Description

  

  Verfahren zur Darstellung eines     Chlorierungsproduktes    des     Netimides    des       3-Chlor-aconapht-perl-Indandions.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Darstellung eines     Chlorierungs-          produktes    des     Ketimides    des     3-Ohlor-acenapht-          pori-indandions,    welches dadurch gekennzeich  net,     dass    man das     Ketimid    des     3-Chlor-ace-          napht-peri-indandions    mit     chlorierenden    Mit  teln behandelt,

    Das neue Produkt ist ein gelblich weisser  Körper, der bei etwa<B>180 0</B>     C    unter Zersetzung  schmilzt.  



  <I>Beispiel:</I>  <B>5</B> Gewichtsteile salzsaures     Ketimid    des       3-Chlor-acer)apht-peri-indandions

    (siehe Patent     Nr.   <B>153817)</B> werden in einer  mit dem     gle'Ichen    Volumen Wasser verdünn  ten Salzsäure fein verteilt und mit etwa         2,5    Gewichtsteilen     Kaliumehlorat    versetzt  Die Reaktionstemperatur ist 20-30'<B>C.</B> Bei  gutem Rühren ist nach<B>2-3</B> Stunden alles  umgesetzt. Das gelblich weisse     Chlorierungs-          produkt    wird abgesaugt, neutral gewaschen  und getrocknet. Es schmilzt unter Zersetzung  bei etwa<B>180 0 C.</B>



  Process for the preparation of a chlorination product of the netimide of 3-chloro-aconapht-perl-indanedione. The subject of this additional patent is a process for the preparation of a chlorination product of the ketimide of 3-chloro-acenapht-pori-indandione, which is characterized in that the ketimide of 3-chloro-acenapht-peri-indandione is mixed with chlorinating agents treated,

    The new product is a yellowish-white body that melts at around <B> 180 0 </B> C with decomposition.



  <I> Example: </I> <B> 5 </B> parts by weight of hydrochloric acid ketimide of 3-chloro-acer) apht-peri-indandione
EMI0001.0017
    (see patent no. 153817) are finely distributed in hydrochloric acid diluted with the same volume of water and mixed with about 2.5 parts by weight of potassium chlorate. The reaction temperature is 20-30 ° C. </B> With good stirring, everything is implemented after <B> 2-3 </B> hours. The yellowish white chlorination product is filtered off with suction, washed neutral and dried. It melts with decomposition at about <B> 180 0 C. </B>
