I've searched for the synth of NG, and obviously found many results, but would like to see a known reliable one such as megaloma's page on E+W. I can't get there due to my ISP i belive, have seen it at a mate's house but can't get it today off anyone i know. Could someone please copy the synth into this thread, (if not a good reliable other), (sorry for being a bastard).

It would be greatly appreciated.

Nitroglycerin was first prepared by a scientist named A. Sobrero around 1847 where it was used as a medicine. It was then mass produced by the great scientist Alfred Nobel in 1864 when he developed improvements on its synthesis and a method of detonating it. The devastation nitroglycerin caused on both the battlefield and the factory earned Nobel the title "Merchant of Death." Nobel was haunted by the lives nitroglycerin claimed so he created the Nobel Peace Prize to honor champions of peace, and later, supreme accomplishments in science. His exposure to nitroglycerin gave him constant agonizing headaches, and ironically he took nitro pills for a heart condition later in life. Nitroglycerin remains in use as a medicine, but not for explosives. Nitroglycerin is a very unstable high explosive compound. The first time I tried to make nitroglycerin was back in my early undergraduate days. I was impatient and decided to make some in the dorm without observing proper safety procedures. I was out of ice. Let me just say how important it is to keep this lab cool and slow. Nitrogen dioxide, a dense red-brown gas that is very deadly, it is the reward for nitro gone wrong. I used cool water instead of ice because I never believed all those warnings. Now I do. I began slowly adding the glycerine - not a change on the thermometer. I figured what the hell, I squirted all the glycerine in, stirred it up, checked for a temperature rise, and removed it from the coolant water. I set it on the dresser and stepped out for a minute. When next I looked down the hall and into my back bedroom, a plume of red smoke and acid was shooting out of the flask with increasing intensity. I knew immediately what trouble I was in. My dorm was in a pressurized building so no windows open, that means no ventilation. I rushed in to grab my gas mask and back out to evacuate my neighbors, except the faggot next door of course, who shared nearby rooms. To make a long story short I earned myself a reputation as a potentially dangerous individual and now have small holes in most of my shirts because my laundry was nearby. Read the Safety section again. This disastrous decomposition is about the worst thing that can happen during the nitration, only very large industrial quantity batches risk detonation from runaway nitration. Nitroglycerin has more names than most, they include its proper name of glycerol trinitrate as well as 1,2,3-propanetriol trinitrate; glyceryl trinitrate; glycerol nitric acid triester; nitroglycerol; trinitroglycerol; glonoin; trinitrin; blasting gelatin; blasting oil; S.N.G.; Adesitrin; Angibid; Angiolingual; Anginine; Angorin; Aquo-Trinitrosan; Cardamist; Cordipatch; Coro-Nitro; Corditrine; Deponit; Diafusor; Discotrine; Gilucor; GTN; Klavikordal; Lenitral; Lentonitrina; Millisrol; Minitran; Myoglycerin; Nitradisc; Nitran; Nitriderm-TTS; Nitro-Bid; Nitrocine; Nitrocontin; Nitroderm TTS; Nitrodisc; Nitro-Dur; Nitrofortin; Nitrogard; Nitro-Gesanit; Nitroglin; Nitroglyn; Nitroglyn; Nitrolan; Nitrolande; Nitrolar; Nitrolent; Nitrolingual; Nitro Mack; Nitromex; Nitronal; Nitrong; Nitro PRN; Nitrorectal; Nitroretard; Nitrosigma; Nitrostat; Nitrozell-retard; Nysconitrine; Percutol; Perlinganit; Reminitrol; Suscard; Sustac; Sustonit; Transderm-Nitro; Transiderm-Nitro; Tridil; Trinalgon; Trinitrosan; and Vasoglyn. That is quite a list, most are drug names though.

