Description

  

  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 166223.         -Verfahren    zur Herstellung eines     1-Ogyalkylamino-4-arylaminoanthraehinons.       Es wurde gefunden, dass man ein     1-Oxy-          alkylarnino-4-arylaminoanthrachinon,    das 1-p       Oxyäthylainino-4-p-phenylendiaminoarithra-          chinon,    erhalten kann, wenn     man    auf 1     Mol          Leuko-1        -amino-4-(4'-aminophenyl)

  -amino-          anthrachinon    1     Mol        P-Oxyäthylamin    einwirken       läft    und das so erhaltene Kondensationspro  dukt oxydiert.  



  Die Oxydation kann durchgeführt werden,       indem    das abgeschiedene Kondensationspro  dukt in einem besonderen Arbeitsgange oxy  diert wird; man kann auch das Oxydations  mittel während der Kondensation zugeben,  es findet dann Oxydation unmittelbar nach       Kondensation    statt.  



  Das     1-ss-Oxyäthylamirio-4-p-pheriylendi-          aminoanthrachinon    bildet ein dunkles Pulver,  das sich in     Essigsäureäthylester    mit grüner  Farbe löst. Nach geeigneter     Verpastung    färbt  es     Acetatkunstseide    in vollen und echten  grünen Tönen.  



  <I>Beispiel:</I>  70 Teile     Leuko    -1-     amino    - 4 -     phenylendi-          aininoanthrachinon    werden mit 25 Teilen p-         Oxyäthylamin,    20 Teilen Borsäure und 7 Tei  len     Natriumchlorat    in 400 Teilen Methanol  einige     Stunden    zum Kochen erhitzt. Man fällt  den Farbstoff mit Benzol aus.



  <B> Additional patent </B> to main patent no. 166223. -Process for the production of a 1-ogyalkylamino-4-arylaminoanthraehinone. It has been found that a 1-oxyalkylarnino-4-arylaminoanthraquinone, the 1-p oxyäthylainino-4-p-phenylenediaminoarithra- quinone, can be obtained if one mole of leuco-1 -amino-4- (4 ' -aminophenyl)

  -amino- anthraquinone 1 mol of P-oxyäthylamine act runs and the condensation product thus obtained is oxidized.



  The oxidation can be carried out by the deposited condensation product is oxidized in a special operation; you can also add the oxidizing agent during the condensation, it then takes place oxidation immediately after condensation.



  The 1-ss-Oxyäthylamirio-4-p-pheriylenedi-aminoanthraquinone forms a dark powder which dissolves in ethyl acetate with a green color. After suitable pasting, it dyes acetate artificial silk in full and real green tones.



  <I> Example: </I> 70 parts of leuco -1-amino-4-phenylenedi- aininoanthraquinone are heated to boiling for a few hours with 25 parts of p-oxyethylamine, 20 parts of boric acid and 7 parts of sodium chlorate in 400 parts of methanol. The dye is precipitated with benzene.
