Description

  

  <B>Verfahren zur Herstellung eines neuen Kondensationsproduktes.</B>    Die vorliegende Erfindung betrifft. ein  Verfahren zur     Herstellung    eines neuen Kon  densationsproduktes und ist dadurch gekenn  zeichnet, dass man das nach dem Verfahren  der Patentschrift Nr. 260232 erhältliche chlo  rierte     Naphthochinonimid    mit Anilin konden  siert.  



  <I>Beispiel:</I>  5 g des nach dem Beispiel der Patent  schrift Nr. 260232 erhältlichen chlorierten       Naphthoehinonimids    werden mit 20 g Anilin,  200 cm' Äthanol und 0,5 g Borsäure während  16 Stunden zum Sieden erhitzt. Nach dem       Abdestillieren    des Äthanols wird der Rück  stand in Wasser ausgeladen, mit     Salzsäure    an  gesäuert, filtriert. und neutral gewaschen.       plan    erhält ein dunkles Pulver, das in Ätha-         nol    mit. graublauer und in     H,S04    mit violet  ter Farbe löslich ist. Das neue Produkt soll  als Farbstoff für     Acetatseide        Verwendung     finden.



  <B> Process for the preparation of a new condensation product. </B> The present invention relates to. a process for the production of a new condensation product and is characterized in that the chlorinated naphthoquinonimide obtainable by the process of patent specification No. 260232 is condensed with aniline.



  <I> Example: </I> 5 g of the chlorinated naphthoehinonimide obtainable according to the example of patent specification No. 260232 are heated to boiling with 20 g of aniline, 200 cm 'of ethanol and 0.5 g of boric acid for 16 hours. After distilling off the ethanol, the residue is unloaded into water, acidified with hydrochloric acid, filtered. and washed neutral. plan receives a dark powder that is mixed in with ethanol. is gray-blue and soluble in H, S04 with a violet color. The new product will be used as a dye for acetate silk.
