Hello again all.

Have just been dissolving some NC into some NM and had a brainwave!

A few weeks ago, while at work i was bored and trying to think up new combinations of fuels and oxidisers and there balanced compositions and i considered KCLO3/NM.

I worked out the formula and it turns out to b a near perfect 50/50 ratio by weight.... great! i thought, i must try that one some time but then i realised that ide never be able to get 50g of KCLO3 to absorb 50g of NM so i dismissed it and forgot all about it... untill now!

i found that when thickened with NC, NM will mix well with anything so here infront of me i now have 76g of KCLO3/NM/NC! in a 9:9:1 ratio!

Any thoughts on its power or if it will detonate and what ide need to do this? Thanks in advance!

I'm looking into this a little, since it's piqued my interest. Be careful mixing NC and NM for extended period of time, or when stored for long durations since NM is slightly acidic (0.1%max acidity). You might want to mildly alkalize the NC, though I don't see it being a problem for this so much as that blasting gel.

Sounds genius to me man. Make sure you use a powerful enough cap to det it, considering we have no idea the amount of energy needed to initiate detonation.

Unless of course someone else already knows of this?

We should check charts to see how much energy is needed to set off the NM and the perchlorate, since I'm pretty sure one would get the other going. Take the lowest number, and start from there?

Sweet. If i had chlorate and NM id give it a go!

That reminds me, a friend of mine had some nitro fuel for a RC, but i think it was only like 5-10% NM. And i remember another friend who i wish i knew better but i don't see him around anymore who raced nitro bikes and could hook me up with a bunch of probably pure if not very near!

Must find him!

It's pretty easy, and safe to distill.

Saw something online about ANFO with a 4% EGDN addition to it. Looking into it a bit, since it reminds me of your stuff.

As for what cap to use, i hail from little old england so blasting caps are a little hard to come by but i make my own with up to 5g of HMTD. I once detonated 100g of cheddite (KCLO3/vaseline 9:1)and it went real good as there was a visibe shockwave caught on camera. Ide say the VOD was about 3000m/s though the power would have been low due to CLOUDS of KCL vapour that were formed and sucking energy out of the explosion to vapourize. Ime guessing that with KCLO3/NM/NC, NM would ovedrive the KCLO3 so maybe (6250+3000)/2...

4625m/s isnt THAT impressive but not bad for sum left over shit that i mixed up!

I used a 5g cap for the cheddite so gonna try a 3g for this lil mix

Its not that hard to buy pure, R/C shop, tell them your mixing your own fuel and you can pick up a 5litre tin of 99.9% NM for less than $100 AU if you shop around a bit.

KClO3 and NM has been done before and works adding NC isnt going to change much.

Ok well you tell me how KCLO3 is going to absorb the same weight, and TWICE its volume of nitromethane without NC in there as a thickener? If i really thouhght the NC was going to change much do then why did i make it less than 6% by mass in my composition? Think you need to read the thread abit more thoroughly before you pass comment mate

Why 50:50 That is also an assumtion KClO3 with I belive 20% NM has been done but it was still KClO3 and nitromethane.

Because 50:50 is the chemically balanced mix to produce KCL, CO2, N2 and H2O only... like i said in the thread. This equates to 1:2 by volume KCLO3/NM. The whole point was that it WOULDNT mix without a thickener like nitrocellulose... like i said in the thread.

You can also get it as racefuel for cars in extremely high content, but if all you have is methanol mix, I suggest distilling, since it's practically free.

Man, you've been doing a topnotch job with this, I congratulate you.

Oxygenbalenced is rarly the best for actual preformance and KCL is well what the fuck is KCL I am fully aware of KCl but I lack any knolage of KCL.

Lets get this fucking straight all I said to start with was that mixes of nitromeathane and KClO3 have been done before you started all the bullshit I didnt mention ratios or any of that crap I was just saying it's not hte most original idea.

Well YOU started all this "bullshit" because you ignorantly stated in your illiterate wisdom that adding nitrocellulose wouldnt make a difference. Trying to belittle my idea and the thread that i had started plus COMPLETELY missing the point that i was trying to make...

Thats my say on the matter. I'm bored with this now so I'll just leave you to pick up your "fucking" toys!

