Description

  

  Verfahren zur Herstellung eines     o-Aminodiaryläthers.       -Vorliegende Erfindung bezieht sieh auf  ein Verfahren zur Darstellung eines     o-          Aminodiaryläthers,    dadurch gekennzeichnet,       dass    man ein     Alkalisalz    von     P-Naphtol    auf       4-Diiiitro-l-chlorbenzol    einwirken     lUt     und den erhaltenen     5-Chlor-2--nitrophenyl-ss-          naphthyläther    reduziert.  



  Der so erhaltene     5-Chlor-2-aminophenyl-          ss-na.phthyläther        lässt    sich aus     Ligroin        um-          kristallisieren    und schmilzt bei<B>108</B> bis<B>109</B>  <I>Beispiel:</I>  Man mischt eine Lösung von 84 Teilen       fl-Kaphthylna.trium    in Spiritus mit einer  alkoholischen Lösung von<B>81</B> Teilen<B>3.</B>     4-          1)initro-l-chlorbenzol    und erwärmt einige  Zeit auf dem Wasserbad.

   Man erhält so  den     5-Chlor-2-nitrophenyl-ss-naphthyläther       vom Schmelzpunkt<B>109</B> bis<B>110 '</B> (aus ver  dünntem     Aceton).    Die Reduktion ergibt dann       5-Chlor-2-amiliophenyl-fl-naphthyläther.  



  Process for the preparation of an o-aminodiaryl ether. The present invention relates to a process for the preparation of an o-aminodiaryl ether, characterized in that an alkali salt of P-naphthol is allowed to act on 4-di-nitro-1-chlorobenzene and the 5-chloro-2-nitrophenyl-ss- naphthyl ether reduced.



  The 5-chloro-2-aminophenyl-ss-na.phthylether obtained in this way can be recrystallized from ligroin and melts at <B> 108 </B> to <B> 109 </B> <I> Example: </ I> Mix a solution of 84 parts of fl-Kaphthylna.trium in spirit with an alcoholic solution of <B> 81 </B> parts <B> 3. </B> 4- 1) initro-l-chlorobenzene and heat some time on the water bath.

   The 5-chloro-2-nitrophenyl-s-naphthyl ether with a melting point of <B> 109 </B> to <B> 110 '(from dilute acetone) is obtained in this way. The reduction then gives 5-chloro-2-amiliophenyl-fl-naphthyl ether.

PATENTANSPRUCH: Verfahren zur Darstellung eines o- Aminodiaryläthers, dadurch gekennzeichnet da,ss man ein Alkalisalz von ss-Naphtol auf 3.4-Dinitro-l-chlorbenzol einwirken lässt und den erhaltenen 5-Chlor-2-nitrophenyl-ss- naphthylUher reduziert. Claim: Process for the preparation of an o-aminodiaryl ether, characterized in that an alkali salt of ß-naphthol is allowed to act on 3,4-dinitro-1-chlorobenzene and the 5-chloro-2-nitrophenyl-ss-naphthylUher obtained is reduced. Der so erhaltene 5-Chlor-2-aminophenyl- ss-naphthyläther lässt sieh aus Ligroin um- kristallisieren und schmilzt bei<B>108</B> bis<B>109 '</B> (unkorr.). Er soll als Zwischenprodukt zui Ilerstelluno- von Farbstoffen dienen. el The 5-chloro-2-aminophenyl-ss-naphthyl ether obtained in this way can be recrystallized from ligroin and melts at <B> 108 </B> to <B> 109 '</B> (uncorrupted). It is intended to serve as an intermediate product for producing dyes. el
