Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>218368.</B>    Verfahren zur Herstellung eines     stielistoffhaltigen        liondensationsproduktes.       Es wurde gefunden,     dass    ein stickstoffhal  tiges Kondensationsprodukt hergestellt werden  kann, wenn man auf     (5'-Benzoylamino-l'-          anthrachinonyl   <B>-)</B>     (4'-        benzoylamino   <B>- l'-</B>     anthra        -          chinonyl-)        2,8-diaminochrysen    kondensierende  Mittel einwirken     lässt.     



  Das stickstoffhaltige Kondensationsprodukt  färbt Baumwolle aus gelbroter     Küpe    in braunen,  sehr echten Tönen.  



  Die Einwirkung kondensierender Mittel, die  oxydierend wirken können, wie z. B.     Alumi-          niumehlorid,    gegebenenfalls in Gegenwart or  ganischer Säurechloride und von Verdünnungs  oder Lösungsmitteln, kann bei höherer oder  niederer Temperatur erfolgen. Als Kondensa  tionsmittel besonders geeignet sind Schwefel  säure und ihre Derivate, die zweckmässig bei  niederer Temperatur angewandt werden. Sehr  wahrscheinlich werden bei der Einwirkung  kondensierender Mittel     Karbazolringe    gebildet.  



  Das neue stickstoffhaltige Kondensations  produkt kann durch ein- oder mehrmaliges         Kristallisieren    aus     organisehen    Lösungsmitteln  oder durch Behandlung mit oxydierenden Mit  teln, wie z. B.     Alkalinitritlösung    in saurem  Medium,     Alkalihypochloritlösung    oder     Perbo-          ratlösung,    gereinigt werden.  



  <I>Beispiel:</I>  2 Teile     (5'.Benzoylamino.1'.aiithrachinonyl.)          (4'-        benzoylamino   <B>-l'-</B>     a-nthrachinonyl   <B>-) 2,8 -</B>     di        -          aminochrysen    werden in<B>36</B> Teile     93/oige     Schwefelsäure eingetragen und<B>16</B> Stunden bei  <B>15 -</B> 22<B>1</B> verrührt. Zar Beendigung der     Farb-          stoffbildung    wird in Eis, versetzt mit etwas       Natriumnitrit,    eingetragen und<B>1</B>     '/2    Stunde  kräftig gerührt.

   Hierauf wird filtriert, aus  gewaschen und der Farbstoff     verpastet.  



  Additional patent to main patent no. <B> 218368. </B> Process for the production of a liondensation product containing chemical substances. It has been found that a nitrogen-containing condensation product can be produced if (5'-benzoylamino-l'-anthraquinonyl <B> -) </B> (4'-benzoylamino <B> - l '- </ B > anthra - quinonyl-) 2,8-diaminochrysen condensing agent.



  The nitrogen-containing condensation product dyes cotton from a yellow-red vat in brown, very real shades.



  The action of condensing agents that can have an oxidizing effect, such as. B. aluminum chloride, optionally in the presence of organic acid chlorides and diluents or solvents, can be carried out at a higher or lower temperature. Sulfuric acid and its derivatives, which are expediently used at low temperature, are particularly suitable as condensation agents. Carbazole rings are very likely to be formed on exposure to condensing agents.



  The new nitrogen-containing condensation product can be obtained by single or multiple crystallization from organic solvents or by treatment with oxidizing means, such as. B. Alkali nitrite solution in acidic medium, alkali hypochlorite solution or perborate solution, can be cleaned.



  <I> Example: </I> 2 parts (5'.Benzoylamino.1'.aiithraquinonyl.) (4'-benzoylamino <B> -l'- </B> a-nthraquinonyl <B> -) 2.8 - </B> di - aminochryses are entered in <B> 36 </B> parts of 93% sulfuric acid and <B> 16 </B> hours at <B> 15 - </B> 22 <B> 1 < / B> stirred. When the dye formation is complete, it is added to ice, mixed with a little sodium nitrite, and vigorously stirred for 1½ hours.

   It is then filtered, washed out and the dye made into a paste.
