Guanidine chemistry and complex salts

symboom - 17-3-2017 at 18:19

Im in that part of chemistry the hard to find rarely performed chemistry

So I have guanidine nitrate
I havent be able to find any soubliity information
I have read that guanidine nitrate
Can form nitroguanidine
Then reduced to aminoguanidide
Then added to nitric acid to form
Aminoguanidine nitrate
Then converted to nitroaminoguanidine by dehydration

I chose nickel because
Hexamine nickel perchlorate is insouble in water
I figure maybe other compounds are also insouble
Many copper complexes require ethanol or other solvent to precipitate

Is nickel guanidine nitrate
Nickel guanidine perchlorate
How would those be formed

Nickel nitroguanidine perchlorate?


Possible if so what are the properties

It is often hard to find good solubility information for organic compounds. I remember seeing a searchable database that also showed model predictions for solubility somewhere....

Perhaps some answers may be found in this document. i dont really have the time to browse through it thoroughly but is is a useful reference for this material and may have the answers you are searching for either way i found it quite interesting.

MOST but nit ALL nitrates are soluble ALTHOUGH this was derived from A-level exam material. And is untrue, some nitrate complexes are AQ insoluble,

Update on a couple of attempts with complex salts

Synthesis: Hexamine nickel guanidine nitrate
A ammonia nickel complex was added to guanidine nitrate no insoluble precipitate forms

Synthesis: Guanidine perchlorate
Ammonium perchlorate and guanidine nitrate were mixed then chilled until half frozen still no percipitate

Synthesis: guanidine hydroxide
Ammonium hydroxide and guanidine nitrate no precipitate forms

Cant seem to figure out how to complex with guanidine
Yes I know if processed further to aminoguanidine forms a complex

guanidine primary

On a long lonely journey of finding "a" primary that isn't azide. of course that probably means the journey will end with an azide. (thinking about Bi). Anyways, now I'm here.

I started with nitriminotetrazole salts, passed by aminonitroguanidine "laser ignitable primaries", then rounded the corner to aminoguanidine metal perchlorates. Now I have parsed it down to guanidine. If that doesnt pan out im going to lay down with SA-DS and Azide or aminoguanidine salts.

Guanidine salt can be had where Im at via guanidine nitrate. I already buy this (a lot) for nitroguanidine. I have learned that Guanidine is a very labile molecule for coordination with oxidizer and metal moieties, it is used all the time in pharma, crazy metal organic coordination complexes in medicine are all over search results. For some reason, Guanidine complexes are practically unexplored in energetics.

Simple Guanidine perchlorate is already sensitive without any complex of metal moieties. Picric acid is a respective 85 cm drop to guanCLO4's 50 cm. Vd of 6-7.15 m/s. It seems like guanidine should behave very similarly to the aminoguanidine metal perchlorates which are already appreciated here. The aminoguanidine metal perchlorates look perfect, but they have only one problem for me. In theory, they are two steps further-away from a hypothetically equivalent guanidium compound. Thats enough to make me consider guanidine.

It seems that people have encountered difficulty in preparing guanidium perchlorate from anything other than HCLO4. possibly issues with precipitation? Obviously a meta reaction would be much more convenient than HCLO4.

Id like to look for a guanidine perchlorate primary.
What can I do/ should I do to test out and locate a basic guanidium perchlorate based primary explosive?

My gut tells me to begin with aminoguanidine diperchlorate hydrate methods but supplement guanidine nitrate for the aminoguanidine.

At disposal, I currently have: NH4CLO4, KCLO4, NH4NO3, (NH2)2CNH.NO3.
For metals Ive got:
Cu, Mn, Ti, V, Sb, Pb, Ag, Bi, Sr, Ba, Ni, Zn

I have no perchloric acid and have never made perchloric acid (for some reason), so I am unfamiliar with its behavior.

There must be a guanidine perchlorate primary, it only makes sense. What is the best metathesis reaction for metal perchlorates from NH4CLO4? Also, Most of the metals are in oxide form.

I think the obvious Target to begin with is Ni/Ag Guanidine Perchlorate, perhaps coordination with amines? No amines? What do you think? I could use advice. I dont even know what I'm doing.
