Description

  

      Zusatzpatent    zum     Hauptpatent    Nr. 166223.         Verfahren    zur Herstellung eines     1-Oxyalkylamino-4-arylitminoanthrachinons.       Es wurde gefunden, dass man ein     1-Oxyal-          kylarnirio-4-ai#ylamirioarithrachinon    erhalten  kann, wenn man auf 1     Mol        Leuko-1.4-di-(ss-          oxyäthylamino)-anthrachinon    1     Alol        1.4-Di-          aminobenzol    einwirken lässt und das so er  haltene Kondensationsprodukt oxydiert.  



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



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



  <I>Beispiel 1:</I>  6 Teile     Leuko-1.4-di(ss-oxyäthylamino)-          anthrachinon    werden in 30 Teilen Äthanol mit    2 Teilen     p-Phenylendiamin    und 1 Teil     p-Phe-          nylendiaminchlorhydrat    einige Stunden zum  Sieden erhitzt. Das gebildete Produkt wird  filtriert und in üblicher Weise oxydiert.    <I>Beispiel 2:</I>    8 Teile     Leuko-1.4-di(ss-oxyäthylamino)-          anthrachinon    werden in 35 Teilen     Methanol     mit 3 Teilen     1.4-Diaminobenzol,    0,7 Teilen       Natriumchlorat    und 2 Teilen Borsäure mehrere  Stunden auf 65   erhitzt.

   Man filtriert kalt,  wäscht mit Methanol und Wasser und erhält  in guter Ausbeute und Reinheit     1-p-Oxyäthyl-          amino-4-p-pheriylendiaminoanthrachirion.  



      Additional patent to main patent No. 166223. Process for the preparation of a 1-oxyalkylamino-4-arylitminoanthraquinone. It has been found that a 1-oxyalkylarnirio-4-ai # ylamirioarithraquinone can be obtained if 1 mol of leuco-1,4-di- (ss- oxyäthylamino) -anthraquinone 1 alol 1,4-diaminobenzene is allowed to act and that so he obtained condensation product 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, then oxidation takes place immediately after the condensation.



  The 1-ss-oxyethylamino-4-p-phenylenediaminanthraquinone 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 1: </I> 6 parts of leuco-1,4-di (ss-oxyethylamino) anthraquinone are heated to boiling for a few hours in 30 parts of ethanol with 2 parts of p-phenylenediamine and 1 part of p-phenylenediamine chlorohydrate. The product formed is filtered and oxidized in the usual way. Example 2: 8 parts of leuco-1,4-di (ss-oxyethylamino) anthraquinone are heated to 65 for several hours in 35 parts of methanol with 3 parts of 1,4-diaminobenzene, 0.7 parts of sodium chlorate and 2 parts of boric acid .

   It is filtered cold, washed with methanol and water and 1-p-oxyethylamino-4-p-pheriylenediaminoanthrachirione is obtained in good yield and purity.
