[Question]nitroglycol
Hi All,
I am thinking to prepare nitroglycol , do any body here have an experience about it and would like to share?

One of the easiest materials to cause a runaway. Constant stirring is essential. Good purification involves organic solvents and distilled water.
Initiation: Modern cap No8 or equivalent. Anything less and you might get brisance like smokeless powder.

Thanks all for the info, I really appreciate it.
I have just few questions :
distilled water means i need purify water myself or water bottles are fine?
what is No8 modern cap ?
sorry if my questions are so newbie but i still learn

Deionized or tapwater can also work, but not optimal.
IMO you should start the hobby with black powder. Apparently you didn't even bother to google cap No8. I've had many accidents, witch are probably
waiting for you too. If you have accident with 30ml EGDN because of peroxide detonator, it can be life changing.

I tried to google cap No8 but the results seems to be dependent on my country.
do you mean that AP is sensitive to EGDN?

Usually, bottled water is purified first with distillation, then with reverse osmosis. So it is quite pure, minerals are added however, but only small
amounts.
The best thing to do is read as much as possible on the subject.
Blasting cap.

In the US that is far from true, if it say distilled then it is distilled.
If it isn't distilled it is probably tap water boiled to kill bacteria.
Sometime it is carbon filtered or some other process but it is
rare.
Your mileage will vary in other countries which have standards.

Why you want to try EGDN ? It will give to you lots of headaches as long as it has the tedency to evaporate. I personally prefer NG for that reason.

I don't know where you live in the US, but I've never seen a bottle of water that was purified only with distillation in more than five years. How can
they charge $2.50 for a bottle of water if it's purified only with distillation.

Do you realize you recommend to a complete novice one of the most volatile and dangerous synthesis that can be done? At least I've had many EGDN
runaways and I can confirm non of them has even shown a flame or anything. All the plyol group nitroesters along with MN have quite dangerous
synthesis. NC, EGDN, PETN, DEGDN, PGDN are at least somewhat more stable. Also EGDN gives almost twice the NG yield with 60% nitric.

EGDN has a Impact of 20cm, for 2kg, just a bit better than nitroglycerin! Someone please explain what the OP is trying to do...
Ral123, headache is only for some people, also you can get adapted to EGDN if you've synthesized a few times.

The headache is uncomfortable, so you suggest that:

I've washed a NG sample multiple times with NaHCO3 and distilled water. It was crystal clear and still developed a brown-green layer within less then
a month. EGDN has never done that and has never been easy to detonate with any kind of hitting.

It's obvious that the OP is looking for the next step from AP with a simple monomolecular. We should remind him about safety requirements during
nitroester production and EM in general. Start small and keep water at hand for drowning. Cool with ice/salt water bath. Add EG gradually. It's
similar to nitroglycerin so read all about that but also read about its deadly history of accidents and risks. Sobrero was plagued with headaches
because of it. Wash it till you're bored and then doubly before neutralizing. Use air bubbler or propeller to stir, no sticks thermometers or
magnets. Bubbler needs glass because of corrosive acid. And finally stop looking for spoonfeeding and start reading more. Then learn stoich and
beginner chem so you know the acid amounts. And for heavens sake don't leave it in a jar to vaporize and land in the threads, phlegmatize immediately
( yeah look it up). Although this thread really needs closed are their any EGDN specifics that need mentioned?

yes, I suggest the OP post on short question thread, most of OP's question's answers could be found here. This forum has covered countless variety of
explosives and you can just search the forum. and http://www.sciencemadness.org/talk/viewthread.php?tid=27853

IMO this is quite a risk but here are some options for novices:

Secondaries for novices-AN/Al, UN, ANNMAl and some other less complicated and sensitive. The basecharges/boosters can be a problem.

I have knowledge about energetic materials but i lag practical experience, i prepared before AP ,AN/Al ,ANFO ,..
but I never tried something with more power.
I would avoid NG because of its sensitivity and stability , Thats why I was thinking about EGDN
for EDNA : Ethylenedinitramine (EDNA) is a practical and powerful military explosive. Problem is, the routes to EDNA, as published always use either
exotic chems or very high or very low pressures to form the precursor - ethyleneurea.
thanks all for the advices and the info shared above

today , i will prepare my first sample of EGDN but I am worried a little bit about its storage.
what is the best methods for EGDN storage ?

Purification with NaHCO3, water and acetone. Store in cold, dark under water layer.

I would say, "don't", you could store it, sure, but it's dangerous.
Good luck.

I always do purification with NaHCO3, water and measure the PH !
is it a must to use acetone for purification ?
what if i have excess amount that is not needed anymore... how can I get rid of it?

What's dangerous?
@ ecos, I doubt you can achieve perfect neutral Ph without acetone.

Its stability is appreciably better than that of nitro but its higher solubility makes washing difficult . . .

I can reach around PH=7 with water and NaHCO3
I have a problem to understand how can I handle it or even transport it !

You can transport in a glass bottle, and use a dropper to take them out, I think you can also pour it but slowly.
I really wont store something almost as sensitive as nitroglycerin in my home, if your parents clean or your sister run into your your room and
accidentally drop the bottle, there would be tragedy.
Just burn it, it deflagrates beautifully with blue flame.
