Description

  

  Verfahren zur Darstellung eines neuen     Farbstoffes    der     Anthrachinonakridonreihe.       Es wurde gefunden, dass man einen neuen  Farbstoff der     Anthrachinonakridonreihe    er  halten kann, wenn man 3'.     5'-Dichloranthra-          chinonakridon,    das aus dem Kondensations  produkt aus     1-Chloranthrachinon-2-carbon-          säurebenzylester    und     m-Dichloranilin    durch  Behandeln mit Wasser entziehenden Mitteln  hergestellt werden kann, mit einem     chlorie-          rend    wirkenden     Mittel    behandelt.  



  Der erhaltene Farbstoff, der Analyse  nach ein     Pentachloranthrachinonakridon,     löst sich in     konzentrierter    Schwefelsäure mit  orangeroter Farbe und liefert eine violette       Küpe,    aus der Baumwolle in leuchtenden  blaustichigen     Rosatönen    gefärbt wird.  



  <I>Beispiel:</I>  Zu einer Suspension von 13 Teilen 3'. 5'  Dichloranthrachinonakridön, erhalten zum  Beispiel aus dem Kondensationsprodukt aus    1 -     Chloranthrachinon    - 2 -     carbonsäurebenzyl-          ester    und     m-Dichloranilin    durch Behandeln  mit Wasser entziehenden Mitteln, in 250  Teilen trockenem Nitrobenzol werden nach  Zugabe von 0,7 Teilen Jod bei 90 bis 100   C  30 Teile     Sulfurylchlorid    allmählich hinzu  gefügt. Man rührt zirka 4 Stunden lang bei  der gleichen Temperatur, saugt darnach die  abgekühlte Reaktionsmasse ab und arbeitet  in der üblichen Weise auf.



  Process for the preparation of a new dye of the anthraquinone acridone series. It has been found that you can hold a new dye of the anthraquinone acridone series if you 3 '. 5'-dichloroanthraquinonakridone, which can be prepared from the condensation product of 1-chloroanthraquinone-2-carboxylic acid benzyl ester and m-dichloroaniline by treatment with dehydrating agents, treated with a chlorinating agent.



  The dye obtained, which is analyzed according to a pentachloroanthraquinone acridone, dissolves in concentrated sulfuric acid with an orange-red color and yields a violet vat from which cotton is dyed in bright blue-tinged pink tones.



  <I> Example: </I> For a suspension of 13 parts 3 '. 5 'dichloroanthraquinone acridone, obtained for example from the condensation product of 1 - chloroanthraquinone - 2 - carboxylic acid benzyl ester and m-dichloroaniline by treatment with dehydrating agents, in 250 parts of dry nitrobenzene after adding 0.7 part of iodine at 90 to 100 ° C 30 parts of sulfuryl chloride were gradually added. The mixture is stirred for about 4 hours at the same temperature, then the cooled reaction mass is suctioned off and worked up in the usual way.
