Description

  

      Zusatzpatent    zum Hauptpatent Nr. 187125.    Verfahren zur Herstellung eines neuen     Anthrachinonderivates.       Es wurde     gefunden,    dass man ein neues       Anthrachinonderivat        -erhält,        wenn    man das       1,1'-Naplithylamino-        (2'-methoxy)-4-benzoyl-          aminoanthrachinon    mit sauren     Ko#ndensa-          tionsmitteln    behandelt. Als saure     Konden-          sationsmittel    kommen in Frage Schwefel  säure oder Aluminiumchlorid.  



       Das    neue     Anthrachinonderivat    bildet ein       dunkel-olivegrünes    Pulver, das sich in     konz.     Schwefelsäure mit oranger Farbe löst,     aus     welcher Lösung durch Eintragen in Wasser       bräunlich--live    Flocken abgeschieden wer  den.

   Durch     alkalische        Hydrosulfitküpe    wird  eine     blaustichig        rote    Lösung     ,erhalten,    aus  der Baumwolle in     gelblich-grünen,    echten  Tönen angefärbt     wird..       <I>Beispiel:

  </I>    10 Teile     des    1,1' -     Naphthylamino    - (2'     -          methoxy)-4-benzoylaminoanthrachinons    wer  den in 150 Teilen Schwefelsäure<B>661</B>     B6    bei  10     bis        211      mehrere     Stunden        gerührt.    Die       Lösung        wird    dann auf Eis ausgetragen, und         die        abges,chi:edenen    Flocken werden abge  saugt.

   Nachdem Waschen mit Wasser und       Trocknen    erhält man ein     dunkel-olives    Pul  ver,     wähmend,das        Ausgangsprodukt    eine     dun-          kelblaue        Farbe    zeigt.



      Additional patent to main patent no. 187125. Process for the production of a new anthraquinone derivative. It has been found that a new anthraquinone derivative is obtained when the 1,1'-naplithylamino- (2'-methoxy) -4-benzoylaminoanthraquinone is treated with acidic co-solvents. Acidic condensation agents that can be used are sulfuric acid or aluminum chloride.



       The new anthraquinone derivative forms a dark olive-green powder, which is in conc. Sulfuric acid with an orange color dissolves, from which solution brownish - live flakes are deposited by adding it to water.

   Using an alkaline hydrosulfite vat, a bluish red solution is obtained from which cotton is dyed in yellowish-green, real shades. <I> Example:

  10 parts of 1,1'-naphthylamino (2'-methoxy) -4-benzoylaminoanthraquinone are stirred in 150 parts of sulfuric acid B6 at 10 to 211 for several hours. The solution is then poured onto ice, and the chi: edenen flakes are sucked off.

   After washing with water and drying, a dark olive powder is obtained, while the starting product shows a dark blue color.
