Description
Verfahren zur Herstellung einer Phosphor und Halogen enthaltenden organischen Verbindung. Es wurde gefunden, dass span zu der neuen, Phosphor und Halogen enthaltenden Verbin dung der Formel
EMI0001.0004
gelangt, wenn -man 1 Mol Trimethylphosphit mit 1 Mol Chloral umsetzt. Die neue Verbin dung ist ein hochsiedendes Öl Lind kann als Schädlingsbekämpfungsmittel verwendet wer den.
Die erfindungsgemässe Kondensation er folgt durch Umsetzung der Komponenten in molekularem Verhältnis unter Abspaltung von 1 Mol Methylchlorid. Die Reaktion verläuft exotherm, so dass die Komponenten zweck mässig unter Kühlung und mit inerten Lö sungsmitteln, wie Benzol, Toluol, Äther, Di- oxan, IIexan oder tiefsiedendem Benzin, ver dünnt vereinigt werden. Zur Beendigung der Umsetzung wird die Reaktionsmischung vor teilhaft auf 80-120 erwärmt.
<I>Beispiel:</I> Zu einer Lösung von 14,7 Teilen Ohloral in 40 Volumteilen Benzol wird unter Eisküh- hing eine solche von 12,4 Teilen Trimethyl- phosphit in 20 Volumteilen Benzol gegeben. Wenn keine Temperatursteigerung mehr er folgt, wird während einer Stunde auf 60 bis 70 erwärmt, wobei Methylchlorid entweicht. Anschliessend wird das Lösungsmittel abdestil- liert und der Rückstand im Vakuum fraktio niert.
Das Kondensationsprodukt siedet ein heitlich bei 85-87 /0,2 mm.
Process for the preparation of an organic compound containing phosphorus and halogen. It was found that the new compound containing phosphorus and halogen of the formula
EMI0001.0004
arrives when 1 mole of trimethyl phosphite is reacted with 1 mole of chloral. 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 methyl chloride. The reaction is exothermic, so that the components are conveniently combined with cooling and diluted with inert solvents such as benzene, toluene, ether, dioxane, IIexane or low-boiling gasoline. To complete the reaction, the reaction mixture is partially heated to 80-120.
<I> Example: </I> To a solution of 14.7 parts of Ohloral in 40 parts by volume of benzene, a solution of 12.4 parts of trimethylphosphite in 20 parts by volume of benzene is added while cooling with ice. When the temperature does not increase any more, the mixture is heated to 60 to 70 for one hour, with methyl chloride escaping. The solvent is then distilled off and the residue is fractionated in vacuo.
The condensation product boils uniformly at 85-87 / 0.2 mm.
