Guanidine nitrate (nitroguanidine as well) may be not very interesting itself, but it is the start point for many interesting compounds. Guanidine
nitrate-> nitroguanidine-> aminoguanidine-> aminotetrazole-> nitriminotetrazole or nitroguanidine nitrate-> dinitroguanidine and so on.
There are many much simpler ways to make loud bang, but it is interesting for boys, who love chemistry.

What do you mean? Is there any girls who like energetic materials ?

I met one at a russian forum. And here http://www.sciencemadness.org/talk/viewthread.php?tid=8144&a... NatashaJurievna might be a girl (I'm not sure, of course).

Ok i make some searching and i can say that shaped charges are really interesting. Also i can only almost everywhere see the conical shape charge, and
how we are going to know how it is going to work better ? For example degrees of the cone, how much explosive must be used, outer diameter, length..
distance from the target e.t.c.
Also can you give to me a picture about the sticky theme of the unconventional shaped charges to understand it better ?

Underground you should take time to read the dc thread.it is full of helpful info on shaped charges. I learnt a lot there,it just takes a bit of time
to go through all the pages. It is worth the time if you want to learn more.a lot of tests and results to help build sc's that work.

Back to the topic: read this, if you can. http://www.exploders.us/sprawka/67.html and http://www.exploders.us/sprawka/68.html . Nitroguanidine and dinitroguanidine. There is another route to nitroguanidine- melt urea with ammonium
sulphamate. Urea 300 gr, ammonium sulphamate 1148 gr. 225-245°C, 30 minutes with further nitration of obtained guanidine sulphate with mixed acid.
Good news is that this mixture cannot explode, when you heat it.

Well, one can understand formulas, even written in foreign language (to say nothing about the Chinese one). But, if russian texts are problem for you,
some info can be found just under your nose: http://www.sciencemadness.org/talk/viewthread.php?tid=8911

Well, it means that you already know enough. But to start with preparation of calcium cyanamide is too problematic for us, poor kitchen (garage?)
chemists. And as you may see, it is not necessary at all. (BTW, aforementioned process might be realized simpler- CaC2 plus dry nitrogen. But this
reaction requires 1000 Celsius too...)

It looks like AN/U/Silica gel is the best way but something is wrong with the reaction
He uses almost 1:1 ratio of moles of AN and Urea (340gr AN and 320gr U ) but this reaction produces water, not CO2 and ammonia
CH4N20 + NH4NO3 = CH6N403 + H20
It needs 2 moles of Urea and 1 Mole of AN to produce CO2 and NH3
2CH4N20 + NH4NO3 = CH6N403 + CO2 + 2NH3
So something is going wrong here

I was trying to make some nitroguanidine by dehydration of quanidine nitrate with H2SO4 but it looks like i end up with guanidine sulpate !! I mix
200gr of GN with 500gr of H2S04. After that the temperature was rised a little bit. The SA started to produce some fumels like with nitrate salts and
was bubbling like a coca cola... After i drop that mixture into 300ml of water and some white crystals were formed, it was about 140-150gr. I washed
and neutralized them with some sodium bicarbonate, wased them again with some water and acetone for drying faster. That salt it does not burned at
alll, guanidine nitrate burnes better than that... also it melts really dificult, more than GN, and when it melts and decomposes, some white solid
perticipates is formed... So what is that at all ?

That is probably nitroguanidine, I think thats how it should behave. nitroguanidine isnt very energetic, have you tried to test the density yet?

No i do not, how can i do that ? Guanidine sulfate has a melting point of 290-293 °C wich is more suitable with that i have, also i can not find
anywere the density of Guanidine sulfate!

get a measuring cylinder and add water, then add 1ml of NQ, see how much gram increased, you will need a scale up to 0.01 gram though, i guess you do?

Nitroguanidine made by pouring a solution into water looks a lot like asbestos. An it is indeed very difficult to ignite.
You could measure its melting point. NQ lies around 240°C and guanidine sulfate between 290°C and 293°C.

Indeed it looks like asbestos, so it looks like i have some NGuanidine here. I will do the DubaiAmateurRocketry's density test to see what we have
here. How much possible is with this way to form GS rather than NG ?

You should have nitroguanidine, nitroguanidine is not energetic and can be bought easily so im not surprised, however it can detonate with a booster.
I did not find guanidine sulfate's density, but nitroguanidine is 1.72 g/cm³. Guanidine sulfate might have a similar density so im not sure if this
is a good idea hehe.

Yea, i also make that thought. But for what i have read i believe it is NG I was thinking if i can move now to NG nitrate
