Description

  

  Verfahren zur     Herstellung    eines     Kondensationsproduktes.       Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Konden  sationsproduktes der Formel  
EMI0001.0003     
    dadurch gekennzeichnet, dass man ein     4,4',5'-          Triehlor    -     2'-        sulfodiphenyläther    - 2 -     0-aryl-ure-          than    in Gegenwart von Wasser mit     3-Trifhtor-          methyl-4-chlor-anilinumsetzt.     



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



  <I>Beispiel:</I>  Zu einer     wässrigen    Emulsion von 15 Ge  wichtsteilen des     4,4',5'-Trichlor-2'-sulfodiphe-          nyläther-2-0-aryl-urethans    gibt man die be  rechnete Menge     3-Trifluormethyl-4-chlor-          anilin    und     erwärmt    einige Stunden im sieden  den 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     Lmd    heiss filtriert.

   Nach     Zugabe.    von  65 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
EMI0001.0003
    characterized in that a 4,4 ', 5'-triehlor-2'-sulfodiphenyl ether-2-0-aryl-urethane is reacted with 3-trifhtoremethyl-4-chloro-aniline in the presence of water.



  The new condensation product forms a beautiful, light-colored crystal powder which is clearly soluble in hot water and which can be used as a moth repellent.



  <I> Example: </I> To an aqueous emulsion of 15 parts by weight of 4,4 ', 5'-trichloro-2'-sulfodiphenyl ether-2-0-aryl-urethane is added the calculated amount of 3- Trifluoromethyl-4-chloroaniline and heated the water bath for a few hours in the boil. 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, and a little animal charcoal is added to Lmd and filtered hot.

   After adding. from 65 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.
