ANQN ans TNT. I don’t see the point. You’re taking a beyond military explosive and dumbing it down. Even if your 80 percent mix. You would have
better performance using 10 percent water and 90 percent ANQN. Water fills the goods quite nice and represents almost near max densities. Even ETN 90
percent and 10 percent water will approach performance near cast. Better yet add 5 percent Al ans use the water as an oxidizer. This will cast into
any container. It won’t harden by if it’s sealed who cares.

If the topic is military application, ie. Devices:
Explosives aren't used in powder form except in limited application. It isn't practical or ideal, realistically. If one is loading detonators, it
isn't apparent how necessary a cast or pbx is. When the vessel becomes something other than small diameter cylinder, then the need of casts and pbx
becomes obvious. When an explosive is moved or carried or subjected to higher temperatures, casts and pbxs become needed. Powder isn't suitable. Same
goes for water or liquid explosives. Present state of art is casts/pbx. Water should be kept out of explosives in general unless it's for some purpose
and going to be used without storage. Water in explosives is part of their natural decomposition as they experience in ambient environment in the
ground.

I suppose, but water does fill the voids and increase VOD.
As For PBX. Lots of new developments such as the chitosan nitrate I mentioned.

I'm not familiar with that but I'm always learning new stuff and like contrarian science, so I like the claim. I know you are aware of effects of
water with explosives, I only meant as a generality in explosives. Obviously lots of exceptions like immediate emulsion blasting etc
Honestly, with how big of a pool the amino acids are, and after the pronounced dissolving effect of aspNO3, I'm thinking about the possibility of non
hygroscopic ionic liquid as an energetic binder in pbx. For example, proline and leucine perchlorates are liquid at room temp and don't decompose
until mid 200C. that's a 200 C range of heating that could absorb powdered energetics making a pbx. The aspartic acid plastics were really quite nice
for the first hour or so.

I am down. Sounds promising. I think ANQN is promising as the main filler as well. Or even better the melem N oxides. You seem to have knowledge of
what is actually practical for industry and military. The advantages of an active ionic liquid are vast. Could also make a very good propellant being
pumped into a simple liquid engine/nozzle.

Does anyone know if it is possible for something like pentaerythritol to exchange nitros with perchlorates in its Ester? I mean, if hot melting a
nitrate ester into a perchlorate carrier, can a perchlorate ester be a possible unintended reaction? I suppose perchlorate esters must be possible
theoretically?
I was thinking ideally for an ionic liquid carrier pbx, erythritol tetranitrate would be ideal. Already common, and over oxygenated, lend some oxygen
to a deficient ionic liquid and if it plasticizes, is non hygroscopic, you have a two part all-active pbx from cheap stuff. If it cures too hard,
keep it soft with a small qty polyurea grease, which is still nitrogen heavy enough to participate in the detonation redox.

Glycine complexes with nickel and ammonium perchlorate resulting in cyan/blue hard crystal that has no melt shelf. appears to decompose at around 150
C. Judging from unreacted nickel carbonate, I would guess the complex is 1x Ni, 2x Gly, 2x NH4ClO4. I suspect the ammonia stays in the complex because
it isn't smelled during reaction, or at least I couldn't smell it. Complex appears to contain some energy from combustion test but otherwise seems to
not be overly sensitive.

Molten ETN is not an ionic liquid (since it is not an ionic compound), but of course that is mostly semantics. ETN would be a great carrier if the
melting point was a little higher and, most importantly, it was a lot less sensitive. You could look into the PTX formulations (Picatinny Ternary
eXplosive). They are detailed in PATR2700 IIRC.

Sorry For confusion, I meant ETN in an ionic liquid carrier, as a filler. Not ETN melted as the carrier itself. I composed my thoughts into writing
carelessly.
I hope anyone reading this in the future understands that ETN changes sensitivity in the melt phase. People do handle it in melt phase but molten ETN
approaches fulminate primary explosives in sensitivity. Personally, I only melt ETN for specific purposes like cheap detonator fills. IMO it's not
safe to handle in molten phase in large masses like a secondary.
To be more clear, there are several amino acid nitrates and perchlorates which are liquids at room temperature. For example, Proline is one they
report, liquid in both anions. One of these room temp insensitive ionic liquids could act as the other amino acids do, absorbing large amounts of
other energetic fillers, and plasticizing. Because the amino acid ionic explosives in question are liquid at room temp, there is a possibility they
could plasticize ETN in its solid phase without any application of heat, or perhaps very little heat, under ETN mp, where its more insensitive. In
theory, if possible, it should form an insensitive pbx because of the amino acid's insensitivity. The ETN itself lending oxygen to the ionic carrier
as a possible benefit over something like penthrite. If the pbx became too stiff after settling, as is seen in other amino acid ionic pbx, it could be
softened with a small amount of polyurea grease which has urea chains higher than 30% nitrogen content, thus capable of contributing energy to the
overall redox. A pbx with entirely active components from the local fitness nutrition and hardware store. In theory...
There is definitely huge character variability to be found in the amino acids and their potential complexes as well. For instance, GlyNO3 is
significantly less hygroscopic than the perchlorate. NiGlyClO4 is entirely non-hygroscopic and also does not melt, unlike glyClO4. So radically
different characteristics can be introduced into these materials. Exactly what complex gives which qualities is a shot in the dark however.

