Description

  

  Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffes.    Es wurde gefunden,     dass'    man einen neuen  wertvollen metallhaltigen Farbstoff erhält,  wenn man den     Azofarbstoff    aus     diazotier-          tem        5-Nitro-2-amino-l-phenol    und     2-Amino-          5-oxynaphthalin-1,7-disulfosäure    mit kupfer  abgebenden Mitteln und mit einem Oxyda  tionsmittel behandelt, wobei diese beiden Ope  rationen nicht gleichzeitig, sondern nachein  ander durchgeführt werden.  



  Der erhaltene metallhaltige Farbstoff  bildet getrocknet ein     schwärzliches    Pulver,  welches in Wasser und in verdünnter Soda  iösung mit violetter und in konzentrierter  Schwefelsäure mit schwärzlicher Farbe lös  lich ist. Er färbt Baumwolle aus     sodaalka-          lischem        Glaubersalzbade    in echten blaugrauen  Tönen an.  



  <I>Beispiel:</I>  Der     Diazakörper    aus 154 Teilen     5-Nitro-          -2-amino-l-phenol    wird in Gegenwart. von  Soda mit 341 Teilen     2-Amino-5-oxynaphtha-          l.in-1.7-disulfosäure        kombiniert    und darauf    der gebildete Farbstoff nach dem Neutrali  sieren mittelst 250 Teilen kristallisiertem  Kupfersulfat in die Kupferverbindung über  geführt. Diese wird in 4000 Teilen Wasser  gelöst und mit 50 Teilen Soda alkalisch ge  stellt, worauf durch Zugabe von     Natrium-          hypochlorit,    mit einem Gehalt von 150 bis  200 Teilen aktivem Chlor, der neue Farb  stoff gebildet wird.

   Zur Beschleunigung der  Reaktion wird leicht     erwärmt.    Durch Ein  dampfen und     Aussalzen    gewinnt man den  neuen Farbstoff.



  Process for the production of a new metal-containing dye. It has been found that a new valuable metal-containing dye is obtained if the azo dye is donated from diazotized 5-nitro-2-amino-1-phenol and 2-amino-5-oxynaphthalene-1,7-disulfonic acid with copper Agents and treated with an oxidizing agent, these two operations not being carried out simultaneously, but one after the other.



  The metal-containing dye obtained forms a blackish powder when dried, which is soluble in water and in dilute soda solution with purple and in concentrated sulfuric acid with a blackish color. He dyes cotton from soda-alkaline Glauber's salt bath in real blue-gray tones.



  <I> Example: </I> The diaza body from 154 parts of 5-nitro- -2-amino-l-phenol is in the presence. of soda combined with 341 parts of 2-amino-5-oxynaphthalene-1,7-disulfonic acid and then, after neutralization, the dye formed is converted into the copper compound using 250 parts of crystallized copper sulfate. This is dissolved in 4000 parts of water and made alkaline with 50 parts of soda, whereupon the new dye is formed by adding sodium hypochlorite with a content of 150 to 200 parts of active chlorine.

   Warm up slightly to accelerate the reaction. The new dye is obtained by steaming and salting out.
