Description

  

  Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden,     dass    ein neuer Farb  stoff entsteht, wenn man     1-Amino-4-nitro-          anthrachinon        diazotiert,    hierauf mit     Resorein     kuppelt und das so erhaltene Produkt mit  Reduktionsmitteln behandelt.  



  Der neue Farbstoff bildet ein dunkelvio  lettes Pulver, das sich in konzentrierter  Schwefelsäure mit rotbrauner und in     Toluol          init    rotvioletter Farbe löst. Er färbt die       Acetatseide    in reinen violetten Tönen an.    <I>Beispiel:</I>  <B>13,5</B> Teile     1-Amino-4-nitroanthrachinon     werden in der     10-fachen    Menge Schwefel  säure gelöst, bei 10-201 mit<B>3,6</B> Teilen       Natriumnitrit    versetzt und 48 Stunden bei  Zimmertemperatur gerührt.  



  Die so erhaltene Lösung wird auf 400  Teile Eis aufgetragen, der kristallin abge  schiedene     Diazokörper    abgesaugt und mit       einer        zirka        40%igen        Schwefelsäure        gewa-          schen.    Der     Diazokörper    wird hierauf in<B>800</B>    Teilen Eiswasser gelöst, von eventuellen un  löslichen Anteilen     abfiltriert    und mit einer  Lösung von<B>5,5</B> Teilen     Resorein    in 200 Teilen  Wasser,<B>100</B> Teilen Eis und 40 Teilen kri  stallisiertem     Natriumacetat    vereinigt.

   Nach  mehrstündigem Rühren wird abgesaugt und  neutral gewaschen. Der so hergestellte     Nitro-          azokörper    bildet getrocknet ein dunkelbraunes  Pulver, das sich in konzentrierter Schwefel  säure braunrot, in     Toluol    braungelb löst.    Die feuchte Paste des Nitrokörpers wird  nun mit 200 Teilen Wasser verrührt und  mit<B>15</B> Teilen     Natriumsulfhydrat    während  1/2 bis<B>1</B> Stunde bei<B>60 '</B> nicht übersteigender  Temperatur behandelt. Hierauf wird abge  saugt, neutral gewaschen und gegebenenfalls  in bekannter Weise     verpastet.  



  Process for the production of a new dye. It has been found that a new dye is produced when 1-amino-4-nitro-anthraquinone is diazotized, then coupled with resorein and the product thus obtained is treated with reducing agents.



  The new dye forms a dark purple powder, which dissolves in concentrated sulfuric acid with a red-brown color and in toluene with a red-purple color. He colors the acetate silk in pure purple tones. <I> Example: </I> <B> 13.5 </B> parts of 1-amino-4-nitroanthraquinone are dissolved in 10 times the amount of sulfuric acid, for 10-201 with <B> 3.6 < / B> parts of sodium nitrite are added and the mixture is stirred for 48 hours at room temperature.



  The solution obtained in this way is applied to 400 parts of ice, the crystalline diazo bodies separated off with suction and washed with about 40% strength sulfuric acid. The diazo body is then dissolved in 800 parts of ice water, any insoluble constituents are filtered off and mixed with a solution of 5.5 parts resorein in 200 parts of water, 100 / B> parts of ice and 40 parts of crystallized sodium acetate combined.

   After several hours of stirring, it is filtered off with suction and washed neutral. The nitro azo body produced in this way forms a dark brown powder when dried, which dissolves brown-red in concentrated sulfuric acid and brown-yellow in toluene. The moist paste of the nitro body is then stirred with 200 parts of water and not more than <B> 15 </B> parts of sodium sulfhydrate for 1/2 to <B> 1 </B> hour at <B> 60 '</B> Temperature treated. This is followed by suction, washed neutral and, if necessary, pasted in a known manner.
