  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 166223.    Verfahren zur Herstellung eines     1-Ogyalkylamino-4-aryla.minoanthrachinons.       Es wurde gefunden, dass man     ein        1-          Oxyalkylamino-4-arylaminoanthrachinon    er  halten kann, wenn man auf 1     Mol        Leuko-          1.    4 -     diamino    -     anthrachinon    1     Mol    1.

   4 -     Di-          aminobenzol    und 1     Mol    ss -     Oxyäthylamin          einwirken    lässt und das so erhaltene Konden  sationsprodukt oxydiert.  



  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-ss-Oxyäthylamino-4-p-phenylendi-          aminoanthraehinon    bildet ein dunkles Pul  ver, das sich in     Essigsäureäthylester        mit    grü  ner Farbe löst. Nach geeigneter     Verpastung     färbt es     Acetatkunstseide        in    vollen und ech  ten grünen Tönen.

      <I>Beispiel:</I>  60 Teile     Leuko-1    .     4-diaminoanthrachinon     werden     ii        \A00        Teilen        Pyridin    mit 30     Teilen            p-Phenylendiamin    und 16,5 Teilen     ss-Oxy-          äthylamin    einige Stunden auf 100   und dann  unter     Luftzutritt    zum Sieden erhitzt, bis das  gebildete Produkt oxydiert ist. Man fällt mit  Alkohol und     filtriert    kalt.



  <B> Additional patent </B> to main patent no. 166223. Process for the preparation of a 1-ogyalkylamino-4-aryla.minoanthraquinone. It has been found that a 1-oxyalkylamino-4-arylaminoanthraquinone can be obtained if 1 mole of 1 mole of leuco 1.

   4 - diaminobenzene and 1 mole of ss - oxyethylamine can act and the condensation product thus obtained is oxidized.



  The oxidation can be carried out by the separated condensation product being 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-ss-Oxyäthylamino-4-p-phenylenedi- aminoanthraehinon forms a dark powder that dissolves in ethyl acetate with a green color. After suitable pasting, it dyes acetate artificial silk in full and genuine green tones.

      <I> Example: </I> 60 parts of Leuko-1. 4-diaminoanthraquinone are 100 parts of pyridine with 30 parts of p-phenylenediamine and 16.5 parts of β-oxyethylamine for a few hours to 100 and then heated to boiling with admission of air until the product formed is oxidized. It is precipitated with alcohol and filtered cold.
