solution of 15 parts in 40 parts hydrochloric acid and 300 parts water with stirring a ten percent Solution of any sulfocarboxylic acid salt added until the liquid, which is temporarily turns pink, has become colorless again. The colorless liquid is added 15 parts of zinc chloride and 100 parts of table salt are then added, and anything is added easily Oxygen-releasing oxidizing agent added until the resulting Red solution filtered off precipitate on addition of new oxidizing agent no blue precipitate shows more.
Die vom blauen Farbstoff getrennte rothe Flüssigkeit wird bis zur Entfärbung mit Zink behandelt und darauf wie vorher oxydirt.The red liquid separated from the blue dye becomes with zinc until it is discolored treated and then oxidized as before.
Statt des Nitrosodimethylanilins kann man die Nitrosoverbindung irgend eines tertiären aromatischen Amins oder eines tertiären Orthoamins eines Phenoläthers anwenden. Die Sulfocarbonsäure oder deren Salze kann man durch die Aether der Sulfocarbonsäure ersetzen.Instead of nitrosodimethylaniline one can use any tertiary nitroso compound use aromatic amine or a tertiary orthoamine of a phenolic ether. The sulfocarboxylic acid or their salts can be replaced by the ethers of sulfocarboxylic acid.
