Description

  

  <B>Zusatzpatent</B>     zum    Hauptpatent Nr. 208545.    Verfahren zur Herstellung eines     Anthraehinonderivates.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines neuen  Wollfarbstoffes der     Anthrachinonreihe,    wel  ches dadurch gekennzeichnet ist,

   dass man  das     Anthrimid    aus     1-p-Anisidino-4-amino-          arrthrachinon    und     1-Halogen-4-methoxyarrthra-          chinon        mit        Oleum        von    3     bis    5     %        Anhydrid-          gehalt    bei einer Temperatur von 15 bis  20 0 C ungefähr eine halbe Stunde behandelt.  Man erhält auf diese Weise einen gut egali  sierenden, wasch- und     walkechten,        grünstichig     grauen Wollfarbstoff.  



  <I>Beispiel:</I>  Man löst 10 Gewichtsteile des     Anthri-          mids    aus     1-p-Anisidino-4-aminoarithrachinon     und     1-Brom-4-methoxy-anthrachinon    in       150        Gewichtsteilen        Oleum        von    3     bis    5     %        An-          hydridgehalt    und rührt bei 15 bis 200 un-         gefähr        1/2    Stunde.

   Man erhält einen gut  egalisierenden, wasch- und     walkechten,        grün-          stichiLy        Zrauen        Wollfarbstoff:  



  <B> Additional patent </B> to main patent no. 208545. Process for the production of an anthraquinone derivative. The subject of the present patent is a process for the production of a new wool dye of the anthraquinone series, which is characterized by

   that the anthrimide of 1-p-anisidino-4-amino-arrthraquinone and 1-halo-4-methoxyarrthraquinone is treated with oleum of 3 to 5% anhydride content at a temperature of 15 to 20 ° C. for about half an hour . In this way, a well-leveling, wash- and mill-fast, greenish gray wool dye is obtained.



  <I> Example: </I> 10 parts by weight of the anthrimide from 1-p-anisidino-4-aminoarithraquinone and 1-bromo-4-methoxy-anthraquinone are dissolved in 150 parts by weight of oleum with an anhydride content of 3 to 5% and stir at 15 to 200 for about 1/2 hour.

   The result is a well-leveling, wash- and mill-fast, green-tinted Zrauen wool dye:

PATENTANSPRUCH: Verfahren zur Herstellung eines Anthra- chinonderivates, dadurch gekennzeichnet, dass man das Anthrimid aus 1-p-Anisidino-4- amino-anthrachinon und 1-Halogen-4-methoxy- anthrachinon mit Oleum von 3 bis 5 % An- hydridgehalt bei einer Temperatur von 15 bis 201) C ungefähr eine halbe Stunde be handelt. PATENT CLAIM: Process for the production of an anthrachinone derivative, characterized in that the anthrimide is made from 1-p-anisidino-4-amino-anthraquinone and 1-halo-4-methoxy-anthraquinone with an oleum of 3 to 5% anhydride content a temperature of 15 to 201) C for about half an hour. Die erhaltene Sulfosäure stellt einen gut egalisierenden, wasch- und walkechten, grün stichig grauen Wollfarbstoff dar. The sulfonic acid obtained is a well-leveling, wash- and mill-fast, green-tinged gray wool dye.
