Description
Zusatzpatent zum Hauptpatent Nr. 284075. Verfahren zur Herstellung eines chromhaltigen Äzofarbstoffes. Es wurde gefunden, dass man zu einem neuen wertvollen, chromhaltigen Azofarb- stoff gelangt, wenn man auf ein Gemisch der
EMI0001.0005
entsprechen, chromabgebende Mittel derart einwirken lässt, dass ein chromhaltiger Azo- farbstoff entsteht, der je ein Molekül der zwei Ausgangsmonoazofarbstoffe an ein Chromatom komplex gebunden enthält..
Der neue chromhaltige Farbstoff bildet ein graublaues Pulver, das sich in Wasser mit blauer und in konzentrierter Schwefelsäure mit roter Farbe löst und Wolle aus neutralem oder schwach essigsaurem Bade in grünstichig grauen Tönen färbt.
Die zwei beim vorliegenden Verfahren als Ausgangsstoffe dienenden Monoazofarbstoffe können nach an sich bekannten Methoden her gestellt werden, indem man diazotiertes 4- Acetylamino-6-nitro-2-amino-l-oxybenzol mit 1-Acetylamino-7-oxynaphthalin und diazotier- tes 2-Amino-l-oxybenzol-4-sulfonsäureamid mit 1-Acetylamino-7-oxynaphthalin jeweils in alka lischem Medium kuppelt.
über die zu verwendenden chromabgeben den Mittel und Reaktionsbedingungen, gibt das Hauptpatent Auskunft. zwei Monoazofarbstoffe, die den folgenden Formeln <I>Beispiel:</I> 18,8 Teile 2-Amino-l-oxybenzol-4-sulfon- säureamid werden in 200 Teilen Wasser und 15 Volumteilen 10-n-Salzsäure aufgeschlämmt und bei 5 bis 10 mit 25 Volumteilen 4-n- Natriumnitritlösung diazotiert. Die durch Zu gabe von Natriumcarbonat neutralisierte Di- <RTI
ID="0001.0032"> azoverbindung lässt man einlaufen in eine mit Eis auf 0 abgekühlte Lösung von 20,5 Teilen 1-Acetylamino-7-oxynaphthalin in 52 Volumteilen 2-n-Natriumhydroxydlösung und 50 Volumteilen 2-n-Natriumearbonatlösung. Nach beendeter Kupplung wird der abgeschie dene Farbstoff filtriert und mit verdünnter Natriumchloridlösung gewaschen und getrock net.
40 Teile des so erhaltenen Farbstoffes und 42,3 Teile des aus 4-Acetylamino-6-nitro- 2-amino-l-oxybenzol und 1-Acetylamino-7-oxy- naphthalin nach ähnlicher Methode erhaltenen Farbstoffes werden in 3000 Teilen Wasser aufgeschlämmt und mit 220 Teilen einer Lö sung von chromsalieylsaurem Natrium mit einem Chromgehalt von 2,
6 % versetzt. Nach 6 Stunden Kochen am Rückflusskühler ist die Chromierung beendet. Die erhaltene Chrom verbindung wird durch Natriumehloridzugabe abgeschieden und abfiltriert.

Additional patent to main patent No. 284075. Process for the production of a chromium-containing azo dye. It has been found that a new valuable, chromium-containing azo dye is obtained if one uses a mixture of
EMI0001.0005
corresponding, lets chromium-releasing agents act in such a way that a chromium-containing azo dye is created, which contains one molecule of each of the two starting monoazo dyes complexed to a chromium atom ..
The new chromium-containing dye forms a gray-blue powder that dissolves in water with blue and in concentrated sulfuric acid with red color and dyes wool from neutral or weakly acetic acid baths in greenish gray tones.
The two monoazo dyes used as starting materials in the present process can be prepared by methods known per se by diazotized 4-acetylamino-6-nitro-2-amino-1-oxybenzene with 1-acetylamino-7-oxynaphthalene and diazotized 2 -Amino-1-oxybenzene-4-sulfonic acid amide coupled with 1-acetylamino-7-oxynaphthalene in an alkaline medium.
The main patent provides information on the chromium-releasing agents to be used and the reaction conditions. two monoazo dyes which have the following formulas <I> Example: </I> 18.8 parts of 2-amino-1-oxybenzene-4-sulfonic acid amide are slurried in 200 parts of water and 15 parts by volume of 10N hydrochloric acid and at 5 up to 10 diazotized with 25 parts by volume of 4N sodium nitrite solution. The Di- <RTI neutralized by adding sodium carbonate
ID = "0001.0032"> azo compound is allowed to run into a solution, cooled to 0 with ice, of 20.5 parts of 1-acetylamino-7-oxynaphthalene in 52 parts by volume of 2-n sodium hydroxide solution and 50 parts by volume of 2-n sodium carbonate solution. After the coupling has ended, the dyestuff deposited is filtered off and washed with dilute sodium chloride solution and dried.
40 parts of the dye thus obtained and 42.3 parts of the dye obtained from 4-acetylamino-6-nitro-2-amino-1-oxybenzene and 1-acetylamino-7-oxynaphthalene by a similar method are suspended in 3000 parts of water with 220 parts of a solution of sodium chromium saline with a chromium content of 2,
6% offset. After 6 hours of boiling on the reflux condenser, the chromation is complete. The chromium compound obtained is deposited by adding sodium chloride and filtered off.

correspond, lets chromium-releasing agents act in such a way that a chromium-containing azo dye is formed which contains one molecule of each of the two starting monoazo dyes complexed to a chromium atom.
The new chromium-containing dye forms a gray-blue powder that dissolves in water with blue and in concentrated sulfuric acid with red color and dyes wool from neutral or weakly acetic acid baths in greenish gray tones.
