Description
Verfahren- zur Darstellung eines als Farbstoff und Farbstoffzwischenprodukt verwendbaren ltondensationsproduktes der Anthrachinonreihe. Es wurde gefunden, dass man ein neues;
als Farbstoff und Farbstoffzwischenprodukt verwendbares Kondensationsprodukt der An thrachinonreihe erhält, wenn man Cyanur- chlorid mit einem Diaminoanthrachinonge- misch, wie es durch Dinitrieren von Anthra- ,chinon und nachfolgende Reduktion des Ni trierungsproduktes dargestellt werden kann, und sai$ 4-Amino-2.1-anthrachinonakridon, sowie 1-Aminoanthra:
chinon im ungefähren Verhältnis von 2 Molekülen Cyanurchlorid auf 1 Molekül Diaminoanthrachinon, 1 Mo lekül Aminoanthrachinonakriclon und 1 bis 2 Moleküle 1-Aminoanthra,chinon zur Umset zung bringt.
Beispieb: 24 Teile Diaminoanthrachinon, erhalten durch Dinitrierung von Anthrachinon und Reduktion des- dabei entstandenen Dinitroan- thrachinongemisches, werden in zirka 250 Teilen Nitrobenzol auf etwa<B>110'</B> C erwärmt und nach Zugabe einer 60 bis<B>80'</B> warmen Lösung von 40 Teilen Cyanurchlörid in 150 Teilen Nitrobenzol unter Rühren während ungefähr einer Stunde auf 140 bis 145' C erhitzt.
Darnach wird abgekühlt und das aus- geschiedene Produkt abfiltriert. Das erhal tene Produkt wird nun in etwa 800 Teilen Nitrobenzol aufgeschwemmt und nach Zusatz von 34 Teilen 4-Amino-2. 1-Anthra-chinon- akridon und 22,3 Teilen 1-Aminoanthra.- chinon mit diesen unter Rühren während 6 Stunden zum Sieden,des. Nitrobenzols erhitzt.
Nach Erkalten wird abgenuts.cht und das so gewonnene Produkt mit Nitrobenzol und' mit Sprit gewaschen und darauf getrocknet. Es ist ein dunkelgrünes Pulver, unlöelieU in Wasser und Alkohol, schwer löslich in hei- ssem. Nitrobenzol mit schmutzig-grüner Farbe. Seine Lösung in kalter konzentrierter Schwe felsäure ist rötlichbraün. Es liefert eine braunrote Küpe, aus der Baumwolle in gelb stichig oliven Tönen angefärbt werden kann.
An Stelle der durch Dinitrierung von An thrachinon und nachfolgende Reduktion ge wonnenen Diaminoverbindung, welche be kanntlich in der Hauptsache .aus einem Ge misch von 1.-5- und 1. 8-Diaminoanthrachi- non besteht, lässt sich in obigem Beispiel auch eine Mischung der auf anderem Wege separat erhaltenen, reinen 1 . 5= und 1 . 8-Diamino- verbindungen verwenden.
Process for the preparation of an oxidation product of the anthraquinone series which can be used as a dye and a dye intermediate. It was found that you can get a new one;
Condensation product of the anthraquinone series that can be used as dye and dye intermediate is obtained if cyanuric chloride is obtained with a diaminoanthraquinone mixture, as can be prepared by dinitrating anthraquinone and subsequent reduction of the nitration product, and sai $ 4-amino-2.1- anthraquinone acridone and 1-aminoanthra:
quinone in an approximate ratio of 2 molecules of cyanuric chloride to 1 molecule of diaminoanthraquinone, 1 molecule of aminoanthraquinone acriclone and 1 to 2 molecules of 1-aminoanthraquinone.
Example: 24 parts of diaminoanthraquinone, obtained by dinitrating anthraquinone and reducing the resulting dinitroanthrachinone mixture, are heated in about 250 parts of nitrobenzene to about 110 ° C and, after adding a 60 to 80 '</B> Warm solution of 40 parts of cyanuric chloride in 150 parts of nitrobenzene heated to 140 to 145 ° C for about one hour with stirring.
It is then cooled and the precipitated product is filtered off. The product obtained is now suspended in about 800 parts of nitrobenzene and after adding 34 parts of 4-amino-2. 1-Anthra-quinone akridon and 22.3 parts of 1-Aminoanthra.- quinone with these while stirring for 6 hours to the boil, des. Heated nitrobenzene.
After cooling, it is abgenuts.cht and the product obtained in this way is washed with nitrobenzene and fuel and then dried. It is a dark green powder, insoluble in water and alcohol, hardly soluble in hot. Nitrobenzene with a dirty green color. Its solution in cold concentrated sulfuric acid is reddish brown. It delivers a brown-red vat from which cotton can be dyed in yellow, olive tones.
Instead of the diamino compound obtained by dinitration of anthraquinone and subsequent reduction, which is known to mainly consist of a mixture of 1-5 and 1,8-diaminoanthraquinone, a mixture can also be used in the above example the pure 1. 5 = and 1. Use 8 diamino compounds.
