I have made discoveries in my basement:
The aim of the experiment was to make some calcium nitronate; based on my knowledge in chemistry, I know nitromethane to be slightly acidic, so does acetylene. Calcium carbide or acetylenide is thus a base and I thought that an exchange of salt could take place with an equilibrium oriented to the right due to the gas evolution out of the liquid system...
CaC2 + 2CH3-NO2--> Ca(CH2-NO2)2 + C2H2
But I noticed that
1)Calcium carbide and nitromethane doesn't react if dry.
2)Calcium carbide on contact with water evolves acetylene and generates calcium oxyde and hydroxyde. And this gives the desired product, for sure recognisable by the nitronate salt color (orange to dark brown).
So a few drops of water allow the reaction to start.
CaC2 + H2O--> CaO + C2H2
CaC2 + 2 H2O -->Ca(OH)2 + C2H2

I think the reaction to be
CaO + 2 CH3-NO2 --> Ca(CH2-NO2)2 + H2O
Ca(OH)2 + 2 CH3-NO2--> Ca(CH2-NO2)2 + 2H2O

The compound is a precipitate of brownish colour. Once dry it burns, puffs, explodes and sparks like gun cotton. My product is for sure not pure due to the impurities inside the calcium carbide, but I do think a cleaner product may be acheive by mixing pure calcium oxyde or hydroxyde with nitromethane and maybe the help of a few drops of water. A cleaner product would have better properties, I'll find out later when I'll have calcium oxyde or hydroxyde. Since properties are not yet known don't play with too big quantities of the product.
Maybe it is a new way of sensitisation of NM mixes.

It sound very interresting.
What you have make are the explosives salts of Nitromethan.
I think every hydroxyde can build an explosive salt.

Can you tell me what is when i mix aceylene with Chloraceton?

Sounds good!
Starforce, I think you are new, so i will say, Ph.Z is one of a few people on this forum that a lot of other members (I know I do) look up to and respect, for his knowledge of chemistry! so saying what you said is probably not good, sure, if you know what you are talking about, then fine, but what you said was not very good. "I think every hydroxide can form an explosive salt"??
Nitromethane isn't a hydroxide, and all hydroxides don't form explosive salts! what about NaOH! or water!! The reason nitromethane does so is, as Ph.Z said, because it is slightly acidic (due to the nitrate group withdrawing electron density from the rest of the molecule to leave an unshielded proton that can be lost) so it can split into a CH2NO2- and a H+ ion, the anion (negative one) can then combine with a metal (Ca in this example) to form the nitronate salt.

There, thats my chem. lesson for the day <img border="0" title="" alt="[Wink]" src="wink.gif" />

Oh, and Ph.Z, nice signature but here's another one:
A physicist made a bigger explosion than a chemist ever did :D

whoah thats really interesting do you have a degree in chemistry and do you know where ubechlor is i saw his name in another forum but i was too lazy to sigh up just to ask if he would like to come to the forum

the place is called <a href="http://www.deja.com/group/alt.engr.explosives" target="_blank">http://www.deja.com/group/alt.engr.explosives</a>

no, i don't have a degree in chemistry, just a great interest.
I am currently doing a degree in physics though.
And yes, i also was going to ask where uberchlor went... he is another one like Ph.Z

Sounds very interesting...
I'd never heard of a nitronate ion before. Are you sure that's its correct name?
What about using ammonium hydroxide?
NH4OH + CH3NO2 -&gt; NH4CH2NO2 + H2O
Or you could just bubble NH3 through CH3NO2.
I'll try it and see what happens... Wish me luck!
Does the calcium nitronate dissolve in water? I can see it's an ionic compound, and almost all ionic compounds do, but some don't e.g. lead carbonate. All ammonium compounds dissolve in water I think (trying to remember chemistry lessons from several years ago...), so this could be a good way of purifying the product.

You imagine I have already tried it:
*saturated ammonia solution gives heat and a dark brown solution of NH4CH2NO2 but :-( I was not able to isolate the salt by evaporation (even in the cold)-I suspect the compound to be very unstable it decompose into its elements maybe due to an equilibrium in solution:
NH4OH + CH3-NO2 &lt;==&gt; NH4CH2-NO2 + H2O.
*saturated solution of NaOH (solid prills) gives a lot of heat (you might expect an explosion or a fire!!!) but the isolated salt don't give interesting results (except if confined and dry).
The NaCH2NO2 is difficult to dry because it picks up water from air. It burns with puffing flammes. I guess it would explode if confined in an enclosed metal pipe and heated by a surrounding heat source like Black powder or Na chlorate/suggar or a fire.
*hydrazinium hydroxyde give slowly a brown colour but very very slowly... so I gave up.
*KOH gives a precipitate with a lot of heat also (fire or explosion to expect without water cooling or if big quantities are made).
Less difficult to dry than the Na salt. Burn fiercely like NC outside and once confined surely it will go boom.
*Ca salt I made has the advantage of being dry, precipitate, burn fiercely and explode when confined (very easy to use).

So you think the NH4OH one is a reversible reaction? Yeah, could be.
I'll stick to the calcium salt.
Do you have any information on storage stability, incompatabilities etc.?

I'm working on it but remember that I made that discovery one month ago, so I can have ideas of the stability of it for a longer period. All I know is that it is easy to dry because it is a precipitate and that it doesn't pick up water from the air. It seems to be stable towards friction or shock; doesn't detonate in the open with a flamme. I have made a device to be tested at my father's house in the country side (less dangerous and suspicious than in the city where I live): this to test the explosivity when confined or actuated by a primer.

