Description

  

  verfahren zur Herstellung eines neuen     Anthrachinonderivates.       Es wurde gefunden, dass man ein neues       Anthrachinonderivat    erhält, wenn man 1-ss  Oxyäthylamino-4-methoxyanthrachinon mit  Anilin umsetzt, wobei 1     Mol    Anilin mit einem       Mol    des     Anthrachinonderivates    reagiert.  



  Der Farbstoff bildet ein dunkles Pulver,  löst sich in organischen Lösungsmitteln mit  blauer Farbe und färbt     Acetatseide    nach ge  eigneter.     Verpastung    in reinen blauen Tönen.  Durch     Sulfieren    erhält man einen wertvollen  Wollfarbstoff.  



  <I>Beispiel:</I>  63 Teile     1-p-Oxyäthylamino-4-methoxy-          anthrachinon    werden in 250 Teilen Anilin  ca. 42 Stunden auf 160-180<B>'</B>erwärmt. Man  fällt mit 350 Teilen Methylalkohol und erhält  in vorzüglicher Reinheit ein Produkt, welches         Acetatseide    nach geeigneter     Verpastung    in  reinen, blauen Tönen färbt.



  process for the production of a new anthraquinone derivative. It has been found that a new anthraquinone derivative is obtained if 1-ss oxyethylamino-4-methoxyanthraquinone is reacted with aniline, 1 mol of aniline reacting with one mol of the anthraquinone derivative.



  The dye forms a dark powder, dissolves in organic solvents with a blue color and dyes acetate silk as appropriate. Pasting in pure blue tones. A valuable wool dye is obtained by sulfating.



  <I> Example: </I> 63 parts of 1-p-oxyethylamino-4-methoxy-anthraquinone are heated in 250 parts of aniline for about 42 hours to 160-180 <B> '</B>. It is precipitated with 350 parts of methyl alcohol and a product is obtained in excellent purity which, after suitable pasting, dyes acetate silk in pure, blue shades.

PATENTANSPRUCH Verfahren zur Darstellung von l-p-Oxy- äthylamino-4-phenylaminoanthrachinon, da durch gekennzeichnet, dass man auf 1-ss-Oxy- äthylamino-4-methoxyanthrachinon Anilin bei erhöhter Temperatur einwirken lässt. Der Farbstoff bildet ein dunkles Pulver, löst sich in organischen Lösungsmitteln mit blauer Farbe und färbt Acetatseide nach geeigneter Verpastung in reinen, blauen Tönen. Durch Sulfieren erhält man einen wertvollen Wollfarbstoff. PATENT CLAIM Process for the preparation of l-p-oxyethylamino-4-phenylaminoanthraquinone, characterized in that aniline is allowed to act on 1-ss-oxyethylamino-4-methoxyanthraquinone at elevated temperature. The dye forms a dark powder, dissolves in organic solvents with a blue color and, after suitable pasting, dyes acetate silk in pure, blue tones. A valuable wool dye is obtained by sulfating.
