Description

  

  Verfahren zur Darstellung eines     Oxyearbonsäure.trylides.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Darstellung eines     Oxyphenyl-          allyiamiiicai-botisätireaj,ylides,    dadurch gekenn  zeichnet,     dass    war)

   die durch     Kohlensäure-          druckschmelze    der     Alkalisalze    von     3-Oxy-4'-          chlordiphenylamin    darstellbare<B>3<I>-</I></B>     Oxy   <B><I>-</I></B>     4'-          chloi-diphetiylarninearboiisätire    mit     o-Anisidin     in     Suspensions-    oder Lösungsmitteln in Ge  genwart eines Kondensationsmittels     ei-wärmt.     



  Das erhaltene     S-Oxy-4'-chlordipheiiyiamiii-          earbonsäure-o-aiiisidid    ist ein braunes Pulver,  das nach dem     UmkrIstallisieren    aus Chlor  benzol den Schmelzpunkt 142'<B>C</B> zeigt.  



  Es soll als     Zwischenprodukt    zur Herstel  lung von Farbstoffen verwendet werden.  <I>Beispiel:</I>  <B>52,7</B> Teile     3-Oxy-4'-chlordiphenylamincar-          bonsäure    werden mit 24,6 Teilen     o-Anisidin     in<B>700</B> Teilen     Dirnethylanilin    bei<B>60-700</B>  gelöst, 12 Teile     Phosphortrichlorid    bei dieser    Temperatur zugesetzt Lind<B>8-10</B> Stunden  auf 1200 gehalten.

   Das Reaktionsprodukt  wird in Überschüssige verdünnte Salzsäure  eingerührt, der Niederschlag gewaschen und  nach     Alkalischmacheii        mit        Sodalösung    etwa  Doch vorhandenes     Dimeühylaniliii    durch     Was-          serdampfdestillation    entfernt. Das zurückblei       beiide3-Oxy-4'-chlordipbeiiylaininearbongäut-e-          o-anisidid    wird zwecks Reinigung in Natron  lauge gelöst, filtriert und     mit    Kohlensäure  gefällt.



  Process for the preparation of an Oxyearbonsäure.trylides. The present patent relates to a method for the preparation of an Oxyphenyl- allyiamiiicai-botisätireaj, ylides, characterized in that was)

   the <B> 3 <I> - </I> </B> Oxy <B><I>-</I> </B> 4 which can be prepared by carbonic acid pressure melt of the alkali salts of 3-oxy-4'-chlorodiphenylamine '- chloi-diphetiylarninearboiisätire with o-anisidine in suspending or solvents in the presence of a condensing agent.



  The S-oxy-4'-chlorodipheiiyiamiii-carboxylic acid-o-alisidide obtained is a brown powder which, after recrystallization from chlorobenzene, has a melting point of 142 ° C.



  It is intended to be used as an intermediate in the manufacture of dyes. <I> Example: </I> <B> 52.7 </B> parts of 3-oxy-4'-chlorodiphenylaminecarboxylic acid are combined with 24.6 parts of o-anisidine in 700 parts of dirnethylaniline dissolved at <B> 60-700 </B>, 12 parts of phosphorus trichloride added at this temperature and held at 1200 for 8-10 hours.

   The reaction product is stirred into excess dilute hydrochloric acid, the precipitate is washed and, after making alkaline with soda solution, any dimethyl anilium present is removed by steam distillation. The remaining lead 3-oxy-4'-chlorodipbeiiylaininearbongäut-e- o-anisidid is dissolved in caustic soda for cleaning purposes, filtered and precipitated with carbonic acid.