CHEMICALS APPARATUS

chloroform 1000-mL beaker

glycerol buret

nitric acid desiccator

sodium carbonate 1000-mL Florence flask

sodium chloride graduated cylinder

sulfuric acid separatory funnel

water thermometer

Prepare a mixture of 200 mL of 98-100% nitric acid and 300 mL of 98-100% sulfuric acid by slowly adding one to the other in a 1000-mL beaker. Place the beaker into a salt-ice bath during the mixing so it may cool, allow the temperature to drop below 10 °C after mixing. You can keep the cold acid in the salt-ice bath or you can transfer the acid mix into a round-bottomed 1000-mL Florence flask for better heat dispersion. In either case, prepare a fresh salt-ice bath. Because of the possibility of friction, standard stirring methods are not advised. Instead, use an aquarium pump to blow air into the acids as a means to cool and stir them. Regulate the air flow so the acid is being well stirred yet not spattering out. Using a buret suspended above the flask, very slowly add drop by drop 112 mL of glycerol that has been previously cooled to 15 °C. Carefully monitor the temperature of the reaction at all times, the temperature must stay below 20 °C, preferably below 15 °C for extra safety. If at any time the temperature goes near this, stop adding glycerin until it cools. You can use the rate of addition to control the temperature. If the temperature ever rises above 20 °C it is ruined as no more nitro will be made and you are in great danger of the existing nitro detonating. If the temperature goes above 30 °C, there is a sudden rise in temperature, or a red gas is noticed, DUMP IT INTO COLD WATER IMMEDIATELY!. Keep a bucket of ice water on hand for this task. After adding all of the glycerin, allow the temperature to drop to 15 °C and sit for 15 minutes. Carefully pour the reaction mix into a large beaker containing an equal volume of room temperature water. Add this mix to a separatory funnel and allow the nitroglycerin to settle out, it will form a layer on the bottom of the funnel. Drain off the nitro layer and keep the acid waste layer for further extraction. Place the nitro back into a clean separatory funnel and add plenty of 38-45 °C water, mix, then separate. Wash the nitro again, then wash with a warm 4% sodium carbonate solution. Wash with warm water three more times. Give it a final wash of concentrated sodium chloride solution, and let it sit one day before separating the layers. Separate and check the nitro for acidity with litmus paper. If it is still acidic keep washing. It must be neutral or it will explode. Dry the neutral nitro over sulfuric acid in a desiccator, this may take several days. You will need a graduated cylinder for measuring liquids, and a thermometer to monitor the temperature.

To extract any nitro that may still be in the waste acid, first neutralize the acid with sodium carbonate solution. Next add an equal volume of chloroform to the neutral waste acid. Mix well then place it into the separatory funnel. Remove the bottom nitro layer and let it stand in the open for one day so the chloroform may evaporate. Add this nitro to the washing process above.

One unit of glycerol will yield about 2.5 of nitro. Exposure to nitroglycerine will cause severe headaches. Keep it cool, the warmer it is the more sensitive it is to detonation. Frozen nitro can not be detonated therefore it is stable BUT partially frozen nitro is extra sensitive! Although nitroglycerin is very dangerous when confined, it is merely flammable when spread out in the open air. Nitroglycerin can be destroyed by boiling in a solution of potassium or sodium hydroxide and ethyl alcohol.

Thanks a lot for that, that's a big help.

Cheers

Brainfever had made a synthesis of nitroglycerin using the HNO3/H2SO4 method. It have lots of picitures.

Is the chloroform in this used as a solvent? if so, could ther solvents be used, for example acetone? I have heard it said that when making dynamites (eg ammonia) to mix the NG with acetone to make it safer to work with (then let the acetone evapourate).

I've made small amouts of NG prepare for some of the worst headaches well the headaches depend on the person but NG is kinda scary when you are done with it, dont store it either, I stored mabey half a ounce in my basment and one night i hear a ear shattering boom i go down and theres a big hole in my shelf(thank god my chems are outside in my work shed) thats my input

Don't store pure nitroglycerin. Dissolve it in an equal volume of acetone that should stabilize it during transporting and storage. Dynamite is acually nitroglycerin absored in some absorbent material such as sawdust, etc....I think its still senisitve a sniper bullet will set it off. But much safer then stright nitroglycerin.

And cold did you neutralize the nitroglycerin?

Was there any suspended particulates in your nitroglycerin?

If so then it makes it alot more dangerous.

[This message has been edited by Starcraft (edited 06-25-2003).]

I did neutralize it for sure and i am positive there where no particals suspended but it doenst matter now, I made it like 4-5 months ago and I will never mess with the stuff again, i also dont see the point of NG sure its powerful but it has no pratical uses. ill stick with MEKP and HMTD thank you very much oh and also LE's but you kinda feel proud that you didnt lose a hand when making it so i say you should make it just to show that you can.

