Description
Verfahren zur Herstellung eines Monoazofarbstoffes. Gegenstand des vorliegenden Zusatz- patentes ist ein Verfahren zur Herstellung eines Monoazofarbstoffes,dadurch gekenn- zeichnet, -dass man 2-Am.ino-l-phenolocto- decyläther diazotiert und mit 1-O.ynaphth-aa: lin-3,6;disulfon"-äure kuppelt.
Der so erhal tene Farbstoff färbt Wolle und Seide aus saurem und neutralem Bade in echten, roten Tönen.
<I>Beispiel:</I> 36,1 Teile 2-Amino-l-phenoloctodecyl- äther werden in 100 Teilen Äthylalkohol <B>95%</B> und 35 Teilen konz. Salzsäure gelöst und bei<B>10'</B> mit einer konzentrierten wäss- rigen Lösung von 7 Teilen Natriumnitrit di- azotiert. Die Diazoniumverbiudung lässt man zu einer ammoniakalischen Lösung von 30,4 Teilen 1- Ogynaphthalin- 3,
6 -.dsulfonsäure fliessen. Die Kupplung ist in kurzer Zeit be endet. Der Farbstoff wird abfiltriert, gepresst und getrocknet. Er bildet eine .dunkle Masse, die sich in heissem Wasser rot, in konz. Schwefelsäure blau löst.
Process for the preparation of a monoazo dye. The subject of the present additional patent is a process for the production of a monoazo dye, characterized in that 2-amino-1-phenol octodecyl ether is diazotized and 1-O.ynaphth-aa: lin-3,6; disulfonic "acid couples.
The dye obtained in this way dyes wool and silk from acidic and neutral baths in real, red tones.
<I> Example: </I> 36.1 parts of 2-amino-l-phenoloctodecyl ether are concentrated in 100 parts of ethyl alcohol <B> 95% </B> and 35 parts. Dissolved hydrochloric acid and diacotized at <B> 10 '</B> with a concentrated aqueous solution of 7 parts of sodium nitrite. The diazonium compound is allowed to add to an ammoniacal solution of 30.4 parts of 1- ogynaphthalene-3,
6 -.dsulfonic acid flow. The coupling is finished in a short time. The dye is filtered off, pressed and dried. It forms a .dark mass, which turns red in hot water, in conc. Sulfuric acid dissolves blue.
