      Zusatzpatent    zum     ;Hauptpatent    Nr. 108932.    Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     6-Chlor-2,5-di-           <  < nilidobenzochinon    mit einer Lösung von  Chlor in     Schwefeldichlorid,    entsprechend der  Zusammensetzung     SCI"    und zwar im Ver  hältnis von 1     Mol.        6-Chlor-2,5-dianilido-          benzochinon    zu 3     Mol.        SCI"    behandelt.

    Der neue Farbstoff bildet ein rotbraunes  Pulver, das sich in konzentrierter Schwefel  säure mit bläulich violetter Farbe löst und  Wolle     aus    der     Küpe    gelbbraun färbt.         Beispiel            3,\3'    Teile     (i-Clilor-\?,5-dianilidoberizochi-          non    werden in     et-,va    der     20-fachen    Menge       Nitrobenzol    suspendiert und dann unter       Kühlung    bei etwa 5 bis 10   mit 5,3 Teilen       f,

  iner        Lösung    von Chlor in     Schwefeldichlo-          rid,        entsprechend    der Zusammensetzung     SCI"          @-@retzt.    worauf die Mischung einige Zeit       ührt    wird. Der neue Farbstoff wird    sodann kalt filtriert, mit Alkohol nachgewa  schen und getrocknet. Die Reaktion kann  auch bei Gegenwart von säurebindenden Mit  teln, wie Kreide,     Mg0    oder dergleichen durch  geführt werden.



      Additional patent to the main patent No. 108932. Process for the production of a new dye. It has been found that a new dye is obtained if 6-chloro-2,5-di- <<nilidobenzoquinone with a solution of chlorine in sulfur dichloride, corresponding to the composition SCI "in the ratio of 1 mol. 6- Chlor-2,5-dianilido-benzoquinone treated to 3 mol. SCI ".

    The new dye forms a red-brown powder that dissolves in concentrated sulfuric acid with a bluish purple color and dyes wool from the vat yellow-brown. Example 3, \ 3 'parts (i-Clilor - \ ?, 5-dianilidoberizochinon are suspended in about 20 times the amount of nitrobenzene and then with cooling at about 5 to 10 with 5.3 parts f,

  In a solution of chlorine in sulfur dichloride, corresponding to the composition SCI "@ - @, whereupon the mixture is stirred for some time. The new dye is then filtered cold, washed with alcohol and dried. The reaction can also take place in the presence of acid-binding agents With means such as chalk, Mg0 or the like can be performed.
