  Zusatzpatent zum Hauptpatent     Nr.   <B>219656.</B>    Verfahren zur Herstellung eines sauren     Wollfarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines sauren       Wollfarbstoffes,    dadurch gekennzeichnet,     dass     man     1-Amino-4-bromanthrachinon-2-sulfon-          säure    mit     4-Aminobenzyl-piperidin    konden  siert und das erhaltene Kondensationsprodukt  mit einem sulfonierenden Mittel bis zum Ein  tritt einer     Sulfogruppe    behandelt.  



  Der so erhaltene Farbstoff löst sieh in  konzentrierter Schwefelsäure mit schmutzig  blauvioletter Farbe, die auf Zusatz von     Para-          formaldehyd    nach     gelbstic'hig    grün     um-          .schlägt,    und färbt Wolle in     rot-stichig    blauen  Tönen von guter Lichtechtheit.

   Er besitzt ein  hervorragendes     Egalisierungsvermögen.       <I>Beispiel:</I>    <B>33</B> Teile     1-Amino-4-bromanthrachinon-2-          sulfonsäure    werden in einem Gemisch aus  etwa<B>1700</B> Teilen Wasser und<B>600</B> Teilen<B>Al-</B>  kohol gelöst und mit 24 Teilen     4-Amino-          benzyl-piperi,din,   <B>33</B> Teilen Natriumbiearbo-         nat    und<B>3,3</B> Teilen     Kupferelilorür    versetzt.  Die Lösung wird mehrere Stunden zum  Sieden erhitzt und das gebildete Kondensa  tionsprodukt     durcli        Aussäuern    abgeschieden.

    Es wird abgesaugt und mit heissem Wasser  gut     ausgewasclien.     



  <B>30</B>     Teile,des    obigen     Kondensationsproduk-          teas    werden in einem Gemisch aus<B>150</B> Teilen       Schwefelsäure-Monehydrat    und<B>30</B> Teilen       ffligem        Oleum    gelöst. Die Reaktionsmasse  wird ungefähr 20 Stunden auf 40-45'<B>C</B>  erwärmt und dann mit Eis versetzt. Die stark  mineralsaure     Farbsto-fflösung    wird nun mit  Natronlauge von     33'Bö    neutralisiert und     der     gebildete Farbstoff durch Zufügen von Koch  salz abgeschieden. Er wird abgesaugt und  mit Salzwasser von     15'B6        uachgewaseIien.  



  Additional patent to main patent no. <B> 219656. </B> Process for the production of an acidic wool dye. The present patent relates to a process for the preparation of an acidic wool dye, characterized in that 1-amino-4-bromoanthraquinone-2-sulfonic acid is condensed with 4-aminobenzyl-piperidine and the condensation product obtained is condensed with a sulfonating agent occurs a sulfo group treated.



  The dye obtained in this way dissolves in concentrated sulfuric acid with a dirty blue-violet color, which changes to yellowish green on addition of paraformaldehyde, and dyes wool in reddish-tinged blue shades of good lightfastness.

   He has an excellent leveling ability. <I> Example: </I> <B> 33 </B> parts of 1-amino-4-bromoanthraquinone-2-sulfonic acid are in a mixture of about <B> 1700 </B> parts of water and <B> 600 </B> Parts of <B> Al- </B> alcohol dissolved and mixed with 24 parts of 4-aminobenzyl-piperi, din, <B> 33 </B> parts of sodium carbonate and <B> 3.3 < / B> Parts of copper lilac staggered. The solution is heated to boiling for several hours and the condensation product formed is deposited by acidification.

    It is suctioned off and washed out well with hot water.



  <B> 30 </B> parts of the above condensation product are dissolved in a mixture of <B> 150 </B> parts of sulfuric acid monhydrate and <B> 30 </B> parts of liquid oleum. The reaction mass is heated to 40-45 ° C for about 20 hours and then ice is added. The strongly mineral acid dye solution is then neutralized with sodium hydroxide solution of 33 'Bö and the dye formed is separated off by adding sodium chloride. It is sucked off and washed with salt water of 15'B6.
