Description

Verfahren zur Herstellung von Äthyleniminverbindungen Es ist schon vorgeschlagen worden, Säurehalogenide, wie Phosphoroxvchlorid, sowie Verbindungen der Formel' in der R einen einwertigen, aliphatischen, isocyclischen oder heterocyclischen Rest, mit Ausnahme von a, ß-Alkyleniminresten, bedeutet, mit a, ß-Alkyleniminen in Gegenwart von säurebindenden Mitteln umzusetzen (vgl. Patente 863 055 und 854 65i). Dabei entstehen beispielsweise Verbinduneen der Formel wobei X auf Homologe und Derivate hinweist.Process for the preparation of ethyleneimine compounds It has already been proposed to use acid halides, such as phosphorus oxychloride, and compounds of the formula ' in which R is a monovalent, aliphatic, isocyclic or heterocyclic radical, with the exception of α, β-alkylenimine radicals, means to react with α, β-alkylenimines in the presence of acid-binding agents (cf. Patents 863 055 and 854 65i). This creates compounds of the formula, for example where X indicates homologues and derivatives.

Als säurebindende Mittel werden tertiäre Amine, wie z. B. Triäthylamin, genannt. Es wurde nun gefunden, daß die Umsetzung derartiger Säurehalogenide sehr glatt und mit hervorragenden Ausbeuten verläuft, wenn man an Stelle der tertiären Amine wasserfreies Ammoniak als säurebindendes Mittel verwendet. Eine Substitution des Ammoniaks durch die Säurehalogenide findet dabei nicht statt. Die Umsetzung wird zweckmäßig in indifferenten Lösungsmitteln, wie Benzol, Chlorbenzol u. a., ausgeführt.As acid-binding agents, tertiary amines, such as. B. triethylamine, called. It has now been found that the implementation of such acid halides is very runs smoothly and with excellent yields if one takes the place of the tertiary Amines anhydrous ammonia is used as an acid-binding agent. A substitution of the ammonia through the acid halides does not take place. The implementation is useful in inert solvents such as benzene, chlorobenzene and others, executed.

Beispiele z. Zu. 1954 Gewichtsteilen Äthylenimin, gelöst in gooo Gewichtsteilen Benzol, läßt man allmählich bei 1o bis z5° 2295 Gewichtsteile Phosphoroxychlorid, gelöst in 45oo Gewichtsteilen Benzol, zufließen. Während des Einlaufens des Phosphoroxychlorids wird ein trockener Ammoniakstrom eingeleitet, und zwar in der Weise, daß die Lösung stets alkalisch reagiert. Nach Beendigung des Einlaufens wird mehrere Stunden nachgerührt, Ammonüimchlorid abfiltriert und nun Benzol unter vermindertem Druck abdestilliert. Es hinterbleibt Tri-(äthylenimio)-phosphinoxyd, das nach kurzer Zeit erstarrt.Examples e.g. To. 1954 parts by weight of ethylene imine, dissolved in 100 parts by weight Benzene, one leaves gradually at 10 to z5 ° 2295 parts by weight of phosphorus oxychloride, dissolved in 45oo parts by weight of benzene. During the break-in of the phosphorus oxychloride a stream of dry ammonia is introduced, in such a way that the solution always reacts alkaline. After finishing the running-in will be several Stirred for hours, ammonium chloride filtered off and then benzene under reduced pressure Distilled pressure. Tri- (äthylenimio) -phosphinoxyd remains, which after a short time Time freezes.

Die Ausbeute beträgt 235o Gewichtsteile = go °/o der Theorie.The yield is 2350 parts by weight = 100% of theory.

In gleicher Weise können die in dem Patent 854 651 angeführten Säurechloride, wie Phosphorsäurediäthylamiddichlorid, Phosphorsäureäthylaniliddichlorid, verwendet werden.In the same way, the acid chlorides listed in the patent 854 651, such as Phosphorsäurediäthylamiddichlorid, Phosphorsäureäthylaniliddichlorid used will.

2. Zu 48 Gewichtsteilen Äthylenimin in 500 @Gewichtsteilen Benzol läBt man unter Rühren langsam bei 2o bis 25° 95 Gewichtsteile Phosphorsäurediäthylamiddichlorid in ioo Gewichtsteilen Benzol zutropfen.-Während des Einlaufens des Dichlorids wird ein trockener Ammoniakstrom eingeleitet, und zwar in der Weise, daB die Lösung stets" einen geringen ÜberschuB an Ammoniak enthält: Nach Beendigung des Einlaufens wird x Stunde nachgerührt, das Ammoniumchlorid abfiltriert, das Benzol abdestilliert und das Phosphorsäurediäthylamiddiäthylenimid im Vakuum destilliert, Kpo,s 95 bis g6°.. Die Ausbeute beträgt 92 bis 93 % der Theorie. 2. 95 parts by weight of phosphoric acid diethylamide dichloride in 100 parts by weight of benzene are slowly added dropwise to 48 parts by weight of ethyleneimine in 500 parts by weight of benzene with stirring at 20-25 ° Solution always "contains a small excess of ammonia: After the run-in has ended, stirring is continued for x hours, the ammonium chloride is filtered off, the benzene is distilled off and the phosphoric acid diethylamiddiäthylenimid is distilled in vacuo, Kpo, s 95 to g6 ° .. The yield is 92 to 93% of the Theory.

3. Zu 48 Gewichtsteilen Äthylenimin, gelöst in 5oo Gewichtsteilen Benzol, läBt man allmählich bei 15 bis 2o° 81 Gewichtsteile Phosphorsäureäthylesterdichlorid in ioo Gewichtsteilen Benzol einlaufen. Während des Einlaufens wird ein trockener Ammoniakstrom eingeleitet, und zwar in der Weise, daB die Lösung stets alkalisch reagiert. Nach Beendigung des Einleitens wird kurze Zeit nachgerührt, das Ammoniumchlorid abfiltriert und das Benzol unter vermindertem Druck abdestilliert. Es hinterbleibt Phosphorsäureäthylesterdiäthylenimid, Kpl 96 bis g8°. Die Ausbeute beträgt 8o % der Theorie.3. To 48 parts by weight of ethyleneimine, dissolved in 500 parts by weight of benzene, 81 parts by weight of ethyl phosphoric ester dichloride in 100 parts by weight of benzene are gradually allowed to run in at 15 to 20 °. During the run-in, a stream of dry ammonia is introduced in such a way that the solution always gives an alkaline reaction. After the introduction has ended, the mixture is stirred for a short time, the ammonium chloride is filtered off and the benzene is distilled off under reduced pressure. It remains phosphoric acid ethyl ester diethylenimide, Kpl 96 to g8 °. The yield is 80% of theory.
