Pyrophoric Nickel Hydrogenation Catalyst / Nickel Oxalate Preparation

In this video, I first prepare nickel oxalate dihydrate from basic nickel carbonate. I then pyrolyze it to form very finely divided nickel, which is pyrophoric in air. I will be using this to perform a hydrogenation in a later video.

I have used a nitrile glove with a small hole slit into it as a gasket for vacuum filtration when my büchner ring broke. It worked quite well in a pinch.

It can sometimes be used ok, but as you can see from this video it usually results in a rather crappy vacuum filtration. The air gets in around the sides and ruins the vacuum. That's why you're taught to use the correct filter size for vacuum filtrations. But sometimes it does make things easier (when you're priority isn't to get the best vacuum filtration).

great vid interesting I tried this myself using nickel 2 chloride and alu foil reacting it with hci and water to form the ni metal, althought didn't know your suppose to charge it with a base before use no wonder it didn't work look forward to the follow up vid.

Doug's Lab Cody from Cody's Lab uses that method especially to evaporate the nitric from gold solutions. Just be carefull-the metal edge tends to rust when exposed to acid.

Dont get stoneware. It can and will easily break. Get a corningware pyroceramic dish. It can survive hell and back. And can even be directly used for evaporation and/or drying. It is used by me, religiously. Search goldrefiningforum.com for 'corning pyroceram' and a "whats what" thread will be shown with tons of info on them

Did you get around to using the decompensated nickel oxalate as a catalyst? If so, how did that work out? Was thinking about doing something very similar...

@garycard1456 8 жыл бұрын

Interesting. I wonder if this procedure would produce pyrophoric and very finely divided Mn, V, Co, Cr, Ti, and lanthanide metals (e.g. Ce) from their oxalates?

@stephenjacks8196 3 жыл бұрын

The reduction potential for Oxylate is -.44 volts which is the same for Iron. Driving off CO2 helps force the reaction to metal. Zinc and Chromium are -.76 volts so probably mostly oxide result. Interesting if this method yields alloys for metal mixtures like heating Tin Oxalate (-.1) with Copper Oxalate (+.3) to make bronze.

I have analar grade Nickle chloride, over a Kg of the emerald green, and yes, your solution was a very "dirty dark green"..so I imagine you are right, it was not all that pure, also, if you had pressed that paper catch towel down snug into the circumference of the Buchner filter..( and that's pronounced "Bookner" not "buke ner" by the way) it would have helped your filtration by stopping air leaks..are you using a water aspirator for your vacuum?..it's never much good with fine ppt's like that..

@bromisovalum8417 4 жыл бұрын

I always wanted to try to make Raney Nickel the traditional way but never got around to it. It can't be that hard to make a 50-50 alloy of aluminium and nickel yet I've never seen anyone try it, neither on youtube or on message boards. I was thinking either to heat a half half mixture of finely divided aluminium and nickel in a crucible with lid flushed with welding-grade argon in a homemade PID-controlled (20$ ebay china) ceramics oven (using Kanthal resistor wire), or to heat said mixture using an induction coil. Once you have the NiAl alloy it merely requires crushing it up and digesting in 20% NaOH to dissolve the aluminium in the alloy and you're left with classic Raney Nickel, also very pyrophoric.

@danawold4547 8 жыл бұрын

Hi Doug, I probably missed the explanation, but when you made the fine nickel powder, does it need to be hot to self ignite in air as you demonstrated, or would it ignite at room temperature? If you let it cool, would it oxidize relatively quickly, or could you store it for a long time?

+Dana Wold With pyrophoric iron made from oxalate you can make it and then seal the test tube with a waxed cork and sprinkle the iron the next day from a cold test tube and it will still produce a shower of sparks. You just melt some wax from a burning candle over the cork and then press the cork into the test tube making an airtight seal. With nickel it isn't safe to breathe any of the nickel oxide smoke.

@stephenjacks8196 4 жыл бұрын

Raney alloys are just that, not pure Nickel. The product of digesting NiAl with NaOH is Ni5Al but Al can be replaced with La or Ca. Ni5Ca was the metal hydride storage for nickel metalhydride batteries (other electrode in battery is NiO2. Raney alloys can also be non-nickel like FeTi (which has the highest Hydrogen storage).
