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     2,4,6-Trinitrochlorbenzol        (Pi-          krylchlorid)    umsetzt.  



  Das Kondensationsprodukt, ein tiefrotes  Pulver, hat einen Zersetzungspunkt von 230 .  Es soll als Pflanzenschutzmittel Verwendung  finden.  



  <I>Beispiel:</I>  10 Teile 4,4' -     Di    -     (bigu@anido)    -     diphenyl     werden in 100 Teilen Chlorbenzol an  geschlämmt, 5,7 Teile Soda zugegeben und  bei 90  mit einer Lösung von 15 Teilen       2,4,6-Trinitrochlorbenzol        (Pikrylchlorid)    in  wenig Chlorbenzol vermischt. Es tritt sofort  Reaktion ein, wobei die Suspension sich rot  braun färbt. Es wird 14 Stunden bei 90 bis  100  und noch 2 Stunden bei 120  gerührt.    Nach dem Erkalten,     Abfiltrieren,    Waschen  und Trocknen erhält man ein Kondensations  produkt von     tiefroter    Farbe, das sich beim  Erhitzen bei     2'310     langsam zersetzt.



  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 2,4,6-trinitrochlorobenzene (picryl chloride).



  The condensation product, a deep red powder, has a decomposition point of 230. It should be used as a plant protection agent.



  <I> Example: </I> 10 parts of 4,4 '- di - (bigu @ anido) - diphenyl are slurried in 100 parts of chlorobenzene, 5.7 parts of soda are added and at 90 with a solution of 15 parts 2, 4,6-trinitrochlorobenzene (picryl chloride) mixed in a little chlorobenzene. A reaction occurs immediately, with the suspension turning red-brown. It is stirred for 14 hours at 90 to 100 and a further 2 hours at 120. After cooling, filtering off, washing and drying, a condensation product is obtained which is deep red in color and slowly decomposes when heated at 2,310.
