How to Make Acetone Peroxide: A Primary High Explosive

A Primary High Explosive

Acetone peroxide is a primary high explosive. It is the product of the reaction between hydrogen peroxide and acetone and is an acid catalyst. It is notable for being a high explosive that does not contain nitrogen, but is very unstable and typically too dangerous for practical uses in an impure form. The oxidization that occurs when burning is:

2 C9H18O6 + 21 O2 --> 18 H2O + 18 CO2

These are some photos of the exothermic reaction:

Final Product

The video below is the final result, which shows 0.5 grams of acetone peroxide detonated in a metal container emerged in water.

  • I am not responsible for any damage or harm you cause!
  • This is a high explosive! Explosives are dangerous and illegal in many countries.

Editor's Note:

Out of respect to the victims of the Brussels bombing, this article has been edited to remove instructions on how to create Acetone Peroxide at home.


If you use an incandescent bulb to dry this it doesn't matter if you leave it unattended or not, if it is initiated there's nothing you will be able to do about it. Several people have died doing just that. Anyone who knows enough about explosives to safely use them would never use acetone peroxide. It is far too unstable for any safe use. You may use it repeatedly with no incident and believe you are safe, but without a doubt it will bite you in due time.

Further, you mention to 'scrape' the peroxide, not mentioning how incredibly sensitive it is to friction. There is also no mention of the variations to the molecule (diacetone vs triacetone) that are even more dangerous and are likely to result from just the slightest mistake in the introduction of the acid or the wrong reaction temperature. This is just enough information to get someone hurt. Please delete it.

Ok master Ben he will delete it You friggin nard, Freedom of speech freedom of expression, gee Ben You think You might be that one to try it? maybe give us all a breather from Your admin type attitudes... Japha if you dont know what japha is then if You do You know Your just a power hungry administrator lol go away ben, But in all seriousness the next article is goign to be how to commit suicide the proper way 'thus' succeding at it Your very first try... Later Days....

You are foolish if you think what I said violates of freedom of speech. Having the right to say whatever you please does not mean that all words are free of consequence. By your very own logic you yourself are in the wrong for denying my right to say whatever I please in previous comments. Further, regarding this article, you would be wise to listen to my previous warnings. They come from one who has made fireworks from the ground up for competition for more than a decade, and holds a federal explosives manufacturing license.

I gotta agree with Ben on that one, his warnings are accurate and well placed, Acetone Peroxide is very dangerous. I wrote this article for informational purposes only, because I found it fascinating how such simplistic, easy to purchase chemicals could form such a viscous explosive. We appreciate your input zZz, however, please word your comments in a less belligerent way in the future.

hi I just been looking at this piece on making exsplosives why doesn't some1 stop the people on the net from showing people how to make these dangerous exsplosive s no wonder theres many people making bombs I hope 1 day all this type rubbish is banned take care

As dangerous as it is, as bad as the end result would be - could be with some teen who has not yet faced his/her mortality and ends up blowing their hands off - I STILL would not infringe freedom of speech, of the press, etc. Gnawing away at those freedoms is precisely how the United States will end up like China where ALL information if filtered and monitored and the government controls every aspect of daily life. It's up to us (parents, aunts, uncles, grandparents, teachers) to lead, guide the younger generation on what to do with (or not to do with) the virtual overload of information now available on the internet and places like TOR. It's not the information that's dangerous - it's what we do with that information.

Really So what you didn't look all this stuff or did you? I mean so what only you should be able to look all this rubbish up your highness? Is that the jest here? I don't get it you answered your own fucking question and bitched about it. But you were able to look it up. Kinda like I wanted to do just like you you fucking NAZI!!!

It's important to allow freedom to say what one wants to say banning such speech from the Internet would infringe on the rights of others. Any banning of speech is an insult on Americans and on their rights as Americans. I agree this material is dangerous to make and one should never do so, but it's my right to be able to read and learn how to do it if I ever need it in some unforeseen future.

