Description

  

  Verfahren zur Darstellung eines     Ogycarbonsäiuearylides.       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-Oxydiphenylamin-          carbonsäure    mit     1,

  5-Naphtylendiamin    in     Sus-          pensions-    oder Lösungsmitteln in Gegenwart  eines     Kondensationsmittels    erwärmt.  



       Das        erhaltene        Bis-   <B>.</B>     (3-oxydiphenylarnincar-          bonyl)-1,5-naphtylendiamiri    kristallisiert aus  Nitrobenzol in fast farblosen kleinen     Nädel-          chen    vom F. 293       (unkorr.).     



  Es soll als Zwischenprodukt zur Herstel  lung von     Farbstoffen    verwendet werden.       Beispiel:     ''2,9 Teile     3-Oxydiphenylamincarborisäure     und 7,9 Teile 1,5     -Naphtylendiamin    werden  in 300 Teile Chlorbenzol eingetragen, sodann  mit 6 Teilen     Phosphortrichlorid    allmählich  versetzt und die Temperatur dann noch  einige Stunden auf 110   gehalten.

   Man macht  nun mit     Sodalösung        aalkalisch,    bläst das    Chlorbenzol mit Dampf ab und reinigt das  gebildete     Bis-(3-oxydiplienylamincarbonyl)-          1,5-naphtylendiamiri        rionhnials    durch Lösen  in Lauge und Fällen mit Kohlensäure.



  Process for the preparation of an Ogycarbonsäiuearylides. The present patent relates to a process for the preparation of an oxyphenyl arylamine carboxylic acid arylide, characterized in that the 3-oxydiphenylamine carboxylic acid which can be prepared by carbonic acid pressure melt of the alkali salts of 3-oxydiphenylamine is 1,

  5-naphthylenediamine is heated in suspension or solvents in the presence of a condensing agent.



       The bis- <B>. </B> (3-oxydiphenylarnine carbonyl) -1,5-naphthylenediamine crystallized from nitrobenzene in almost colorless little needles of F. 293 (uncorrupted).



  It is intended to be used as an intermediate in the manufacture of dyes. Example: '' 2.9 parts of 3-oxydiphenylaminecarboric acid and 7.9 parts of 1,5-naphthylenediamine are introduced into 300 parts of chlorobenzene, then 6 parts of phosphorus trichloride are gradually added and the temperature is then held at 110 for a few hours.

   It is now alkaline with soda solution, the chlorobenzene is blown off with steam and the bis (3-oxydiplienylamine carbonyl) 1,5-naphthylenediamine rionhnials formed are purified by dissolving in alkali and precipitating with carbonic acid.
