Description

  

  Verfahren zur Darstellung     eines        Oxycarbonsäurearylides.       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-          diphenylamin    darstellbare 3 -     Oxydiphenyl-          ainincarbonsäure    mit einem chlorierenden  Mittel behandelt und das entstandene     3-Oxy-          diphenylamiricar        bonsäui-echlorid    mit     o-Toluidin     in     Suspensions-    oder Lösungsmitteln erwärmt.  



  Das erhaltene     3-Oxydiphenylamincarboii-          säure-o-toluidid        kristallisiert    aus     Eisessig    in  Blättchen und besitzt den Schmelzpunkt 185  .  



  Es soll als Zwischenprodukt zur Herstel  lung von     Farbstoffen    verwendet werden.       Beispiel:          'l6,3    Teile     3-Oxydiphenylamincarbonsäure     und 120 Teile     Thionylchlorid    werden in 1000  Teile     Ligroin    eingetragen und bis zur Lösung    der     Carbonsäure    zum Sieden erhitzt.

   Das     Li-          groin    und überschüssige     Thionylchlorid    wird  dann im Vakuum     abdestilliert,    der     Rückstand     mit 750 Teilen     Toluol    und<B>35,7</B> Teilen     o-To-          luidin    versetzt     -und    bis zur     Beendigung    der       Salzsäuregasentwicklung    im Sieden gehalten.

    Das Reaktionsgemisch wird nun mit Soda  lösung bis zur     Alkalität    versetzt, das     Toluol     durch Blasen mit Wasserdampf entfernt und  das gebildete     o-Toluidid    durch     Lmlösen    aus  Lauge und Fällen mit     Kohlensäure    gereinigt.



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

   that one treats the 3-oxydiphenylamine carboxylic acid, which can be prepared by carbonic acid pressure melt of the alkali salts of 3-oxydiphenylamine, with a chlorinating agent and the resulting 3-oxydiphenylamiricarboxylic acid chloride is heated with o-toluidine in suspension or solvents.



  The 3-oxydiphenylaminecarboiic acid-o-toluidide obtained crystallizes from glacial acetic acid in flakes and has a melting point of 185.



  It is intended to be used as an intermediate in the manufacture of dyes. Example: 16.3 parts of 3-oxydiphenylamine carboxylic acid and 120 parts of thionyl chloride are introduced into 1000 parts of ligroin and heated to the boil until the carboxylic acid has dissolved.

   The liquor and excess thionyl chloride are then distilled off in vacuo, 750 parts of toluene and 35.7 parts of o-toluidine are added to the residue and the mixture is kept boiling until the evolution of hydrochloric acid gas has ended.

    Soda solution is then added to the reaction mixture until it is alkaline, the toluene is removed by blowing with steam and the o-toluidide formed is purified by dissolving it from lye and precipitating with carbonic acid.