I agree, acetone peroxide is an extremely dangerous explosive. First, by refrigerating the initial reaction between the acetone and the hydrogen peroxide, you are creating the "trimmer" which is the second molecule variation you mentioned. This is relatively safe to handle, and will not go off at the touch. Second, this article is for informational and demonstration purposes only. NOT to be attempted. Thirdly, the reaction between the specified amount of ingredients will only make a small amount of acetone peroxide, not enough to cause serious damage in the process. However, when placed in a confined space, it is extremely dangerous.

Regardless, thank you for the tip, i have added in the information about molecular variations, and also provided more warnings of the volatility of acetone peroxide.

Yea so - I'm all for sharing information, but this seems like its going to get me added to some watch list for something.

People are obviously going to see the listed ingredients, and seeing as there are steps and advice on how to make it, I don't think you can really claim its for "demonstration" only.

Seems very dangerous...

You probably are already on a watch list that scary self photo.

I get goose bumps thinking your running around loose without an ankle bracelet. UNLESS you already have one on and have figured out out to hack its transmitter OMFG you need to be stopped!!!


There are much less dangerous experiments that involve fire by exothermic reaction that don't involve bodily harm. Try Potassium permanganate and (if possible) water free glycerine. It will react a minute later with a small sizzle and a flame and won't explode. For special effects you can also mix the permanganate with hydrogen peroxide. It will result in a boiling geyser with lots of vapour. Stay away from mixing hydrogen peroxide with so highly inflammable stuff as acetone. All the chemists around me (myself included) would stay away from high explosives for good reason. There's a joke amongst us: How do you recognise a chemist dabbling with high explosives in his garage? You can't shake hands with him.

haha, nice. yes, high explosives are dangerous. still, the concept is important to chemistry, without it we would not have combustion engine or firearms, and any number of things we take for granted.

About four years ago I experimented with AP and the way it responds under different circumstances. When igniting small "pea size" amount (on 1/2 in thick sheet of plywood) I got small plume of fire. "Dime size" amount, even larger plume.
When I got up to 3 grams or "quarter" size amount it imploded making a large Bang that rang my ears for about ten min and put a hole through the plywood... Just a thought to all you people who think it's cool to ignite it in your hand...

For the record, I used food grade H2O2 and concentrated H2SO4 as the catalyst ..and needless to say I don't mess with the stuff anymore.. And although I hate that the info is available I'll fight to the death for your right to post it.

could this be used for some type of squib for movies perhaps?

"Squib" is used in display pyrotechnics.

ah! well, i suppose it could work, but it wouldnt be the best choice. something like flashpowder or similar oxidiser-metal-sensitizer would work better :)

Not saying that I would use it. In mining a squib is also referred to as a "slow match", which definitely takes acetone peroxide out of the picture. I used to experiment with the picrates until a shock-sensitive compound exploded prematurely.

We blow things up that are more explosive than this in my University's chemistry lab all the time! The author gave clear instructions and described precisely what was being made in simple scientific terms. I think you could learn a lot from this and support it remaining on this site. Knowledge is power and power can be used for good or for bad, it's all in the person. Someone could indeed get hurt from this, but you risk dying in a car accident every day. It should be up to the person what sorts of risks they want or do not want to take. That is my opinion anyhow...Great article, I look forward to future posts.

Thank you! :) Ive always loved chemistry, i never get tired of how amazing it is to take two ordinary, boring substances and turn them into something furiously powerful.

So if anybody even reads this. are they considered a Terrorist or are they just someone surfin the net 4 survival? I mean I saved my lunch money ,I think for my 1st chemistry set,thx 2 mum. :(

You're only a terrorist if you use your knowledge to blow people up otherwise you are just a crazy scientist who likes to learn and watch super-awesome chemical reactions!? :)

and there you have it, someone with a sense of humor instead of a worry wart, hey if some insane dewderz is going to mix this concoction up and kill the masses it will be on the eleven oclock news let the author of the well explained article be at peace geez already, a grain of salt not an atomic bomb of worry wart juice over us all LOL and so it goes...

I store both strong peroxide and acetone in my kitchen for cleaning. Can anybody tell me wther it is dangerous to mix these two products? Never knew how dangerous these chemicals are.

