Description
Verfahren zur Darstellung eines wertvollen Küpenfarbstoffes. Im Hauptpatent ist ein Verfahren zur Darstellung eines wertvollen Küpenfarbstoffes beschrieben, bei dem Aminodibenzanthron, das erhalten werden kann durch Reduktion des durch Nitrieren von Dibenzanthron ent stehenden Mononitrodibenzanthrons, mit einem in 1-Stellung negativ substituierten Anthra- chinon kondensiert wird.
Es wurde nun gefunden, dass man einen ähnlichen wertvollen Küpenfarbstoff erhält, wenn man Aminodibenzanthron, das erhalten werden kann durch Reduktion des durch Nitrie ren von Dibenzanthron entstehenden Mononitro- dibenzanthrons, mit einem in 1-5-Stellung negativ substituierten Anthrachinon konden siert. Die Kondensation führt man zweck mässig in hochsiedenden Lösungs- oder Ver dünnungsmitteln aus, und man kann hierbei auch säurebindende Mittel zusetzen.
Vielfach ist die Anwendung von Katalysatoren vor teilhaft, als welche beispielsweise Gemische von Natriumacetat und Kupfersalzen benutzt werden können.
Der neue Küpenfarbstoff ist ein schwarzes Pulver; er ist in konzentrierter Schwefelsäure mit violetter Farbe löslich und färbt Baum wolle aus blauer Küpe in grauen bis schwarzen, hervorragend echten Tönen. Beispiel: Man suspendiert 94 Teile des Aminodi- benzanthrons in 1000 Teilen Nitrobenzol, gibt 30 Teile Natriumacetat, 7 Teile Kupfer oxyd und 28 Teile 1.5-Dichloranthrachinon zu, worauf man unter Rühren so lange kocht, bis das entstandene Reaktionsprodukt prak tisch halogenfrei ist. Man arbeitet sodann in der üblichen Weise auf.
Man kann das Aminodibenzanthron wäh rend der Reaktion, aus der entsprechenden Nitroverbindung und einem Reduktionsmittel, zum Beispiel Hydrazinhydrat oder Schwefel, erzeugen.
Statt des 1 .5-Dichloranthrachinons kann man auch 30 Teile 1.5-Dinitroarithrachinon verwenden. In diesem Falle muss von dem fertigen Aminodibenzanthron ausgegangen werden, oder die Reduktion des Nitrodiben- zanthrons zu Aminodibenzanthron schon vor Zugabe des 1. 5-Dinitroanthrachinons zu Ende geführt sein.
Process for the preparation of a valuable vat dye. The main patent describes a process for the preparation of a valuable vat dye in which aminodibenzanthrone, which can be obtained by reducing the mononitrodibenzanthrone produced by nitrating dibenzanthrone, is condensed with an anthraquinone negatively substituted in the 1-position.
It has now been found that a similar valuable vat dye is obtained if aminodibenzanthrone, which can be obtained by reducing the mononitrodibenzanthrone formed by nitriding of dibenzanthrone, is condensed with an anthraquinone negatively substituted in the 1-5 position. The condensation is conveniently carried out in high-boiling solvents or diluents, and acid-binding agents can also be added.
In many cases, the use of catalysts is advantageous, as which, for example, mixtures of sodium acetate and copper salts can be used.
The new vat dye is a black powder; it is soluble in concentrated sulfuric acid with a violet color and dyes cotton from a blue vat in gray to black, exceptionally real shades. Example: 94 parts of aminodibenzanthrone are suspended in 1000 parts of nitrobenzene, 30 parts of sodium acetate, 7 parts of copper oxide and 28 parts of 1,5-dichloroanthraquinone are added, and the mixture is boiled with stirring until the resulting reaction product is practically halogen-free. You then work up in the usual way.
The aminodibenzanthrone can be generated during the reaction from the corresponding nitro compound and a reducing agent, for example hydrazine hydrate or sulfur.
Instead of the 1.5-dichloroanthraquinone, you can also use 30 parts of 1.5-dinitroarithraquinone. In this case, the finished aminodibenzanthrone must be used as the starting point, or the reduction of the nitrodibenzanthrone to aminodibenzanthrone must be completed before the 1,5-dinitroanthraquinone is added.
