Description
Zusatzpatent zum Hauptpatent Nr. 99522. Verfahren zur Herstellung eines neuen Azofarlostoffes. Es wurde gefunden, dass man einen neuen Azofarbstoff erhält, wenn man das Arylid aus 2,3-Oxynaphthoesäure und 2-ATnitio-1,1'- diphenyläther mit diazotiertem 4-Chlor-2- amino-1,1'-diphenyläther kuppelt. Der neue Farbstoff bildet ein in Wasser unlösliches, dunkelrotes Pulver.
Auf der Faser oder einem geeigneten Substrat hergestellt, erzeugt er reisrote Töne.
Beispiel: 35,4 Teile 2,3-Oxynaphthoesäure werden in 500 Teilen Wasser unter Zusatz von 4 Teilen Ätznatron gelöst. Hierauf fügt man noch 20 Teile Soda hinzu und versetzt mit einer aus 21,9 Teilen 4-Chlor-2-amino-1,1'- diphenyläther bereiteten Diazolösung. Der gebildete Farbstoff scheidet sich sofort als roter Niederschlag aus.
Additional patent to main patent no. 99522. Process for the production of a new azo-fur. It has been found that a new azo dye is obtained when the arylide of 2,3-oxynaphthoic acid and 2-ATnitio-1,1'-diphenyl ether is coupled with diazotized 4-chloro-2-amino-1,1'-diphenyl ether. The new dye forms a water-insoluble, dark red powder.
Made on fiber or a suitable substrate, it creates rice red tones.
Example: 35.4 parts of 2,3-oxynaphthoic acid are dissolved in 500 parts of water with the addition of 4 parts of caustic soda. 20 parts of soda are then added and a diazo solution prepared from 21.9 parts of 4-chloro-2-amino-1,1'-diphenyl ether is added. The dye formed separates out immediately as a red precipitate.
