  • we never seen it do that before it normally the shatters or it just about holds.

  • But I've never seen Ah, holy experiment like this.

  • We're going to show you on organa metallic.

  • So organic metallic just means that there's carbon.

  • Bonded to a metal are metal.

  • Today is aluminium and we're gonna take the single simplest carbon containing unit, which is a myth.

  • I'll group C H three.

  • So try me.

  • Ethel Aluminium is actually the world's largest tonnage organa metallic.

  • It's quite hard to get accurate numbers, but it's a least 10,000 tons per year.

  • And you think, Hey, that's a useful compound.

  • It could.

  • We should be out to do some chemistry that both in the lab in an industrial scale.

  • But unfortunately, the compound has one or two problems.

  • Associative.

  • We're going to show you that by attempting to try and weigh out some tri metal aluminium in air.

  • So I've got a syringe here, and we've got it contained within this canister.

  • I'm wearing gloves for reasons that will become fairly obvious.

  • There's gonna be a little bit of faffing around here while we get this opened up in a safe way.

  • I'm filling the syringe full off An inert gas we're using are gone today are gone is completely un reactive.

  • I just turned that sound off, so I flushed the syringe three times With are gone Now, that should mean that we can pick up some try me file aluminium with comparative safety.

  • So we go down into this canister and I'm just gonna take a little bit and then I'm gonna pull this up like so.

  • Now there may be a slight flame as this comes out the end.

  • There it is, Right?

  • So why can't you way out?

  • Try me.

  • Thal Aluminium in air.

  • Well, let's have a look.

  • Here's some in air and as you can see, the compounds spontaneously catching fire as we dump it.

  • And in fact, I've put about two grams of tri metal aluminium there that's burning with about the same energy as a one bar electric fire at about the same rate.

  • And so you've heard the glass crack there.

  • That's the energy coming out of there.

  • So the triumph all aluminium has a very weak carbon toe aluminium bond.

  • The bonds that aluminium forms with oxygen are incredibly strong.

  • So we're getting a massive transfer of me file to a burn flame.

  • And I think if I pick this up, you can see this is now the severely damage.

  • And that's due to the heat that was merely generated by turning all of those weak carbon aluminium bonds into really strong carbon oxygen bonds so you can see a little bit of aluminium oxide left.

  • That's the same as you would find, I guess, in a variety of grinding powders or indeed, in common, Bray zips.

  • It was in the extreme heat when we reached about 500 degrees C.

  • The thermal shock on the ground glass cracked.

  • So I don't know about you viewers today.

  • Whether you'd like to weigh that out in air without special precautions, Here's the compound in air.

  • We're just going to release this slowly.

  • We're going to see a bright yellow flame and oxidation.

  • So going on 1321 Okay, okay, No, try me.

  • The aluminium is actually a critical additive in making the polarization off the monomers that are bound in our modern society.

  • So the next time you pick up a plastic shopping bag or a black refuse sack or a piece of plastic Tupperware.

  • There's a good job that's come from a catalytic process involved one of the other metals in the periodic table detainee, Um, but that will be completely inert until we start to mix in some tri metal aluminium.

  • So it's what is known as a co promoter.

  • So if you encounter poly propylene, you can see that on the back of your recycling thing, you'll see PEOPIE.

  • There's a good chance that that's come out of an aluminium promoted catalyst.

  • Professor, You just showed me what to do.

  • It's like How does industry do with tons and tons of it?

  • Well, you've got to be pretty careful.

  • And you saw that we had a metal canister here.

  • It's sealed.

  • It's under are gone, so you need to pipe this liquid around.

  • You need to build specialist apparatus specialist plants, and they can cost many millions of euros or pounds or dollars whatever you would like to put together.

  • So there's a great lot of this material, but it's remarkably underutilized in many other chemical applications.

  • 543210 We have wanted interior Oriole warn 010 Launch of the first carrier improved Orion to our way after watching, You know, if you see it, there's a release on your screen.

  • So about 10 years ago, we set ourselves the challenge of saying, Can we develop a stabilized version of tri metal aluminium that's able to be worked with by still experience chemist?

  • But not without the rather profound danger that we've already seen.

  • So what, we're going to show you now?

  • So on identical watch glass?

  • Yeah, here's our compound that we developed about 10 years ago.

  • This is now marketed commercially.

  • This try Mitchell Aluminium.

  • So there's the bit we've already seen, and then it's got this die easer by Cyclone 2 to 2 octane add up, and that sucks so much of a mouthful.

  • We just call this compound Dabao because that's much easier to sigh If you remember the flames, you should be worried when I'm gonna take the top off here and I can see a little bit of the fear in your eyes.

  • But if you see here now, well, it's a whole new ballgame.

  • Just by making the ad upped instead of having a liquid, we've got a white powder, it's crystalline, it's free flowing.

  • I'm gonna put a little bit down here cause I kind of don't want my watch glass to crack.

  • But as you can see, even if you are a relatively inexperienced commis, that's much easier to work with now.

  • Although this is kinetically stabilized, it still got all of the potential power to make those very strong aluminium toe oxygen bombs for this one.

  • I'm going to give it a little bit of fuel, so I'm going to cheat by taking a little bit of tissue.

  • This tissue happens to be blue as opposed to your normal white tissue, but I'm gonna move that out the way.

  • So I guess that looks okay about a spoonful.

  • I'm gonna put it on the paper, like so.

  • So again, no major reaction.

  • Thank you down for that.

  • We need to get just the right amount of water in it to initiate directions.

  • I'm just putting a few drops on what I'm hoping is that that will run through the capillary.

  • There you go.

  • So we do get a fire out of it.

  • But I guess you probably could manage with that fire.

  • And it's nowhere near the same horrific quantity of energy you see getting very hot in the middle.

  • So I strongly advise you to not do this on the end of your finger because it would cause severe burns.

  • 321 And I'll be cleaning those line afterwards.

  • So the black suit you can see is actually the carbon that's been produced in the flame process.

  • So we've oxidized up to carbon dioxide.

  • But we also produced a little bit of graphite.

  • That's unusual.

  • Actually.

  • I've not noticed that before, but we don't normally spray the stuff around the lab for obvious safety reasons.

  • Sorry.

  • Yeah.

  • Sold for science.

  • You just have to clean it up this mess.

we never seen it do that before it normally the shatters or it just about holds.
