50% HMX Synthesis
I read this over here:
HMX is produced by the nitration of hexamine with ammonium nitrate and nitric acid in an acetic acid/acetic anhydride solvent at 44°C. The raw
materials are mixed in a two-step process and the product is purified by recrystallization.
Any safer way to make it?

What do you mean under "safer way"?
For nitrating hexamine to HMX you will need to use strong nitrating agents, like in this case acetyl-nitrate. There is no "safe" way for making these
kind of high explosives, you will always need to use acids and potentially "dangerous" things.
But if you work carefully and you do not pour the reagents on your face or breathe in the fumes, then it's not a big deal.
P.S.: if you have never nitrated before, than I would suggest to start with an easier thing and not with acetyl-nitrate made HMX.

Only if you're in the military and authorized to do so. You can also obtain it if you're doing research at a respectable organization that involves
HMX. Any other way will lead to jail for sure. Don't muck around with this stuff.

Times were different many decades ago. One of my older chemistry professors told us a story about how when he first went to university many years ago
one of the laboratory procedures in his first year chemistry class was making TNT. This would have been in the 1950's.
I'm not saying let's go kill all the stupid people...I'm just saying lets remove all the warning labels and let the problem sort itself out.

Why do you specifically say ' go to jail' in relation to HMX.
Lots of people (at least appear to be) are making small quantities of this and that here and no one suggests that they will 'go to jail for sure'.
Is HMX specifically frowned upon by big brother or was it just an off the cuf remark?

He asked where he could buy it, which is distinct from making it. You may not go to jail for synthesizing small amounts secretly, but you will
probably be reported to the Feds if you attempt to buy it from Sigma or someplace without a proper license (suspected of being a terrorist)...

Anyway, could I heat sodium bisulfate,ammonium nitrate,sodium acetate, and hexamine in certain amounts to produce nitric acid,sulfuric acid,and acetic
acid in the flask while refluxing to make HMX?
It seems possible, but unsafe.

LOL, no.
Acetyl nitrate decomposes over 60-70, so if you are not enough careful than you could easily explode. And also acetic anhydride is needed to produce
it, it won't form in high percent from acetic acid and HNO3.

Well, could I distill over fuming nitric acid straight onto some acetic anyhydride, glacial acetic acid, ammonium nitrate, and hexamine?
I think that has a higher probability of working, I just need stoichiometric amounts, anyone know the proper amounts for this nitration?

Why would you need ammonium-nitrate is you've got fuming HNO3? I don't get it.
For the recipe use the search engine and if any mods. are reading this, than I would suggest to place this thead to the beginners or the explosives
section.

Well, that's just waht it says, maybe for the heaxmine to grab some nitrogen and or hydrogen? That's just what it said right here: http://www.globalsecurity.org/military/systems/munitions/exp...

~350cc of strong, white HNO3 will nitrolyse ~50gm of hexamine . . .
Hexamine is added portion-wise over ~30 minutes!
Temperature should not exceed ~30°C!
The reaction mix is allowed stand for some minutes and drowned to precipitate the product!

First of all, that would precipitate RDX with slight traces of HMX, I just found something better right here: http://web.mit.edu/semenko/Public/Military%20Manuals/RogueSc...
Also they say Methanamine instead of Hexamine, same thing.
