Description
Verfahren zur Herstellung eines basisch substituierten Carbonsäureamids. Es wurde gefunden, dass man zu einem basisch substituierten Karbonsäureamid ge langen kann, wenn man einen reaktions fähigen Ester des Diäthylaminoäthanols auf ein Metallderivat des Ölsäureamids einwir ken lässt.
Das so erhaltene Oleyl-diäthyläthylen- diamid ist identisch mit der im Schweizer. Patent Nr. 107 202 beschriebenen Verbin dung.
Beispiel: 28,1 Teile Ölsäureamid werden in 100 Teilen Xylol mit 4,4 Teilen Natrium- i mid bis zur Be endigung 21 der Ammoniak entwicklung erwärmt. Nun fügt man 14 Teile Chloräthyldiäthylamin zu und er wärmt weiter. Nach erfolgter Reaktion wird das Xylol im Vakuum abdestilliert und der Rückstand in Äther aufgenommen. Die filtrierte Ätherlösung wird eingedunstet. Das zurückbleibende Oleyldiäthyläthylen- diamid zersetzt sich bei der Destillation un ter gewöhnlichem Druck. Im Hochvakuum bei 0,08 mm siedet es bei 190'.
An Stelle von Chloräthyldiäthylamin können auch andere reaktionsfähige Ester des Diäthylaminoäthanols, zum Beispiel der Bromwasserstoff-, der Jodwasserstoff- oder der Toluolsulfosäureester Verwendung fin den. Zur Herstellung der Metallverbindung des Karbonsäüreamids kann man auch andere Metallamide, wie zum Beispiel Ka lium- oder Calciumamid, Metallalkoholate, wie zum Beispiel Natrium- oder Kalium alkoholat, oder reaktionsfähige Metalle, wie zum Beispiel Natrium, Kalium usw., ge brauchen.
Process for the preparation of a basic substituted carboxamide. It has been found that a basic substituted carboxamide can be obtained if a reactive ester of diethylaminoethanol is allowed to act on a metal derivative of oleic acid amide.
The oleyl diethylethylene diamide obtained in this way is identical to that in the Swiss. Patent No. 107 202 connection described.
Example: 28.1 parts of oleic acid amide in 100 parts of xylene are heated with 4.4 parts of sodium imide until the evolution of ammonia has ended. Now you add 14 parts of chloroethyl diethylamine and he continues to warm. After the reaction has taken place, the xylene is distilled off in vacuo and the residue is taken up in ether. The filtered ethereal solution is evaporated. The remaining oleyl diethylethylene diamide decomposes in the distillation under normal pressure. In a high vacuum at 0.08 mm it boils at 190 '.
Instead of chloroethyl diethylamine, other reactive esters of diethylaminoethanol, for example hydrogen bromide, hydrogen iodide or toluenesulfonic acid ester, can be used. To produce the metal compound of the carbonic acid amide, other metal amides, such as, for example, potassium or calcium amide, metal alcoholates, such as, for example, sodium or potassium alcoholate, or reactive metals, such as, for example, sodium, potassium, etc., can be used.