Though I do suggest that you do not store oxidizers and fuels (acetone) together, in this case there is no explosive harm. This is a process not a mix, so there needs to be a chemical reaction, initiated by the acid, to form the explosive.

Some fuels and oxidizers need only be mixed an can create an explosive so be very careful. Also if you are talking about walmart peroxide, which is like 3% strength then you need not worry, they are talking about concentrated peroxide.

Can't we add some glue too solidify the substances?
That way we can handle the acetone peroxide more carefully!!!

So this is labeled a "high explosive". Does this mean that if you were to go against the advisement suggested in the articles above and experiment using your chemical synthesis you could accidentally blow up your house? I mean, also assuming you use a much larger quantity of the ingredients listed. I am only asking out of curiosity, I value my limbs and my home so I don't think I would want to experiment with this as my first try at explosives. I have just been watching movies for years now and I'm curious how they build all these bombs they use to blow up everything from a person to a city block.

Acetone peroxide is NOT a high explosive... it is a primary explosive, and one of the most notoriously dangerous. It is more powerful than most high explosives and, most importantly, very sensitive... it is used in blasting caps to set off larger charges. Legality aside, I suggest you move on to a another chemistry project. Believe me, this is the stuff that eviscerates hands-- it's worse than degloving. And if you choose not to, don't follow this, use Megalomania's method... the site was shut down a while ago, but it's still archived at MIT. Just google "Megalomania's method" and all the syntheses will come up. Whatever you do, don't make this. Even HMTD is safer...

I made this stuff back in 1999 . at first i was having lots of fun .that's when the crap hit the fan .4/6/1999 at 12:20 a medicine bottle 1" x 3" blue up after putting it in in the frig when i shut the door . i all most blow off my right leg .that night i died .they forced in 7 units of blood and 3 units of plasma . the police claims they felt and heard the blast 3 1/2 miles away . I used 2 parts of one ,1 part of the other , and 10 drops fuming sulfuric . u have to do it right or it blows while it is a liquid .

I have mixed acetone and peroxide 40% together i had no problem very flammable thats all ...... but even the after the crystals are taken out of the actual mixture , the mixture is an explosive so watch out .the sun light will set the powder off .i set some down ,went to get another container ,i got about 50" it blow . VOICE OF EXPERIENCE !!!!

I know this post is years old but I still wanted to point this out, AP IS a high explosive, primary, secondary and tertiary are considered sub-categories of high explosive. The definition of a high explosive is any material that will can detonate explosively by itself without confinement, a low explosive will only achieve deflagration e.g Black Powder unless under confined circumstances.

Chemicals are tools, just like firearms and other dangerous things.
They are neither good or bad, but depend on the user to determine if they are going to do good or bad with them.
I thank you for expanding my knowledge!

These ingredients aren't something that TSA checks for going onto flights. Would it ignite from the change in pressure during a flight?

I have no idea whether a change in pressure will do it. In general any force or energy can cause detonation of an explosive; the more unstable the more likely a small disturbance equals disaster. While TAP, a nitrogen-free compound, doesn't register on nitrate-testing equipment, airport security will investigate any non-standard container holding an unconsolidated powder when it sees this on X-ray scans. It is even possible that the TSA has begun spot-testing for chlorates and organic peroxides by now as weaknesses in chemical detection have become more apparent. They aren't in the habit of telling the public what they look for, and make frequent changes in procedures in accordance with the latest intelligence information. Expense and time mean that only luggage of suspicious source or unusual appearance on X-ray undergoes additional screens for explosives. Airlines will not fly unaccompanied bags, however, to ensure that a bomb on a plane is a suicide mission for any takers.

Meanwhile, the word "trimer," referring to a molecule composed of three repeats of a basic chemical unit, was misspelled in the article. I'm not sure a reliable recipe of this nature can be crowdsourced; one simply must get professional advice on explosives before attempting to make them, a step I'm sure our friendly terrorists never omit. But the article's photos do suggest a combination of chemical containers which, if you see them together in one place, may indicate suspicious activity.

