Description

  

  Verfahren zur Darstellung eines     Oxyearbonsäitrearylide#,.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Darstellung eines     Oxyphenyl-          ai-ylamitiearboiisät.ireaz,ylides,    dadurch gekenn  zeichnet,

       dass    man die durch     Kohlensäure-          druckschmelze    der     Alkalisalze    von     3-Oxy-          diplienylamin    darstellbare     8-Oxydiphenylamin-          carbonsäure    mit     Dianisidin    in     Suspensions-          oder    Lösungsmitteln in Gegenwart eines  Kondensationsmittels erwärmt,  Das erhaltene     Bis-(3-oxydiphenylamin-          carbonyl)

  -dianisidin    bildet nach dem     Um-          kristallisiereii    aus     o-Dichlorbetizol    ein rötlich  gefärbtes amorphes Pulver vom F. über 340       (unkorr.).     



  Es soll als Zwischenprodukt zur Herstel  lung von Farbstoffen verwendet werden.  <I>Beispiel:</I>  <B>22,9</B> Teile     3-Oxydiphetiylaiiiiiiearbonsäure     und 12,2 Teile     Dianisidin    werden in<B>300</B>  Teile Chlorbenzol eingetragen, sodann mit  <B>6</B> Teilen     Phosphortrichlorid    allmählich ver  setzt und die Temperatur dann noch einige  Stunden auf<B>100'</B> gehalten.

       Alan    macht nun  mit     Sodalösung    alkalisch, bläst das Chlor-         benzol    mit Dampf ab und reinigt das gebil  dete     Bis-(3-oxydipheiiylatiiiiie#,irbonyl)-dianisi-          din    nochmals durch Lösen in Lauge     und     Fällen mit Kohlensäure.



  Process for the preparation of an oxyearboxylic acid arylide # ,. The present patent relates to a process for the preparation of an oxyphenyl-ai-ylamitiearboiisät.ireaz, ylides, characterized in that

       that the 8-oxydiphenylamine carboxylic acid, which can be prepared by carbonic acid pressure melt of the alkali salts of 3-oxydiphenylamine, is heated with dianisidine in suspending agents or solvents in the presence of a condensing agent.

  After recrystallization from o-dichlorobetizole, -dianisidine forms a reddish-colored amorphous powder with a F. over 340 (uncorrupted).



  It is intended to be used as an intermediate in the manufacture of dyes. <I> Example: </I> <B> 22.9 </B> parts of 3-oxydiphetiylaiiiiiiarboxylic acid and 12.2 parts of dianisidine are added to <B> 300 </B> parts of chlorobenzene, then with <B> 6 < / B> Parts of phosphorus trichloride are gradually added and the temperature is then kept at <B> 100 '</B> for a few hours.

       Alan now makes alkaline with a soda solution, blows off the chlorobenzene with steam and cleans the bis (3-oxydipheiiylatiiiiie #, irbonyl) dianisidine again by dissolving it in lye and precipitating it with carbonic acid.
