Verfahren zur Darstellung schwarzer basischer Disazofarbstoffe.
Es wurde gefunden, dass ein wertvoller schwarzer basischer sekundärer Disazofarbstoff erhalten wird, wenn in dem Verfahren des Stammpatentes Nr. 58780 das dort zur Anwendung gebrachte 1. 8-Diaminonaphtalin durch 1. 5-Diaminonphtalin ersetzt wird.
Der auf diese Weise gewonnene Farbstoff färbt Kunstseide im neutralen oder sauren Bade schön schwarz. Es ist das um 80 bemerkenswerter als der analoge Farbstoff der deutschen Patentschrift Nr. 109491 Aminophenyltrimethylammonium # Aminohydrochinon- dimethyläther # 1.5-Aminonaphtol nur blaue Färbungen erreichen lässt.
Die diesem Farbstoff analogen Kombinationen mit anderen primären Basen, zum Beispiel p-Xylidin, Aminokresoläther in Mittelstellung und 1. 5-Diaminonaphtalin in Endstellung färben braun, ähnlich den mit m-Diaminen zusammengesetzten bekannten Kom- binationen.
Es war demnach nicht vorauszusehen, dass dieser Farbstoff ein für die Kunstseide- f, irbung wertvolles Schwarz sein würde, dessen Herstellung einen wesentlichen Fortschritt bedeutet.

säure (190 Be) und etwa 600 l Wasser.
Die Kupplung beginnt in der salzsauren Lösung. Sie wird beschleunigt dur h Abstumpfen der überschüss gen freien Mineralsäure mittels Natriumazetat. Nach kurzem Rühren wird dann auf 40 bis 50 erwärmt und der Farbstoff durch Zusatz von Kochsalzlösung und wenig Chlorzink in kristalliniseher Form abgeschieden. Er ist ein schwarzes Pulver und färbt Chardonnetseide schön tiefschwarz. Die Färbung ist waschecht.

Process for the preparation of black basic disazo dyes.
It has been found that a valuable black basic secondary disazo dye is obtained if in the process of parent patent no. 58780 the 1,8-diaminonaphthalene used there is replaced by 1,5-diaminonaphthalene.
The dye obtained in this way colors artificial silk beautifully black in a neutral or acid bath. It is 80% more remarkable than the analogous dye in German patent specification No. 109491 aminophenyltrimethylammonium # aminohydroquinone dimethyl ether # 1.5-aminonaphtol only produces blue colorations.
The combinations analogous to this dye with other primary bases, for example p-xylidine, aminocresol ether in the middle position and 1,5-diaminonaphthalene in the end position color brown, similar to the known combinations composed of m-diamines.
It was therefore impossible to foresee that this dye would be a valuable black for artificial silk, the production of which would represent a major advance.
EMI1.1
acid (190 Be) and about 600 l of water.
The coupling begins in the hydrochloric acid solution. It is accelerated by blunting the excess free mineral acid with sodium acetate. After brief stirring, the mixture is then heated to 40 to 50 and the dye is precipitated in crystalline form by adding sodium chloride solution and a little zinc chloride. It is a black powder and colors Chardonnese silk beautifully deep black. The color is washable.
