Azidoazide Azide o 1-Diazidocarbamoyl-5-azidotetrazole (neop. Azidoazide azide, azidoazide, inglese azidoazide azide, abbreviato AA) è un composto organico eterociclico con formula molecolare C2N14. A causa di un gran numero di legami azoto-azoto, il composto è estremamente esplosivo e tossico.
Proprietà fisiche dell’azidoazide azide
Azidoazide under normal conditions (normal conditions) is red crystals with a density of 1.723 g / cm³, insoluble in water. The molecule is readily soluble in diethyl ether, acetone, as well as in some hydrocarbons, also chlorinated.
Thomas M. Klapötke (German Thomas M. Klapötke) and colleagues from the Ludwig Maximilian University (Munich, Germany) in their work on the preparation of 1-diazidocarbamoyl-5-azidotetrazole and the study of its properties stated:
“The [joint] sensitivity to impact and friction is no doubt in the range of 0.25 J for impact and 1 N in friction sensitivity, which can be determined experimentally. ”
Indeed, azidoazide is so sensitive that it will explode if it is easily touched by an object, moved a short distance (due to its sensitivity to friction), dispersed in a solution, and exposed to bright light.
Methods of obtaining
1-Diazidocarbamoyl-5-azidotetrazole can be obtained by diazotizing triaminoguanidinium chloride with sodium nitrite in ultradistilled water. Another example of the synthesis uses an exchange reaction between isocyanogen tetrabromide in acetone and an aqueous solution of sodium azide: this forms isocyanogenetraazide, the so-called “open” isomer, which quickly cyclizes under standard conditions to form a tetrazole ring and, therefore, a “closed type” azidoazide.