Oups again-I must be tired:
I can't know the stability on a longer period.Something I can tell is that it smells a little bit like ammonia (sign of a decomposition? or a reaction? or transformation)... or maybe acetylen.
Following Ubi, methanenitronate of Hg turns slowly into fulminate of Hg.... maybe mine will trun into fulminate of Ca? Anyway it is an interesting compound.

woah thats weird I was at that forum half a year before I came here and I read one of uberchlor's posts that had a link to this forum and I was looking for a more relaxed explosives/weapons forum to go to because most of the guys there are all assholes

of course I knew very little about chemistry when I used to post stuff there
(before I hit the books for a couple months)
and wasn't used to all of the lingo that they use. but now it seems like common knowledge to me and I might go there once a week just to see what is going on

As a mather of facts if you take a closer look to the same forum (alt.engr.explosives) you will see that I often go there.... usually I sign with the same name as here!
I can't talk in the name of Ubi but I do think he stil read the forum but keep quite since a while because- wel that's what he wrote me- he dislike the idea of someone using his knowledge to kill himself or others....He also is borring reading always the same shit (and questions) and repeating himself every two weeks because guys don't take the time to go in the archives.He wants to progess and know more about the field... so he found out better to read and write down what he don't know yet... and sometimes when he realy think it is appropriate to reply. He has become a true genious in his kind... he learn a lot by himself and has a big pile of files collected during the last 4 years. He has become a real searcher and wants to make full studies...scientificly...what doesn't seems to be the deal of a lot of KEWLBOMBERS and KIDS playing arround here in the NG.

Personnaly, I agree with him but I know that whatever I do, there will always have people who can find the way to kill others finding the info's somewhere.

There's a large discussion concerning the ethical problems caused by giving people pyrotechnic information at the pyro forum at <a href="http://www.xinventions.com," target="_blank">www.xinventions.com,</a> under the heading of "E-mail me if you need info" or something like that.

I have to caution anyone thinking of working with these. Salts of higher nitroparafins are stable in themselves at least chemically but those of nitromethane arnt. As suggested earlier they do have a habit of turning into fulminate salts, mainly when isolated as solids, which if these were workable would constitute a useful method of manufacture, however they arnt. Mercury fulminate can be made by precipitating the mercury salt of nitromethane, and when digested by HCl, this converts slowly into the product but.... What little infomation I have on sodium fulminate for example says its much more sensitive and the solid can explode when "lightly touched with a glass rod". This rather screws up attempts to make less toxic fulminates by metathesis (as solution metathesis has to follow production of the solid group I/II fulminate), cf TM azides versus shock stable sodium azide. When ppt from anhydrous alcoholic solution the solid sodium salt of nitromethane will explode when wetted with water, the temperature rise being enough to start the conversion to fulminate, turning it yellow and the furthur heat increase setting it off (p.a.s. smith). Since its a solid state dehydration, its unlikley this can be done in solution, and therefore safely. If someone wants to experiment in trying to produce fulminates other than mercury (silver by the direct method might also be possible, and therefore as safe as silver fulminate itself is) the risks are probably managable following more information, but this is certainly not something anyone would want to happen by accident.

Does anyone have any specific information on group I or II fulminates?

Hello @ll, its my second post and i hope i dont violate the forum laws! Moreover i hope my english is not too bad :(

2 days ago i made Ca(CH2NO2)2 by mixing pure NM with Ca(OH)2 and a few drops of water while stirring. As i didnt want to make big quantities i have now about 0,5g Calcium nitronate. It looks like Cinnamon powder when dry (and pulverized). It was easier to make than NaCh2NO2, which i made about a month ago and dropped because of a strong smell of Ammonia after half a day stored dry, because the temperature is easier to control.
Zaibatsu had some impurities in his product because he used Calciumcarbide. I used pure Calciumhydroxide + CH3NO2 and i do have some bigger crystals in my product, i tried to separate them and they look a bit darker than the other product. First I thought that these are just bigger crystals of calcium nitronate but the powder of the crushed crystals does have a different colour too and when they "explode" in contact with flame they show a more red flame, where the powder of calcium nitronate shows a yellow-orange flame.
Another observation i made was that if some of the cinnamon colour nitronate was heated on a spoon it turns a bit darker far before decomposition.
Has anyone got an idea what the crystals could be or what happens with heated Ca(CH2NO2)2?

PS: I have pics from the things described.

++++++++++++++++++++++

Voryon:

1. Lack of capitalizing the letter i when referring to yourself. It's I, not i.

2. Using a symbol, @ , instead of a letter, a, in a word, is what we call "k3Wl", and is unacceptable. :mad:

3. You at least used the RETURN key to make paragraphs, but you forgot to include the space between them. :rolleyes:

Other than that, you're OK.

The general opinion seems to be in the books that what is formed is not the methylene nitronate, but a decomposition product of this. Unless the reaction is done in absolutly anhydrous and room temp or below conditions, say ethoxide as the base in alcohol, which produced the very water and heat sensitive nitronate with ethanol of crystalisation. Hydroxides cant be used as they produce water.

End product, we think, is a salt of nitroacetic acid in the case of the sodium salt but we dont know if it goes this far on just mixing a hydroxide with NM.

Theres another thread by Axt in which this was discussed.

Is calcium nitronate really an HE?
Has anyone information about the velocity of a detonation or about the lead block expansion, or about it's sensivity?

Today I dropped almost all the "Calcium nitronate" I made, because of a strong smell of ammonia when I opened the container where it was in. It has been stored for 12 days and I controlled it everyday. I just kept a very small amount to see what will happen with it.

Does anybody have an idea what chemical reaction(s) take(s) place?
