Description

  

  Verfahren zur Herstellung     eines    Kondensationsproduktes.    Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Konden  sationsproduktes der Formel  
EMI0001.0002     
    dadurch gekennzeichnet,     da.ss    man ein 4-Tri       fluormethyl-4'-chlor-2'-sulfodiphenylthioäther-          2-0-aryl-urethan    in Gegenwart von Wasser  mit     4-Chlor-5-trifluormethyl-anilin    umsetzt.  



  Das neue Kondensationsprodukt bildet ein  helles, in heissem Wasser klar lösliches Kri  stallpulver, das als Mottenschutzmittel ver  wendet werden kann.  



  <I>Beispiel:</I>  Zu einer     wässrigen    Emulsion von 10 Ge  wichtsteilen des     4-Trifluormethyl-4'-ehlor-2'-          sulfodiphenylthioäther-2-0-aryl-urethans    gibt  man die berechnete Menge     4-Chlor-5-trifluor-          niethyl-anilin    und erwärmt einige Stunden im  siedenden Wasserbad.    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 3000 Teilen Wasser  von 80 bis 90  gelöst, mit wenig Tierkohle ver  setzt und heiss filtriert. Nach Zugabe von  200 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  heissem 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-trifluoromethyl-4'-chloro-2'-sulfodiphenylthioether-2-0-aryl-urethane is reacted in the presence of water with 4-chloro-5-trifluoromethyl-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.



  <I> Example: </I> The calculated amount of 4-chloro-5- is added to an aqueous emulsion of 10 parts by weight of 4-trifluoromethyl-4'-chloro-2'-sulfodiphenylthioether-2-0-aryl-urethane trifluoro-niethyl-aniline and heated for a few 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 3000 parts of water from 80 to 90, ver with a little animal charcoal and filtered hot. After the addition of 200 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 light-colored powder that is clearly soluble in hot water.
