Will firestarter hexamine work?
So I was planning on making RDX with nitric acid and hexamine(also known as methenamine, or Hexamethylenetetramine)and I saw on ebay where it is sold
as fire starter.Will this work or is it not the right chemical?

That will work but you should ensure that there is no wax binder added.dissolve the hex in water filter out the crap if any and evaporate the water,
you should be left with a relatively pure product. Turn it into HDN for better yields though. Plenty of information on this in other threads here.

I know this sounds dumb but what is HDN? I cant seem to find the definition on the forums and google says
its a disease.Sorry this is my first time posting.

So I could use the same process as the one below but with hexamine di-nitrate? (copy and pasted)
Slowly ad 25gr methenamine to the HNO3, which went quite easy keeping the temperature under 30degr C
After that put the solution in a water bath of 60 degrees C, letting the temperature of the solution rise to 55 degr C Keep it at this temperature
for 12 minutes.
Then cool it down in a ice bath to 20 degrees C
During this phase some rdx becomes visible in the solution.
Let it stand for 10 min.
Then add to the solution 400 ml of ice water
A lot more of rdx will precipitated out of the solution.
Let this solution stand for 5 minutes
After filtering neutralised the rdx with 400 ml 5% sodium bicarbonate solution.
The yield after completely drying was 29.7 grams which is if I am right is about 74%

Looking back at some old notes I have it seems that If I am correct you can use up to 25g of hexamine di-nitrate to 50ml of nitric acid. Ihaven't
actually made this amount before but using the straight hexamine I have tried small amounts. The yields were pretty poor so I chose to use my acid on
other things that don't require so much conc HNO3.
What strength is your nitric?
Keep in mind you need at least 97%+ for a decent outcome.

Welcome to the wonderful world of energetic chemistry.
There are sections of sciencemadness.org forum JUST for asking questions like this:
Reagents and apparatus acquisition
There are more than a few existing threads devoted to making hexamine dinitrate (HDN), RDX and over the counter resources for such:
Look, UTFSE first from now on, OK? The acronym "UTFSE" stands for "use the f****** search engine" and is likely to be the first reply to a commonly
posed question. ESPECIALLY if opening a new thread needlessly to ask it.
Here are some site policies you might want to look at:
So, this is it, welcome and happy quality posting
Remember:
It is ALLWAYS better to post in an existing thread than to open a new one!.

Think?
KNOW.
By doing an acid/base titration, perhaps.
Or if you've got a good scale and an accurate graduated cylinder-
You could determine % from density at a known temperature.
I am now going to shut up until someone posts in a way that makes it obvious they are really trying to think before they leap.
Browsing the stuff in "beginnings" might help.

Yeah I actually haven't made the nitric acid yet. I am going to this weekend, and the procedure I saw on youtube isn't clear about the concentration.
Thank for the weight chart though, I was going to use one of those and I couldn't find one anywhere on the internet. I am going to start off with
making the simpler syntheses like making nitrocellulose( I prefer the explosive side of chemistry) and I was just asking this for future reference.
Thanks for helping though.
Btw: Can I delete this thread so it wont clutter up the forums?

Is it legal to assist the OP in thread suicide? RDX synthesis has some very subtle nuances that will require alot of reading on these threads. If
you aren't willing to put in for this reading first you should hold off on RDX since you'll be wasting nitric acid that could be better spent on other
projects. Unfortunately the lure of easily available hexamine is about the simplest aspect. Once it goes into nitration its a darwin's grabbag of
nitramines floating around, this is why the low yields was mentioned earlier. The nitric distillation alone has its own nuances to get up to high
purity. Low acid % is just a nonstarter completely, but you'll read about that on the threads. Bert is spot on, and here's another search hint, use
the domain function with google (or whatever) site:sciencemadness.org, add it to your search term, because things like HDN are all over, and
often with this abbreviation.

Maybe you should spend the weekend reading and taking notes?
Do you know which common glove material tends to catch fire from a high % nitric acid spill?

I was planning on using butyl rubber gloves, as far as I know they don't catch fire when touching nitric acid. I know they dissolve faster than
neoprene but I don't plan on keeping them on if I have a spill... I know all the dangers and safety procedures, Im only making a small amount of
nitrocellulose.

Your signature is probably not the right idea to have coming in here.
Other than that, you'll be fine with butyl gloves. I have gotten kind of careless before with the handling of nitric acid and even spilled anhydrous
nitric acid on my skin a few times, it was not painful, probably because it was just my finger, but did stain my skin yellow, just how silver nitrate
stains skin black.
Nitrile gloves catch on fire after a few seconds when nitric acid is splashed on
Nitrocellulous would be a good choice for a start, I've never made it though myself, even the direct nitrolysis of hex amine might be good practice to
RDX, you need nitric acid at least 95%, this means distillation from nitrate salt and slight excess of sulfuric acid for full dehydration.
Don't worry about yellow nitric acid, or contamination with NO2, you can still get RDX from this nitric acid. Find a reputable procedure from a
scientific paper to find what temperature you want for the reaction and other details

I am making nitric acid by distilling 98% sulfuric acid and potassium nitrate at around 100 degrees Celsius. Im a newbie so sorry for the useless
thread.

