  Zusatzpatent zum     Rauptpatent        Nr.   <B>108932.</B>    <B>V,</B> erfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden,     dass    man einen neuen  Farbstoff erhält, wenn man     6-Chlor-2,5-dik-          anilidobenzochinon    mit einer Lösung von  Chlor in     Schwef        eldichlorid,    entsprechend der       Zusa,mmeni;

  etzung        SCI"    und zwar im Ver  hältnis von<B>1</B>     Mol.        6-Chlor-2,5-dianilido-          benzochinon    zu<B>1</B>     Mol.        SCI"    bei höherer  Temperatur behandelt. Der neue Farbstoff  bildet ein rotbraunes Pulver, das sieh in kon  zentrierter Schwefelsäure mit rötlich violet  ter Farbe löst und Wolle aus der     Küpe    rot  braun färbt.

      <I>Beispiel<B>:</B></I>         3,3    Teile     6-Chlor-2,5-:dianilidobenzochi-          non    werden in etwa der     20-fachen    Menge  Nitrobenzol suspendiert und dann unter  Kühlung bei etwa<B>5</B> bis<B>10'</B> mit<B>1,8</B> Teilen  einer Lösung von Chlor in     Schwefeldichlo-          rid,    entsprechend der Zusammensetzung     Scl,     versetzt. Hierauf wird auf<B>100'</B> erhitzt und  das Gemisch einige Zeit bei dieser Tempera-         tur    belassen. Der neue Farbstoff wird sodann  kalt filtriert, mit Alkohol nachgewaschen  und getrocknet.

   Die Reaktion kann auch bei  Gegenwart von säurebindenden Mitteln, wie  Kreide,     Mg0    oder dergleichen durchgeführt  werden.



  Additional patent to main patent no. <B> 108932. </B> <B> V, </B> for the production of a new dye. It has been found that a new dye is obtained if 6-chloro-2,5-dikanilidobenzoquinone is mixed with a solution of chlorine in sulfur dichloride, corresponding to the combination;

  SCI "in the ratio of <B> 1 </B> mol. 6-chloro-2,5-dianilido-benzoquinone to <B> 1 </B> mol. SCI" treated at a higher temperature. The new dye forms a red-brown powder that dissolves in concentrated sulfuric acid with a reddish purple color and dyes wool from the vat red-brown.

      <I> Example <B>: </B> </I> 3.3 parts of 6-chloro-2,5-: dianilidobenzochinone are suspended in about 20 times the amount of nitrobenzene and then with cooling at about <B > 5 </B> to <B> 10 '</B> with <B> 1.8 </B> parts of a solution of chlorine in sulfur dichloride, corresponding to the composition Scl. It is then heated to <B> 100 '</B> and the mixture is left at this temperature for some time. The new dye is then filtered cold, washed with alcohol and dried.

   The reaction can also be carried out in the presence of acid-binding agents such as chalk, MgO or the like.