I don't want to burst any bubbles but it could be a major piece of a recipe that could save some body parts. In your initial post on how mentioned Murat acid and said that it is simply Hydrochloric acid, however I fear you made a mistake. Muratic acid is composed of SULPHERATC acid used for etching concrete. HYDROCHLORIC acid is what is put in car batteries. I don't know that it would make any difference but it might be advisable to amend your recipe at the top of this blog.

You have it backwards. Hydrochloric is "muriatic" and used for etching concrete. Sulfuric acid is what is put into car batteries.







No matter how dangerous something can be if handled the wrong way, information must not be withheld. There are good and there are evil in this world. If the good people don't discuss how stuff like this is made and the proper way for it to be handled, who is going to stop the bad people from passing the information; that likely will be incorrect or lacking important safety precautions that may be detrimental to others. Someone who is curious to try something like this is going to get the information on how to do it in one way or another. Why pass up the opportunity to educate people on the proper way of doing it? Just like gun control only hurts the good guys who follow the law, no one should be restricted access.

Use Ammonium nitrate instead of APEX. Nobody needs APEX...

thanks to your naivety in posting this recipe, disaffected people blew up Brussels airport early this week...

It's time to take this site and similar sites down. Home grown terrorists; crazy kids with mayhem on their minds and rogue religious fanatics wander the internet in search of this information. Obviously, anyone with a chemistry background might have this information; but, for many people (like me), who have little or no knowledge, this site is a recipe for bomb making. (I happened upon it while looking up information about installing a deck). The author would be devastated to learn that this site was used to kill innocent people. I urge the site owners to remove this information and similar sites immediately. They should not contribute to the mayhem and disaster that is so obviously accelerating in the western world. Paris, Brussels, San Bernardino.....

P.S. I am thinking about forwarding this site to the local authorities and having them ask you to take this information off the internet. If you can't appreciate common sense; perhaps the local authorities can persuade you.

Also, if anyone dies due to this information, don't be surprised if you get sued.


I get it, and you are right, but not entirely, because it is actually a very safe explosive, as long as you do not blow your hands off. The main detonationproducts are Acetone and Ozone, and remember this explosive comes in at 5300 m/s, which is adecent seondary charge, onthe high end TNT comes in at 6900 m/s. True it is volatile, no do not put it in your clothing, very strict rules and guidelines are necessary and people with the innate discipline to handle such substances always in the same predictable manner. The point is this detonation does not what most others will do, this detonation is the restructuring of mocecules going from a solid to to a number of different gases. Yet these gasses are not an end stage, I would say that I might expect such gases in the factory where they made the explosive, not as the residu of the detonation. The substance can easily be made safer Wikipedia :

Shock sensitivity High / moderate when wet
Friction sensitivity High / moderate when wet

There is hardly any heat produced, no fire, the entire punch of 5300 m/s seems to be in the expansion of the Solid turning to Gas, there is no heat to speak of causing additional expansion. There will sooner or later be an environment where people work in which this 'fireless and cold explosion' is desired, even when it is volatile, for instance area where dust explosions are common, usually triggered by static electricity, fire, sparks and such this detonation even keeps acetone and Ozone stable. Environments withnatural bituminous coal and thus a volatile atmosphere, might benefit from such 'weird yet intrigueing' explosions taking place in only a small part of the energy spectrum, in this case rather kinetic.

It struck me, that the reaction taking place may be a reducing reaction, if it had been an oxidationreaction,there would be no Ozone or Acetone. Anyone any good in REDOX-reactions for a better educated answer thanmine?

Greetings Johan

A few more things, and a good reason for the author to start playing again, below 2 grams the explosion is classified as a pyrotechnical explosion and not a detonation for Acetone Peroxide.

I forgot to say that there is another reason it is 'safe', it has no need for all sorts of add-ons, to go from initiation, to a complete explosion, since more parts also makes for more things to go wrong and the most dangerous explosives are those which were triggered but remained without reaction. At no time one can say it is safe now, whether the canon of a tank must be unloaded (2 hours inactivity, the body is made of cardboard only the bottom, which is ejected after the projectile left the nozzle is metal), Or when one has to detonate a hand-grenade which failed to detonate, it is at no time safe and having an ambulance close is certainly no misplaced luxury

One should always feel entrusted with explosives, yet never trust them..
