Description

  

  Verfahren zur Herstellung eines neuen     Anthrachinonderivates.       Es wurde gefunden, dass man einen wert  vollen neuen     Acetatkunstseidefarbstoff    erhält,  wenn man auf     1-Amino-4-p-oxyphenylamino-          anthrachinon        Äthylenoxyd    einwirken lässt,  wobei ein     Mol        Äthylenoxyd    mit einem     Mol     des     Anthrachinonderivates    reagiert.

   Der er  haltene Farbstoff bildet ein dunkles Pulver,  löst sich in Alkohol mit blauer Farbe und  färbt     Acetatkunstseide    nach geeigneter     Ver-          pastung    in kräftigen grünblauen Tönen.    <I>Beispiel:</I>    50 Teile     1-Amino-4-p-oxyphenylaniino-          anthrachinon    werden in 400 Teilen einer  20     o/oigen    Lösung von     Äthylenoxyd    in Eis  essig bei 50-60 o mehrere Stunden verrührt.  Man destilliert das Lösungsmittel ab, nimmt  mit Wasser auf und filtriert das     1-p-Oxy-          äthylamino-4-p-oxyphenylaminoanthrachinon       ab.

   Dieses färbt     Acetatkunstseide    nach ge  eigneter     Verpastung    in kräftigen grünblauen  Tönen. Man kann gegebenenfalls auch mit  andern Verdünnungsmitteln unter Druck ar  beiten.



  Process for the production of a new anthraquinone derivative. It has been found that a valuable new acetate rayon dye is obtained if ethylene oxide is allowed to act on 1-amino-4-p-oxyphenylamino-anthraquinone, one mole of ethylene oxide reacting with one mole of the anthraquinone derivative.

   The dye obtained forms a dark powder, dissolves in alcohol with a blue color and, after suitable pasting, colors acetate silk in strong green-blue tones. <I> Example: </I> 50 parts of 1-amino-4-p-oxyphenylaniino-anthraquinone are stirred in 400 parts of a 20% solution of ethylene oxide in glacial acetic acid at 50-60 ° for several hours. The solvent is distilled off, taken up in water and the 1-p-oxyethylamino-4-p-oxyphenylaminoanthraquinone is filtered off.

   This colors acetate artificial silk in strong green-blue tones after suitable pasting. You can optionally work with other diluents under pressure ar.

PATENTANSPRUCH: Verfahren zur Darstellung von 1-p-Oxy- äthylamino - 4-p-oxyphenylaminoanthrachinon, dadurch gekennzeichnet, dass man Äthylen oxyd auf 1-Amino-4-p-oxyphenylaminoanthra- chinon einwirken lässt. Der erhaltene Farbstoff bildet ein dunkles Pulver, löst sich in Alkohol mit blauer Farbe und färbt Acetatkunstseide nach geeigneter Verpastung in kräftigen grünblauen Tönen. PATENT CLAIM: A process for the preparation of 1-p-oxyethylamino - 4-p-oxyphenylaminoanthraquinone, characterized in that ethylene oxide is allowed to act on 1-amino-4-p-oxyphenylaminoanthraquinone. The dye obtained forms a dark powder, dissolves in alcohol with a blue color and, after suitable pasting, dyes acetate artificial silk in strong green-blue tones.
