中文简介：

一瓶消毒用500mL 99%异丙醇（有效期至2007年），长期在水槽下方暗处久置。2019年5月，瓶子翻倒，盖子破裂，内容物流出，瓶主发现其气味比正常要弱，且蒸发速度也比正常情况下要慢。2019年11月，瓶主向水槽中倒掉了部分内容物，发现水槽中产生了气体(咋回事?)，并且在瓶底发现了约25g白色结晶。遂进行了X射线晶体学测试(？？！)，确认产生了TATP结晶。之后就是报警，被警方受控引爆。

原文：

On November 21, 2019, at approximately 2:00 AM, in Halifax, Nova Scotia, Halifax Regional Police carried out a controlled detonation of a bottle outside an apartment building.1 The bottle originally contained 500 mL of Life brand 99% isopropyl alcohol (rubbing alcohol, 2-propanol), with an expiry date of February 2007, and was stored in the dark underneath a bathroom sink. In August of 2017, and again in May 2019, application of the rubbing alcohol to sterilize an area of skin (on two different people) resulted in scab formation, thought originally to be a sensitivity to rubbing alcohol. Some time after May 2019, the bottle had tipped over, cracking the plastic top and partially spilling the contents, which were slower to volatilize than expected for pure rubbing alcohol, and whose odor was a little off. In mid-November, 2019, the owner partially discarded some of the remaining liquid, and at this time noticed gas evolution at the sink drain and the presence of approximately 25 g of a white solid mass remaining in the bottle. The owner initially thought that it might have been a result of product tampering, so a small sample of the solid was analyzed by X-ray crystallography2 and found to be a polymorph3 of triacetone triperoxide (TATP), an organic peroxide and high explosive. Once the solid compound was identified as such, emergency services were called to handle the disposal at the apartment building.

The ability of 2-propanol to form peroxides has been mentioned before.4 The exact nature of the solid peroxide formed has not been known until now. Stoichiometrically, 2- propanol and oxygen gas is equivalent to acetone and hydrogen peroxide, the ingredients required for classic TATP synthesis,5 which may be relevant to its formation under these conditions. Similar compounds are known to form upon photosensitization with benzophenone.6 Given the use of 2- propanol in clandestine drug laboratories and of TATP in recent terrorism incidents, the implications for police work are clear.
