Description

  

  Verfahren zur Darstellung eines     Dinitrolialogenaryles.       Gegenstand der vorliegenden Erfindung  ist ein Verfahren zur Darstellung eines     Di-          nitrohalogena.ryl,-,    folgender Konstitution:  
EMI0001.0004     
    welches dadurch gekennzeichnet ist,     dass    man       1-Chlor-2.4-dinitro-6-be.nzoyle,hlorid    mit       Monomethylanilin    in wässeriger Lösung in       Gegenwaft    eines säurebindenden Mittels kon  densiert.  



  <I>Beispiel:</I>  <B>265</B> Gewichtsteile  
EMI0001.0009     
    werden unter Zusatz von Wasser mit     214     Gewichtsteilen     Monomethylanilin   <B>(=</B> 2     Mol.)     bei gewöhnlicher oder erhöhter Temperatur  behandelt. Nach beendeter Reaktion wird  das überschüssige     Monometllylanilin    heraus  gelöst und das Reaktionsprodukt von     der     Formel  
EMI0001.0015     
    aus     Toluol    umkristallisiert. Es stellt einen  farblosen Körper dar.

   An Stelle des zur  Säurebindung im     Überschuss    angewendeten       Monomethylanilins    können auch andere  säurebindende Mittel treten, wie zum Bei  spiel Kreide,     Natriumacetat        usw.  



  Process for the preparation of a Dinitrolialogenaryles. The present invention relates to a process for the preparation of a Di- nitrohalogena.ryl, -, the following constitution:
EMI0001.0004
    which is characterized in that 1-chloro-2,4-dinitro-6-be.nzoyle, chloride is condensed with monomethylaniline in aqueous solution in the presence of an acid-binding agent.



  <I> Example: </I> <B> 265 </B> parts by weight
EMI0001.0009
    are treated with the addition of water with 214 parts by weight of monomethylaniline <B> (= </B> 2 mol.) at ordinary or elevated temperature. After the reaction has ended, the excess Monometllylanilin is dissolved out and the reaction product of the formula
EMI0001.0015
    recrystallized from toluene. It represents a colorless body.

   Instead of the excess monomethylaniline used for acid binding, other acid binding agents can also be used, such as chalk, sodium acetate, etc.
