Description

  

  Verfahren zur Herstellung eines neuen Kondensationsproduktes.         Die        vorliecende    Erfindung betrifft ein  <B>M</B>  Verfahren zur Herstellung eines neuen     Kon-          clensationsproduktes    und ist dadurch     gekenn-          zeielniet,        dass    man das nach dem Verfahren  der     Patentsehrift        Nr.   <B>251646</B> erhältliche     bro-          mierte        Naphtliochinonimid    mit Anilin kon  densiert.  



  <I>Beispiel:</I>  <B><I>10</I> g</B>     bromiertes        Naplitlioehiiionimicl        (er-          lialten        naeli    dein Beispiel der Patentschrift.       Nr.   <B>251646)</B> werden mit<B>100 g</B> Anilin und  <B>0,5 g</B> Borsäure unter gutem Rühren während  24 Stunden auf<B>50</B> bis<B>600</B> erwärmt.

   Der An  satz wird nun in     übersehüssige        109,lige    Salz  säure gegossen und der Niederschlag     abfil-          triert,    neutral gewaschen und     getroeknet.     Man erhält eine harzartige, brüchige Masse,  die sieh leicht pulverisieren     lässt    und in<B>Al-</B>         kohol    mit blauvioletter und in     ELSO,    mit       rötiiehvioletter    Farbe     löslieh    ist. Die neue  Verbindung soll als Farbstoff für     Aeetatseide          erwendet    werden.



  Process for the production of a new condensation product. The present invention relates to a <B> M </B> process for the production of a new condensation product and is characterized by the fact that the brominated one obtainable according to the process of patent document no. 251646 </B> is used Naphthioquinonimide condensed with aniline.



  <I> Example: </I> <B> <I> 10 </I> g </B> brominated Naplitlioehiiionimicl (naeli your example achieved the patent. No. <B> 251646) </B> are with <B> 100 g </B> aniline and <B> 0.5 g </B> boric acid heated to <B> 50 </B> to <B> 600 </B> for 24 hours with thorough stirring.

   The batch is then poured into excess 10% hydrochloric acid and the precipitate is filtered off, washed neutral and dried. A resin-like, brittle mass is obtained, which can be easily pulverized and is soluble in <B> Al </B> alcohol with a blue-violet color and in ELSO with a reddish-violet color. The new compound will be used as a dye for acetate silk.
