Description

  

  Verfahren zur Herstellung eines     Kondensationsproduktes.       Degenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Konden  sationsproduktes der Formel  
EMI0001.0002     
         dadureh    gekennzeichnet, dass man ein 4-Tri       fluornietliyl-4'-clilor-2'-sulfodipheiiyläther-2-0-          ary1-111.c>tlian    in Gegenwart von 'Wasser mit  0<B>3</B>     A-Diehlor-anilin        umsetzt.     



       1)as    neue Kondensationsprodukt bildet ein       hellet,    in heissem Wasser klar     löslichesKristall.-          pLilver,    das als     :lfottensehutzmittel    verwendet  werden kann.  



       Beispiel:     Zu     einer        wässrigen    Emulsion von 20     Ge-          wiehtsteilen    des     4-Trifluorm.ethyl-4'-ehlor-2'-          sulfodipheiiyläther-2-0-ary1-urethans    gibt man.  die     bereehnete    Menge     3,4-Diehlor-anilin    und  erwärmt einige Stunden im siedenden     Wasser-          Ijad.    Der Kolbeninhalt wird mit     Koehsalz    ge-    sättigt.

   Hierbei scheidet sich ein öl aus, das  beim Stehen über Nacht fest     wird.    Das Kon  densationsprodukt wird in Wasser von 80 bis  90  gelöst, mit wenig Tierkohle versetzt und  heiss filtriert. Nach     Zugabe    von gesättigter  Kochsalzlösung scheidet sich das Kondensa  tionsprodukt in guter Reinheit und Ausbeute  aus.  



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



  Process for the production of a condensation product. The subject of the present patent is a process for the preparation of a condensation product of the formula
EMI0001.0002
         dadureh characterized that a 4-trifluoronietliyl-4'-clilor-2'-sulfodipheiiyläther-2-0-ary1-111.c> tlian in the presence of 'water with 0 <B> 3 </B> A-Diehlor -aniline converts.



       1) The new condensation product forms a light-colored, clear-soluble crystal in hot water - pLilver, which can be used as a soot detergent.



       Example: To an aqueous emulsion of 20 parts by weight of 4-trifluoromethyl-4'-chloro-2'-sulfodipheiiyläther-2-0-ary1-urethane is added. the raked amount of 3,4-diehloraniline and heated for a few hours in the boiling water Ijad. The contents of the flask are saturated with salt.

   An oil separates out and solidifies when standing overnight. The condensation product is dissolved in water from 80 to 90, mixed with a little animal charcoal and filtered hot. After adding 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 dissolves clearly in hot water.
