Description

  

  Verfahren zur     Darstellung    von     2-Aniinoantliraeliinon.       Es wurde gefunden, dass man     2-Amino-          anthrachinon    in guter Ausbeute aus     Anthra-          chinon-2-sulfosänre,        Ammoniak    und     Chlor-          caleium    dadurch gewinneu kann, dass man  diese Mischung unter Zusatz von Chlor  ammonium unter     Druck    erhitzt.

      <I>Beispiel:</I>  <B>100</B> Teile     Anthracltinort-2-sulfosaut-es          Natrium    werden mit 1000 Teilen konzen  triertem     wässrigem    Ammoniak (ca. 23      /oig),     60 Teilen kristallisiertem     Chlorealeium    und  100 Teilen Chlorammonium 7     Stunden    im       Autoklaven    auf<B>2050</B> erhitzt.

   Nach dein Erkal-         ten    wird der     Druckkesselinhalt        abfiltriert    und  der rote Kristallbrei     tnit        Wasser,        verdünnter          Salzsäure    und     Sodalüsung    nacheinander aus  gekocht. Das trockene Produkt ist dann  reines     2-Amitroanthrachinoti.    Ausbeute     i0 /o     der Theorie.



  Process for the preparation of 2-Aniinoantliraeliinon. It has been found that 2-amino-anthraquinone can be obtained in good yield from anthraquinone-2-sulfosene, ammonia and chlorocale by heating this mixture under pressure with the addition of chlorine ammonium.

      <I> Example: </I> <B> 100 </B> parts of Anthracltinort-2-sulfosaut-es sodium are mixed with 1000 parts of concentrated aqueous ammonia (approx. 23%), 60 parts of crystallized chlorealium and 100 parts of chlorammonium Heated for 7 hours in the autoclave to <B> 2050 </B>.

   After it has cooled down, the pressure vessel contents are filtered off and the red crystal paste is boiled out one after the other with water, dilute hydrochloric acid and soda solution. The dry product is then pure 2-amitroanthraquinoti. Yield i0 / o of theory.
