Description

  

  Verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es wurde gefunden,     dass    man einen neuen  metallhaltigen Farbstoff erhält, wenn man  den Farbstoff aus der nitrierten     1-Diazo-2-          oxyiiaphthalin-4-sulfosäure    und     P-Naphthol     zusammen mit dem durch Reduktion der     Nitro-          gruppe    des     gleiühen    Farbstoffes erhaltenen       Aminoazofarbstoff    mit chromabgebenden Mit  teln behandelt.  



  Das neue Produkt stellt ein schwärzliches  Pulver dar, löst sich in Wasser mit blauer,       in        10%iger        Natronlauge        mit        violetter,        in     konzentrierter Schwefelsäure mit     schwärzlich-          blauer    Farbe und färbt Wolle und Seide in       schwärzlichblauen    Tönen von vorzüglichen  Echtheitseigenschaften.

      <I>Beispiel:</I>  Eine kurz aufgekochte Suspension von 45  Teilen des Farbstoffes aus der nitrierten     Diazo-          verbindung    der     1-Amino-2-oxynaphtbalin-4-          sulfosäure    und     fl-Naphthol    und 42 Teilen  des durch Reduktion der Nitrogruppe des  gleichen Farbstoffes erhaltenen Aminoazofarb-         stoffes    in<B>600</B> Teilen Wasser werden mit<B>50</B>  Teilen kristallisiertem     Natriumacetat    und     65          Teilen        einer        41        %        Cr20,

  s        enthaltenden        Chrom-          formiatlösung    versetzt und längere Zeit unter       Rückfluss    gekocht. Alsdann werden<B>300</B>     Volum-          teile    gesättigter     Kochsalzlösung    zugesetzt und  <B>15</B> Stunden weitergekocht, nach welcher Zeit  die     Chromierung    beendet ist. Durch     Aus-          -salzen    der siedenden Lösung kann die neue  einheitliche Chromverbindung abgeschieden  werden.



  Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye is obtained if the dye is obtained from the nitrated 1-diazo-2-oxyiiaphthalene-4-sulfonic acid and P-naphthol together with the aminoazo dye obtained by reducing the nitro group of the same dye with chromium donating Treated with means.



  The new product is a blackish powder, dissolves in water with blue, in 10% caustic soda with violet, in concentrated sulfuric acid with blackish-blue color and dyes wool and silk in blackish-blue tones with excellent fastness properties.

      <I> Example: </I> A briefly boiled suspension of 45 parts of the dye from the nitrated diazo compound of 1-amino-2-oxynaphthalene-4-sulfonic acid and fl-naphthol and 42 parts of the same by reducing the nitro group The aminoazo dye obtained in <B> 600 </B> parts of water is mixed with <B> 50 </B> parts of crystallized sodium acetate and 65 parts of a 41% Cr20,

  s containing chromium formate solution and refluxed for a long time. Then <B> 300 </B> parts by volume of saturated sodium chloride solution are added and the mixture is boiled for a further 15 hours, after which the chromation is complete. The new, uniform chromium compound can be separated out by salting out the boiling solution.
