Description

  

      Verfahren    zur Darstellung eines     Farbstoffes.       Es wurde gefunden, dass eine als Pig  ment-, wie als     Küpenfarbstoff    von     hervor-          ragcn.den    Echtheitseigenschaften benutzbare  Verbindung erhalten wird, wenn man das  durch Kondensation von     2.3-Dichlor-1.4-          naplitochinon    mit     1.2-Diamino-4-methylben-          zol    erhältliche     Eurhodol    mit 2 .     3-Dic-hlor      1 .

       4-naplitochinon    bei Gegenwart von Metal  len und eines     salzsäurebindenden    Mittels er  hitzt.  



  <I>Beispiel:</I>  28,5 Teile des     Eurhodols,    erhalten aus  2 .     3-Dialilor-1    .     4-naphtochinon    und 1.     3-Dia-          niino-4-rrietliylben7ol    werden mit 23 Teilen  2 . ; -     Dichlor-1    . 4 -     naphtochinon,    15 Teilen       wasserfreiem        Natriumacetat,    12 Teilen Kup  ferbronze und 80 Teilen     Nitrobenzol    auf 140    erhitzt. Das Lösungsmittel wird mit Dampf    abgeblasen. Der gereinigte und vom Kupfer  befreite, gelbe Farbstoff färbt Baumwolle aus  der     Hydrosulfitküpe    gelb.



      Process for the preparation of a dye. It has been found that a compound which can be used as a pigment or as a vat dye with excellent fastness properties is obtained if the compound obtained by condensation of 2,3-dichloro-1,4-naplitoquinone with 1,2-diamino-4-methylbenzene is obtained Eurhodol with 2. 3-Dic-hlor 1.

       4-naplitoquinone in the presence of metals and a hydrochloric acid binding agent it heats.



  <I> Example: </I> 28.5 parts of the Eurhodol, obtained from 2. 3-dialilor-1. 4-naphthoquinone and 1. 3-dianiino-4-rrietliylben7ol are mixed with 23 parts of 2. ; - dichloro-1. 4 - naphthoquinone, 15 parts of anhydrous sodium acetate, 12 parts of copper ferbronze and 80 parts of nitrobenzene heated to 140. The solvent is blown off with steam. The yellow dye, which has been cleaned and freed from copper, dyes cotton from the hydrosulfite vat yellow.
