Making Nitrous Oxide


Does anyone know how to make nitrous oxide?? from air or otherwise?

also

NH4NO3 --> N2O + 2H2O

its easier to get some whipits

im not a mod , but this isn't for energetic materials forum ... anyway ... you get nitrous oxide by heating up ammonium nitrate ( you can make it with nitric acid ando ammonia water ) , you can get it in cream can's - its the pressurised gas , and you can buy it in little contaniers used for filling bike tires under ways ( two contaniers cost about 5 $ in bike shops )

Why has this been posted in energetic materials? Furthermore, I think this topic has been discussed before.

please put it back on energetic materials!


N2O is detonable! maybe it is just insensitive or something otherwise they wouldn't transport it in large amounts without special precautions (as a explosive material). it supports combustion and unlike other nitrogen oxides it's not very reactive nor that toxic so why not using it in explosive gas mixtures? eg u fill 10/11 of a plastic coca bottle with N2O and the rest with propane. cap tightly. tape a cracker to it...

You sure it detonates?It's used in FAE's a lot I think.

Come to think of it you supose the nh4no3 could be decomposed by an explosion?This way the N20 would be distibuted some before it went of and a two stage initiation wouldne be needed.

Overheating ammonia nitrate can create deadly byproducts..please do not attempt this without the proper knowledge/facts... get some whippets if you want it that bad..

You mean NO and HNO3 and the like? Yes, they are formed, but not that much, otherwise a few members would be already dead. ;)
Overheating actually produces N2 and O2 instead of N2O. ;)

OK, once again from the Textbook of Inorganic Chemistry...

Very pure nitrous oxide is obtained by mixing solutions of equimolar amounts of hydroxylamine hydrochloride and sodium nitrite, warming gently if necessary:

NH2OH + HNO2 = N2O + H2O

Of course, who can get these chemicals easily these days?

Cheers!

To maintain the purity of the gasses coming off the molten ammonium nitrate a heating element should be placed around the top of the flask to prevent condensation which can drip back into the flask to cause undesireable side reactions. Also bubbling the resulting gasses through a NaOH solution should remove most of the acidic oxides and running through heated copper pipe jammed full of copper wool should remove any oxygen and if you want even purer you could just throw in a cold finger along the way to take out that annoying water. Best of luck to you!

thank u <i>JustMe</i>. I was very curious to know how hydroxylamine reacts with nitrous acid. I knew they react because when searching google for hydroxylamine nitrite didn't get any result.

I know this is an old topic, but if anyone's still interested there is another [somewhat expensive] method.
If you've got some sodium metal lying around, it will react with nitric oxide at low temps to give the salt NaNO. This compound hydrolyses to give the unstable compound nitroxyl, HNO, which decomposes like so: 2HNO -> N2O +H2O.

I would have thought it would be quite dangerous making NOS out of nothing (well a few chems neway), just be carefull!!!!!;)

Heat ammonium nitrate in dilute nitric acid with catalytic amounts of chloride. Not as dangerous as heating AN dry...

When decomposing Ammonium Nitrate other nitrogen oxides will form, NOx, which are irritant, toxic and acid. I think that the best way to remove them is to bubble the gas evolved during N2O syntheses through an alkaline solution, such as sodium carbonate/hydroxide and the like.

The N2O, will bubble through the solution unreacted, while the NOx will react with the base.

N2O was first made by a certain Priestley in the 18th century by heating ammonium nitrate and iron fillings together. The gas evolved was then bubbled through water. Below is a quoted reaction:
2NO + H20 + Fe --> N2O + Fe(OH)2

I think telling us what it will be used for is very important. If you are going to inhale it, buy whipits!!!!!!!!!!!! If you want to make it for a fun experiment, then pic a method and learn as much about it as possible and take precautions as to not hurt yourself.

Even if you did manage to make nitrous oxide with NHNO3 I can't see how you would compress it for storage.

"Even if you did manage to make nitrous oxide with NHNO3"

Like I said, heat ammonium nitrate in dilute nitric acid with catalytic amounts of chloride...
No risk of explosion, no nasty NOx's...

Short term storage can be done in balloons. No need to compress it. Long term storage is pointless since it's so easy to make as and when it's needed.

My 2 Euro


This is strictly about the experience of inhaling nitrous oxide.

It's not as fun as you might imagine.

1) The rush only lasts for about 15s.
1.5) The ruch isn't much fun, really.
2) You tend to fall to the floor when it kicks in.
3) You get oxygen deprivation if you're inhaling it pure.
4) You feel like a complete idiot afterwards.
5) All participants will bug you for 2 years afterwards about the sight of you falling to the floor with a stupic smile on your face, grinning like an idiot.

Trust me, I've been there, done that...

Here is a new synthesis for N2O,which is not as dangerous as N2O from NH4NO3,and it can´t explode.I think that I have time to test it next week,then I will write my results in here.

Sorry,it was my fault,I forgot it.But here it is: http://www.rhodium.ws/chemistry/nitrous.html
All you need is urea,sulfuric acid and nitrous acid.

'thefips' I'm sure it is a mistake from your part, but for the sake of precision the reaction is between nitric acid, sulphuric acid and urea, not nitrous. :)
