  Verfahren zur Herstellung eines neuen     Anthrachinonderivates.       Es wurde gefunden, dass man ein neues       Anthrachinonderivat    erhält, wenn man das       1,1'-Naphthylamino-        (2'-methoxy)-anthrachi-          non    mit sauren     Kondensationsmitteln    behan  delt. Als saure     Kondensationsmittel    kommen  in Frage Aluminiumchlorid oder Schwefel  säure.  



  Das neue     Anthrachinonderivat    bildet ein       dunkel-olivegrünes        Pulver,    das sich in kon  zentrierter Schwefelsäure mit brauner Farbe  löst. Durch Wasserzusatz scheiden sieh aus  dieser Lösung     olive-farbene    Flocken ab, die  aus roter     Hydrosulfitküpe    die Faser in ech  ten oliven Tönen färben.    <I>Beispiel:</I>  100 Teile Aluminiumchlorid werden mit  25 Teilen     Natriumchlorid    auf 140' geheizt  und in die     Schmelze    bei 140 bis 150   in  Portionen 10 Teile     1,1'-Naphthylamino-(2'-          methoxy)    -     anthrachinon    eingetragen.

   Man  hält die Schmelze 1/2     Stunden    bei 140 bis  <B>150,</B> trägt sie dann in verdünnte wässerige  Salzsäure     aus,    kocht auf,     wobei.    der Farb-         stoff    als     olivegrüne        Flocken    ausfällt. Nach  .dem Absaugen wäscht man mit     Wasser    und  trocknet. Man erhält ein     dunkel-olivegrünes     Pulver, das sich in     konzentrierter    Schwefel  säure mit brauner Farbe löst.

   Durch Was  serzusatz     scheiden    sich aus     dieser    Lösung       olivefarbene    Flocken ab, die aus roter     Hydro-          sulfitküpe    die Faser in     echten    oliven Tönen  färben.



  Process for the production of a new anthraquinone derivative. It has been found that a new anthraquinone derivative is obtained if the 1,1'-naphthylamino- (2'-methoxy) -anthraquinone is treated with acidic condensing agents. As acidic condensing agents, aluminum chloride or sulfuric acid can be used.



  The new anthraquinone derivative forms a dark olive green powder that dissolves in concentrated sulfuric acid with a brown color. With the addition of water, olive-colored flakes separate from this solution, which from the red hydrosulfite vat color the fiber in real olive tones. <I> Example: </I> 100 parts of aluminum chloride are heated to 140 'with 25 parts of sodium chloride and 10 parts of 1,1'-naphthylamino- (2'-methoxy) anthraquinone are introduced into the melt at 140 to 150 in portions.

   The melt is kept at 140 to 150 for 1/2 hour, it is then poured out in dilute aqueous hydrochloric acid, and it is boiled. the dye precipitates as olive-green flakes. After suctioning off, wash with water and dry. A dark olive-green powder is obtained which dissolves in concentrated sulfuric acid with a brown color.

   When water is added, olive-colored flakes separate out of this solution, which dye the fibers in real olive tones from the red hydrosulfite vat.
