Description

  

  <B>Verfahren</B>     zur        Herstellung   <B>einer Phosphor und Halogen enthaltenden organischen</B>     Verhindung:       Es wurde     gefunden,    dass man zu der neuen,  Phosphor und Halogen enthaltenden Verbin  dung der Formel  
EMI0001.0005     
    gelangt,     wenn    man 1     Mol        Triäthylphosphit     mit 1     Mol        4-Methyl-(o-trichloracetophenon    um  setzt. Die neue Verbindung ist ein hochsieden  des Öl     und    kann als Schädlingsbekämpfungs  mittel verwendet werden.  



  Die erfindungsgemässe Kondensation er  folgt durch Umsetzung der Komponenten in  molekularem Verhältnis unter Abspaltung von  1     Mol        Äthylchlorid.    Die Reaktion verläuft       exotherm,    so dass die Komponenten zweck  mässig unter Kühlung und mit     inerten    Lö  sungsmitteln, wie Benzol,     Toluol,    Äther,     Di-          oxan,        Hexan    oder tiefsiedendem Benzin, ver  dünnt vereinigt werden. Zur Beendigung der  Umsetzung wird die Reaktionsmischung vor  teilhaft auf 80 bis 120  erwärmt.  



  <I>Beispiel:</I>  Zu einer Lösung von 23,6 Teilen     4-Methyl-          (a)-triehloracetophenon    in 10     Volumteilen    Ben  zol wird allmählich eine solche von 16,6 Tei  len     Triäthylphosphit    in 10     Volumteilen    Benzol  gegeben,     wobei    durch mässiges Kühlen die    Temperatur unter 60  gehalten wird.

       Wein     die Temperatur nicht mehr steigt und die an  fangs lebhafte Gasentwicklung aufgehört hat,  wird noch 30 Minuten auf dem Dampfbad er  hitzt     lind    anschliessend das Benzol im     Vakuiun          abdestilliert.    Aus dem Rückstand werden  durch Destillation 19,4 Teile des Kondensa  tionsproduktes als farbloses, bei l59-160 /  0,06 mm siedendes Öl gewonnen.



  <B> Process </B> for the production <B> of an organic compound containing phosphorus and halogen </B>: It has been found that the new compound of the formula containing phosphorus and halogen
EMI0001.0005
    obtained when 1 mol of triethyl phosphite is reacted with 1 mol of 4-methyl- (o-trichloroacetophenone. 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. To complete the reaction, the reaction mixture is heated to 80 to 120 before some.



  <I> Example: </I> To a solution of 23.6 parts of 4-methyl- (a) -triehloracetophenone in 10 parts by volume of benzene, a solution of 16.6 parts of triethyl phosphite in 10 parts by volume of benzene is gradually added, with through moderate cooling the temperature is kept below 60.

       If the temperature no longer rises and the initially lively evolution of gas has ceased, it is heated for another 30 minutes on the steam bath and then the benzene is distilled off in a vacuum. 19.4 parts of the condensation product are obtained from the residue by distillation as a colorless oil boiling at 159-160 / 0.06 mm.
