Patentiert im Deutschen Reiche vom 7. November 1907 ab.Patented in the German Empire on November 7, 1907.

In den Patenten 162824 und 174699, Kl. 12 q, ist ein Verfahren zur Darstellung von Dianthrachinonimiden beschrieben, das darin besteht, daß man Halogenanthrachinone auf Aminoanthrachinone in Gegenwart von Metallsalzen, wie z. B. Kupferchlorid, einwirken läßt. Diese sollen dabei 'als Katalysatoren wirken. In der Beschreibung des' Patentes 162824 ist zudem angegeben, daß die Anwendung solcher Metallsalze behufs glatter Durchführung des Prozesses notwendig ist und das Verfahren von den bekannten Kondensationen der Halogenanthrachinone mit Aminen der alphatischen bzw. der Benzol- und Naphtalinreihe unterscheidet.In patents 162824 and 174699, class 12 q, describes a process for the preparation of dianthraquinonimides, which consists in that one haloanthraquinones on aminoanthraquinones in the presence of metal salts, such as B. copper chloride, can act. These are supposed to act as catalysts. In the description of 'patent 162824 is also stated that the use of such metal salts for the purpose of smooth implementation of the Process is necessary and the process of the well-known condensation of haloanthraquinones with amines of the alphatic or the benzene and naphthalene series.

Es wurde nun gefunden, daß a-Nitroanthrachinone mit Aminoanthrachinonen unter Bildung derselben Dianthrachinonimide reagieren, ohne daß Katalysatoren notwendig sind, lediglich in Gegenwart von kohlensauren Alkalien, und daß dieses Verfahren zur technischen Darstellung der α-α- und ci-,6-Dianthrachinonimide geeignet ist. Dies war bei der bekannten Oxydierbarkeit der Aminoanthrachinone nicht zu erwarten.It has now been found that a-nitroanthraquinones with aminoanthraquinones with formation the same dianthraquinonimides only react without the need for catalysts in the presence of carbonate alkalis, and that this process for technical Representation of the α-α- and ci-, 6-dianthraquinone imides suitable is. This was not the case with the known oxidizability of the aminoanthraquinones expected.

Beispiel: 32 Teile α-Nitroanthrachinon und 28 Teile β - Aminoanthrachinon werden in 900 Teilen Nitrobenzolheiß gelöst; die mit 10Teilen Kaliumcarbonat versetzte Lösung wird dann einige Stunden zum Sieden erhitzt und heiß nitriert. Aus dem Filtrat scheidet sich das α - ,8 - Dianthrachinonimid beim Abkühlen auf 70 bis 80° ab; es wird bei dieser Temperatur abfiltriert und mit etwas Alkohol gewaschen. .Example: 32 parts of α-nitroanthraquinone and 28 parts of β-aminoanthraquinone are dissolved in 900 parts of hot nitrobenzene; those with 10 parts Potassium carbonate added solution is then heated to the boil for a few hours and hot nitrided. The α-, 8-dianthraquinonimide separates from the filtrate on cooling 70 to 80 ° from; it is filtered off at this temperature and washed with a little alcohol. .

Der Körper hat die in der Patentschrift 174699 angegebenen Eigenschaften.The body has the properties specified in patent 174699.

An Stelle von ß-Aminoanthrachinon können a-Aminoanthrachinone, an Stelle von a-Nitroanthrachinon α-Dinitroanthrachinone verwendet werden.Instead of ß-aminoanthraquinone, α-aminoanthraquinones can be used instead of α-nitroanthraquinone α-Dinitroanthraquinones can be used.
