Potential High Explosives

[Ezikiel]

Is it possible to make (isolate) Hydrazine Azide and/or Hydrazine Acetylide. And if isolated would they be compatable with Hydrazine Nitrate or Perchlorate.
I think a mixture of the acetylide/azide with nitrate/perchlorate should be very powerful.

Love your signature, thats my favorite. I have it typed in the signature place in my preferences, it for some reason does not show up. Its the first I've seen anyone else have it.

Hydrazine azide combined with hydrazine perchlorate would be a powerful explosive of the astrolite category. If we combine a mixture of ammonium nitrate and ammonium perchlorate,then add it to a mixture of hydrazine hydrate and methanol.You can form hydrazine perchlorate and possibly hydrazine azide ions,in combination with hydrazine nitrate brought by the reaction of ammonium nitrate and hydrazine.This explosive mixture could be easily detonated even with a no 6 blasting cap.But in order to avoid low velocity detonation.(astrolites are prone to this effect)it is best to use strong caps in order to obtain maximum performance.
There are some information of this azide about its preparation and its spectral properties..check this out:

Regarding hydrazine perchlorate preparation check this:

Be reminded that perchlorates are highly reactive material and reacting with equally reactive hydrazine compund is touchy.check perchlorate safety info:

Thanx for the info in Hydrazinium Azide. It sounds like a very interesting compound.
Anyways .... any info or experience with Hydrazinium Acetylide (N2H4-C2H2).
And could I prepare Hydrazinium Azide by mixing a solution of Hydrazinium Sulfate with NaN3 in ether ?

I have no info about hydrazinium acetylide,theoritically it can be produced by the reaction of hydrazine hydrate and acetylene generated by the reaction of calcium carbide and water.I think this acetylide is not stable and possibly a sensitive explosive;therefore I presume it is only of academic interest...
To prepare hydrazine azide from the hydrazine sulfate, by reacting these particular sulfate with sodium azide could generate the desired product,but the yields might not be high….You should start with hydrazine in order to get reliable or practical yield.Therefore the procedure found in that address: http://www.ijvs.com/volume2/edition4/section3.htm is the practical way in obtaining it…

[Ezikiel]

I think I'll stick to the NaN3 method as obtaining anhydrous N2H4 is impossible for me and so is preparing. Besides HN3 is a nasty thing to mess with and so is N2H4. I can't do much in Canada.
Is there no way for preparing the acetylide with N2H4*H2SO4 ?
And thanx for the website.

I think you have to convert the hydrazine sulfate into hydrazine hydrate by treating with limewater[(Ca(OH)2].There is a discussion about it in the topic hydrazine sulfate.Once you have the hydrazine hydrate you can refine it to remove some water then react it with acetylene gas, in order to form the acetylide…

Wouldn't hydrazine acetylide be N₂H₄-C-C-N₂H₄? Could this even be possible? I was thinking such structures were only possible with various metals...
Also, I should think that it would be extremely unstable.

[CodeMason]

And also, couldn't HCN or other very nasty nitriles/cyanides be formed on decomposition? This, if possible, doesn't seem like a safe thing to play with at all.

[Ezikiel]

I wasn't thinking of that kind of a structure and like you are saying, I also don't think that it is possible. The structure I am talking about is NH2NH2-HCCH similar to all the other Hydrazinium salts.

All acetylides are ^-C:C^- or dicarbide ions... C₂H₂ is acetylene gas. Thus calcium acetylide is CaC₂. I thought that since the dicarbide ion is bivalent, if there was ever a hydrazine acetylide, it'd have a structure along those lines. Could one of the forum members more well versed in chem. please fill us in?

[edit]: I just noticed that I posted this exactly one year after the previous post in this thread! <img border="0" title="" alt="[Eek!]" src="eek.gif" />

Hydrazine azide is highly hygroscopic, very toxic, and a extremely powerful, brissant explosive - in some ancient thread megalomania reported it to be 25% more powerful than HMX. The detonation velocity of anhydrous N2H4*HNO3 is said to be around 8900m/sec by PHILOU Zrealone; that's higher than any ammonium nitrate composition, including a nitroglycerine/ammonium nitrate composition. They're not too difficult to initiate.

The formula for hydrazine carbide would depend on the reaction conditions. If acetylene is bubbled through anhydrous hydrazine, N2H6C2 could be obtained. If acetylene is bubbled through an aqueous solution of hydrazine, only a monobasic salt can be obtained. Initially the salt may have a composition more like N2H6(CCH)2, but that should slowly decompose into acetylene and N2H6C2. Hydrazine carbide sounds like a rather weak, overall poor explosive to me, especially when contrasted with the power of other hydrazine salts.

Pu, just shy of 17mins!

This is Ezikiel I had to re-register as my old password didn't work after the comeback of the forum :( . Mods ... do you know why ? :rolleyes: Anyways Pu 239, I am kinda :confused: about your previous reply ..... Hydrazinium Azide is hygroscopic and extremely powerful but then you mentioned that Anhydrous N2H4*HNO3 has a VOD of 8900 m/s. So I am wondering .... did you make a boo boo or you were providing info on both of them ? :p
Also like I mentioned earlier ... I expect the carbide to form a salt similar to all the other acid salts. Like N2H4*C2H2 similar to N2H4*HNO3 or N2H4*HN3. I was also assuming it to be unstable and when combined with N2H4*HClO4 (to provide the O2 balance) should hypotheticaly make a very powerful composition :D . I don't know about their compatibility and the Hydrazinium Acetylide to have that particular formula.
