Description

  

  Verfahren zur Herstellung eines neuen Kondensationsproduktes.    Die vorliegende Erfindung betrifft ein  Verfahren zur Herstellung eines neuen Kon  densationsproduktes und ist dadurch gekenn  zeichnet, dass man das nach dem Verfahren  der     Patentsehrift        Nr.251646        erhältliehe        bro-          niierte        Nalilithocliinonimid    mit Phenol kon  densiert.  



  <I>Beispiel:</I>  17,3 g des nach dem Beispiel der Patent  schrift Nr. 251646 erhältlichen     bromierten          Naphthochinonimids    werden in 200     ein:'    Ätha  nol aufgeschwemmt und nach Zusatz von  23,8 g Phenol, 0,5     g        Borsäure    und 5 g     Na-          t.riuniacetat    während 18 Stunden zum Sieden  erhitzt. Nach dieser Zeit, destilliert man den  Alkohol ab, trägt das     Kondensationsprodukt     in Wasser ein, versetzt mit     Natriumhydroxy        d     bis zur     phenolphthaleinalkalischen    Reaktion,  filtriert und wäscht gut nach.

   Man erhält  ein dunkles Pulver, (las in     Äthanol    mit korn-         blumenblauer    und in     1-1-SO    4 mit     gelboliver     Farbe löslich ist und pflanzliche Fasern aus  einem     Natriumsulfid-Bade    in einem tiefen  Marineblau färbt.. Die Verbindung eignet     siele     zum Färben von     Aeetatseide.  



  Process for the production of a new condensation product. The present invention relates to a process for the production of a new condensation product and is characterized in that the bronzed nalilithocliinonimide obtained according to the process of patent application No. 251646 is condensed with phenol.



  <I> Example: </I> 17.3 g of the brominated naphthoquinonimide obtainable according to the example of patent specification no. 251646 are suspended in an: Ethanol and after adding 23.8 g of phenol, 0.5 g of boric acid and 5 g Na- t.riuniacetat heated to boiling for 18 hours. After this time, the alcohol is distilled off, the condensation product is introduced into water, sodium hydroxide is added until the phenolphthalein-alkaline reaction occurs, and the mixture is filtered and washed thoroughly.

   A dark powder is obtained which is soluble in ethanol with cornflower blue and in 1-1-SO 4 with yellow-olive color and dyes vegetable fibers from a sodium sulfide bath in a deep navy blue. The compound is suitable for dyeing acetate silk .
