Description
Verfahren zur Herstellung eines neuen Azofarbstoffes. Es wurde gefunden, dass man einen neuen Farbstoff erhält, wenn man 1 Mol des 5,5'- Dioxy-7,7'-disulfo-1,2,2',1'-dinaphthazins mit 2 Mol diazotierter 4-Chlor-2-amino-l-phenol- 6-sulfosätire kombiniert.
Der neue Farbstoff ist trocken ein dunk les Pulver, welches in Wasser und in verdünnten Alkalien mit blauer und in kon zentrierter Schwefelsäure reit grünschwarzer Farbe löslich ist. Baumwolle wird aus soda- alkalischem Glaubersalzbade in blauen Tönen angefärbt, die durch Nachbehandlung mit kupferabgebenden Mitteln in echte graublaue Töne umgewandelt werden können.
<I>Beispiel:</I> 47,2 Teile des 5,5'-Dioxy-7,7'-disulfo- 1,2,2',1'-dinaphthazins werden zusammen mit 25 Teilen Soda in 500 Teilen Wasser in Lösung gebracht und mit dem Diazokörper aus 45 Teilen 4-Chlor-2-amiuophenol-6-sulfo- säure kombiniert. Durch Aussalzen wird nach beendetergupplungderFarbatoffabgeschieden.
Process for the production of a new azo dye. It has been found that a new dye is obtained if 1 mole of 5,5'-dioxy-7,7'-disulfo-1,2,2 ', 1'-dinaphthazine is mixed with 2 moles of diazotized 4-chloro-2 -amino-l-phenol- 6-sulfosätire combined.
The new dye is a dry, dark powder, which is soluble in water and in dilute alkalis with blue and in concentrated sulfuric acid a greenish-black color. Cotton is dyed from a soda-alkaline Glauber's salt bath in blue tones, which can be converted into real gray-blue tones by subsequent treatment with copper-releasing agents.
<I> Example: </I> 47.2 parts of the 5,5'-dioxy-7,7'-disulfo-1,2,2 ', 1'-dinaphthazine are mixed with 25 parts of soda in 500 parts of water in Brought solution and combined with the diazo body from 45 parts of 4-chloro-2-amiuophenol-6-sulfonic acid. After coupling is complete, the coloring agent is separated out by salting out.
