Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 108932.    Verfahren zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     2,5-Dianilido-          toluchinon    mit einer Lösung von Chlor  in     Schwefeldichlorid,    entsprechend der Zu  sammensetzung     SC13,    und zwar im Verhält  nis von 1 Hol.     2,5-Dianilidotoluchinon    zu  2 Hol.     SCl3,    behandelt. Der neue Farbstoff  bildet ein rotbraunes Pulver, das sich in kon  zentrierter .Schwefelsäure mit     trübvioletter     Farbe löst und Wolle aus der     Küpe    rötlich  braun färbt.  



  <I>Beispiel</I>  6,08 Teile     2,5-Dianilidotoluchinon    wer  den in etwa der 20fachen Menge Nitrobenzol  suspendiert und dann unter Kühlung bei  etwa 5 bis<B>10'</B> mit 5,6 Teilen einer Lösung  von Chlor in     Schwefeldichlorid,    entsprechend  der Zusammensetzung     SC13,    versetzt, worauf  die Mischung einige Zeit gerührt wird.    Der neue Farbstoff wird sodann kalt fil  triert, mit Alkohol nachgewaschen und ge  trocknet. Die Reaktion kann auch bei Gegen  wart von säurebindenden Mitteln, wie Kreide,       Mg0    oder dergleichen, durchgeführt werden.



  <B> Additional patent </B> to main patent no. 108932. Process for the production of a new dye. It has been found that a new dye is obtained if 2,5-dianilidotoluchinone is added to a solution of chlorine in sulfur dichloride, corresponding to the composition SC13, in a ratio of 1 Hol. 2,5-dianilidotoluchinone at 2 hol. SCl3, treated. The new dye forms a red-brown powder that dissolves in concentrated sulfuric acid with a cloudy purple color and dyes wool from the vat reddish brown.



  <I> Example </I> 6.08 parts of 2,5-dianilidotoluchinone are suspended in about 20 times the amount of nitrobenzene and then, with cooling, at about 5 to 10 'with 5.6 parts of a solution of chlorine in sulfur dichloride, corresponding to the composition SC13, is added, after which the mixture is stirred 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.
