Description

Verfahren zur Darstellung von Aminotetrazol. A. Hantzsch & J. S. Smythe- haben Aminotctrazol ans Cvanainid und Stickstoffwasserstoffsäure in wässeriger Lösung gewonnen. Es wurde nun die bemerkenswerte Beobachtung gemacht. claß das bequem zu-0 (r ngliche Dicvandiainid mit wässeriger Stickstoffwasserstoff säure glatt Aininotetrazol liefert: Beispiel: Eine «-arm gesättigte wässerige Lösung von 84 Teilen Dicvandiainid wird mit einer r jlirozentigen wässerigen Lösung von aoo Teilen Stickstoffwasserstoffsäure zusammengebracht. Aminotetrazol scheidet sich nach längerem Stehen in Kristallen ab, der Rest wird durch Eindampfen der Lösung unter Zurückgewinnung der überschüssigen Stick- stoffwasserstoffsäure erhalten. Die Ausbeute ist quantitativ. Process for the preparation of aminotetrazole. A. Hantzsch & JS Smythe- have obtained aminotctrazole from cvanainide and hydrazoic acid in aqueous solution. The remarkable observation has now been made. The dicvandiainide, which can be easily obtained with aqueous hydrazoic acid, gives ainotetrazole smoothly: Example: A poorly saturated aqueous solution of 84 parts of dicvandiainide is brought together with a three-centimeter aqueous solution of aoo parts of hydrazoic acid. Aminotetrazole separates out in crystals after standing for a long time, the remainder is removed by evaporation of the solution with recovery of the excess nitrogen obtained hydrofluoric acid. The yield is quantitative.
