  Verfahren zur Darstellung von Küpenfarbstoffen der Anthrazenreihe. 



   In der deutschen Patentschrift Nr. 136015 ist gezeigt worden, dass   2-Aminoanthra-   chinon beim Erhitzen mit wasserfreiem Aluminiumchlorid   FJavanthren   bildet. 



   Nach der   deutschen Patentschrift Nr.   206464 erhält man bei der Einwirkung von Aluminiumchlorid auf   2-Aminoanthrachinon   bei Gegenwart von Nitrobenzol einen rötlichbraunen Küpenfarbstoff. 



   Aus der deutschen Patentschrift Nr. 186637 geht hervor, dass 1-Aminoanthrachinon beim Erhitzen mit Aluminiumchloridlösung in Indanthren   übergeht.   



   Es wurde gefunden, dass auch andere Derivate des Anthrachinons, z. B. die Chlorund die Rhodananthrachinone, ferner das Anthrachinon selbst und seine Homologen beim Erhitzen mit wasserfreiem   A1uminiumchlorid   echte   Küpenfarbstoffe   liefern. 



   Selbst   Anthrachinonsulfosauren   reagieren in Form ihrer Salze mit   sub1imiertem   
 EMI1.1 
   Dunkoifärbung   und entwickelt unter Schäumen Salzsäure. Die Reaktion ist beendet, sobald die Masse erstarrt. 



   Das erhaltene schwarze Farbstoffpulver kann mit Salzsäure gereinigt oder direkt als Farbstoffverwendetwerden. 



   Es gibt mit alkalischer Hydrosulfitlösung eine schwarzviolette Küpe, aus der Baum-   wolle in braunen Tonen angefärbt wird.

  Process for the preparation of vat dyes of the anthracene series.



   In the German patent specification No. 136015 it has been shown that 2-aminoanthraquinone forms FJavanthrene when heated with anhydrous aluminum chloride.



   According to German Patent No. 206464, the action of aluminum chloride on 2-aminoanthraquinone in the presence of nitrobenzene gives a reddish-brown vat dye.



   German Patent No. 186637 shows that 1-aminoanthraquinone changes to indanthrene when heated with aluminum chloride solution.



   It has been found that other derivatives of anthraquinone, e.g. B. the chlorine and the rhodananthraquinones, furthermore the anthraquinone itself and its homologues when heated with anhydrous aluminum chloride provide real vat dyes.



   Even anthraquinone sulphonic acids react in the form of their salts with sublimed ones
 EMI1.1
   Darkening and developing hydrochloric acid with foaming. The reaction is over as soon as the mass solidifies.



   The obtained black dye powder can be purified with hydrochloric acid or used directly as a dye.



   There is a black-violet vat with an alkaline hydrosulphite solution, from which cotton is dyed in brown tones.



  H e i s p i e I II.
 EMI1.2
 Coloring on cotton is bronze zebra.



   Some dyes that can be produced by this process are described in the table below:
