Azole-Based Energetic Salts reports a more reasonable 8786 m/s at 1.54 g/cc.
I don't think it should be compared with RDX in terms of brisance though, because the detonation pressure is much lower at 248 kbar. Still very
impressive for something so simple.

I recently found an alternativ and very easy synthetic route of / 2,2-dimethyl-5-hydroxymethyl-5-nitro-1 ,3-dioxane /
which is one precursor of the super explosiv BHDBT
It was dicussed one site before.
//
The way to obtain 2,2-dimethyl-5-hydroxymethyl-5-nitro-1,3-dioxane is illustrated by the following example.
To a mixture of 15.1 g (0.1 mol) of Tris-(hydroxymethyl)nitromethane and 50 ml of (0.68 mol) of acetone
with stirring and a temperature of 10°C sprinkled 5 g of phosphorus pentoxide. Stirred the reaction mass for
10 minutes, then poured into 100 ml saturated potassium carbonate solution with ice. Stir to dissolve the ice,
then the product is filtered, washed with cold water and dried in air. Gain of 11.5 g (71%) of
2,2-dimethyl-5-hydroxymethyl-5-nitro-1,3-dioxane with TPL 133-134°C.

Very nice finding!
(CH3)2C(OCH2)2C(NO2)-CH2OH could also be halogenated to (CH3)2C(OCH2)2C(NO2)-CH2I;
then allowed to react with AgC(NO2)3 to yield (CH3)2C(OCH2)2C(NO2)-CH2-C(NO2)3;
then deprotected to yield (HOCH2)2C(NO2)-CH2-C(NO2)3 and finally nitrated to (O2NOCH2)2C(NO2)-CH2-C(NO2)3 (2-methylol-2,4,4,4-tetranitro-butanol
dinitrate = C5H6N6O14)
An energetic material with slightly positive OB:
C5H6N6O14 --> 5 CO2 + 3 H2O + 3 N2 + 1/2 O2

LU Ming jiu (Xi′an Modern chemistry Research Institute, Xi′an 710065,China)
The synthetic, structure, properties, and some applications of a new explosive 2,4,6,8,10,12 hexanitro 2,4,6,8,10,12 haxaaza tricyclo〔7.3.0.0 3.7
〕dodecane 5,11 dione(HHTDD) are described. The crystal density and detonation velocity of HHTDD were determined as 2.07 g/cm 3 and 9546
m/s.(ρ=1.995 g/cm 3) respectively. It is the first explosive with so high detonation velocity reported in references up to now.
F. de Lalande and M. Prud'homme showed that a mixture of boric oxide and sodium chloride is decomposed in a stream of dry air or oxygen at a red heat
with the evolution of chlorine.

In my previous post I described the hydrazinium salt of 5,5'-Bis(1H-tetrazolyl)amine (not the ammonium salt. A fault in the document)
Synthetic route to 5,5'-Bis(1H-tetrazolyl)amine is decribed here:
| Quote: |
Synthesis of H2BTA•H2O (C2H3N9•H2O), (1)
As described in the literature[4], (Fig. 1) 4.45 g sodium dicyanamide (50 mmol) and 6.50 g sodium azide (100 mmol) were dissolved in 40 mL ethanol and
25 mL water, and then 75 mL of 2 M HCl was added dropwise over 4 h with stirring. The resulting mixture was refluxed for further 48 h. After cooling
to room temperature, 10 mL of 12 M concentrated HCl was added and then 60 white precipitates were filtered. The crude white solids were dissolved in
hot water, and then cooled to give white crystals 1.
IR (KBr): ν = 3455(s), 3030(s), 2932(s), 2857(s), 1651(vs), 1611(s), 1555(s), 1456(m), 1353(m), 1261(m), 1152(w), 1108(m), 1072(s), 1043(m), 1003(m),
903(m,br), 820(m), 740(m), 688(m), 509(m,br), 405(m) cm–1.

This is then allowed to react with hydrazine to yield the compound with vod of over 9900m/s

Is there an other route to 5,5'-Bis(1H-tetrazolyl)amine? Pretty difficult
How to get sodium dicyanamide?
BTW does someone know how to syn. 5-Azido-1H-tetrazole? Maybe start from 5-Aminotetrazole?

I found that.
Some very energetic salts based on 5-hydrazino-1H-tetrazole (5-Hydrazinotetrazole) (HTZ)
High energetic compounds with easy synthetic route. The only drawback is that you have to use the silver salt. I guess otherwise you will have some
impurities. The only common is silver nitrate

Glycolite
It was tested a little-known plastic explosive. The working title is Glycolite. It shows very good results. It contains 12% water, NaClO4 and
diethyleneglycol. This is the basic composition. Sensitizing are: aluminum and microballoons 1-3%. VoD is estimated to be 5,000 m / s or more.
According to the charge diameter and length of course. Details on Channel Laboratory of Liptakov........