Ah, ok. Good to know we are on the same page regarding molten ETN. I think the application of ionic liquids as solvents/carriers for more energetic
fillers has a lot of potential. We still need to find some that aren't hygroscopic, but if the solvent action of the ionic liquid is high enough (so
it can dissolve a lot of high quality secondary), it may not have to be very energetic itself. This must broaden the field, hopefully enough that a
good material can be found that isn't hygroscopic.
IIRC, Roscoe posted about a mix of ETN and PETN that was pourable in the molten state and was surprisingly difficult to initiate. Maybe the mechanical
sensitivity was also lower than the constituents, but AFAIK, it was never properly investigated.

I tested some other amino acid nitrates. In general the nitrates are more soluble and have lower decomposition temperatures. Isoleucine nitrate is
hygroscopic but slightly less than than AspNO3. Its crystal is "harder" than ASpNO3. Its melting point is around 100 C. It melts as a clear yellow
tint liquid, very pourable. Proline nitrate is a liquid, it decomposes around 110 C which is lower than reported. It isn't really useable with such a
low decomp. There are still several amino acid nitrates that are not reported that could show promise. The perchlorates I will do after I finish
nitrates screening for hygroscopicity. Many of the perchlorates have a much wider temp range and are more suitable as candidates for melt casting due
to much higher decomposition Temps. Proline is also a liquid as a perchlorate, so I will revisit that as a possible ionic liquid for pbx. It seems
there may be chance of eliminating hygroscopicity via metal complexation. Of the metals, Cu Ni Mg seem to be most accessible, not sure if it would be
worth it to screen Fe but I will probably try it in form of ferrous carbonate because obviously Fe is the most accessible metal. Usually Fe complexes
are more sensitive and less stable than other metals but the amino acids are so stable, they may not present that same trend. Ca and K may also be
worthwhile to screen in complexing because I believe tetrazole lover checked a calcium glycine compound that he found nonhygroscpic. If non
hygroscopics can be found from calcium complexes, then they seem worth screening for due to easy access to Ca, along with K.
Of everything tested so far, glyClO4 via perchlorate salt is the best melt cast candidate. It's Hygroscopicity is medium, its complex with nickel is
entirely non hygroscopic but that complex loses ability to melt which defeats its purpose as melt cast carrier. aspartic acid was unusable as nitrate
due to high hygroscopicity but a nitrate metal complex may make it more suitable.

Iron could be very useful as a metal complex cause it can take 3 anions like trinitrate or triperchlorate meaning you can add more oxygen for better

Iron complexes are usually pretty hygroscopic and generally have underwhelming properties as compared to accessible metals like Cu and Ni or even Mn
and Zn. You might also run into issues of reducing and oxidizing between Fe ii and iii under heating, chem conditions, etc.
@Hey Buddy If hygroscopicity and sensitivity aren’t a concern, why even mess with the more expensive amino acid esters and look through MeNH3+,
Me2NH2+, and Me3NH+ nitrate and perchlorate salts. TOVEX has been used for decades as a cheap and reliable agent, and if you just use its prime
content (MeAN) as a relatively pure compound, it’ll outperform even TNT and PA with no contest. It is hygroscopic (but I’m sure it’s much less
than Gly salts) and nitrate salts would be more chemically stable than those of b-amino acids. Both MeAP and MeAN are cheap, safe, and easy to produce
as well. The only drawback is that they’d need to be used in a container since they form eutectic-like mixes with water.

That had never crossed my mind but it seems like something worth trying. IMO the hygroscopicity is a problem in this application (casting or
plasticizing) . The glyClO4/NO3 is hygroscopic, yes, but their complexes are not. So far, none of them melt, which defeats the purpose. The KGlyClO4
is also not melting... Overall, they arent looking like they are going to deliver anything spectacular, but Im committed to look a little deeper into
common amino acids. Dont want to overlook something from attrition when there is a near-potential there.
