Decomposition of HMTD (after 17 Months of Storage)
Разложение HMTD (после 17 месяцев хранения)
After experiments with explosive rivets, a small amount of HMTD (hexamethylene triperoxide diamine) remained. By the time the experiments were completed, the substance had already been stored for a year. The safest course of action was to dispose of the HMTD immediately, as organic peroxides are hazardous during storage. No further experiments with this substance were planned.

However, I was curious whether the compound would undergo decomposition during prolonged storage. Therefore, I postponed disposal of the peroxide until spring, assuming that an unexpected ignition was unlikely in a cold and damp laboratory.

Seventeen months had passed since the synthesis of the compound. The HMTD sample had a strong odor of hexamine, whereas in the case of freshly synthesized compound this odor was practically undetectable.

I weighed out 0.05 g of HMTD, placed it on a piece of paper, and touched it with a smoldering splint. A yellow flash occurred, accompanied by a characteristic sound, and white smoke formed. The odor of hexamine was noticeable. After the flash, the paper remained unchanged.

During the flash, relatively large solid particles were ejected in all directions, leaving visible trails of smoke. This effect was not observed during the flash or explosion of a fresh sample of HMTD.

I then spread the remaining substance (2.2 g) onto a sheet of paper and ignited it with a splint. A large yellow flash occurred, accompanied by a loud sound, and a significant amount of white smoke was produced. Tiny brown spots appeared on the paper. As in the previous experiment, numerous relatively large particles were observed, leaving trails of white smoke. A strong odor of hexamine was again noticeable.

Thus, after 17 months of storage in a plastic cup, the HMTD sample exhibited clear signs of partial decomposition.



Разложение HMTD (после 17 месяцев хранения)
После экспериментов с взрывными заклепками у меня осталось небольшое количество HMTD (гексаметилентрипероксиддиамин, ГМТД). К моменту окончания экспериментов вещество хранилось уже год. Самым безопасным вариантом было утилизировать HMTD немедленно, поскольку органические пероксиды представляют опасность при хранении. Дальнейших экспериментов с данным веществом не планировалось.

Однако мне было любопытно, разложится ли данное соединение при дальнейшем хранении? Поэтому я отложил утилизацию пероксида до весны, решив, что в холодной и сырой лаборатории вряд ли произойдет неожиданное его воспламенение.

Прошло 17 месяцев с момента синтеза. Образец HMTD сильно пах уротропином. В случае свежесинтезированного вещества запах уротропина практически не ощущался.

Взвесил 0.05 г HMTD, поместил его на лист бумаги и прикоснулся к веществу тлеющей лучинкой. Произошла желтая вспышка, сопровождаемая характерным звуком. Образовался белый дым. Ощущался запах уротропина. После вспышки бумага осталась без изменений.

Во время вспышки во все стороны разлетелись сравнительно крупные твердые частицы, которые оставляли после себя шлейфы дыма. В случае вспышки или взрыва свежего образца HMTD такого эффекта не наблюдалось.

Оставшееся вещество (2.2 г) также насыпал на лист бумаги и поджег лучинкой. Произошла большая желтая вспышка, которая сопровождалась громким звуком. Образовалось много белого дыма. На бумаге появились крохотные коричневые пятна. Как и в предыдущем случае, наблюдалось много сравнительно крупных частиц, которые оставляли после себя шлейфы белого дыма. Ощущался сильный запах уротропина.

Таким образом, после хранения HMTD в пластиковом стакане на протяжении 17 месяцев наблюдаются признаки частичного разложения вещества.
