Description

  

  Verfahren zur     Herstellung    eines     1-Ozyalxylamino-4:-arylaminoanthracliinons.       Es wurde gefunden, dass man     ein        1-          Oxyalkylamino-4-arylaminoanthrachinon    er  halten kann, wenn man auf 1     Mol        Leuko-          1.    4 -     di    - (p -     ogyphenyl)

      -     aminoanthrachinon     1     'Mol        /3-Oxyäthylamin        einwirken        lässt    ' und  das so     erhaltene    Kondensationsprodukt oxy  diert.  



  Die Oxydation kann durchgeführt wer  den, indem das abgeschiedene     Kondensations-          produkt    in einem besonderen Arbeitsgange  oxydiert wird; man kann auch das Oxyda  tionsmittel während der Kondensation zu  geben; es findet dann Oxydation unmittelbar  nach Kondensation statt.  



  Das     1-,B-Oxyäthylamino-4-(p-oxyphenyl)-          aminoanthrachinon    bildet ein dunkles Pul  ver, das sich in     Essigsäureäthylester    mit grün  blauer Farbe löst. Nach     geeigneter        Verpastung     färbt es.     Acetatkunstseide        in    vollen und erb  ten grünblauen Tönen.  



  <I>Beispiel:</I>  8,6     TeilcLeuko-l.4-di-(p-oxyphenyl)-amino-          ithrachinon    werden in 40     Teilen        Pyridin       mit 1,25 Teilen     ss-Oxyäthylamin    mehre       Stunden    unter     Luftabschluss    auf 95 bis 120  erwärmt.     Hierauf    erwärmt man noch einig  Zeit unter Luftzutritt weiter, wobei     da     entstandene     Kondensationsprodukt        oxydie     wird.



  Process for the preparation of a 1-Ozyalxylamino-4: -arylaminoanthracliinons. It has been found that a 1-oxyalkylamino-4-arylaminoanthraquinone can be obtained if 1 mole of leuco 1. 4 - di - (p - ogyphenyl)

      - Aminoanthraquinone 1 'mol / 3-oxyethylamine can act' and the resulting condensation product is oxidized.



  The oxidation can be carried out in that the separated condensation product is oxidized in a special operation; you can also give the Oxyda tion agent during the condensation; oxidation then takes place immediately after condensation.



  The 1-, B-oxyäthylamino-4- (p-oxyphenyl) - aminoanthraquinone forms a dark powder that dissolves in ethyl acetate with a green-blue color. After suitable pasting, it stains. Acetate artificial silk in full and inherited green-blue tones.



  <I> Example: </I> 8.6 parts of leuko-1.4-di- (p-oxyphenyl) -amino-ithraquinone in 40 parts of pyridine with 1.25 parts of ß-oxyethylamine are heated to 95 to 120 for several hours in the absence of air warmed. Then the heating is continued for some time with the admission of air, the resulting condensation product becoming oxidized.
