Description

  

      Verfahren    zur Herstellung eines     nenen        Zwischenproduktes    der     Teerfarbenindustrie.       Es wurde gefunden, dass man ein neues  Zwischenprodukt der Teerfarbenindustrie, das       2,4-Di-4'-oxy        naphthyl-        6-m-xylyl-1,3,5-triaziri     erhält, wenn man auf 1     Mol.        Cyanurchlorid     2     Mol.        a-Naphthol    und hierauf     m-Xylol,    ge  gebenenfalls in Gegenwart von     Kondensations-          und    Verdünnungsmitteln, einwirken lädt.

   Das       2,4-Di-4'-oxyriaphtliyl-6-m-xylyl-1,3,o'-triazin     bildet ein rotbraunes Pulver, welches sich in  Natronlauge mit gelber und in konzentrierter  Schwefelsäure mit rotvioletter Farbe löst.       Beispiel     In 1500 Teile     Schwefelkohlenstoff    werden  93 Teile     Cyanurchlorid    und 93 Teile Alumi  niumchlorid eingetragen. Nach 5 Minuten  werden 144 Teile     ä-Naphthol    in kleinen  Portionen zugesetzt, worauf 10-12 Stunden  gerührt wird.

   Das     Reaktionsprodukt    wird  vom Verdünnungsmittel getrennt und im  gleichen Gefäss mit 1500 Teilen     m-Xylol     und 50 Teilen Aluminiumchlorid bei einer  nahe dem Siedepunkt des     Xylols    liegenden  Temperatur während 8 Stunden behandelt.  Das neue Produkt, das höchstwahrscheinlich  das 2,4-Di-4'-oxynaphthyl-6-m-xylyl-1,3,5-tria-         zin    darstellt, wird durch wiederholtes Lösen  in Lauge und Ausfällen mit Säuren gereinigt.



      Process for the production of an intermediate product in the tar color industry It has been found that a new intermediate product of the tar color industry, the 2,4-di-4'-oxy naphthyl-6-m-xylyl-1,3,5-triaziri, is obtained if 2 moles of cyanuric chloride are added to 1 mole. α-Naphthol and then m-xylene, if necessary in the presence of condensation and diluents, act loads.

   The 2,4-di-4'-oxyriaphthyl-6-m-xylyl-1,3, o'-triazine forms a red-brown powder, which dissolves in sodium hydroxide solution with yellow and in concentrated sulfuric acid with red-violet color. Example 93 parts of cyanuric chloride and 93 parts of aluminum chloride are introduced into 1500 parts of carbon disulfide. After 5 minutes, 144 parts of α-naphthol are added in small portions, followed by stirring for 10-12 hours.

   The reaction product is separated from the diluent and treated in the same vessel with 1500 parts of m-xylene and 50 parts of aluminum chloride at a temperature close to the boiling point of xylene for 8 hours. The new product, which is most likely 2,4-di-4'-oxynaphthyl-6-m-xylyl-1,3,5-triazine, is purified by repeated dissolving in alkali and precipitation with acids.
