Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 240993. Verfahren zur Herstellung eines kupferbaren Polyazofarbstoffes. Gegenstand vorliegenden Patentes ist ein Verfahren zur Herstellung eines kupferbaren Polyazofarbstoffes. Das Verfahren ist da durch gekennzeichnet, dass. man tetrazotier- ten 4,4'-Diamino-2,2',5,
5'-tetramethoxy-di- phenylharnAtoff mit 1 Mol des durch saure Kupplung von dianotierter 2-Amino-benzoe- säure mit 2-Amino-5-oxy-naphthalin-7-sul- fonsäure erhaltenen Monoazofarbstoffes, und mit 1 Mol 1-Amino-8-ogy-naphthalin-2,4-di- sulfonsäure kuppelt.
Der neue Trisazofarbstoff stellt ein dunkles, bronzierendes Pulver dar, das sich in Wasser mit blauer, in konzentrierter Schwefelsäure mit grünstichig blauer Farbe löst. Er färbt Baumwolle und Fasern aus re generierter Cellulose in marineblauen Tönen. Nass- und Lichtechtheiten werden durch Nachbehandeln mit Kupfersalzen verbessert.

n., zotiert und in Gegenwart von Bicarbonat halbseitig mit<B>38,7</B> Teilen des Monoazofarb- stoffes, erhalten durch saure Kupplung von dianotierter 2-Aminobenzoesäure mit 2-Amino- 5-oxy-naphthalin-7-sulfonsäure, gekuppelt.
Zur Zwischenverbindung lässt man alsdann eine wässrige Lösung von<B>31,9</B> Teilen 1-Amino -8- oxy-naphthalin-2,4-disulf onsäure, 20 Teilen Soda und<B>150</B> Teilen Pyridin fliessen. Nachdem die Kupplung durch mehr stündiges Rühren bei Raumtemperatur be endet worden ist, wird der Farbstoff bei 40 mit Kochsalz gefällt, abfiltriert und ge trocknet.
<B> Additional patent </B> to main patent no. 240993. Process for the production of a copper-compatible polyazo dye. The present patent relates to a process for the preparation of a copperable polyazo dye. The process is characterized in that. Tetrazotized 4,4'-diamino-2,2 ', 5,
5'-tetramethoxy-diphenylurAtoff with 1 mol of the monoazo dye obtained by acid coupling of dianotated 2-amino-benzoic acid with 2-amino-5-oxy-naphthalene-7-sulfonic acid, and with 1 mol of 1-amino -8-ogy-naphthalene-2,4-disulfonic acid couples.
The new trisazo dye is a dark, bronzing powder that dissolves in water with a blue color, in concentrated sulfuric acid with a greenish blue color. It dyes cotton and fibers made from regenerated cellulose in navy blue tones. Wet and light fastness properties are improved by post-treatment with copper salts.
EMI0001.0023
n., zotiert and in the presence of bicarbonate on one side with 38.7 parts of the monoazo dye, obtained by acid coupling of dianotated 2-aminobenzoic acid with 2-amino-5-oxy-naphthalene-7-sulfonic acid , coupled.
An aqueous solution of 31.9 parts of 1-amino-8-oxy-naphthalene-2,4-disulphonic acid, 20 parts of soda and 150 parts is then allowed to form the intermediate compound Pyridine flow. After the coupling has been completed by stirring for more hours at room temperature, the dye is precipitated with sodium chloride at 40, filtered off and dried.
