new ernergetic materials


I think the nitration of pentazole gave a strong energetic material.

N5-NO2

for instance
3-nitro-1,2,3,4,5-cyclopentazole

:P

What made you think that?

Cyclopentazole should be CN5 squeleton!
The possible nitration in 3 would mean that C has 2 H and one of the N has 1:
CH2(-N=N-)2NH -HNO3-> CH2(-N=N-)2N-NO2 + H2O

(O2N)2C(-N=N-)2NH
O2N-CH(-N=N-)2NH
O2N-CH(-N=N-)2N-NO2
(O2N)2C(-N=N-)2N-NO2

Should then be also investigated!

5 membered nitrogen rings do not exist (yet :)), except the pentazole ion :(. Even that has only been isolated as a compund with AsF6-, I think, and that exploded while they were carrying out tests on it. You might want to check that, there may have been more developments but that was the last that I heard on the subject.
Tetrazole exists, I have 2kg of 5-aminotetrazole. Even on it's own it is quite energetic, if you heat some up on a spoon after a short while it will start a fairly violent self-sustaining decomposition.
The nitrate salt is really good stuff, it is the only nitrate salt I've encountered that is easy to set off with a hammer blow :D. I would guess that it would be powerful compared to other nitrates, too. A great use for it is 5-ATZN dynamite, but I don't make it too often since I have not found any safety data for the nitrate. Also when I make a batch of 5-ATZN I end up burning most of it since it makes a really nice flame :).

Wow!
Where did you get that stuff?
- You must have been selling your home for that quantity i guess....

Sigma-Aldrich??

Really keen, HLR

Nick, you should try oxidizing the amino group in your 5-aminotetrazole to a nitro group, ozone being the oxidant. Just imagine 5-nitrotetrazole! :D

I would rather not reveal my exact source, but I will say that a bit of searching on the net and a few nice e-mails can get you a lot of nice things :D:D:D:D:D.
The original plan was to make 5-aminotetrazole dinitramide, N4HCNH3(+) (-)N(NO2)2, but without dry ice (ie, using my freezer which gets to around -22*C) the yield of KDN that I've been getting is hardly worth bothering to make, and I don't get dry ice very often.
HNO2 turns it into ditetrazolyltriazine, which seems surprisingly stable (the sample I made is still here, and still seems normal...), but all oxidising agents I've tried so far turn it into a load of bubbles ;).

tetrazoles


Why ditetrazoyltriazine and not 2,4,6-tritetrazoyl-1,3,5-triazine ?
A other examble of the tetrazine family is
3,6-bis(3,5-diaminopyrazoyl)-1,2,4,5-tetrazine a stable expensive secondary explosive.:o

sorry, a little copy mistake in my last post.
The correct name of course

Ok! I see!
N5-NO2 thus nitrocyclopentaazapentadiene!

(-N=N-)2N-NO2

NH2-CHN4 -->
perchlorate NH2-CHN4.HClO4
nitrate NH2-CHN4.HNO3
nitroformate NH2-CHN4.HC(NO2)3

Whatabang!

:cool:

Why not

pentanitrocyclopentaazapentadiene
>NNO2-NNO2-NNO2-NNO2-NNO2->

or

pentanitrocyclopentaazapentadienecyclopentadiene
[{5[(-N-N-)2N-NO2]}C5H]

the topic question
was nitrocyclopentazole
and not
nitropentazole

>pentanitrocyclopentaazapentadiene >NNO2-NNO2-NNO2-NNO2-NNO2-
-This is pentanitrocyclopentaazapentane!
No dienicdiaza -N=N- here!

>pentanitrocyclopentaazapentadienecyclopentadi>ene >[{5[(-N-N-)2N-NO2]}C5H]
-Could you make a drawing, I think there is something wrong here ;) :P

>the topic question was nitrocyclopentazole >and not nitropentazole
-Unless I'm wrong you wrote in the first post:
"I think the nitration of pentazole gave a strong energetic material. N5-NO2
for instance 3-nitro-1,2,3,4,5-cyclopentazole"

I don't know what to think or to answer, you are rather confusing :o :o :( :( :) :)

:cool:

When your cyclopentaazapentadiene nitrated with five than the nito name

cyclopentaazapentadienepentanitrate

and the formula name

1,2,3,4,5-pentanitrocyclopentazole

and your aza name

1,2,3,4,5-pentanitro-1,2,3,4,5-pentazacyclopentane

:P:P:P:P:P

The draw to the double-cyclo-compound later !!

I`ve uploaded some example of non-caged
cyclo n5 and c5 components and their combinations
to ftp.

penta(nitrocyclopentazol)-cyclopentadiene
penta(3-nitrocyclopentaazacyclopentaene)-cyclopentane
cyclo[penta(3-nitrocyclopentazol)-cyclopentane]

I don`t know, the electron bounds in example 1 can be true with 4 ????

bromo-RDX?


I wonder wether it would be possible to brominate RDX...
Mild conditions.

The problem is, i know few to nothing about nitramine-chemistry.....

This could yield an explosive with zero to positive oxygen-balance and an incredible density.

The stability could be still good if bromine is used instead of chlorine, which is also less selective.

I mention this idea especially because RDX is within reach without using acetic anhydride, bromination should also be easy.
I have a procedure on how to free bromine from bromides, the stage of reaction can be monitored by the coulor of the solution.
When the bromine reacts, the solution slowly decoulorizes.

Good idea BASF!
halogenation of RDX might work but as you said the C-N link might not survive the halide.
Anyway the halide will have higher densities and must then because their OB is improved lead to higher brisance and VOD performances.

(-CHX-N(NO2)-)3 where X = F, Cl, Br or I
Those haloRDX are also interesting because they might be precursor for couplage reactions of other explosophoric groups.

Maybe a different way of action must be investigated!
CH3-O-CH=O + NH2-NO2 --> CH3-O-CH=N-NO2
3CH3-O-CH=N-NO2 --> (-CH(OCH3)-N(NO2)-)3
(-CH(OCH3)-N(NO2)-)3 +3 HBr(g) --> (-CH(OH)-N(NO2)-)3 + CH3Br(g) or (-CHBr-N(NO2)-)3 + CH3OH

Sorry to say but genealogy has nothing to do with bromination.
