Description
Verfahren zur Herstellung einer Phosphor und Halogen enthaltenden organischen Ver\bofdu-ng: Es wurde gefunden, dass man zu der neuen, Phosphor und Halogen enthaltenden Verbin dung der Formel
EMI0001.0003
gelangt, wenn man 1 Mol Triisopropylphos- phit mit 1 Mol Chloral umsetzt. Die neue Ver bindung ist ein hochsiedendes öl und kann als Schädlingsbekämpfungsmittel verwendet wer den.
Die erfindungsgemässe Kondensation er folgt durch Umsetzung der Komponenten in molekularem Verhältnis unter Abspaltung von 1 Mol Isopropylchlorid. 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 80-120 erwärmt.
<I>Beispiel:</I> Zu einer Lösung von 14,7 Teilen Chloral in 40 Volumteilen Benzol wird unter Eisküh lung eine solche von 21,2 Teilen Triisopropyl- phosphit in 20 Volumteilen Benzol gegeben. Wenn keine Temperatursteigerung mehr er folgt, wird während einer Stunde auf 60 bis 70 erwärmt, wobei Isopropylchlorid ent weicht. Anschliessend wird das Lösungsmittel abdestilliert und der Rückstand im Vakuum fraktioniert. Das Kondensationsprodukt siedet einheitlich bei 96-97 /0,1 mm.
Process for the preparation of an organic compound containing phosphorus and halogen: It has been found that the new compound of the formula
EMI0001.0003
obtained if 1 mol of triisopropylphosphite is reacted with 1 mol 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 mole of isopropyl 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, hexane 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 chloral in 40 parts by volume of benzene, a solution of 21.2 parts of triisopropyl phosphite in 20 parts by volume of benzene is added with ice cooling. When the temperature no longer increases, the mixture is heated to 60 to 70 for an hour, with isopropyl chloride giving way. The solvent is then distilled off and the residue is fractionated in vacuo. The condensation product boils uniformly at 96-97 / 0.1 mm.
