Description
Verfahren zur Herstellung eines ehr omierbar en Nonoazofarbstoifes. Gegenstand des vorliegenden Zusatz patentes ist ein Verfahren zur Herstellung eines chromierbaren Monoazofarbstoffes, da durch gekennzeichnet, dass 4-Äthyl-l-oxy- naphthalin in alkalischer Lösung mit der Diazoverbindung aus 1- Amino - 2 - oxynaph- thalin-4-sulfonsäure vereinigt wird.
Der neue Farbstoff bildet ein dunkles Pulver und färbt Wolle nach dem Nach- chromierungsverfahren in rotstichig dunkel blauen, echten Tönen.
<I>Beispiel:</I> 17,2 Teile 4-Äthyl-l-oxynaphthalin wer den mit 200 Teilen 30 % iger Natronlauge an- geteigt und hierauf mit 25 Teilen der Diazo- verbindung der 1-Amino-2-oxynaphthalin-4- sulfonsäure, die man allmählich zufügt, ver rührt; dann lässt man die dunkelblaue Farb- stoffpaste über Nacht stehen, verdünnt mit Wasser, salzt mit Kochsalz aus und nutscht den Farbstoff ab.
Zwecks weiterer Reini gung wird der Farbstoff nochmals in Wasser aufgenommen, mit Kochsalz ausgefüllt, ab genutscht und getrocknet. Man erhält ein dunkles Pulver, das sich in Wasser löst und Wolle nach dem Nachchromierungsverfahren in rotstichig dunkelblauen Tönen färbt.
Process for the production of an honorable nonoazo dye. The subject of the present additional patent is a process for the production of a chromable monoazo dye, characterized in that 4-ethyl-1-oxynaphthalene is combined in alkaline solution with the diazo compound of 1- amino-2-oxynaphthalene-4-sulfonic acid .
The new dye forms a dark powder and uses the post-chroming process to dye wool in real shades of reddish, dark blue.
<I> Example: </I> 17.2 parts of 4-ethyl-1-oxynaphthalene are made into a paste with 200 parts of 30% sodium hydroxide solution and then with 25 parts of the diazo compound of the 1-amino-2-oxynaphthalene 4- sulfonic acid, which is gradually added, stirred ver; then the dark blue dye paste is left to stand overnight, diluted with water, salted out with common salt and the dye is suction filtered.
For the purpose of further cleaning, the dye is taken up again in water, filled with table salt, suction filtered and dried. A dark powder is obtained which dissolves in water and dyes wool in reddish-tinged dark blue shades by the post-chrome plating process.
