Description
Zusatzpatent zum Hauptpatent Nr. 163539. Verfahren zur Herstellung eines neuen Azofarbstoifes. Es wurde gefunden, dass man einen neuen Azofarbstoff erhält, wenn man dianotiertes 2-Clilor-4-riitranilin mit [ss-(2-Methoxy-5- methyl) - phenylamirio] äthyluiethyläther ver einigt.
Der neue Farbstoff bildet ein dunkles Pulver, das in Wasser unlöslich ist, sich da gegen in Essigester leicht mit blauroter Farbe löst. Er färbt Aoetatseide in blauroten Tönen. <I>Beispiel:</I> 17,25 Teile 2-Chlor-4-nitranilin werden mit Wasser vermahlen und mit 25 Teilen konzentrierter Salzsäure und 7 Teilen Na triumnitrit unter Zusatz von Eis dianotiert. Die erhaltene Diazolösung lässt man zu einer Lösung von 19,5 Teilen [ss-(2-Methoxy-5-nie= thyl) - phenylamirio] äthslmethyläther in ver- dünnten Salzsäure zufliessen.
Dann versetzt man langsam mit Natriumacetatlösung bis die Kupplung beendet ist. Der Farbstoff scheidet sich als dunkles Pulver aus.
Additional patent to main patent no. 163539. Process for the production of a new azo dye. It has been found that a new azo dye is obtained if dianotated 2-chloro-4-riitraniline is combined with [ss- (2-methoxy-5-methyl) phenylamirio] ethyl ethyl ether.
The new dye forms a dark powder that is insoluble in water, whereas it dissolves easily with a bluish red color in ethyl acetate. He dyes acetate silk in blue-red tones. <I> Example: </I> 17.25 parts of 2-chloro-4-nitroaniline are ground with water and dianotized with 25 parts of concentrated hydrochloric acid and 7 parts of sodium nitrite with the addition of ice. The diazo solution obtained is allowed to flow into a solution of 19.5 parts of [ss- (2-methoxy-5-nie = thyl) - phenylamirio] ethyl ether in dilute hydrochloric acid.
Sodium acetate solution is then slowly added until the coupling has ended. The dye separates out as a dark powder.
