Verfahren zur Darstellung roter chromierbarer Farbstoffe.Process for the preparation of red chromable dyes.
Patentiert im Deutschen Reiche vom 17. April 1908 abPatented in the German Empire on April 17, 1908
Durch Einwirkung der Diazoverbindungen von Aminoazobenzolsulfosäure und ihren Homologen auf Salicylsäure erhält man orange färbende Chromierungsfarbstoffe. Es wurde nun gefunden, daß durch Einführung der Oxyalkylgruppe in den die Aminogruppe tragenden Kern der Aminoazobenzol- und -toluolsulfosäuren Nuance und Eigenschaften der Farbstoffe erheblich verändert und wertvolle rote ίο Farbstoffe erhalten werden. Die Färbungen zeichnen sich durch sehr gute Säure-, Walk-, Dekatur- und Lichtechtheit aus.By the action of the diazo compounds of aminoazobenzenesulfonic acid and its homologues on salicylic acid, chromating dyes that turn orange are obtained. It was now found that by introducing the oxyalkyl group into those bearing the amino group Core of the aminoazobenzene and toluene sulfonic acids Nuance and properties of the dyes significantly changed and valuable red ίο dyes are preserved. The colorations are characterized by very good acid, milled, decatur and light fastness.
Man diazotiert in der üblichen Weise 39 kg Natriumsulfanilat mit 58 kg Salzsäure 21 ° Be. und 14 kg Nitrit in 500 1 Wasser bei einer Temperatur von 50C. Nach Verlauf einer Stunde wird die Lösung von 29 kg m-Aminop-kresoläther in 25 kg Salzsäure und 1000 1 Wasser hinzugefügt. Nach 6 Stunden ist bei einer Temperatur von etwa 10 ° C. die Aminoazosulfosäure gebildet. Man fügt 46 kg Salzsäure und 17 kg Nitrit hinzu und rührt, bis die Diazotierung vollendet ist, was 5 bis 10 Stunden in Anspruch nimmt. Man filtriert die kristallisierte Diazoverbindung ab und trägt sie nach und nach während einer Dauer von etwa 3 Stunden in eine Lösung von 34 kg o-Kresotinsäure und 35 kg Natronlauge 350 Be. und 40 kg Soda in 1000 1 Wasser bei einer Temperatur von 15 ° C. ein. Sobald die Bildung des Farbstoffs vollendet ist, erwärmt man auf 75 ° C, fällt mittels Kochsalz, filtriert und trocknet.39 kg of sodium sulfanilate are diazotized in the customary manner with 58 kg of hydrochloric acid at 21 ° Be. and 14 kg of added nitrite in 500 1 water at a temperature of 0 5 C. After the lapse of one hour is added to the solution of 29 kg m-Aminop-kresoläther in 25 kg of hydrochloric acid and 1000 1 of water. After 6 hours at a temperature of about 10 ° C., the aminoazosulfonic acid is formed. 46 kg of hydrochloric acid and 17 kg of nitrite are added and the mixture is stirred until the diazotization is complete, which takes 5 to 10 hours. Is filtered off the crystallized diazo compound and transmits it gradually over a period of about 3 hours in a solution of 34 kg of o-cresotinic acid and 35 kg of sodium hydroxide 35 0 Be. and 40 kg of soda in 1000 l of water at a temperature of 15 ° C. As soon as the formation of the dye is complete, the mixture is heated to 75 ° C., precipitated using common salt, filtered and dried.
In trocknen} Zustand stellt der Farbstoff ein rotes Pulver dar, das in Wasser sehr löslich ist. Er färbt die Wolle direkt dunkelgelb. Durch Behandlung mit Chromkali schlägt die Farbe in dunkelrot um. An Stelle der Sulfanilsäure können die Isomeren, Analogen und Homologen dieser Säure verwendet werden, an Stelle der o-Kresotinsäure die Salicylsäure oder m-Kresotinsäure, ohne daß das Resultat wesentlich beeinflußt wird.In the dry} state, the dye represents is a red powder that is very soluble in water. It directly dyes the wool dark yellow. By treatment with chromium potassium beats the color to dark red. Instead of sulfanilic acid, the isomers, analogs and homologues of this acid can be used, instead of o-cresotinic acid, salicylic acid or m-cresotinic acid without significantly affecting the result.
