Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Pentakis- azofarbstoffes. Das Verfahren besteht darin,
das man 1 Mol tetrazotierten Benzidins mit 1 Mol eines in saurem Medium aus 1-Amino- 5-naphthol-7-sulfonsäur9 und diazotierter p- Sulfanilsäure gebildeten Monoazofarbstoffes und 1 Mol Resoroin in. sodalkalischem Me dium vereinigt und auf <RTI

Wenn die Bildung des Monoazo- farbstoffes beendet ist, lässt man eine Lösung von 184 kg tetrazotiertem Bernzidin zulaufen und stellt die Reahtionvmisehung sodaalka- li8ch. Ist die Bildung diez-er Stufe beendet, so fügt man eine Lösung von<B>110</B> kg Resor- cin hinzu und führt die Kupplung sodaalka- lisch durch.
Nun lässt man in das Kupp lungsgemisch eine Lösung von 21$ kg diazo- tierter 4-Nitranil.in-2-sulfonsäure zufliessen, welche nach kurzer Kupplungsdauer ver schwunden ist. Nachdem noch eine Lösung von 375 kg Soda in etwa 1400 Liter Wasser zugefügt worden ist, wird zum Schluss eine solche von 13,8 kg diazotiertem p-Nitra- nilin zugegeben.

Am nächsten Morgen wird der F'arb- Stoff mit 5 % Kochsalz bei gleichzeitigem Abstumpfen bis zur schwach alkalischen Reaktion aus,gesalzen, gepresst und getrock net.
Perfabren for the production of a pentakisazo dye. The main patent and its addition No. 195532 relate to processes for the production of polyazo dyes. The dyes are obtained by using the diazoazo compound formed in an acidic medium from 1 hol tetrazotized benzidine and 1,142o1 1,8-amino # naphthol-3;
6 - disulfonic acid or 1 mole of 2i-amino-5-naphthol-7-sulfonic acid alkaline with 1 mole of p - sulfanilic acid and subsequently with resorcinol and coupled to the trisazofan material thus obtained, 2 moles of diazotized p-nitroaniline or each 1 mol of diazotized p-nitroaniline and d2.azotized 4-nitroaniline- <RTI
ID = "0001.0032"> lets 2-sulfonic acid act. The dyes thus obtainable are particularly suitable for dyeing leather.
It has now been found that dyes from. same .good properties it holds when you 1 mole of one. 4,4'-Tetrazodiphenyls with one formed in an acid medium:
Azo dye composed of a component capable of coupling in an acidic and alkaline medium and a monodiazo compound and resorcinol or its derivatives combined in any order, and 1 mol of a mono diazo compound or 2 pods of the same or different monodiazo compounds simultaneously or one after the other on the azo dye thus obtained Act
leaves.
The subject of the present patent is a process for the production of a pentakis azo dye. The procedure consists in
1 mole of tetrazotized benzidine is combined with 1 mole of a monoazo dye formed in an acidic medium from 1-amino-5-naphthol-7-sulfonic acid and diazotized p-sulfanilic acid and 1 mole of resoroin in soda-alkaline medium and to <RTI
ID = "0001.0088"> den; Trisazo dye obtainable in this way allows 1 mol of diazotized 4-nitranfin-'2i-sulfonic acid and diazotized p-nitroaniline to act. The dye dissolves in water with brown, in concentrated sulfuric acid with a deep blue-black color.
<I> Example: </I> 2.85 kg of 2-amino-5-naphthol-7-sulfonic acid sodium are combined in an acidic medium with: .109 lig of diazotized p-sulfanilic acid (? Aqu).
When the formation of the monoazo dye is complete, a solution of 184 kg of tetrazotized amberzidine is allowed to run in and the reaction mixture is made soda-alkali. When the formation of this stage has ended, a solution of <B> 110 </B> kg of resorcinol is added and the coupling is carried out using soda-alkali.
A solution of 21 kg of diazotized 4-nitroanilyn-2-sulfonic acid is now allowed to flow into the coupling mixture, which has disappeared after a short coupling time. After a solution of 375 kg of soda in about 1400 liters of water has been added, a solution of 13.8 kg of diazotized p-nitriline is added at the end. This clutch runs overnight.
The next morning, the dye is removed, salted, pressed and dried with 5% table salt while at the same time dulling it to a weakly alkaline reaction.
