Description

  

      Zusatzpatent    zum Hauptpatent Nr. 143026.    Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffes.    Es wurde gefunden; dass man einen neuen  metallhaltigen Farbstoff erhält, wenn man  den     Azofarbstoff    aus     5-Nitro-2-diazo-l-pbenol     und     1-Amino-8-oxynaphthalin-4-srilfosäure    mit       chrom-    und kupferabgebenden Mitteln be  handelt.  



  Der erhaltene metallhaltige     Farbstoff    bil  det getrocknet ein dunkles Pulver, das sich  in Wasser mit blaugrüner Farbe löst und  Naturseide in blaugrünen Tönen färbt.  



  <I>Beispiel:</I>  8,08 Teile des Farbstoffes aus     diazotier-          tem        5-Nitro-2-amino-l-plienol    und     1-Amino-          8-oxynaphthalin-4-sulfosäure    werden in 500  Teilen Wasser gelöst und mit einer 1,06 Tei  len     Crz    Os entsprechenden Menge     Fluorchrom     am     Rückfluss    gekocht. Nach 24 Stunden  werden 3,25 Teile kristallisiertes Kupfersul  fat zugegeben, die frei werdende Mineralsäure    mit 1,77 Teilen     Natriumacetat    abgestumpft  und noch kurze Zeit weitergekocht.

   Hierauf  wird die gebildete     Chrom-Kupferverbindung     des Farbstoffes mit Kochsalz abgeschieden,  filtriert und bei     mässigerTemperaturgetrocknet.  



      Additional patent to main patent no. 143026. Process for the production of a new metal-containing dye. It was found; that you get a new metal-containing dye if you treat the azo dye from 5-nitro-2-diazo-1-pbenol and 1-amino-8-oxynaphthalene-4-srilfosäure with chromium and copper donating agents be.



  When dried, the metal-containing dye obtained forms a dark powder which dissolves in water with a blue-green color and dyes natural silk in blue-green tones.



  <I> Example: </I> 8.08 parts of the dye from diazotized 5-nitro-2-amino-1-plienol and 1-amino-8-oxynaphthalene-4-sulfonic acid are dissolved in 500 parts of water and mixed with an amount of fluorochrome corresponding to 1.06 parts of Crz Os is refluxed. After 24 hours, 3.25 parts of crystallized copper sulfate are added, the mineral acid released is blunted with 1.77 parts of sodium acetate and the mixture is boiled for a short time.

   The chromium-copper compound formed in the dye is then deposited with common salt, filtered and dried at a moderate temperature.
