Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 189140. \'erfahren zur Darstellung eines neuen Monoazofarbstoffes. Es wurde gefunden, dass man einen neuen, wertvollen Monoazofarbstoff erhält, wenn man die Diazoverbindung von 1-Amino-2-(2'-me- thyl)-phenoxybenzol von der Formel
EMI0001.0006
mit 2-(4'-Methylphenyl)-sulfonylamino-5-oxy- naphthalin-1,7-disulfonsäure kuppelt.
Der neue Farbstoff, ein gelbrotes Pulver, löst sich in Wasser gelbrot, in konzentrierter Schwefelsäure rotviolett und färbt Wolle und Seide in echten, gelbroten Tönen.
<I>Beispiel:</I> 39,8 Teile 1-Amino-2-(2'-rnethyl)-phenoxy- benzol werden dianotiert und mit 95,6 Teilen 2-(4'-Methylphenyl)-sulfonylamino-5-oxynaph- thalin-1,7-distalfonsäur-e unter gutem Rühren bei 0 C in verdünnter Lösung in Gegenwart von überschüssigem Natriumazetat gekuppelt. Nach Beendigung der Farbstoffbildung wird der mit wenig Salz vollständig ausgeschie dene Farbstoff filtriert und getrocknet. Der erhaltene Farbstoff bildet ein gelb rotes Pulver, das sich in Wasser mit gelb roter, in konzentrierter Schwefelsäure mit rotvioletter Farbe löst und Wolle und Seide in echten gelbroten Tönen anfärbt.
<B> Additional patent </B> to main patent no. 189140. \ 'Learned about the presentation of a new monoazo dye. It has been found that a new, valuable monoazo dye is obtained if the diazo compound of 1-amino-2- (2'-methyl) -phenoxybenzene has the formula
EMI0001.0006
with 2- (4'-methylphenyl) -sulfonylamino-5-oxynaphthalene-1,7-disulfonic acid.
The new dye, a yellow-red powder, dissolves yellow-red in water and red-violet in concentrated sulfuric acid and dyes wool and silk in real, yellow-red tones.
<I> Example: </I> 39.8 parts of 1-amino-2- (2'-methyl) -phenoxy-benzene are dianotized and mixed with 95.6 parts of 2- (4'-methylphenyl) -sulfonylamino-5- oxynaphthalin-1,7-distalfonsäur-e coupled with thorough stirring at 0 C in dilute solution in the presence of excess sodium acetate. After the formation of the dye has ended, the dye, which has been completely eliminated with a little salt, is filtered off and dried. The dye obtained forms a yellow-red powder that dissolves in water with yellow-red, in concentrated sulfuric acid with red-violet color and dyes wool and silk in real yellow-red tones.
