Have you thought about Biuret perchlorate? Biuret can be easily made by heating urea, so why not to try it?

Here is a paper describing biuret perchlorate detection.
Biuret Perchlorate

It is pretty strange that oxygen is protonated instead of NH2 group.

The oxygen would be protonated rather than an amine group because the amine group is electron donating to the oxygen.



This is the reason why amides groups are so much less reactive than ketones, aldehydes, or amines.

Urea Perchlorate seems interesting material. it has much Nitrogen. I made a search for it but couldnt find much info rather than :

urea_perchlorate.png - 179kB

any more info about its properties ?

Urea perchlorate (and also urea nitrate) are very impractical energetic materials because of their high acidity and simultaneous hygroscopicity... a really bad combo. Urea is a very weak base with a pKb(BH+)=0.18 (wikipedia), so it only forms salts with strong acids and those salts are themselves very acidic indeed.

In some respect, urea perchlorate can be viewed as a source of anhydrous perchloric acid, i.e. because of the ease with which it can be deprotonated. Since perchloric acid forms dangerous and sensitive explosives with a wide range of materials, this is a further reason that this perchlorate hasn't made it into mainstream use.

Indeed as has been stated earlier on in this thread, the related guanidinium perchlorate, being the salt of a strong base and acid, is a MUCH better way to go.

Better is Guanidine Perchlorate formed by reacting Sodium Perchlorate with Guanidine Hydrochloride.

Non-hygroscopic, moderately sensitive to impact and has considerable power.

1,15 g/ccm = 6000 m/s
400 cm3

It's Explosive appropriate force tetryl.

Even better would be:

-Biguanidine diperchlorate
H2N-C(=NH)-NH-C(=NH)-NH2 . 2 HClO4

-Pentaerythritamine tetrapechlorate
C(-CH2-NH2)4. 4 HClO4

unfortunately, I didnt find any info about both materials on google.

Biguanide diperchlorate and process for preparation thereof
US 4340755 A :

http://www.google.com/patents/US4340755

Would it be possible, by reaction Biguanide hydrochloride with sodium perchlorate ?

Yes possible.

Also another interesting possibility:
H2N-C(=NH)-C(=NH)-NH2 . 2 HClO4
the diperchlorate of the diimino derivative of oxalamide

I could synthesis now perchlorate and I would like to go further and make Biguanide diperchlorate !
sorry if my question looks very basic but i found very hard ways to synthesis Biguanide
isn't there some practical steps to be synthesis Biguanide at home in my small lab?
