Description

  

  Zusatzpatent zum Hauptpatent Nr. 166223.    Verfahren zur Herstellung eines     1-Ogyalkylamino-4-arylaminoanthrachinons.       Es wurde gefunden, dass man ein     1-Oxy-          alkylarnino-4-arylamirroant@r#aclrirron,    das 1-ss       Oxyäthylamino-4-(p-oxyphenyl)-arninoanthr,a-          chinon,    erhalten kann, wenn man auf 1     Mol          Lerrko-l-oxy        -4-i3-oxyäthylamirroarrthrachinon     1     Mol        p-Arninopheirol    einwirken lässt und das  so erhaltene Kondensationsprodukt 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-p-Oxyäthylamino-4-(p-oxyphenyl)-          aminoanthrachinon    bildet ein dunkles Pulver,  das sich in     Essigsäureäthylester    mit grün  blauer Farbe löst. Nach geeigneter     Verp        astung     färbt es     Acetatkunstseide    in vollen und echten       grünblauen        Tönen.     



  <I>Beispiel:</I>  30 Teile     Leuko-l-oxy-4-p-oxyäthylamino-          anthrachinon    und 30 Teile 1-Oxy-4-ss-oxy-         äthylaminoarrthrachinon    werden in 300 Teilen       Äthanol    mit 25 Teilen     p-Aminophenol    und  10 Teilen Borsäure einige Stunden bei Luft  zutritt zum Kochen erhitzt. Man fällt den       Farbstoff    mit Benzol aus.



  Additional patent to main patent No. 166223. Process for the preparation of a 1-ogyalkylamino-4-arylaminoanthraquinone. It has been found that a 1-oxyalkylarnino-4-arylamirroant @ r # aclrirron, the 1-ss oxyäthylamino-4- (p-oxyphenyl) -arninoanthr, a-quinone, can be obtained if one mole of Lerrko -l-oxy -4-i3-oxyäthylamirroarrthraquinone allows 1 mol of p-aminopheirol to act and oxidizes the condensation product thus obtained.



  The oxidation can be carried out in that 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-p-Oxyäthylamino-4- (p-oxyphenyl) - aminoanthraquinone forms a dark powder, which dissolves in ethyl acetate with a green-blue color. After suitable pasting, it dyes acetate artificial silk in full and genuine green-blue tones.



  <I> Example: </I> 30 parts of leuco-l-oxy-4-p-oxyethylamino-anthraquinone and 30 parts of 1-oxy-4-ss-oxy-ethylaminoarrthraquinone are in 300 parts of ethanol with 25 parts of p-aminophenol and 10 parts boric acid heated to boiling for a few hours with access to air. The dye is precipitated with benzene.

PATENTANSPRUCH: Verfahren zur Herstellung eines 1-Oxy- alkylamino-4-arylaminoanthraehinons, des 1-ss Oxyäthylamino-4-(p-oxyphenyl)-arninoanthr,a- chinons, dadurch gekennzeichnet, dass man auf 1 Mol Leuko-l-oxy-4-ss-oxyäthylamino- anthrachinon 1 Mol p-Aminophenol einwirken lässt und das so erhaltene Kondensationspro dukt oxydiert. PATENT CLAIM: Process for the preparation of a 1-oxyalkylamino-4-arylaminoanthraehinons, the 1-ss oxyäthylamino-4- (p-oxyphenyl) -arninoanthr, a-quinones, characterized in that one mole of leuco-l-oxy 4-ss-oxyäthylamino- anthraquinone 1 mole of p-aminophenol can act and the condensation product thus obtained is oxidized. Das 1-ss-Oxyäthylamino-4-(p-oxypheriyl)- aminoanthrachinon bildet ein dunkles Pulver, das sich in Essigsäureäthylester mit grün blauer Farbe löst. Nach geeigneter Verpastung färbt es Acetatkunstseide in vollen und echten grünblauen Tönen. The 1-ss-Oxyäthylamino-4- (p-oxypheriyl) - aminoanthraquinone forms a dark powder that dissolves in ethyl acetate with a green-blue color. After suitable pasting, it dyes acetate artificial silk in full and real green-blue tones.
