Description / Table of Contents:
Reaction of Trimethylphosphate with Hexamethyl Phosphoric Acid Triamide - a Versatile Synthesis of a CyclotriphosphateThe reaction of the two title compounds 5 and 6 in the mole ratio of 2:1 during two weeks at 150°C leads predominantly to tetramethylammonium cyclotriphosphate 9 and, as a consequence of the cleavage of trimethylamine and dimethyl ether, to small amounts of an ultraphosphate 15, which also contains cyclotriphosphate rings. 15 can be hydrolysed and neutralized with tetramethylammoniumhydroxide to yield pure 9 in the form of its trihydrate.
Notes:
Die beiden Titelverbindungen 5 und 6 reagieren miteinander im Molverhältnis 2:1 bei Temperaturen um 150°C im Verlaufe zweier Wochen im wesentlichen zum Tetramethylammonium-Salz der Cyclotriphosphorsäure 9 und durch Abspaltung von Trimethylamin und Dimethylether unter Bildung geringer Mengen eines Ultraphosphats 15, das ebenfalls Cyclotriphosphatringe enthält. Nach Hydrolyse und Neutralisation mittels Tetramethylammoniumhydroxids kann reines 9 in Form des Trihydrats isoliert werden.
