Description

  

  Verfahren     zur    Darstellung eines     Oxyearbonsänrearylides.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Darstellung eines     Oxypbenyl-          arylaniincarbonsäurearylides,    dadurch gekenn  zeichnet,

   dass man die durch     Kohlensäure-          druckschmelze    der     Alkalisalze    von 3 -     Oxy-          diplienylamin    darstellbare 3 -     Oxydiphenyl-          aininoarbonsäure    mit     p-Nitroanilin    in     Suspen-          sions-    oder Lösungsmitteln in Gegenwart  eures     Kondensationsmittels    erwärmt.  



  Das erhaltene     3-Oxydiplienylamincai-bon-          säure-p-nitroanilid    kristallisiert aus Eisessig  in gelbgrünen Nadeln vom F. 211-212         (unkorr.).     



  Es soll als Zwischenprodukt zur Herstel  lung von     Farbstoffen    verwendet werden.  <I>Beispiel:</I>  78 Teile 3 -     oxydiphenylamincarbonsaures     Natrium und 46 Teile     p-Nitroanilin    werden  in 750 Teile     Xylol    eingetragen, sodann mit  20 Teilen     Phosphortrichlorid    allmählich ver  setzt und die Temperatur dann noch einige       Stunden    auf     11W1    gehalten.

   Man macht nun    mit     Sodalösung    alkalisch, bläst das     Xylol     mit Dampf ab und reinigt das gebildete     3-Oxy-          diphenylamiricai-bonsäure-p-nitroanilid    noch  mals durch Lösen in Lange und Fällen mit  Kohlensäure.



  Process for the preparation of an oxyearboxylic acid acrylide. The present patent relates to a process for the preparation of an oxypbenyl arylaniincarboxylic acid arylide, characterized in that

   that the 3-oxydiphenyl-aininoarboxylic acid, which can be prepared by carbonic acid pressure melt of the alkali salts of 3-oxydiplienylamine, is heated with p-nitroaniline in suspension or solvents in the presence of your condensing agent.



  The 3-oxydiplienylamincai-bonsäure-p-nitroanilide obtained crystallizes from glacial acetic acid in yellow-green needles of F. 211-212 (uncorrupted).



  It is intended to be used as an intermediate in the manufacture of dyes. <I> Example: </I> 78 parts of sodium 3-oxydiphenylamine carboxylic acid and 46 parts of p-nitroaniline are introduced into 750 parts of xylene, then gradually added with 20 parts of phosphorus trichloride and the temperature is then held at 11W1 for a few hours.

   It is now made alkaline with soda solution, the xylene is blown off with steam and the 3-oxydiphenylamiricai-bonsäure-p-nitroanilide is purified again by dissolving in a long time and precipitating with carbonic acid.
