1) To begin, after mixing the two acids, cool them in the refrigerator rather than an ice bath (note: cover the top of the beaker securely with a plastic bag). 2) Soak the cotton in the acid mixture for 24 hours. 3) Do not wash the nitrocellulose with baking soda water, but rather with cold water three to four times.

I used sulphuric acid 96% 60 ml with 37 grams of ammonium nitrate and 6 grams cotton sucked for 24 hours, and rinse it 3 times with water, but it didn't burn fast enough like nitrocellulose...

I like to save as much of the acids as possible. With a simple distillation you can recover both reagents and use them again for several runs. Or if you prefer you can add most any nitrate salt before distilling come out with more nitric acid than you started with. Personally I prefer calcium nitrate.

I was wondering if this could be done. Will there be less material than there was before though ? Do the acids get used up is what I am wondering, Its fascinating the process.

@@BearValleyPyronitric does get used up sulfuric not though. The biggest loss of sulfuric is probably the mechanical loss of taking the wool out of the nitration mix

@SolarSeeker45 Жыл бұрын

@@BearValleyPyro Some of the nitric acid gets chemically bonded to the cotton which is what makes it so flammable, the reaction also produces a little bit of water which dilutes the reaction mixture, it's also not possible to squeeze all of the reaction mixture out of the wet cotton so some of it gets washed away in the rinsing steps. So you get reasonably strong nitric acid distilling out, and dilute sulfuric acid with water and nitrocotton impurities left behind. Sulfuric has a much higher boiling point than water so you can regenerate it by turning up the heat to drive the water off. If you choose to add more nitrates before distilling then you're swapping sulfuric acid for nitric acid.

Your gumcotton burns slow. It should make a plump noise with a quick flash. Maybe your cotton is a bit much for your acid mixture. Drying is also an issue, if your guncotton is becoming yellow while drying, it could be deteriorating, which lowers its quality. İf you are heating it, do not. Put on filter paper or newspaper and dry in room conditions. If you store it, will also deteriorate and gets yellow. Never store large amounts together, it can self ignite. There are compounds stopping this reaction.

Shouldn’t this be done under a fume hood while wearing PPE? Especially when dealing with a strong acid like H2SO4.

@docteurvapeur 11 ай бұрын

A fumehood won't protect you from H2SO4, as it isn't fuming, although it should be done in a ventilated area, as a nitration will likely leave NOx fumes. Good PPE, like goggle and gloves, should be used.

@lagrangiankid378 5 ай бұрын

Room temperature concentrated sulfuric acid has a very low vapor pressure and no fume hood is needed to handle it. Fume removal is needed for handling of fuming sulfuric or nitric acid though and also if nitrogen oxides are generated.

You must let the cutton soak longer in the acid mix at last over 2hours. when you do it make the prove with very very small amount of guncutton because it gives an big red fireball and you feel the heat. No yellow part in the flame no ash remains and if you use an porcelan dish no yellow spot than you have real guncutton.

@peek2much3 5 ай бұрын

Something weird happened when I removed the fully nitrated cotton and attempted to reuse the acids for a second batch. The mix refused to soak the cotton thoroughly and it began to give off NO2 really deep orange (good thing I had my reservations so I was ready with my fume extraction rig). It appears that this is a one use only setup as it will totally decompose after it’s done the job. For those wondering if they can do what I did, there you have it man. DO NOT REUSE this! Oh and the neutralization NaHCO3 was more “reactive” than normal complete with deep dark foam (scary stuff). Edit: DO NOT LOSE RESPECT FOR ANY OF THIS STUFF EVEN IF IT LOOKS “INNOCENT” ENOUGH AS IT IS “JUST” COTTON. ALWAYS BE FULLY PREPARED AND READY TO ACT EXPECTING THE UNEXPECTED. My reaction and outcomes may not always match that of others. That is my #1 rule always!

Dynamite does not use nitrocellulose, it uses liquid nitroglycerin absorbed in charcoal or diatomaceous earth (same stuff as cat litter) wrapped in paper. Although, the same guy who invented dynamite Alfred Nobel, also invented another explosive called gelignite. Gelignite, or blasting jelly, is a mixture of nitroglycerin and collodion (nitrocellulose dissolved in ether).

@huhdidwhat Жыл бұрын

Everywhere in the firearms industry. It's the propellant used to propel bullets. Single based for nitrocellulose alone, it's more commonly processed with nitroglycerin though to adjust chamber pressures, just a small amount, along graphite and diphenylamine to adjust the burn rate and preserve the powder from decay. It's also used to make plastic, at least it was until it started spontaneously bursting into flames and burning entire movie theaters down. It was replaced by cellulose acetate which doesn't have the same issue.
