Description
Verfahren zur Herstellung eines metallhaltigen Azofarhstoffes. Gegenstand. des vorliegenden Patentes ist ein Verfahren zier Herstellung eines metall haltigen Azofarbstoffes, welches darin besteht, dass man 1 Mol diazotiertes 1-Oxy-2-amino-4- nitrobenzol mit 1 Mol 1-Oxy-2-acetylamino-4- methylbenzol kuppelt und die erhaltene Mono- azoverbindung mit einem chromabgebenden Mittel behandelt.
Im nachfolgenden Beispiel bedeuten die Teile Gewichtsteile.
Beispiel: 19,8 Teile der durch Kuppeln von diazo- tiertem 1-0xy-2-amino-4-nitrobenzol mit 1-Oxy- 2 - aeetylamino - 4 - methylbenzol erhältlichen .#Ionoazoverbindung werden in 400 Teilen Wasser von 25 angesehlämmt. Man setzt der Suspension 7,15 Teile kristallisiertes Natrium biehromat zu,
stellt ihren pn-Wert auf 6 und kocht sie 4-5 Stunden lang unter Rühren am Ftüekfluss. Man fällt die gelöste Ch.romkom- plexverbindung bei 85 durch Zugabe von Natriuulchlorid aus der Lösung aus, filtriert sie ab, wäscht den Filterkuchen mit 5o/oiger Natriumehloridlösung und trocknet ihn im Vakuum bei 90 .
Der neue chromhaltige Azofarbstoff ist ein dunkles Pulver, welches sich in Wasser mit rotbrauner, in konzentrierter Schwefel säure mit oranger Farbe löst und Wolle, Seide und synthetische Polyamidfasern aus neutralem Bad in walk-, wasch- und licht echten braunen Tönen färbt.
Process for the production of a metal-containing azo carbon. Object. of the present patent is a process for the preparation of a metal-containing azo dye which consists in coupling 1 mole of diazotized 1-oxy-2-amino-4-nitrobenzene with 1 mole of 1-oxy-2-acetylamino-4-methylbenzene and the obtained monoazo compound treated with a chromium donating agent.
In the following example, the parts are parts by weight.
Example: 19.8 parts of the ionoazo compound obtainable by coupling diazo-2-amino-4-nitrobenzene with 1-oxy-2-aetylamino-4-methylbenzene are slurried in 400 parts of water. 7.15 parts of crystallized sodium biehromat are added to the suspension,
sets its pn value to 6 and cooks it for 4-5 hours while stirring on the river. The dissolved chromium complex is precipitated from the solution at 85 by adding sodium chloride, filtered off, the filter cake is washed with 50% sodium chloride solution and dried in vacuo at 90.
The new chromium-containing azo dye is a dark powder, which dissolves in water with red-brown, in concentrated sulfuric acid with an orange color and dyes wool, silk and synthetic polyamide fibers from a neutral bath in full, washable and light brown tones.
