Description
<B>Verfahren zur Herstellung</B> eines metallisierbaren Monoazofarbstoffes Gegenstand vorliegenden Patentes ist ein Verfahren zur Herstellung eines metallisier baren Monoazofarbstoffes. Das Verfahren ist dadurch gekennzeichnet, dass man dianotiertes 6-Aeetylamino-4-nitro - 2 - amino -1- oxy - Benzol mit 2-Carbäthoxyam.ino-6-oxy-naphthalin-8- sulfonsäure kuppelt.
Der erhaltene neue Monoazofarbstoff stellt in Form seines Natriumsalzes ein schwarzes Pulver dar, das Wolle aus saurem Bad in rot violetten Tönen färbt, die durch Nachchro- mieren sehr echte grüne Färbungen geben, welehe insbesondere hervorragend lichtecht sind.
<I>Beispiel</I> 21,7 Teile 6-Aeetylamino-4-nitro-2-amino-l- oxy-benzol werden in 200 Teilen Wasser mit 20 Teilen konzentrierter Salzsäure verrührt und dureh Zutropfen einer Lösung von 6,9 Teilen Natriumnitrit in 20 Teilen Wasser bei >-7 dianotiert. Man neutralisiert dann die Diazosuspension bis zum Verschwinden der mineralsauren Reaktion durch Zugabe von.
Natriumbiearbonat und vermischt sie bei 0-5 mit einer kalten Lösung, die man durch Auflösung von 31,1 Teilen 2-Carbäthoxy- amino-6-oxy-naphthalin-8-sulfonsäure mit 6 Teilen Natriumcarbonat in 150 Teilen Was ser unter Zusatz von weiteren 8 Teilen Na- triumcarbonat, 15 Teilen Ammoniakwasser 25o/oig und 10 Teilen Pyridin zur erkalteten Lösung hergestellt hat.
Der gebildete Farb stoff fällt sofort. als schwarzes Pulver aus, und nach einer Stunde ist die Diazoverbin- dung verschwunden. Man rührt noch 16 Stun den bei Zimmertemperatur und filtriert den Farbstoff ab und trocknet ihn. Er wird in Form des Natriumsalzes als schwarzes Pulver erhalten, das sich in Wasser mit blauer Farbe, bei Zusatz verdünnter Säuren mit blauroter und in konzentrierter Schwefelsäure mit roter Farbe löst. Wolle wird aus saurem Bad in rotvioletten Tönen gefärbt, die durch Nach- ehromier en in sehr echte, insbesondere her vorragend lichtechte grüne Töne übergehen.
<B> Process for the production of a metallizable monoazo dye. The present patent relates to a process for the production of a metallizable monoazo dye. The process is characterized in that dianotated 6-acetylamino-4-nitro-2-amino-1-oxy-benzene is coupled with 2-carbethoxyamino-6-oxy-naphthalene-8-sulfonic acid.
The new monoazo dye obtained is, in the form of its sodium salt, a black powder which dyes wool from an acid bath in red-violet shades which, after chromating, give very real green dyes, which are especially excellent lightfast.
<I> Example </I> 21.7 parts of 6-ethylamino-4-nitro-2-amino-l-oxy-benzene are stirred in 200 parts of water with 20 parts of concentrated hydrochloric acid and a solution of 6.9 parts is added dropwise Sodium nitrite in 20 parts of water is dianotized at> -7. The diazo suspension is then neutralized until the mineral acid reaction disappears by adding.
Sodium bicarbonate and mixed it at 0-5 with a cold solution, which can be obtained by dissolving 31.1 parts of 2-carbethoxy-amino-6-oxy-naphthalene-8-sulfonic acid with 6 parts of sodium carbonate in 150 parts of water with the addition of more 8 parts of sodium carbonate, 15 parts of 25% ammonia water and 10 parts of pyridine to the cooled solution.
The dye formed falls immediately. as a black powder, and after an hour the diazo compound has disappeared. The mixture is stirred for a further 16 hours at room temperature and the dye is filtered off and dried. It is obtained in the form of the sodium salt as a black powder which dissolves in water with a blue color, with the addition of dilute acids with a blue-red color and in concentrated sulfuric acid with a red color. From an acid bath, wool is dyed in red-violet tones, which are transformed into very real, in particular extremely light-fast, green tones through post-processing.
