  Zusatzpatent     zum    Hauptpatent     Nr.    274524.    Verfahren zur Darstellung eines lebhaften violetten     Walkfarbstoffes     der     Anthrachinonreihe.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines lebhaften  violetten     Walkfarbstoffes    der     Anthraehinon-          reihe,    das dadurch gekennzeichnet ist,     dass    man  <B>1 -</B>     Amino   <B>-</B> 2     -brom-    4<B>-</B>     (2'.4'.6'-trimethylphenyl-          amino)

  -anthrachinon    mit     4-tert.Amyl-l-oxy-          benzol    in Gegenwart eines säurebindenden  Mittels erhitzt und die entstandene     Farbstoff-          base        sulioniert.     



  <I>Beispiel:</I>  In<B>100 g</B> geschmolzenes     4-tert.Amyl-l-oxy-          ben7ol    giesst man eine Lösung- von<B>15</B> Teilen       Kaliumhydroxyd    in<B>15</B> Teilen Wasser und de  stilliert das Wasser ab, bis die Schmelze die  Temperatur von<B>1500 C</B> erreicht hat.

   Nun  trägt man<B>16,8</B> Teile     1-Aniino-2-broin-4-          (2'.4'.6'-        trimethylphenylamino)   <B>-</B>     antlirachinon     ein und rührt während<B>6</B> Stunden bei     15011   <B>C.</B>  Nach dem Abkühlen     auf   <B>1000 C</B> verdünnt man  mit<B>160</B> Teilen Alkohol,     lässt    auf Zimmertem  peratur erkalten und filtriert die auskristalli  sierte     Farbstoffbase    ab. Man     wäseht    mit Alko  hol, dann mit     heissemWasser    und trocknet.  



  <B>50</B> Teile der     Parbstoffbase    werden in<B>90</B>  Teile     Schwefelsäuremonohydrat    und<B>50</B> Teile       Oleum    von     281/o    Gehalt eingetragen,     wobeidie     Temperatur durch Kühlung unterhalb 400<B>C</B>  gehalten wird.

   Man rührt die Lösung während  einer halben Stunde bei 40 bis 450<B>C.</B> Eine    Probe in Wasser ist nun ohne     Rüekstaild        lös-          lieh.    Man     lässt    die Lösung in eine Mischung  von<B>700</B> Teilen Eis,<B>700</B> Teilen Eiswasser     und     140 Teilen Kochsalz laufen, filtriert den aus  geschiedenen Farbstoff und     presst    ihn von der  anhaltenden Mutterlauge gut ab. Der Farb  stoff wird mit wenig Wasser zu einem dicken  Brei angerührt und durch allmähliche Zugabe  von trockener Soda neutral gestellt. Nach dem  Trocknen erhält man ein dunkelviolettes Pul  ver, das sieh in Wasser mit lebhaft violetter  Farbe löst.

   Der Farbstoff zieht aus schwach  saurem Bade auf Wolle in lebhaften     Violett-          tönen    von ausgezeichneter     Walk-    und Licht  echtheit.



  Additional patent to the main patent No. 274524. Process for the preparation of a lively violet fulled milled dye of the anthraquinone series. The subject of the present patent is a process for the production of a lively violet milled dye of the anthraehinone series, which is characterized in that <B> 1 - </B> Amino <B> - </B> 2 -bromo-4 <B > - </B> (2'.4'.6'-trimethylphenyl-amino)

  -anthraquinone is heated with 4-tert-amyl-l-oxybenzene in the presence of an acid-binding agent and the resulting dye base is sulionized.



  <I> Example: </I> A solution of <B> 15 </B> parts of potassium hydroxide in <B> 100 g </B> of melted 4-tert-amyl-l-oxyben7ol is poured > 15 </B> parts of water and distilled the water until the melt has reached a temperature of <B> 1500 C </B>.

   Now you enter <B> 16.8 </B> parts of 1-aniino-2-broin-4- (2'.4'.6'-trimethylphenylamino) <B> - </B> antlirachinon and stir during < B> 6 </B> hours at 15011 <B> C. </B> After cooling to <B> 1000 C </B>, dilute with <B> 160 </B> parts of alcohol and leave at room temperature cool and filter off the crystallized dye base. You wash with alcohol, then with hot water and dry.



  <B> 50 </B> parts of the paraffin base are added to <B> 90 </B> parts of sulfuric acid monohydrate and <B> 50 </B> parts of oleum with a content of 281 / o, the temperature being below 400 by cooling C is held.

   The solution is stirred for half an hour at 40 to 450 ° C. A sample is now soluble in water without rüekstaild. The solution is allowed to run into a mixture of 700 parts of ice, 700 parts of ice water and 140 parts of common salt, the separated dye is filtered off and it is well pressed off from the persistent mother liquor. The dye is mixed with a little water to a thick paste and made neutral by gradually adding dry soda. After drying, a dark purple powder is obtained which dissolves in water with a vivid purple color.

   The dye pulls from a weakly acidic bath onto wool in lively purple tones with excellent fullness and lightfastness.