Yes, i see your point. I am new to NG and have just done my second synth which i am waiting to detonate when my blasting buddy returns from Italy... by next weekend i hope as it has been sitting on my shelf for a week!

I've considered ETN and MHN but E I'd have to import from the states and M is a restricted substance here requiring end user statments of use etc.

my NC didnt gel my NG due to my lack of acetone but kinda soaked it up nice

Do you find it takes a long time for the acetone to evaporate and allow the NC to thicken your NG?

...True what you said about lowering the VOD as theres no point in making nitiglycerin only to bulk it out with crap... may as well stick with kinepack otherwise!

I have wanted to try a chlorate based dynamite just because I want to know what it would be like but it strikes me as a waste why would you want to do anything to 7700.

On a slightly off topic point but I'l go on any way I read in the science madness VOD list that frozen NG had a max VOD of 8200 since it could get a better VOD has anyone tried that I have heard it is very insenstive when frozen and its not pleasant when partly frozen.

Sounds interesting. Its just annoying that NG is so powerful and if you've got the synth licked and use an aquarium pump to neutralise and dry, easy and quick to make, yet is a liquid at room temperature.

Could well giv froven NG a go as it would be easy to cast it in the fridge around a one gram HMTD penlid cap, though to feel safe I'd want to get it WELL down below zero to give me time to get to my basting site 6 miles away.

Any ideas of for commonly found additive that could be put with the glycerol before nitration that would raise the melting point of the final product say 40 celcius?

I had to import my Erythritol well worth it if you ask me expecaly if you use it as a base charge for caps.

Making it change to freeze at 40 would be hard very hard or I am missing somthing important.

Mannitol is unfindable over here but sorbitol is 98% of sugar free polo's they have the same emperical forumula IIRC so they might be similar as explosives the only problem being the yeilds are low (maybe because I only use 91% sulphuric which works for most things) and it precipates as a lump of chewing gum like stuff.

Yes, I've looked into it and it would cost me about £30 to import 3 pounds of erythritol and judging by the fact that i get 2:1 yeild of NG from glycerol and the fact that ETN is basically NG but longer molecule, ide say 3 pounds should be enough to make nearly 3 kilos of ETN... enough to last me forever! I'd conbine 1g ETN with 0.5g HMTD in a cap i think but how does ETN compare with NG as far as brisancy, density power and usabily go if your using it for a cast main charge?

Forget i asked about the freezing point. It was a pointless question and i was half asleep when i wrote it but as for the sorbitol, i wasnt aware that it was in polos though they would obviously use some polyol or another. An isomer of M it is indeed though i think it has a couple of the 6 "OH" groups on the other side of the carbon atom and as far as I've read, it doesnt nitrate well at all and SHN is alot more unstable. Brainfever uses a combination of NG, MHN and NC for his best stuff and he says its the shit.... http://w ww.geociti es.com/bra infevert/home.html (http: //www.geoc ities.com/ brainfever t/home.htm l)

I am lucky to have use of great chem supplier and they do 98% H2SO4 and its like crystal clear colourless runny honey, check it out... http://www.labpakchemicals.com/

I try to avoid using lab suppliers to many questions (hence I use 91% sulphuric drain opener) but I have orderd from Labpak before. I havnt realy compared NG and ETN but it feels like ETN is a tad less powerful but barly noticeable.

SHN is a bitch its extreamly hard to nutralise being a gloop hard to filter but it may be a reasonable explosive but if you can go towards MNN or ETN that would be better.

OK i get ya.... just continuing along the theme of picking your brains as u are obviously knowledgable in such matters... Ide like to continue to make NG in "large" quantities and after a fair amount of googling ive learnt that multiple small batches and converting to gel as u go is the safest way rather than few or one big ass synth... but in your opinion, how much NG should i shoot for per nitrating vessel? I know there is inherent risk and i am careful but obviously i dont wanna die. My current synths are 300g H2SO4, 120g AN and 30g glycerol. If i am careful and thorough i get 60g from these after neutralising and drying. I suppose what i am trying to say is how much NG can i handle at one time that although would fuck me up good... would NOT kill me?

I realy cant put a exact figure on it because I try and keap both my charges and my synths small to avoid undue attention but I wouldnt go above 50g glycerine Maybe running several synths at the same time would be a solution but it would be extreamly hard to stir a few at the same time unless you have a magnetic stirer.
