Description

  

  Verfahren zur Herstellung von     1.4-viaminoanthraehinon.       Es wurde gefunden, dass man     1.4-Di-          aminoanthrachinon    in vorteilhafter Weise  herstellen kann, wenn man auf     Dihydro-1.        4-          diaminoanthrachinon        1.4-Diiminoanthrachi-          non    einwirken     läss't.     



  <I>Beispiel:</I>  Zu einer Lösung von 23,4 Teilen 1     .4-          Diiminoanthrachinon    in 1000 Teilen 92 bis       93%iger    Schwefelsäure werden bei<B>90'</B> 23,8  Teile     Dihydro-1    .     4-diaminoanthrachinon    ein  getragen. Nach kurzer Zeit ist die Umsetzung  beendet, was daran zu erkennen ist, dass die  ursprünglich blutrote Farbe der Lösung ver-    schwindet. Hierauf wird auf Eis aufgetragen,  filtriert, mit Wasser gewaschen und getrock  net. Man erhält das 1     .4-Diaminoanthrachi-          non    in sehr reiner Form und mit vorzüglicher  Ausbeute.



  Process for the production of 1.4-viaminoanthraehinone. It has been found that 1,4-di-aminoanthraquinone can be produced in an advantageous manner if one uses dihydro-1. 4-diaminoanthraquinone 1,4-diiminoanthraquinone lets act.



  <I> Example: </I> To a solution of 23.4 parts of 1,4-diiminoanthraquinone in 1000 parts of 92 to 93% sulfuric acid, at <B> 90 '</B> 23.8 parts of dihydro-1. 4-diamond anthraquinone one worn. The reaction is over after a short time, which can be seen from the fact that the originally blood-red color of the solution disappears. It is then applied to ice, filtered, washed with water and dried. The 1,4-diaminoanthraquinone is obtained in a very pure form and with an excellent yield.
