M 136015 KLASSE 22 ö. M 136015 CLASS 22 ö.

Es hat sich gezeigt, dafs der in der Patentschrift 133686 beschriebene gelbe Farbstoff gleichfalls erhalten werden kann, wenn man ß- Amidoanthrachinon der Einwirkung von wasserfreiem Aluminiumchlorid unterwirft.It has been shown that the yellow dye described in patent 133686 can also be obtained if you ß-amidoanthraquinone of the action of subjected to anhydrous aluminum chloride.

Man verfährt z. B. in folgender Weise:One proceeds z. B. in the following way:

10 kg ß-Amidoanthrachinon werden mit 12 kg wasserfreiem, sublimirtem Aluminiumchlorid innig gemischt und in einem eisernen Kessel auf 250 bis 280 ° C. erhitzt. Man erhält eine dunkel gefärbte Schmelze, welche bald erstarrt, wodurch der Endpunkt der Reaction zu erkennen ist. Zur Entfernung von überschüssigem Aluminiumchlorid kocht man die erhaltene Masse nach dem Erkalten wiederholt mit salzsäurehaltigem Wasser aus.10 kg of ß-amidoanthraquinone with 12 kg anhydrous, sublimated aluminum chloride intimately mixed and placed in an iron kettle Heated from 250 to 280 ° C. A dark colored melt is obtained, which soon solidifies whereby the end point of the reaction can be recognized. For removing excess After cooling, the resulting mass is repeatedly boiled with aluminum chloride containing hydrochloric acid Water out.

Der so gewonnene Rohfarbstoff enthält den gelben Farbstoff der Patentschrift 133686 in Mischung mit Verunreinigungen, die z. B. dadurch beseitigt werden können, dafs man ihn in seine Hydroverbindung überführt.The crude dye obtained in this way contains the yellow dye of patent 133686 in Mixture with impurities such. B. can be eliminated by having it converted into its hydro compound.

Man verfährt z. B. wie folgt:One proceeds z. B. as follows:

10 kg der mit Wasser ausgekochten Schmelze werden mit 1000 1 Wasser verdünnt und auf 60 bis 800C. erwärmt; nun setzt man 20 kg Natronlauge 300B. und 150 kg Natriumhydrosulfitlösung io° B. hinzu und hält die Temperatur ι Stunde auf 60 bis 80 ° C. Der gelbe Farbstoff ist mit schön blauvioletter Farbe in Lösung gegangen. Man filtrirt und versetzt das Filtrat mit 30 kg Natronlauge 300B. und kühlt ab. Nach einigen Stunden scheidet sich das Natronsalz der Hydroverbindung in Form gut ausgebildeter Nädelchen aus. Man filtrirt und wäscht mit wenig verdünnter Natronlauge. Zur Ueberführung der Hydroverbindung in den Farbstoff kocht man sie mit Wasser unter Einblasen von Luft, wobei sich der Farbstoff in Form von gelben Nadeln ausscheidet.10 kg of the melt boiled out with water are diluted with 1000 1 of water and heated to 60 to 80 ° C .; 20 kg of sodium hydroxide solution 30 ° C. and 150 kg of sodium hydrosulfite solution are now added and the temperature is kept at 60 to 80 ° C. for 1 hour. The yellow dye has dissolved with a beautiful blue-violet color. Is filtered and the filtrate with 30 kg of sodium hydroxide solution 30 0 B. and cools. After a few hours, the sodium salt of the hydro-compound separates out in the form of well-developed needles. It is filtered and washed with a little dilute sodium hydroxide solution. To convert the hydro compound into the dye, it is boiled with water while blowing in air, the dye separating out in the form of yellow needles.

Der so erhaltene gelbe Farbstoff kann nach den bereits beschriebenen Verfahren zum Färben verwendet werden, auch kann er zum Drucken Verwendung finden.The yellow dye thus obtained can be used for dyeing by the processes already described can also be used for printing.
