The explosion of trimeric acetone peroxide was probably caused by the combined effect of static energy and friction. The static energy accumulated in man can be 30 mJ. We performed different sensitivity tests with the isolated substance. It exploded moist with an 11.5-mJ electric spark. In impact sensitivity tests, it ignited repeatedly with a weight of 2 kg from 10 cm's height. In friction sensitivity tests, the sample ignited with a weight of 0.5 kg. The ignition sensitivity increased when the substance was dried.
"Acetone peroxide" most commonly refers to the TCAP (tri-cyclic acetone peroxide, or tri-cyclo, 9186) obtained by a reaction between and inan acid- . The (C6H12O4) and open are also formed, butunder proper conditions the cyclic trimer is the primary product. A form was alsodescribed. In mildly or neutral conditions, the reaction is muchslower and produces more than the reactionwith a strong acid catalyst. Due to significant of the inthe dimer and especially the monomer, they are even more unstablethan the trimer.
Triacetone triperoxide (TATP) is a highly unstable explosive prone to unintended detonation. Yet terrorists, such as those responsible for last week’s bombings in Brussels and the November 2015 attacks in Paris, are increasingly using the compound to inflict carnage.
While making 6-amino-penicillanic acid-oxide, there was an explosion in our laboratory, at which time one man was injured.. The cause of the accident has been found to be trimeric acetone peroxide.
Acetone peroxide (triacetonetriperoxide, peroxyacetone,TATP, TCAP) is an and a . It takes the form of awhite crystalline powder with a distinctive acrid odor.
But the white crystals, also known as acetone peroxide, triacetone triperoxide, or TATP, continue to lure terrorists with the promise of a powerful explosive whose ingredients are available at local stores, whose recipe can be found on the Internet within seconds and whose components are easier to assemble than the concoctions in most cookbooks.
It is certainly not easy to get higher volume peroxide solutions in the UK now, even though they were routinely used by hairdressers. Restrictions were introduced after some terrorists used the local woods as their base to prepare some TATP (and somehow didn’t blow themselves up) .
I wonder how many people have risked this same inadvertent synthesis by washing out a NoChromix cleaning solution (which to my knowledge contains an oxidizing peroxide) with acetone to try and dry it faster….
Wow thanks–very good lesson for students. Given how common these chemicals are in labs (acetone and peroxides of various kinds), its amazing that this does not happen more often.
After the bombings in London on 7/7/2005 I remember reading that the terrorists had bought large quantities of dilute hydrogen peroxide, and had concentrated it by boiling it down.
the stabilized 3% H202 in your medicine cabinet’s probably not an explosion hazard. Don’t know why you’d be chasing it with nail polish remover (the acetone most folks have right next to the peroxide in the medicine cabinet). Acetone does a decent job dissolving some things that might be clogging up your drain, but strong bases will turn them into a nice, soluble soap.
Similar thing happened in our lab… a glass frit was cleaned with Caro’s acid (Peroxymonosulfuric acid, H2SO5)… after the Caro’s acid went through the frit, the absent-minded chemist squirted a dash of acetone into the frit to accelerate the drying process… big mistake… boom
15 vol H2O2 solution is apparently OK, and 2-4+ grams of TATP are considered likely to explode uninvited. The trimer, made by keeping the reaction below 10C is slightly more stable than the dimer. However most forms are not pure, and not stable on storage. Full manufacturing details are widely available, but pre-experiment risk assessments are not included or prevalent.
Therefore, a capillary isotachophoretic method was developed for determination of residual anions (originating from the acid used during TATP synthesis) in the resulting TATP crystals.
Acetone peroxide can also occur accidentally, when suitablechemicals are mixed together, for example when is mixed with acetone while making fiberglasscomposites, and left to stand for some time, or when a mixture ofperoxide and hydrochloric acid from etching is mixed with waste acetone from cleaningthe finished board and allowed to stand. While amounts obtainedthis way are typically much smaller than from intentionalproduction, they are also less pure and prepared without cooling,and hence very unstable.
