Description

  

      Verfahren    zur Darstellung eines     Ogycarbonsänrearylides.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Darstellung eines     Oxyphenyl-          arylamincarbonsäurearylides,    dadurch gekenn  zeichnet,

   dass man die durch     Kohlensäure-          druckschmelze    der     Alkalisalze    von     3-Oxy-          diphenylamindarstellbare        3-Oxydiphenylamin-          carbonsäure    mit     i3-Naphtylamin    in     Suspen-          sions-    oder Lösungsmitteln in Gegenwart eines  Kondensationsmittels erwärmt.  



  Das erhaltene     3-Oxydiphenylamincarbon-          säur#e-p-riaphtalid    kristallisiert aus Chlorben  zol in farblosen Nadeln vom F. 208       (unkorr.).     



  Es soll als Zwischenprodukt zur Herstel  lung von Farbstoffen verwendet werden.  <I>Beispiel:</I>  22,9 Teile     3-Oxydipheriylamiricai-bonsäure     und 14,3 Teile     P-Naphtylamin    werden in  300 Teile     Xylol    eingetragen, sodann mit 6  Teilen     Phosphortrichlorid    allmählich versetzt  und die Temperatur dann noch einige Stun  den auf<B>110'</B> gehalten. Man macht nun mit       Sodalösung    alkalisch, bläst das     Xylol    mit    Dampf ab und reinigt das gebildete     3-Oxy-          diphenylamincarborisäure-ss-naphtalid    noch  mals durch Lösen in Lauge und Fällen     finit     Kohlensäure.



      Process for the preparation of an Ogycarbonsänrearylide. The present patent relates to a method for the preparation of an oxyphenyl arylamincarboxylic acid arylide, characterized in that

   that the 3-oxydiphenylamine carboxylic acid, which can be prepared by carbonic acid pressure melt of the alkali metal salts of 3-oxydiphenylamine, is heated with 13-naphthylamine in suspension or solvents in the presence of a condensing agent.



  The 3-oxydiphenylaminecarboxylic acid # e-p-riaphthalide obtained crystallizes from chlorobenzene in colorless needles of F. 208 (uncorr.).



  It is intended to be used as an intermediate in the manufacture of dyes. <I> Example: </I> 22.9 parts of 3-Oxydipheriylamiricai-bonsäure and 14.3 parts of P-naphthylamine are introduced into 300 parts of xylene, then 6 parts of phosphorus trichloride are gradually added and the temperature is then a few hours to < B> 110 '</B> held. It is now made alkaline with soda solution, the xylene is blown off with steam and the 3-oxydiphenylaminecarboric acid-ss-naphthalide formed is purified again by dissolving it in alkali and precipitating finite carbonic acid.
