Catalytic oxidation of ammonia

toxic ammoNIA gas!!!!!!!!!!!!!!!!!!!!!!!!!!

WTF are you doing, not wearing gloves?!

this is a very cool video, its great to see chemistry demonstrated in such an interesting way.

its just a shame that platinum is so damn expensive.

[Rannyfash]

@FreeTheRadical i stole about a couple of grams from my neighbours catalytic converter

[FreeTheRadical]

@Rannyfash how did u manage to get it out in a usable form? as far as i understand it its not really accessible in a way that can easily be used even as a lab catalyst... it it is id love to know but it somhow seems doubtfull

[FreeTheRadical]

@Rannyfash correction:

IF it is...

didnt mean to sound so sarcastic btw

[Rannyfash]

@FreeTheRadical well im sure it couldnt be but i had a fine metal powder that would not dissolve in nitric and sulphuric acid so its possible that it is platinum or any other inert catalyst metal they use like rhodium or paladium

Like a jam jar jet engine. watch?v=LmvUavGCAD0&feature=re­lated

[Frresh123]

Just a cool idea. I will try this as soon as i can.

[j822bosh]

Yes this how the Germans where able to make nitric acid during WWI. I had to hold back laughter watching this becuase the little explosions sound like me after eating bell peppers. LOL! Great video!

[PeterCarneades]

I didn't boil the solution, so the reaction made smog only.

ammonia produce hydrogen and nitrogen through electrosis

[stylcd]

can you explain what is going on here...?

let me guess, ammonia being bubbled through water with a heated strip of ,

erm, platinum?

[bunnyfaceboy]

does it have to be a platinum strip?

[evansp12]

You need a Pt strip to make ammonia oxidize to nitric oxide, in which the resulting heat given causes the strip to glow and ignite the ammonia/oxygen mixture. However, the ammonia/oxygen mixture will ignite if the flame is applied to it.

@evansp12 as in are there other chemicals that can be the catalyst, as you know that Pt is very expensive, does steel wool work?

[evansp12]

I think there are other transition metals and oxides that act as catalyst, such as copper or nickel oxide, although I find Pt wire most effective. There is a section on ammonia oxidation catalysts in 'alexandria.tue.nl/extra2/2002­10267.pdf'.

Sorry for the delay in answering. Anybody who have better answers, please comment.

@evansp12 thx but the link doesn't work...

[evansp12]

@aeroscope I'm sorry about this. Try going into Google and type, "catalytic oxidation of ammonia to nitrogen" and click on "[PDF] Catalytic Oxidation of Ammonia to Nitrogen".

Hope this helps.

@evansp12 thx it is an absolutely stunning piece of document!

[HazMatLabz]

@evansp12 so how come the ammonia isn't just burning into nitrogen oxides?

[adriankocian]

On the video is very important reaction between oxygen and ammonia. through liquid ammonia is bubbled oxygen and to the top of the test tube is added heated platinum wire(700°C--catalyst) and the reaction is : 4NH3 + 5O2 ---> 4NO + 6H20

[vmelkon]

@adriankocian There would be some N2 formed as well.
