Den Gegenstand des vorliegenden Zusatz-Patentes ' bildet die Darstellung von gelben, mit Chromoxyd gebeizte Wolle licht- und seifenecht färbenden Farbstoffen durch Anwendung der im Haupt-Patente No. 56456 beschriebenen Reductionsmethode auf Azofarbstoffe, welche durch Paarung von diazotirten .Nitraminen mit Salicylsäure oder Kresotinsäuren entstehen.The subject of the present additional patent 'forms the representation of yellow, with Chromium oxide stained wool to dye light and soap fast by application in the main patent no. 56456 described reduction method on azo dyes, which by pairing diazotized nitramines with salicylic acid or cresotinic acids.
Beispiel I. Darstellung eines Azoxyfarbstoffes aus m-Nitranilin: .Example I. Preparation of an azoxy dye from m-nitroaniline:.
13,8 kg m-Nitranilin und 35,5 kg gewöhnliche Salzsäure werden mit 1 500 1 Wasser in Lösung gebracht und in die kalte Flüssigkeit 22,5 1 Natriumnitrit von 33 pCt. Reingehalt zugegossen. Nach erfolgter Reaction wird die Lösung des Diazokörpers mit 1000 1 salicylsaurem Natron, welche 13,8 kg reine Säure enthalten, gemischt und die Mischung sich selbst überlassen. Nach einigen Stunden werden 284 1 Natronlauge von 400B. und 16 kg Traubenzucker von 80 pCt. Reingehalt zugegeben. Nun wird die Flüssigkeit auf 40 bis 6o° C. erwärmt und so lange auf dieser Temperatur erhalten, bis eine herausgenommene Probe ungeheizte Wolle in saurem Bade nicht mehr anfärbt. Dieser Punkt wird in 4 bis 8 Stunden erreicht. Durch Ansäuren der Mischung mit Schwefel- oder Salzsäure wird der Farbstoff in unlöslicher Form gefällt. Er wird auf Filtern gesammelt, gewaschen, geprefst und mit 28 1 Natronlauge von 40° B. in wasserlösliches Natronsalz übergeführt, welches am besten in Form von Paste verbraucht wird.13.8 kg of m-nitroaniline and 35.5 kg of common hydrochloric acid are dissolved in 1,500 liters of water and 22.5 liters of 33 pCt sodium nitrite are added to the cold liquid. Poured in purity. After the reaction has taken place, the solution of the diazo body is mixed with 1000 liters of sodium salicylic acid, which contains 13.8 kg of pure acid, and the mixture is left to itself. After several hours, 284 1 of sodium hydroxide solution 40 0 B. and 16 kg of glucose by 80 are cent. Purity added. The liquid is now heated to 40 to 60 ° C. and kept at this temperature until a sample that has been removed no longer stains unheated wool in an acidic bath. This point is reached in 4 to 8 hours. Acidifying the mixture with sulfuric or hydrochloric acid precipitates the dye in insoluble form. It is collected on filters, washed, pressed and converted into water-soluble sodium salt with 28 l of 40 ° B. sodium hydroxide solution, which is best consumed in the form of paste.
Beispiel II. In Beispiel I wird das m-Nitranilin durch 15,2 kg m-Nitro-o-toluidin (Schmelzpunkt 107°) oder m-Nitro-p-toluidin (Schmelzpunkt 78°) oder durch die Mischung derselben ersetzt. Die Reduction wird so lange fortgesetzt, bis eine herausgenommene Probe nach Ausfärben auf mit Chromoxyd gebeizter Wolle die Abwesenheit des Nitrokörpers zu erkennen giebt.Example II. In Example I, the m-nitro-niline is replaced by 15.2 kg of m-nitro-o-toluidine (Melting point 107 °) or m-nitro-p-toluidine (Melting point 78 °) or replaced by the mixture thereof. The reduction will be like this continued for a long time until a sample was taken out after staining with chromium oxide stained wool reveals the absence of the nitro body.
Beispiel III. In Beispiel I und II wird die Salicylsäure durch 15,2 kg einer der Kresotinsäuren ersetzt und im übrigen wie in Beispiel I und II verfahren. Das Ende der Reduction wird durch Probefärben erkannt.Example III. In Examples I and II, the salicylic acid becomes one of the cresotinic acids with 15.2 kg replaced and otherwise proceed as in Examples I and II. The end of the reduction is recognized by test staining.
Der Azoxyfarbstoff theilt im allgemeinen der gebeizten Wolle eine grünlichere Nuance mit als der entsprechende nitrirte Azokörper.The azoxy dye generally gives the stained wool a greener shade than the corresponding nitrided azo body.
Alle diese Farbstoffe, die von einander wenig verschieden sind, besitzen die Eigenschaft, mit Chromoxyd gebeizte Wolle licht- und seifenecht gelb zu färben. Die Echtheit dieser Farben steht weder dem Indigoblau, noch dem Alizarinroth nach.All of these dyes, which are little different from one another, have the property of having To dye chromium oxide stained wool yellow, lightfast and soapfast. The authenticity of these colors is neither inferior to the indigo blue nor the alizarin red.