From my experience, liquids are more dificult to neutralize. My batch of NG was made 5 days ago. It was neutralized under sodium bicarbonate solution for one hour, then dehydrated with sodium chloride soloution. It was then extracted and stored with an equal volume of acetone. It started to turn yellow (bad sign), the PH was checked it have a PH of 6, slightly acidic, it was dumped into 10 times the voloume of water, then neutralized again, it't dehydrating under CaCl2 now.

Watch out nitroheardaces are VERY painful.

Yes indeed nitroglycerin is very powerful, I had heard reports of 5ml of it deforming half inch thick steel plates.My suggestion if your inexperenced stay away from nitroglycerin, I had heard that less then a tablespoon will send you to the hospital emargency room.

While you're at it, look at:

Wow I've been there 6 months ago. Yes I do think 100ml of nitroglycerin is alot. It was that synthesis and those pics that gave him great respect in the E&W forum.

Largest batch I ever made was 20ml.

To the person who had yellow NG after dehydration, make sure you use pure salt, not ionized or any with crap in it.

Not pyrotechnic i know, but strongly related and some may find it interesting/reassuring (well i did anyway).

The so called 'nitro-headaches' concerned me when i first heard of them as it seemed to me that an extreme headache cannot be very good for you, so i decided to look into it.

In the same way that nitrates (GTN spay) are used for heart medication by dilating the blood vessels, NG also dilates the blood vessels in the head. This causes the headaches directly, through low blood pressure. These are painfull, although not harmful to any concerning extent, and unless you have low blood pressure should prove no real health risk (excessive exposure should still be avoided).

Pete

So something that will help with the headaches is something that raises blood pressure or something that constricts blood vessels.

This does stand to reason although i would not recommend it as having two drungs in your system that affect your vessels (in heart and brain especially) in your system may not be wise. I see no problem with normal types of painkiller though (ibruprofen possibly).

Whatever you do, don't fucking take Asprin!! It makes the headache much worse.

Would wearing a gas mask/gloves keep the headaches at bay?

I dont think so... the best thing to do is to just play through the pain, and eventuily you wont get them any more...

I do suggest wearing gloves though.

I wore a mask (full face), nitrile gloves and I still have a headache. Oh, btw, FUCK IT HURTS.

Bare with it,it should be over soon. I had to deal with the pain for 5 hours, until I finally had enough and went to bed early. Dont take asperin. The expanded bloodvessel , and your blood being thinned, your blood pressure will be even lower, making your headach worse. Or something else can happan to you thats even worse then your headache.

I've got a question on nitro headaches. If you're exposed to nitro a few times, do you become immune to the headaches? Then if you don't come into contact with it for a few months, then do again, will you get a headache?

I used to know all this, but it got lost in my brain.

Why wouldn't a gas mask help? Does it pass through activated charcoal? Are the fumes absorbed through the skin? Would a splash suit help?

A gasmask will work depends on what type. If a gasmask can filter out chlorine then why not nitroglycerin fumes? Nitropglycerin molecule is much bigger then a Cl2. I also thnik you have to cover explosed skin too.

David I can recall the first time I worked with NG, which was I donno how many months ago but I was 15 at the time. Yes I had a really bad headache. Then some time later I worked with that sunstance again, the headache came back, then after 2 days I made another batch a much larger one, there I didin't get a headache. So I'm guessing you do build immunity to heardaches but not for a long time.

Good. Have you been exposed since then, and if so has the headache returned?

From what I've read, it's pretty easy to build up an immunity to the headaches, but it's only temporary. I think caffeine helps nitro headaches.

Yea immunity to nitro headaches are only temperary, from my experience.

It'd be kinda shitty if you became permanantly immune to it (which i doubt could happen based on how they work). If you did and developed a heart problem like angina or something you'd be a little screwed.

I just completed my first NG sYnth by the way, only nitrated 2 ml of glycerine so a very small batch, this is what i wanted though as i was just interested in the synth and the netralising on a small scale.

If you have angina, get PETN.

Any nitrates would work (some better then others of course), but i know that (here in england at least) they use GTN spray, sprayed under the tounge usually.

I hope this thread doesn't turn completely to headaches, but it's still on NG so i suppose it's fine really.

Tonight I'm doing another NG synthesis. This time 45ml's. I hope everything is going to be okay for me.
