Description

  

      Zusatzpatent    zum Hauptpatent Nr. 166790.    Verfahren     zur    Darstellung eines neuen     Farbstoffes    der     Anthraehinonreihe.       Das vorliegende Verfahren betrifft die  Darstellung eines neuen Farbstoffes der An  thrachinonreihe und ist dadurch gekennzeich  net,     da.ss    man     1-Amino-4-p-toIuidoa,nthraehi-          non-2-sulfosäure    mit Salpetersäure behandelt.  <I>Beispiel:</I>  8,6 Teile     1-amino-4-p-toluidoanthrachinon-          2-sulfosaures    Natrium werden in 50 Teilen  Monohydrat gelöst und bei einer Temperatur  um 0   mit 5,2 Teilen Mischsäure<B>50%</B> be  handelt.

   Zum Beenden der Reaktion erwärmt  man auf 50  .  



  Der Farbstoff löst sich in Wasser rötlich  braun und in     Schwefelsäure    gelb. Er stellt    einen grauschwarzen Körper dar und färbt  tierische Faser in     braunbeigen    Tönen an.



      Additional patent to main patent no. 166790. Process for the preparation of a new dye of the anthraehinone series. The present process relates to the preparation of a new dye of the anthrachinone series and is characterized in that 1-amino-4-p-toiuidoa, nthraehinon-2-sulfonic acid is treated with nitric acid. <I> Example: </I> 8.6 parts of 1-amino-4-p-toluidoanthraquinone-2-sulfonic acid sodium are dissolved in 50 parts of monohydrate and mixed with 5.2 parts of mixed acid at a temperature of around 0%. </B> treated.

   To end the reaction, the mixture is heated to 50.



  The dye dissolves reddish brown in water and yellow in sulfuric acid. It represents a gray-black body and stains animal fibers in brown-beige tones.
