Description

  

  Verfahren zur Darstellung eines als     Farbstoff    und     Farbstoffzwischenprodukt     verwendbaren     Kondensationsproduktes    der     Anthrachinonreihe.       Es     -wurde    gefunden, dass man ein neues,  als Farbstoff und     Farbstoffzwischenprodukt          verwendbares    Kondensationsprodukt der     An-          thrachinonreilie    erhält, wenn man     Cyanur-          chlorid    und     1.5-Diaminoanthrachinon    mit  einander umsetzt, und zwar unter Anwendung  von über einem Molekül des letzteren auf je  ein Molekül des ersteren.

           Beispiel:       72 Teile     1.5-Diaminoanthrachinon,   <B>18</B>       'feile        Cyanurchlorid    werden in     Nitrotoluol     <B>. f</B> 190 bis 195   erwärmt, etwa eine Stunde.

         #    au  bei dieser Temperatur gehalten und dann       w        ährend        L        etwa        12        Stunden        bis        z        11        m        Sieden     des     Nitrotoluols    erhitzt.

   Nach Abkühlen der  Reaktionsmasse wird filtriert, das zurück  bleibende     Kondensationsprodukt    mit     Nitro-          tohzol,    sowie Alkohol     gej;-a        sclieri    und wenn  nötig noch einer Reinigung unterzogen.

    Trocken stellt es ein rotbraunes Pulver dar,  ist unlöslich in Wasser, wenig löslich in kal  tem und heissen- Alkohol, desgleichen in kal  tem Chlorbenzol, mässig löslich in heissem         Chlorbenzol    und kaltem     Nitrobenzol    und  mit     braunroter        Farbe.        Seine    Lösung in kal  ter konzentrierter Schwefelsäure ist     braun;          beim        -\Terküpen        desselben    wird eine braune       Lösung    erhalten, aus der Baumwolle sich in  rotbraunen Tönen     anfärben        li@.sst.  



  Process for the preparation of a condensation product of the anthraquinone series which can be used as dye and dye intermediate. It has been found that a new condensation product of the anthrachinone line which can be used as a dye and dye intermediate is obtained if cyanuric chloride and 1,5-diaminoanthraquinone are reacted with one another using more than one molecule of the latter for one molecule each the former.

           Example: 72 parts of 1,5-diaminoanthraquinone, <B> 18 </B> 'file cyanuric chloride are in nitrotoluene <B>. f 190 to 195 heated, about an hour.

         # is kept at this temperature and then heated for about 12 hours to about 11 m boiling of the nitrotoluene.

   After the reaction mass has cooled, it is filtered, the remaining condensation product with nitro-tohzol and alcohol gej; -a sclieri and, if necessary, subjected to purification.

    When dry, it is a red-brown powder, is insoluble in water, slightly soluble in cold and hot alcohol, also in cold chlorobenzene, moderately soluble in hot chlorobenzene and cold nitrobenzene and has a brownish-red color. Its solution in cold concentrated sulfuric acid is brown; with the vat of the same a brown solution is obtained, from which cotton can be dyed in red-brown tones.
