字幕表 動画を再生する 英語字幕をプリント 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.
