PATENTAMT.PATENT OFFICE.
In der Patentschrift 157685 sind blaugraue bis rotgraue Farbstoffe der Anthracenreihe beschrieben, welche durch Verschmelzen der Diamidoanthrachinone bezw. deren Sulfosäuren mit kaustischen Alkalien entstehen. Es wurde nun gefunden, daß man zu rotbraunen Farbstoffen gelangt, wenn man an Stelle der Diamidoanthrachinone die in der Patentschrift 123745 beschriebenen Formalde-Iodverbindungen der Diamidoanthrachinone ι · 5 und ι · 8 mit kaustischen Alkalien verschmilzt. Diese Farbstoffe besitzen ebenso wie die des Haupt - Patentes — abgesehen von der anderen Nuance — dieselben Eigenschäften wie das Indanthren und gehören daher offenbar derselben Klasse an. Wie die Indanthrene zeigen sie Echtheitseigenschaften, die diejenigen aller anderen bekannten Farbstoffe übertreffen.In the patent specification 157685 blue-gray to red-gray dyes of the anthracene series described, which BEZW by fusing the diamidoanthraquinones. their sulfonic acids with caustic alkalis. It has now been found that red-brown dyes are obtained if one is on Instead of the diamidoanthraquinones, the formaldehyde-iodine compounds described in patent specification 123745 the diamidoanthraquinones ι · 5 and ι · 8 fused with caustic alkalis. These dyes, like those of the main patent - apart from the other shade - have the same properties like indanthrene and therefore obviously belong to the same class. Like the indanthrenes, they show authenticity properties, which surpass those of all other known dyes.

300 kg kaustisches Kali werden geschmolzen300 kg of caustic potash are melted
und 100 kg-1 · 5-Diamidoanthrachinon-Formaldehydverbindung bei 1700 C. langsam eingetragen. Man erhitzt dann noch 1 Stunde auf 1700 C, gießt in Wasser, kocht auf und filtriert.and 100 kg-1 · 5-diamidoanthraquinone-formaldehyde compound at 170 0 C. slowly entered. The mixture is then heated to 170 ° C. for a further hour, poured into water, boiled up and filtered.
Analog verfährt man bei Verwendung der Formaldehydverbindung des I · 8 - Diamidoanthrachinons. Man kann auch von Mischungen der 1 · 5- und 1 · 8-Verbindung ausgehen.A similar procedure is followed when using the formaldehyde compound of I · 8-diamidoanthraquinone. One can also start from mixtures of the 1x5 and 1x8 compounds.
Die Farbstoffe bilden braunrote Pasten, in trockenem Zustand schwarze Pulver, die in den gebräuchlichen Lösungsmitteln so gut wie unlöslich sind. In Schwefelsäure lösen sie sich mit gelbbrauner Farbe auf. Sie bilden mit Reduktionsmitteln in Gegenwart von Alkalien eine braunrote Küpe, welche die vegetabilische Faser direkt anfärbt.The dyes form brown-red pastes, black powders when dry, which in are practically insoluble in common solvents. Dissolve in sulfuric acid they are yellow-brown in color. They form with reducing agents in the presence a brown-red vat of alkalis, which directly stains the vegetable fibers.