Very nice!
Glycerol could be used aswel with slight variation of the % for OB --> glycerolite 
This would be more viscous, denser and so VOD will be slighly better.
One may even think to a syrupy mix of erythritol and glycerol for even better density.
Or suggar syrup (corn syrup).
The use of NH4ClO4, HONH3ClO4 or N2H5ClO4 in the formulation will boost things up even more.
I wonder if NaClO3 what is more soluble and sensitive could be used instead of NaClO4...?
In principle nothing is against its use (no NH4, nor acid nor sulfur) in the original formulation.

Despite having a lower oxygen balance than perchlorates, chlorates tend to be much more unstable and sensitive to heat, friction, and shock. From my
experience, chlorates should be avoided due to the susceptibility for an accidental detonation, degradation and sensitivity over time.

Both articles are now available (a little after my request thanks to Solo in the reference section under pdf format (see link hereabove).
And hereunder are some infos from Franklyn on tetranitratoethane related methylene dinitrate or dinitratomethane (CH2(ONO2)2 geminal dinitrate ester
of dihydroxymethylene (formaldehyde hydrate aka CH2(OH)2 <=> CH2=O + H2O).
Methylene dinitrate
This is a new interesting family of compounds (H-(C(ONO2)2)n-H) that shows maybe promising HE properties, but they are easily hydrolysable although
the tendency seems to be reduced by increasing n.
Only two compounds of that familly are known up to now...
H-(C(ONO2)2)1-H = CH2(ONO2)2
H-(C(ONO2)2)2-H = (O2NO)2CH-CH(ONO2)2
When n increases so do:
-density
-Oxygen Balance (already positive!)
-VOD
-stability towards heat and hydrolysis
So maybe...
n=3
H-(C(ONO2)2)3-H = (O2NO)2CH-C(ONO2)2-CH(ONO2)2
hexanitratopropane
n=4
H-(C(ONO2)2)4-H = (O2NO)2CH-(C(ONO2)2-)2-CH(ONO2)2
octanitratobutane
n>4
...would prove to be even better on all those detonic and physico chemical aspects

Beware for friction sensitivity...
KMnO4 is hell a catalyst for sensitization...
Strange that you only reach 1,25g/cm3 with 55% KMnO4 at d= 2.7g/cm³ and 10-20% Aluminium also d=2.7g/cm³?
Maybe a lot of air trapped inside.
Beware for sternutative effect of ultrafine KMnO4 dust and also everything arround turning purple upon contact with moisture and finally brown from
oxydation into MnO2 spots very hard to get rid of!
@LL,
I like the comparative test flashpowder vs Manganex

Nice comparison Liptakov,
The patent below was posted many years back by quicksilver, might also be interesting to look at, especially considering the OTCness of terephtalic
acid. The perchlorate version needs a lot of confinement to "detonate" from fuse
only, but they are nearly insensitive to normal stimuli. Don't think other oxidizers were included, maybe KMNO4 may be a nice tradeoff between fuse
sensitivity and confinement requirements.

Manganex / Manganit
This mixture has not an especially advantage. Only one. When you have a not another or better oxidizer, but have every all other compounds. This mix
working much better with NH4ClO4 and working good with KClO4, NH4NO3, best with TeACN and TeACP. But it is another energetic material, another
question, and nothing a new. Next thing, VoD is low. Well. But it is potassium permanganate. Is miracle, that sample was be detonated. And no only
deflagration, similarly as flash powder.
......LL Thanks for everybody of your feedback. https://www.youtube.com/watch?v=4lTIAhJLjmo

My proffesor has synthesised hexamine where the nitro bonds are replaced with 'niflo' bonds. I have no idea how he did it. It seems unbelievably
sensitive - apparentely, it exploded in a shockproof container in a climate controlled atmosphere. He tamed one kilo of it, and ignited it with 0,5
grams ETN. It vapourised the metal at the centre and shredded the metal at the edges. Detonation velocity is around 9-10000 metres/second. If I can
find how to synthesise it, I will tell you.

Can you make a chemical drawing of the putative nitro-hexamine and niflo-hexamine? Maybe ask you teacher.
I'm sceptical about the veracity of the story...maybe your teacher told you a beautiful story...
1°) 1 kg of an explosive in a shockproof container is way too much for testing.
2°) synthetising 1 kg of an unknown sensitive explosive material is also way too much.

My teacher made and detonated a small atomic bomb in her jacket pocket yesterday.
No idea how how she managed to contain the half-megaton explosion using just Tweed and leather elbow patches ...
Maybe it was Harris Tweed.
