Description

  

  Verfahren zur Herstellung eines     Kondensationsproduktes.       Gegenstand vorliegenden Patentes ist ein  Verfahren zur Herstellung eines Konden  sationsproduktes. Das Verfahren ist dadurch  gekennzeichnet, dass man     4,4'-Di-(biguanido)-          diphenyl    mit     2,4-Dinitro-chlorbenzol    umsetzt.  



  Das     Kondensationsprodukt,    ein gelb  braunes, in konzentrierten Säuren lösliches  Pulver, hat einen Zersetzungspunkt von     230 .     Es soll als Pflanzenschutzmittel Verwendung  finden.  



  <I>Beispiel:</I>  80 Teile     4,4'-Di-(biguanido)-diphenyl,     90 Teile     2,4-Dinitro-chlorbenzol    und 50 Teile  Soda werden in 500 Teilen Chlorbenzol bis  zur Beendigung der Umsetzung (zirka 20  Stunden) rückfliessend gekocht. Man erhält  nach dem Abkühlen ein     gelbbraunes    Pulver,       wclehes        a,bfiltriert,    mit     Chlorbenzol    und dar-    auf gründlich mit Wasser gewaschen und an  schliessend getrocknet wird. Es ist in konzen  trierten Säuren löslich und zersetzt sich bei       280 .  



  Process for the production of a condensation product. The subject of the present patent is a process for the production of a condensation product. The process is characterized in that 4,4'-di- (biguanido) -diphenyl is reacted with 2,4-dinitro-chlorobenzene.



  The condensation product, a yellow-brown powder soluble in concentrated acids, has a decomposition point of 230. It should be used as a plant protection agent.



  <I> Example: </I> 80 parts of 4,4'-di- (biguanido) -diphenyl, 90 parts of 2,4-dinitro-chlorobenzene and 50 parts of soda are dissolved in 500 parts of chlorobenzene until the reaction is complete (approx Hours) refluxed. After cooling, a yellow-brown powder is obtained, which is filtered, washed with chlorobenzene and then thoroughly with water and then dried. It is soluble in concentrated acids and decomposes at 280.
