Making RDX based Platic Explosives
I don't take any responsibility written, spoken, or implied in any way for what anyone does with this info. Making any explosives is dangerous and illegal. I suggest further reading for understanding the chemistry, handling, and legal use of explosives.
Ok guys so many are asking how to make something. Though I am a fan of using premade explosives for safety reasons, I'm posting this due to so many repeated questions.
You will need Hexamine, nitric acid, sulfuric acid, ice, salt,distilled water, Baking soda.
Hexamine. Hexamine can be obtained in three manners. 1. From a chem supply 2. From Hexamine Fuel tablets found at surplus stores, camping stores, and gun shows 3. It can be easily synthesized.
If fuel tablets are bought you don't have pure hexamine. You have hexamine mixed with parraffin. To separate it out crush the wax and mix the "powder" with acetone diluted with 35% by weight alcohol. This will remove the hexamine. Filter out the solution and evaporate the remaining liquid, the white solid remaining is hexamine.
Hexamine is easily synthesized. It's a simple process of mixing Spirits of Ammonia, household clear cloudless unscented Ammonia, with formaldahyde. Formaldahyde can be purchased at some pharmacies or ordered from pharmacies or chem suppliers. The reaction is: 4 NH3(aq) + 6HCHO ---> (CH2)6N4 + 6H20 Evaporate the liquid to get the solid hexamine.
Now the hard part, trinitration of hexamine.
The nitric acid should be of the red fuming variety, the sulfuric acid should be white fuming.
Place a quar jar in an ice bath, a mixture of ice, salt, and just enough wate to make the ice float and have water between each cube. Weigh out 300g of Nitric acid and 90g of Sulfuric acid. Place the Nitric acid in the jar first and let it cool to under 30�F. Now slowly add the Sulfuric acid, about 30g at a time. After each addition mix the solution and allow it to cool. We now have what is called mixed acid, probably the most vital ingredient to explosive manufacturing.
Now pour off the solution into 3 separate containers, 130g each. Chill one container to under 30�F. To this add 55.73g of hexamine.
This is the reaction in whole: 6HN03.H2SO4+2(CH2)6N4-->2(CH2)6N4(NO3)3+3H2 +H2SO4
The sulufuric acid acts as a catalyst, hence it is not used up.
Add the hexamine around 10-11g at a time, stir the mixture slowly, it will start to warm up, as it does allow it cool and stir again. White crystals will start to appear. Filter these out and add to the second container of acid and repeat the mixing. Do this again with ther third container of acid.
After the final filtering wash the crystals with a dilute mixture of baking soda and distilled water, then again with just distilled water. You now have fresh RDX Crystals. These are heat and friction sensitive.
To use them add them to a 1/2 as much by volume Petroleum Jelly. This makes the explosive more stable and safer to handle, a cap is needed for detonation.
There you have it folks.

Re: Making RDX based Platic Explosives
Like I said research pays off, don't use the above formula it won't work, the numbers are wrong.

Re: Making RDX based Platic Explosives
people read it skbitch, no one here is smart enough to question. Which is why comments like you're are made, out of ignorance. When your reaches more than that of a severely mentally handicapped sack of shit, maybe your replies will actually mean something to me. Until then, go to hell.

I may not have read the whole posting, but I greatly appreciate shit like this. People put time and energy into spreading information and teaching.
So yeah, Sck, go to hell

Re: Making RDX based Platic Explosives
Proper recipe.
You will need Hexamine, as made in the earlier post or boughten. The mixed acid as mentioned, the ice bath, a thermometer.
Reaction is as follows:
C6H12N4 + 2 HNO3.H2SO4 ---> C3H6N6O6 + C3H6
Hexamine plus 2M Mixed acid yields RDX crystals and cyclopropane. Neutralize the solution with baking soda and the RDX will precipitate out. Filter wash and store yet.

Re: Making RDX based Platic Explosives
Hi, I've read your previous post, and it's not going to work... at least part of it. I tried the formaldehyde / NH3 reaction 2 or 3 years ago, in order to make RDX, and it didn't seem to work.I didn't find hexamine, you know. You probably need some catalyst and quite particular conditions for the hexamine to form. I probably got something like HCHO + NH3(aq)--> H2COH-NH --> H2C=NH+ H20. Anyway, I didn't know that until the nitration. Nitration should have worked, that's why i know the hexamine had not formed. After the useless nitration I had no crystals, all I had was a clear solution, a bit dense, smelling like hell (i mean strong, it'd burn your nose, and it wasn't the acids). I couldn't crystalize anything(well, i didn't try very hard, either). It should be some sort of weird nitrocompound of methylimine, probably a liquid. --- The problem with your post is that your reactions are like shit. People here must be laughing their ass off! Now, seriously, you need three nitro groups for each hexamine molecule so that you get cyclotrimethyleneTRInitramine(RDX). this is rdx: (i hope the web doesn't screw up my nice ascii art )
NO2 | N / \ | | N N / \ / \ O2N \/ NO2
-CH2-NNO2-CH2-NNO2-CH2-NNO2-
Maybe you want to add more acid in order to get more product, so that all HMT reacts, but that's another story. It's extremely unlikely that cyclopropane forms. It won't form the way you 'guessed', anyway. Also, it's likely that the reaction has several steps. Oh, and making RDX isn't a matter of 'mixing things', you need a method that works; temperature and concentration are probably things to watch for this reaction. I haven't read any patents or 'official' synthesis for RDX, and it's difficult to know what goes on in such a reaction without documentation. This stuff isn't as simple as nitroglycerine or TNT. Anyway, there are a some files on the internet which actually follow a method for the production of RDX. Some tell you to do something, some tell you not to do it... In the end I don't know which one is right. There are just about 4 or 5 methods on the net, all the others are just copies based on these 4. I have a lot of such files. I haven't seen the docs here in the new HTMLized &totse, but there must be something. You should start trying some of these methods, if you have the hexamine and the acids and some basic 'equipment'. They just say 'use 10g hexamine', 'heat the mixture to 55�C' and things like that. Simple, huh?

Re: Making RDX based Platic Explosives
Napalm,
My reaction is balanced and it does work fine. Heat or refluxing is not needed the acids are reactive enough, sulfuric acid being a catalyst as well. You mostly likely used formalin and not formaldehyde, people have done that in the past and probably still do it, mistaking it for formaldehyde. The chemical reaction for making hexamine I posted is an industry standard per DuPont and others.
The whole deal has been researched and used, it works. Do you happen to live in the OH area? I could show you, ya know.

Re: Making RDX based Platic Explosives
Of course hexamine is produced that way. I probably did something wrong but I had lab grade reagents at that time, and formaldehyde is formaldehyde, I'm not making silly mistakes. The hmt->rdx reaction is wrong. Well, you could just mix hmt, hno3, h2so4 and still get some rdx, but you'll need 3 moles of acid per mole of HMT at least. And cyclopropane won't form. Or you could tell me why it would form. And why you're using just 2 moles of acid per mole HMT.

Re: Making RDX based Platic Explosives
ooh shit my bad. Yeah you're right typo on my part. It should be 1.5L of 2M Mixed acid.

they're detonated with blasting caps, there are numerous kinds of blasting caps that are set off by different means.

Re: Making RDX based Platic Explosives
Most RDX produced industrialy uses the K process using paraformaldahyde,acetic anhyride, and amonium nitrate.
