      Verfahren    zur Herstellung     eines    Kondensationsproduktes.         Gegenstand    vorliegenden Patentes ist ein  Verfahren zur Herstellung     eines        Kondensa-          tionsproduktes.    Das     Verfahren    ist dadurch  gekennzeichnet, dass man 1     Mol        einer    den       C12C=CCl-CH-'Rest    abgebenden Verbin  dung mit 2     Mol    Benzol kondensiert. Als den       Trichlorallylidenrest    abgebende Verbindun  gen können z.

   B.     Trichloracrolein    oder dessen  reaktionsfähige     Derivate,        wie    z. B.     Penta-          chlorpropen,    verwendet werden. Die entstan  dene neue Verbindung, das     a,a-Bis-phenyl-          ss,y,y-triehlor-propen,    siedet bei 146 bis 147   bei 0;15 mm     Druck.-    Sie soll als Insektizid  Verwendung     finden.       <I>Beispiel:

  </I>    30-     Teile        Pentachlorpropen    werden     mit     120 Teilen Benzol     gemischt    und     bei    0 bis 5   6     Teile        Aluminiumchlorid    zugesetzt. Nach  kurzer     Zeit        tritt    starke Reaktion unter Auf  schäumen ein, wobei die Temperatur auf ca.       20     steigt.

   Man rührt nach Abklingen der         Reaktion    noch 10     Stunden        bei        7Zimmertem-          peratur    weiter und giesst     dann        das        Reaktions-          produkt    in     Wasser.        Überschüssige    Ausgangs  stoffe werden mit     Wasserdampf    abgetrieben  und der Rückstand im Hochvakuum destil  liert.

   Das     a,a-Bis-phenyl-ss,y,y-trnchlor-propen     ist eine farblose, dickliche     Flüssigkeit    vom       Siedepunkt    146 bis 147  bei 0,15     mm.        Hg.  



      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 1 mol of a compound releasing the C12C = CCl-CH- 'radical is condensed with 2 mol of benzene. As the Trichlorallylidenrest releasing compounds can, for.

   B. Trichloracrolein or its reactive derivatives, such as. B. pentachloropropene can be used. The resulting new compound, a, a-bis-phenyl-ss, y, y-triehloropropene, boils at 146 to 147 at 0.15 mm pressure. It is said to be used as an insecticide. <I> example:

  </I> 30 parts of pentachloropropene are mixed with 120 parts of benzene and added at 0 to 5 6 parts of aluminum chloride. After a short time, a strong reaction occurs with foaming, the temperature rising to approx.

   After the reaction has subsided, stirring is continued for 10 hours at 7 room temperature and the reaction product is then poured into water. Excess starting materials are driven off with steam and the residue is distilled in a high vacuum.

   The a, a-bis-phenyl-ss, y, y-trnchloro-propene is a colorless, thick liquid with a boiling point 146 to 147 at 0.15 mm. Ed.
