Description

  

  <B>Verfahren zur</B>     Herstellung   <B>einer Phosphor und Halogen enthaltenden organischen Verbindung.</B>    Es wurde gefunden, dass man zu der neuen,  Phosphor und Halogen enthaltenden Verbin  dung der Formel  
EMI0001.0002     
    gelangt, wenn man 1     lIol        Triäthylphosphit     mit 1     Mol        Trichloressigsäure-thioäthylester     umsetzt. Die neue Verbindung ist ein hochsie  dendes Öl und     kann    als Schädlingsbekämp  fungsmittel verwendet werden.  



  Die erfindungsgemässe Kondensation er  folgt durch     Umsetzung    der Komponenten in  molekularem Verhältnis     unter    Abspaltung von  1     Mol        Äthylchlorid.    Die Reaktion verläuft     exo-          therm,    so dass die Komponenten zweckmässig  unter     Kühlung    und mit     inerten    Lösungsmit  teln, wie Benzol,     Toluol,    Äther,     Dioxan,        Hexan     oder tiefsiedendem     Benzin,    verdünnt vereinigt  werden.

   Zur Beendigung der Umsetzung wird  die Reaktionsmischung vorteilhaft auf 80 bis  120      erwärmt.     



  <I>Beispiel:</I>  <B>20,7</B> Teile     TrichloressigsäLire-thioäthylester     werden mit 16,6 Teilen     Triäthylphosphit    ver  mischt und stehengelassen. Nach kurzer Zeit  beginnt die Reaktion,     mid    die Temperatur  wird durch Kühlen bei 60-70 <B>0</B> gehalten.    Wenn keine     Temperatursteigerung    mehr er  folgt,     wird    während 2 Stunden auf 70-80   erhitzt. Bei der anschliessenden Destillation  im     Vakuum    erhält man das Kondensationspro  dukt, das ein farbloses, bei 117-119 /0,2 mm  siedendes Öl mit schwachem,     mercaptanähnli-          chem    Geruch ist.



  <B> Process for </B> the production <B> of an organic compound containing phosphorus and halogen. </B> It has been found that the novel compound of the formula
EMI0001.0002
    obtained if 1 lol of triethyl phosphite is reacted with 1 mol of trichloroacetic acid thioethyl ester. The new compound is a high boiling oil and can be used as a pesticide.



  The inventive condensation he follows by reacting the components in a molecular ratio with elimination of 1 mol of ethyl chloride. The reaction is exothermic, so that the components are advantageously combined with cooling and diluted with inert solvents such as benzene, toluene, ether, dioxane, hexane or low-boiling gasoline.

   The reaction mixture is advantageously heated to 80 to 120 to terminate the reaction.



  <I> Example: </I> <B> 20.7 </B> parts of trichloroacetic acid thioethyl ester are mixed with 16.6 parts of triethyl phosphite and left to stand. After a short time the reaction begins, and the temperature is kept at 60-70 ° by cooling. If there is no longer any increase in temperature, it is heated to 70-80 for 2 hours. The subsequent distillation in vacuo gives the condensation product, which is a colorless oil boiling at 117-119 / 0.2 mm with a faint, mercaptan-like odor.
