Description

  

  Verfahren zur Darstellung der Kupferverbindung eines     substantiven        Azofarbstoffes.       Es     wurde    gefunden, dass der     substantive          Azofarbstoff,    wie er aus zwei Molekülen der       Diazoverbindung    aus     4-Chlor-2-aminophenol-          glyzerinäther    und einem Molekül 5 .     5'-Diogy-          2.2'-dinaphtylharnstoff-7.7'-disulfosäure    er  halten werden kann, in eine Kupferverbin  dung übergeführt wird, wenn man auf den  selben ein kupferabgebendes     Mittel    ein  wirken lässt.

   Der erhaltene kupferhaltige       Azofarbstoff    zieht auf die pflanzliche Faser  in licht-,     alkali-    und bügelechten rötlich  violetten Tönen von     bemerkenswerter    Klar  heit.  



  <I>Beispiel:</I>  <B>1006</B> Gewichtsteile des     Azofarbstoffes    aus  2 Molekülen     4-Chlor-2-aminophenolglyzerin-          äther    und 1 Molekül     5.5'-Diozy-2.2'-di-          naphtylharnstoff-7.7'-disulfosäure    werden in  26,000     Volumteilen    Wasser gelöst, mit Essig  säure deutlich sauer gemacht und bei 80   mit  250 Gewichtsteilen kristallisiertem Kupfer  sulfat versetzt. Unter Rühren     wird    zwei  Stunden auf 80   erwärmt, die Ausscheidung  der     Farbstoffsäure    eventuell durch Kochsalz    vervollständigt,     abgepresst    und getrocknet.

    Der Farbstoff zieht aus dem     Glaubersalz-          Sodabad    in licht-,     alkali-    und bügelechten       rötlichvioletten    Tönen von bemerkenswerter  Klarheit.



  Process for the preparation of the copper compound of a substantive azo dye. It was found that the substantive azo dye, as it is composed of two molecules of the diazo compound from 4-chloro-2-aminophenol glycerol ether and one molecule of 5. 5'-Diogy-2.2'-dinaphtylurea-7.7'-disulphonic acid can be obtained, is converted into a copper compound if a copper-releasing agent is allowed to act on the same.

   The copper-containing azo dye obtained draws onto the vegetable fiber in light-, alkali- and iron-fast reddish purple tones of remarkable clarity.



  <I> Example: </I> <B> 1006 </B> parts by weight of the azo dye from 2 molecules of 4-chloro-2-aminophenol glycerol ether and 1 molecule of 5.5'-diocy-2.2'-di-naphthylurea-7.7'- Disulfonic acid are dissolved in 26,000 parts by volume of water, made significantly acidic with acetic acid and 250 parts by weight of crystallized copper sulfate are added at 80. The mixture is heated to 80 for two hours with stirring, the precipitation of the dye acid is possibly completed with sodium chloride, pressed off and dried.

    The dye draws from the Glauber's salt soda bath in light-, alkali- and iron-fast reddish-purple tones of remarkable clarity.
