Furthermore formaldehyde is a bit acidic (pH around 4) and Hexamine will decompose under acidic condition so by adding excess ammonia we can assume that the solution will be basic (pH higher than 7) which prevent decomposition of Hexamine.

I'm sure that you realize this at this point, but your stoich is wrong. Because formaldehyde (30g/mol) and ammonia (~17g/mol) have different molecular weights, you cannot simply use a direct mass ratio like this.
I have heard of this method, but have never seen a demonstration (I'd love to, though). I'm guessing, as I do not possess any formal chemistry background or training, that the methanol is heated so that the vapors pass over the heated catalyst to a cooled receiving flask. Am I mistaken, in any respects?
any of you brothers know the ingredients and ratio to make a 50x50x50cm cube (125 litres) of clear as possible silicone? Or an equivalent material where it will set solid, but not brittle. I was thinking silicone or rubber, there will also be a small object suspended in the middle. Hope you can help, thank you
Feynman I believe I saw where mold casters put the poured silicone under vacuum to clear out the bubbles...if your object is air filled that may cause much distortion. Good luck
I followed the recipe only I subbed muriatic acid for formaldehyde. how can muriatic acid be a weak Hydrochloric when it smokes and Hydrochloric doesn't?
First of all, muriatic is relatively strong, but not super strong as hydrochloric acid gets way more concentrated. iirc muriatic is usually around 30%. Secondly, you can't substitute HCl for formaldehyde, they are different compounds. You have to use formaldehyde.
Justin Hiemstra If you want to know how to make it yourself: Take paraformaldehyde or also knows as paraform (it's a polymer wich comes in prills and is used as an Disinfectant). When you heat it up it will depolymerise and you can lead the Formaldehyde gases directly into your ammonia. But do it outside since formaldehyde isn't that healthy.

Just an FYI but if you have 4 grams of NH3 and 6 grams of formaldehyde the MOLAR RATIO IS not 4 to 6. The MASS RATIO is 4 to 6............................Four grams of NH4 is .235 moles OR 23.5% of a mole. So if you multiply the the molar mass of formaldehyde (30 g/mole) times .235 you get a 1 to 1 molar ratio. So 30 X .235 = 7.05.....................Then multiply that by 1.5 because 6 is 1.5 times bigger than 4. So 7.05 X 1.5 = 10.575. SO if you want a MOLAR ratio of 4 to 6 then you need 4 grams of ammonia and 10.575 grams of formaldehyde
It may be possible since Formic acid and formaldehyde are very similar, you might have to change the ratios though. If you do from what I have heard it’s good to have an excess of ammonia since hexamine can dissolve in acidic solutions, and formaldehyde and obviously formic acid are, well acidic. So by having an excess of ammonia that should provent to it.
Why does everyone in this thread think chemistry works like baking, and you can just substitute one thing for another and it works like magic? You would have to know a lot chemistry to make such a substitution, and even then it would have to be confirmed by experiment. Since there are literally billions of unique small molecules, just guessing at one giving the same reaction is going to be pretty unsuccessful.
Well you would catalyze methanol at around 600 c..... methanol in, methanal (formaldehyde) out.... Keep looking there is lots of info on this... I dont think you will be able to do it at home. there are only a few manufactures for the whole worlds supply. but that is how it is done.
Most formaldehyde comes with some methanol added as a stabilizer... Which forms nasty stuff when mixed with ammonia. Might wanna keep that out of the environment, eh?
Can't seem to find the answer online and I know you can help. Doing this process in reverse (Hexamine+HCl) makes Ammonia and formaldehyde. Is this in the form of a liquid or gas? Where did you get your formaldehyde? I just need the formaldehyde for preserving things.
You will not be able to separate the two, they are both miscible in water. the temperature is very important too, I would suggest you go to ebay and just buy formaldehyde.
Jaybird196 get 16AWG or bigger solid copper and coil it like cin. roll and heat to a cherry red, and then hang it over the methanol, just like what he did from one of his experiments. then set up for condenser. just look it up online to make sure you got the vol/mass right
If you want to make an explosive peroxide, just mix acetone and 30% hydrogen peroxide. Just remember that it's a powerful explosive (high explosive) only in the dry compressed (maximum density) state. Now it just needs to sense a little heat and it will explode with a loud bang at 5300m/s.
Wow never knew that TheBackyardScientist did videos like this! Stumbled upon this while looking for a hexamine synth and it's pretty cool to see.
Its so jarring but, so 2010 YT so its great

Using stochiometry you should mix 68g ammonia with 180g of formaldehyde.
now show us how to nitrate it
Prolly just like nitrating anything else. nitric and sulfuric acid mixture.
@@jonross377 I guess dil HNO3 works best here, else it'll get oxidised
Can you refine the hexamine somehow into a purer form?
That was pretty pure bud.
No, clearly it wasn't pure.
10g in 100g of solution not water. There's 90g of water. How do you get that wrong?
but is RDX explosive or do you have to at another base like PETN or TNT
You need another high explosive to detonate RDX. It's necessary high temperature and fast shockwave.

Nitrogen is incredibly difficult to oxidize, so probably not. Even when burning ammonia, you will not make nitrogen oxides.
