Description

  

      Zusatzpatent    zum Hauptpatent Nr. 166223.    Verfahren zur Herstellung eines     1-Ogyalkylamino-4-aiylaminoanthrachinons.       Es wurde gefunden, dass man ein 1  Oxyalkylamino-4-arylaminoanthrachinon er  halten kann, wenn man auf 1     Mol        Leuko-          1.        4-di-(ss-oxyäthylamino)-anthrachinon    1     Mol          1-Amino-4-oxybenzol    einwirken lässt und das  so erhaltene     Kondensationsprodukt    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-OxyäIhylamino-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 ech  ten grünblauen Tönen.  



  <I>Beispiel:</I>  $ Teile     Leuko-l.        4-di-(ss-Oxyäthylamino)-          anthrachinon    werden in 35 Teilen     Butanol    mit    3.5 Teilen     1-Amino-4-oxybenzol,    0,7     Teilen    Na  triumchlorat und 2 Teilen Borsäure mehrere       Stunden    auf 95 bis<B>105'</B> erhitzt. Man destil  liert das     Butanol    teilweise ah,     filtriert    kalt,       wäscht        mit    Methanol und Wasser und  trocknet.



      Additional patent to main patent No. 166223. Process for the preparation of a 1-ogyalkylamino-4-aiylaminoanthraquinone. It has been found that a 1-oxyalkylamino-4-arylaminoanthraquinone can be obtained if 1 mole of 1-amino-4-oxybenzene is allowed to act on 1 mole of leuco-1,4-di- (ss-oxyäthylamino) anthraquinone and that 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-OxyäIhylamino-4-p-oxyphenylaminoanthraquinone 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 genuine green-blue tones.



  <I> Example: </I> $ Share Leuko-l. 4-di- (β-oxyäthylamino) - anthraquinone are trium chlorate in 35 parts of butanol with 3.5 parts of 1-amino-4-oxybenzene, 0.7 parts of sodium chlorate and 2 parts of boric acid for several hours to 95 to 105 '/ B > heated. The butanol is partially distilled off, filtered cold, washed with methanol and water and dried.
