Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 136650.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen  neuen Farbstoff erhält, wenn man 1     Mol     des     5,5'-Diogy-7,7'-disulfo-1,2,2',1'-dinaphtha-          zins    mit 2     Mol        diazotierter        4-Chlor-2-amino-l-          phenol-6-sulfosäure    kombiniert und den er  haltenen Farbstoff mit kupferabgebenden  Mitteln behandelt.  



  Der neue kupferhaltige     Farbstoff    ist  trocken ein dunkles Pulver, welches in Was  ser und in verdünnten Alkalien mit blauer  und in konzentrierter Schwefelsäure mit grün  schwarzer Farbe löslich ist. Baumwolle wird  aus     sodaalkalischem    Bade in echten, insbe  sondere lichtechten, blaugrauen Tönen an  gefärbt.  



  <I>Beispiel:</I>  47,2 Teile des     5,5'-Dioxy-7,7'-disrrlfo-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-aminophenol-6-sulfo-          säure    kombiniert. Dieser Farbstoff wird in  3000 Teilen Wasser gelöst und bei Koch-         temperatur    mit 50 Teilen kristallisiertem  Kupfersulfat versetzt, worauf sich die Kupfer  verbindung des     Farbstoffes    bildet welche  mit Kochsalz aus der Lösung abgeschieden  wird.



  <B> Additional patent </B> to main patent No. 136650. 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'-diogy-7,7'-disulfo-1,2,2 ', 1'-dinaphthazine is mixed with 2 moles of diazotized 4-chlorine Combined -2-amino-l-phenol-6-sulfonic acid and treated the dye obtained with copper donors.



  The new copper-containing dye is a dry, dark powder, which is soluble in water and in dilute alkalis with blue and in concentrated sulfuric acid with green-black color. Cotton is dyed from a soda-alkaline bath in real, especially lightfast, blue-gray tones.



  <I> Example: </I> 47.2 parts of the 5,5'-dioxy-7,7'-disrrlfo-1,2, 2 ', 1'-dinaphthazins 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-aminophenol-6-sulfonic acid. This dye is dissolved in 3000 parts of water and 50 parts of crystallized copper sulfate are added at the boiling temperature, whereupon the copper compound of the dye is formed, which is separated from the solution with common salt.
