Description

  

      verfahren    zur Herstellung eines Kondensationsproduktes.    Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Konden  sationsproduktes der Formel  
EMI0001.0002     
    dadurch gekennzeichnet, dass man ein 4,4'  Diehlor -     2'-        sulfodiphenylthioäther    - 2 - 0 -     aryl-          urethan    in Gegenwart von Wasser mit     2-Chlor-          .)-triflnormethyl-anilin    umsetzt.  



  Das neue Kondensationsprodukt bildet ein       Helles,    in heissem Wasser klar lösliches Kri  stallpulver, das als     'Mottensehutzmittel    ver  wendet werden kann.         Beispiel:       Zu einer     wässrigen    Emulsion von 12 Ge  wichtsteilen des     4,4'-Dichlor-2'-sulfodiphenyl-          thioäther-2-0-aryl-urethans    gibt man die be  rechnete Menge     2-Chlor-5-trifluormethyl-anilin     und erwärmt 5 Stunden im siedenden Wasser-         bad.    Der Kolbeninhalt wird mit     Kochsalz    ge  sättigt. Hierbei scheidet sich ein Öl aus, das  beim Stehen über Nacht fest wird.

   Das Kon  densationsprodukt wird in 3500 Teilen Wasser  von 80 bis 90  gelöst, mit wenig Tierkohle  versetzt und heiss filtriert.     Naeh    Zugabe von  100 Teilen gesättigter     Kochsalzlösung    scheidet  sich das     Kondensationsprodukt    in guter Rein  heit und Ausbeute aus.  



  Das neue Kondensationsprodukt stellt nach  dem Trocknen und Mahlen ein helles, in hei  ssem Wasser klar lösliches Pulver dar.



      process for the production of a condensation product. The present patent relates to a process for the preparation of a condensation product of the formula
EMI0001.0002
    characterized in that a 4,4 'diehlor - 2'-sulfodiphenylthioether - 2 - 0 - aryl urethane is reacted in the presence of water with 2-chloro -.) - triflnormethyl aniline.



  The new condensation product forms a pale crystal powder which is clearly soluble in hot water and which can be used as a moth repellent. Example: The calculated amount of 2-chloro-5-trifluoromethyl-aniline is added to an aqueous emulsion of 12 parts by weight of 4,4'-dichloro-2'-sulfodiphenyl thioether-2-0-aryl urethane and heated 5 Hours in a boiling water bath. The contents of the flask are saturated with table salt. An oil separates out and solidifies when standing overnight.

   The condensation product is dissolved in 3500 parts of water from 80 to 90, mixed with a little animal charcoal and filtered hot. After adding 100 parts of saturated sodium chloride solution, the condensation product separates out in good purity and yield.



  After drying and grinding, the new condensation product is a pale powder that is clearly soluble in hot water.
