like the stuff muslims do

nah british cooks use phosphorOUS h3po3 acid and heat from the RAYS OF THE SUN and concave specially designed flasks that concentrate the beams of the sun to boil the solution, real green organic meth ya innit
we already had this threadFormation of Hexamine
For weeks I've been trying to figure out a way around the formation of Hexamine (C6H12N4). It's used as a solid fuel tablet for cooking.
From some websites I found some tiring way to prepare it: Hexamine is made up of Formaldehyde (CH2O) and ammonia. Ammonia is relatively easy to obtain, except for the Formaldehyde. Here's a method for Formaldehyde I found on Wikipedia: "Industrially, formaldehyde is produced by the catalytic oxidation of methanol. The most common catalysts are silver metal or a mixture of an iron oxide with molybdenum and vanadium. In the more commonly used FORMOX® process methanol and oxygen react at ca 250-400 °C in presence of iron oxide in combination with molybdenium and/or vanadium to produce formaldehyde according to the chemical equation
2 CH3OH + O2 → 2 H2CO + 2 H2O
The silver-based catalyst is usually operated at a higher temperature, about 650 °C. On it, two chemical reactions simultaneously produce formaldehyde: the one shown above, and the dehydrogenation reaction
CH3OH → H2CO + H2
Formaldehyde is readily oxidized by atmospheric oxygen to form formic acid. Formic acid is found in ppm levels in commercial formaldehyde." Too complicated and difficult!
Is there another easier way to figure this out?
Just my advice, son, but unless you are fond of the rotan I would not get caught in Singapore making or acquiring the basic raw material for preparation of RDX and HMX.
I would be very surprised if its sale and manufacture are not proscribed without a special license in Singapore.
Naturally you could try to convince the authorities that you needed hexamine aka hexamethylenetetramine aka Urotropine as a urinary tract disinfectant. Good luck with that defense.
The tedious part about the prep of hexamine is that both formaldehyde and ammonia are employed in their aqueous solutions and all that water needs to then be evaporated off after the condensation of 6 mols formaldehyde and four mols ammonia. As if you didn't have enough water to get rid of, the condensation itself produces more water.
My advice is, stick to a peper chase on energetic materials or move to a freer country. In Sg, even a paper chase can land you in hot water these days.
As a former highly paid consultant to Singapore's MOD, I am familiar with their methods. Changi is a nice airport but a nasty prison. -
2024-08-06 at 2:51 PM UTCI knew it was some sort of explosive.
To be honest It was the first thing I was thinking about this morning and instead of googling it I thought I would ask my favourite reprobates. -
2024-08-06 at 3:12 PM UTCRemember that scene of breaking bad where Walter White steals and entire drum of Methylamine? turns out he's a fucking idiot
Methylamine Hydrochloride from HMTA, Eleusis' version [with comments by Rhodium]
140g of Hexamine is carefully dissolved in 400mL of Muriatic Acid (31.45% HCl) to which at least 100mL of (preferably) absolute ethanol has been added. Add the hexamine slowly while stirring vigorously and with good ventilation as some nasty fumes are produced. Allow all to stir at room temperature for at least 8 hours but preferably 16. The solution will become turbid within several hours of the initial mixing. I *believe* this is the formation of a formaldehyde trimer of some sort and I suspect that the original equation for the conversion of hexamine into methylamine fragments is therefore incorrect. [There is no trimer of any sort formed, if enough water and formaldehyde is present. Eleusis uses 4 moles of amine to 6 methylenes, which is enough, but gives less yield.] At any rate, enhancement off this white precipitate which is obviously not an amine salt due to it being fluffy even in Florida's humidity (almost all simple amine salts are hygroscopic) [With the exception of ammonium chloride, and this is it]. Finally, remove the excess water, hydrochloric acid and freako volatile products by, ideally, heating the liquid at low to medium heat in a porcelain saucepan. Stove-proof glass would be ideal, but stainless-steel, aluminum and copper are definitely not! [Rather use a RB flask, with a water aspirator attached, smells considerably less]. The concentration can generally be left unattended for a couple of hours, but try to stick around and babysit it at least the first time so you will have a good idea of how long it takes for your particular stove/pots/etc… [Or else it'll BURN!] Also, the methylamine HCl will form a melt if heated too long at which point it will sublimate off. It will then appear as if it's taking forever for the stuff to concentrate when in fact you are merely boiling your product away. After the concentrated slush has become sufficiently "thick", take it off the heat every so often to see if it doesn't soldify, insuring that the water is mostly gone and that not too much sublimation has occured (some is inevitable and even desireable). The yield of Methylamine HCl should be around 200g as white deliquescent crystals. Note, ACS-grade methylamine HCl is colorless. We aren't using ACS-grade production techniques here, so don't expect ACS-grade product. However, the methylamine produced by this method is eminently suitable for the many purposes normally intended and if allowed to sublimate some when heating, no adjustment for "purity" or "water content" need be made in subsequent uses of it. . If the crystals are opaque white and do not deliquesce quickly in air of average humidity (65% rh), they may be contaminated with some Hexamine or some bizarre polymer. [Or ammonium chloride. Recrystallize from methanol, then wash with CHCl3]. Washing 100g of the crude product with 100mL of Chloroform by stirring in a beaker then enhancementing, repeated as many times as necessary, will remove Hexamine. Methylamine HCl is insoluble in Chloroform whereas Hexamine is at the rate of 1g to 10mL. As a final note, I have been informed that hexamine is available in some areas in the form of "fuel tablets" for small camping stoves. I have received mixed results from various individuals using this so, as the saying goes, Caveat Emptor.
