Acetone Peroxide Answered

I've just been wondering, does anyone know if there is any way to stabalize acetone peroxide and make it at least a little "safer".

Discussions

Peroxyacetone is one of the reasons why the family business has hazardous waste disposal :P Part of the reason it's so dangerous is because of it's instability. Curious... why?

Questions like the one IlluminatedAntichrist worry me, should we invite questions that talk about explosives? 52 people and 4 bombers were killed a few years ago in London, about a mile from where I work...there have to be rules. Here is a quote from Wikipedia: "It is highly susceptible to heat, friction, and shock. For its instability, it has been called the "Mother of Satan".[1] It has perhaps sprung into notoriety due to its alleged use in the July 2005 London bombings and has also been reported as the explosive favored by suspects arrested on August 10, 2006 who allegedly intended to destroy airplanes flying from the United Kingdom to the United States.[2]"

should we invite questions that talk about explosives?

Absolutely! I truly feel that more fingers, arms, legs, eyes, lives etc. have been saved by not withholding information. Censorship can only claim responsibility for someone doing something he/she didn't know was irresponsible. Not telling someone the hazards etc. is not necessarily going to stop them from continuing.

With few exceptions; I'd rather explain how to do something safely (if I can), explain the dangers and/or explain where to get help rather than withholding that information. I'd rather protect someone and their bystanders from their own ignorance (weather or not they take the advice is another story).

In this case, I don't know much about it. I just know it's part of the reason my family's business has to treat it's waste as hazardous.... Heh, I forgot to mention where that waste is temporarily stored -- in heavy duty fire/explosion cabinets. That yellow thing is two of them -- but there's a stupid unfinished bed platform in the way :P


On the subject of terrorism. I also feel that if someone has decided that s/he is going to blow up a subway for whatever reason. They have made up their mind already. The information is out there, and if you've really made up your mind - you're already determined enough to find it. I just checked my school library's journal database for "acetone peroxide" - and got 83 hits (not all of them are full text though).

OK granted, I suppose I have a different outlook on this, but freedom of speech and all that. The compound is very unstable in normal conditions and this is why there was a failure during the second attempt on our underground system when the compounds failed. It appears that buying these chemicals is easier in the USA than in the UK[shrug]

I'm not quite sure what this is in reference to....


I'm curious though on what your thoughts are. Do you feel that withholding information you already have about this compound will prevent someone from attaining said information?

I mean no disrespect by that question (I can see how that could be taken the wrong way). I'm just curious as there's several "school's of thought" when it comes to dangerous substances.

I do not want to withhold information but I still have not got my head around the ethos of this site. I am a lecturer at a University and always ask students to self seek and ask if they do not understand. My role is to direct them in the right path (for that course), if they are interested in a particular subject I tell them by all means go learn but it will not benefit them om my course. My point is that this site invites a plethora of people of all ages, skills and knowledge. There are probably very few or no people who are experts in explosives apart from what they read themselves. I am just suggesting that if someone does feel like answering questions that are not in their field of expertise, they should say so and if they are not point them to a website that could be useful. I would prefer to get the person in the right direction. Every site has a purpose, I wouldn't come here to ask about SQL procedure writing just as I wouldn't expect someone to come to a programming site and ask about soldering. I just hope Instructables uses care when dealing with the original question and make a judgement call and say so and direct the person in another direction, you get more respect in doing this instead of getting the answer wrong and something goes awry,any way my two pence worth

Is that to say that the question asked is off limits then? With one exception, everyone that responded said they were unsure OR gave no advice on how to store this particular substance.

Also, is expert status required to answer a question? That is, if someone asked a question about building a loft or similar. Are those with a P.E. stamp the only ones allowed to answer? Personally, the best advice I've gotten was anecdotal from someone who may or may not have been an expert.


As far as ethos is concerned. I can't speak for the site -- but if I were to guess, it centers around DIY and open source. I'll bet if you posted an SQL question it would be welcomed but it would probably get a faster response (and more of them) on a forum with a limited scope.

I see that we are not going to see eye to eye on this discussion as you are taking a contrary stand point, my point about the SQL was if you want specific expert advice go to a website or research area which has that relevant knowledge base on that subject. If you just general advice, well of course come to a general site, I just don't think explosives should be discussed anecdotedly on Instructables and that was my point ,the person should be advised to seek it a second opinion on an site that has that knowledge. As you state "if I were to guess, it centers around DIY and open source" hmmmnn not explosives then :-)

Why not? -- those two things cover pretty much everything :P Open source can apply to any form of information :P

The way I read that is.... there's no project that should be discussed in the forum. Need building advice? Go to a construction forum. Need soldering information? Go to a electronics website. Need chemistry information? Find a chem. forum. Need to fix your bike? Bike forum. That would mean in theory, members of forums with a large scope have no purpose - but this is not the case in practice :P

I see that we are not going to see eye to eye on this discussion
Sure - I have enjoyed the discussion though :) And with that, I'll let you have the last word if you'd like ;)

No, no need :-) I have just published a new Instructable and I suppose I will get the usual negative comments :-( Anyway I will see how it goes.

In this case he obviously knows how dangerous it is, or would not be asking how to stablize it, which is a good sign that he wants to handle it. And does it help him to say how to potentially make a dangerous thing a little less dangerous, or to just discourage handling. Although I agree with not withholding information, I naturally see the side or a matter that is opposing the presented side...and just have to argue :D

And does it help him to say how to potentially make a dangerous thing a little less dangerous, or to just discourage handling.

How much does it help him if he (or she :P) just guesses how to handle the substance due to lack of information? Because you tell someone that they shouldn't be doing something does not mean that they won't - and if we're dealing with adolescence, not giving information may increase desire.

I too completely understand Jezza Bear's concerns (at least I think so). But as I mentioned, I truly believe that if someone has decided s/he is going to use this for evil, they will find a way - our withholding information isn't going to stop them. Because, after all, if we have something to share, we obviously got the information from somewhere :/

Starting from after I posted... I found a recipe and other useful information about the compound.

Storing acetone peroxide is not recommended, because it quickly sublimes. But if it must be stored, it is recommended that it is stored under water and in a container without a cap with threads, as opening it could result in an explosion from crystallized acetone peroxide.

Interestingly, this is not explosive - just highly unstable.

TATP and DADP neither detonate nor deflagrate; they are rare entropy explosions. The effect is from rapid dissociation of weak atomic bonds within the acetone peroxide molecules, not from a chemical reaction as seen in all common explosives.

So I wouldn't store this stuff... Of course, I wouldn't be synthesizing it either o.0

Using HCl as catalyst and and keeping the low temperature while the reaction will give you more stable AP keeping the AP more than few days will make it unstable. But still, this is an extremely dangerous stuff and I advise you not making it.

Water it down? I have no clue what acetone peroxide is, is it acetone and hydrogen peroxide mixed together?
