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'-Dioxy-          2    . 2'-     dinaphtylamin-    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 violetten  Tönen von bemerkenswerter Klarheit.  



  <I>Beispiel</I>  963 Gewichtsteile des     Azofarbstoffes    aus  2 Molekülen     4-Chlor-2-aminophenolglyzerin-          äther    und 1 Molekül     5.5'-Dioxy-2.2'-di-          napthylamin    -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-,     a.lkali-    und bügelechten  violetten Tönen von bemerkenswerter Klar  heit.



  Process for the preparation of the copper compound of a substantive azo dye. It has been found that the substantive azo dye as it is composed of two molecules of the diazo compound from 4-chloro-2-aminophenol. glycerin ether and one molecule 5. 5'-dioxy-2. 2'-dinaphthylamine- 7. 7'-disulfonic acid er.

    can be held, is converted into a copper compound if one lets a copper-releasing agent act on the same. The copper-containing azo dye obtained draws onto the vegetable fiber in light-, alkali- and iron-fast purple tones of remarkable clarity.



  <I> Example </I> 963 parts by weight of the azo dye from 2 molecules of 4-chloro-2-aminophenol glycerol ether and 1 molecule of 5.5'-dioxy-2.2'-di-napthylamine -7. 7'-disulfonic acid are dissolved in 26,000 parts by volume of water, made significantly acidic with acetic acid and mixed with 250 parts by weight of crystallized copper sulfate 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-resistant violet tones of remarkable clarity.