Once more: your time spent reading & planning before will increase productivity & reduce lifelong scars and/or death from NOx inhalation. Skin
grafts and trashed lungs are bad things.
So research:
Nitrogen oxide (NOx) inhalation hazards (like death...)
Bumping (leads to boiling acid showers)
Boiling chips (might reduce bumping. Maybe.)
Oil bath
Vacuum distillation
Nitric acid without distilling from Barium, Calcium or Magnesium nitrates & Sulfuric acid.
Nitric acid distilled from (cheap!) concrete etching solutions of Nitric acid & Phosphoric acid
Concentrating azeotropic nitric acid with sulfuric acid- Or anhydrous solid chemicals, like Calcium oxide- Or methylene chloride- Or Phosphorous
pentoxide (ha, like you've got that).
Nitrocellulose or nitroglycerin from Sulfuric acid and a nitrate, with no nitric acid preparation required.
If you ignore all the advice and just GO DO IT RIGHT NOW!!!, please have a friend at a distance with a video camera, have him post any "interesting"
video here for the next guy who is in a hurry to watch.

What makes you think I haven't researched those things? This method of getting nitric acid is one of the most efficient ones I found anywhere on the
internet, and I have been studying these methods for over a month. I did find 68% nitric acid for a very good price on a website, but I don't want to
attract any attention not to mention I have already ordered these chemicals before I even made this thread. I know perfectly well what Im doing and
all the dangers of the acids/acid fumes and the explosives I plan on making with them. I am not using a vacuum distillation setup as those are a bit
advanced for me atm and I am a beginner in chemistry. That doesn't mean im some nine year old who doesn't know how dangerous nitrations and other
processes using acids are. Thanks for warning me about it but it really wasn't necessary. I will try other ways of making nitric acid in the future,
but don't think im dumb enough to try to make RDX with nitric acid below 91% concentration. I know what im doing and have actually talked about it to
my uncle (who is a chemical engineer). I honestly don't know why you are insulting my intelligence and not some other amateur chemists on these
forums. Don't confuse me for an idiot who doesn't listen to others when doing these kind of things. I am asking on a science forum, after all.

Loosen-up, Bert , he certainly has done quite a bit of research.
TheAlchemistPirate, I wouldn't buy the 68% nitric acid, either way you'll still have to distill with sulfuric acid to get it to
~98%, so it would be a waist of money, as sulfuric acid and nitrate salts are cheaper.

Why you?
I was among the last persons to communicate with "phone", aside from his school friends who got splattered with his bloody remains. I sometimes wonder
what other thing I could have said instead of what I told him that night, that he would have understood and maybe not died like that?
You reminded me of him. You still do.
You asked for verification of raw materials for RDX.
Didn't know VERY basic information related to that process.
Offered no indication you had studied accurate sources.

Phone's post before he killed himself that weekend are definitely on the E&W archive. See "Storing the AP" on the archive and you'll see his
post... =========================================== phone February 21st, 2004, 07:08 AM i wonder if in europe there is anyone that uses mehenamine
for fire tablets or other things..i found only petrol derivate tablets... Yeah. They´re german, I don´t have the pack right here, but it´s almost
pure methanamine (or how you now spell that lame word). You just solve it in aceton and you get it pure (or was it water) I haven´t really memorized
it since I am an AP lamer (but I do own a pack with methanamine), HMTD is nutting for me , but hey, first time I did AP I did 80 grams, second 120
grams, third time (yesterday, drying today) something about a kilo or more... I GONNA BLOW MY FRICKING ARMS OFF! And yeah, I don´t treat AP with
respect, but well, I got plenty of cold, snow and ice outside so my AP is usually quite resistant against pressure e.tc. Well, right now my brain
feels like weird, I gonna have to put up a few lamps e.tc. (it dried overnight, switched the newsspaper it was on) and I think I gonna put up a few
lamps to get the bitch dry faster. Well, my moms out of the weekend, that´s why I am sitting here with over 1 kilo AP and lots and lots and lots AN.
Well, sure, I spam... but.. hey! Well. Well, almost forgot, I always take all my explosives and just make 1 big fucking bomb of it. 1 kilo AP and a
couple of kílos AN coming up. =========================================== .

Don't get all huffy when those who know more about explosives school you on it. You came here to ask the question and got an answer and additional
info out of concern about you doing it properly and not blowing your ass off. Best to read around the forum a bit more before experimenting.
