Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 218368.    Verfahren zur Herstellung eines     stielistoffhaltigen    Kondensationsproduktes.    Es wurde gefunden, dass ein stickstoff  haltiges Kondensationsprodukt hergestellt wer  den kann, wenn man auf     1'-(Anthrachirionyl-)          2-aminochrysen    kondensierende Mittel ein  wirken lässt.  



  Das erhaltene stickstoffhaltige Kondensa  tionsprodukt stellt ein gelbes Pulver dar, das  sich in konzentrierter Schwefelsäure mit oliver  Farbe löst, wasserlöslich ist und Wolle aus  saurem Bade in kräftigen, reinen und echten       Orangetönen    färbt.  



  Die Einwirkung kondensierender Mittel,  die oxydierend wirken können, wie z. B.  Aluminiumchlorid, gegebenenfalls in Gegen  wart organischer Säurechloride und von     Ver-          dünnungs-    oder Lösungsmitteln, kann bei  höherer oder niederer Temperatur erfolgen.  Als Kondensationsmittel besonders geeignet  sind Schwefelsäure und     ihre    Derivate, die  zweckmässig bei niederer Temperatur ange  wandt werden. Sehr wahrscheinlich werden  bei der Einwirkung kondensierender Mittel       Karbazolringe    gebildet.

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

           Beispiel:     1,5 Teile     1'-(Anthrachinonyl-)2-amino-          chrysen    werden in 27 Teile konzentrierte  Schwefelsäure     eingetragen    und 16 Stunden  bei einer Temperatur von. 20-30   gerührt.  Nun wird in Eis eingetragen und abgesaugt,  der gelbe Niederschlag unter Erwärmen in  verdünnter Natronlauge gelöst, von Verun  reinigungen filtriert- und m_     it        Kochsalz    der  Farbstoff gefällt.  



  Zu dem gleichen Farbstoff gelangt man,  wenn das Kondensationsprodukt mit konzen  trierter Schwefelsäure bei 50-60  verrührt  wird.



  <B> Additional patent </B> to main patent no. 218368. Process for the production of a condensation product containing chemical substances. It has been found that a nitrogen-containing condensation product can be produced if 1 '- (anthraquirionyl) 2-aminochrysenic condensing agents are allowed to act.



  The nitrogenous condensation product obtained is a yellow powder that dissolves in concentrated sulfuric acid with an olive color, is water-soluble and dyes wool from an acid bath in strong, pure and genuine orange tones.



  The action of condensing agents that can have an oxidizing effect, such as. B. aluminum chloride, possibly in the presence of organic acid chlorides and diluents or solvents, can take place at higher or lower temperatures. Sulfuric acid and its derivatives, which are expediently applied at low temperature, are particularly suitable as condensing agents. Carbazole rings are very likely to be formed upon exposure to condensing agents.

      The new nitrogen-containing condensation product can be crystallized one or more times from organic solvents or by treatment with oxidizing agents, such as. B. Alkali nitrite solution in an acidic medium, alkali hypochlorite solution or perborate solution can be cleaned.

           Example: 1.5 parts of 1 '- (anthraquinonyl-) 2-aminochrysenic are added to 27 parts of concentrated sulfuric acid and stored for 16 hours at a temperature of. Stirred 20-30. It is then poured into ice and filtered off with suction, the yellow precipitate is dissolved in dilute sodium hydroxide solution with heating, impurities are filtered off and the dye is precipitated with common salt.



  The same dye is obtained if the condensation product is stirred with concentrated sulfuric acid at 50-60.
