Distilling Mercury Metal

- UPDATE: It was brought to my attention a much much better way to store it. The mercury should be put in the bottle without adding water. The bottle is then stored in a bag full of sulfur. Storing it under water will inevitably lead to it becoming all gross again.
Okay, I am finally posting the mercury distillation video. This was obviously dangerous to do, so please don't try to repeat what you see here!

Most of us played with as a kid in school. Elemental mercury is not likely to do much unless you have wounds and even then it is not as risky as folks scream about. There are compounds of mercury that will kill the shit out of you with even one drop on your hand. Not elemental mercury though. The danger comes from water soluble compounds and ones with an attached methyl group, compounds like mercuric chloride or the massively scary dimethylmercury. Though breathing any metal fumes to include mercury is super bad juju.

RIP lol
I'm reminded of the researcher who accidentally spilt 1 or 2 drops of soluble mercury on her gloved hands, and her balance coordination, speech, and memory all deteriorated over the next few months before she ultimately passed away. It was so sad, like she knew she was going to die, and leave her family behind, but she was powerless to stop it. And, the hero that she is, she dedicated her few remaining days to educating others on the proper handling of soluble mercury, so no one else would suffer her same fate. Her name was Karen Wetterhahn, and she was exposed to dimethylmercury.
She will never be forgotten to me, thank you for educating me on this
The really tragic part of that case is she followed the safety practices of the time to complete accuracy. The standards were just flat out wrong about how long it would take dimethylmercury to penetrate latex gloves -- i.e., about 15 seconds. It's not like she was being sloppy or careless with safety.
That's organomercury. Very different than elemental mercury. The major risk here are RCRA regulations and emissions violations (captured on camera).
@@tz4601 Breakthrough data for organometallics is not rare to find. The only thing that is rare is breakthrough data for leached material that experiences a phase change (aka the metal component becomes a gas temporarily before condensing back to a liquid). In the case of organometallic mercury, the breakthrough studies are very well understood. This is why "silvershield" type gloves exist.
It’s only mercury bro
I wish I’d had the internet 30 years ago. I worked for a spotwelding company that had these old, large electronic glass tubes filled with mercury. I broke them open and collected 35 pounds worth, put it in a plastic coffee container and stored it on the floor in the basement. A couple years later I noticed the plastic had cracked, and about 20 lbs worth was missing. It either evaporated or spilled between the foundation and house wall into the soil. Now I know it was pretty stupid and I’m lucky I wasnt seriously poisoned
You should let the EPA know so that the current owner can have it remediated. That is incredibly dangerous. Wow.
@@petragris1947 Bit late after 30 years
@@archkull Someone lives in that home, and it may still be contaminated.
@@archkull the irresponsibility you're displaying is too typical of 2022. Sad you clearly don't care about the only planet you have to live on enough to call poison control.
_I wish I’d had the internet 30 years ago_ well, the wonders of American education, innit? I did not have internet thirty years ago, yet well over forty years back I learned (was taught) about the dangers of mercury, back in my 7th or 8th grade of primary school (chemistry classes). And for a good reason - it was the time when mercury filled "body temperature" thermometers were in wide use (no other fancy gizmos!), and every now and then some of it cracked (by accident) spilling its content inside people's houses.
But this is not to poke fun at whatever system or an individual, and there are TWO very simple and effective remedies for dealing with small mercury spills.
Yeah, I know - 20 lbs (9 kg, or 0.7 l/ 22.5 fl oz) IS NOT a small spill, but anyway most of it has evaporated by now - so NOW it is "small", and the very first step (kinda irrelevant now) is to gather back as much of spilled mercury as you can. Then try to locate the bigger cracks where it may heave seeped into (UV light may be of help - check "Looking at Mercury Vapour - Periodic Table of Videos" ruclips.net/video/7ZT7xqwk84E/видео.html
And then - and this is most important and relevant NOW part - sprinkle the entire floor there with either aluminium powder, or (better still) finely powdered elemental sulphur (that would be "sulfur" in US).
Spread it all over, use the broom to "push it" to and fro all over the place, so it could get into all cracks and crevices in the floor. Sulphur reacts with mercury at room temperature forming non-volatile mercury sulphide, which is still kinda "unhealthy" but won't do you any harm if left untouched (unlike elemental mercury).
Aluminium powder works in a similar fashion by forming somewhat non-volatile Al - Hg amalgamate, but then the aluminium becomes prone to further oxidation - so this "trapping"of mercury may not last long (see "Aluminum and Mercury" by Nile Red - ruclips.net/video/IrdYueB9pY4/видео.html).
"Gonna boil some mercury"
K
"Oh also put some glass in it"
Wat
"It helps it boil"
Gotta remember that for some spaghetti
the glass functions as boiling stones and reduces the amount of flash boiling
It's actually really interesting. I make sweet tea a lot (I'm from the south) and to make the tea, I always heat up water in the microwave to boiling. I usually use old glass measuring cup, but we got some brand new pyrex stuff. I put it in the microwave, and it wasn't boiling, so I put it in the microwave longer, and it still wasn't boiling, so I took it out, and the shock of it hitting the counter caused it to boil violently. The reason is, is that there was nowhere for bubbles to start to form on the new glass.

@@rubywest5166 yeah of course but you are still here commenting. 😆
More beautiful than expected! The vapor pressure of mercury at room temp is in the range of 10^-6 atm so I wouldn't expect any mercury to have visibly gone into the trap. I think the remaining mercury was shiny because the mercurous oxide decomposes at a fairly low temperature. Also can you tell me why you didn't distill to completion? I know in normal distillations with water, but I cant think of any contaminants that would cross over here. My distillation apparatus is steel and I cannot see inside so I always heat it until the temperature rises above the boiling point of mercury, at which point I know its done. Should I not do that?
Hi Cody!
Good to see you got verified!
Whoa its Cody on nilereds video.
Probably worried about overheating the flask and cracking it.

"so how did you get mercury poisoning?"
"I was distilling my own mercury"
"why"
"I thought it would be cool"
Godspeed you magnificent bastard
Mercury poisoning is terrifying.
@Public Commenter comes from the middle English 'God spede you' which means 'God prosper you' ie 'have a prosperous journey' or 'I hope you prosper'
mercury vapor is the main reason people actually get poisoned.
absorption of liquid mercury metal is very low even through skin and intestines. excessive prolonged contact will still eventually poison someone though.
you cant see the vapor which is why its considered highly toxic and a bit exaggerated to the extent you might get the (dont even look at it or your dead) vibe.

I'm glad you finally did the distillation. Partly because I'm curious, and partly because there's no other way I'd ever see this happen.

Ooh! Have you tried making vermilion (mercuric sulphide)?

Thank you for informing the viewer of the steps you took to make it safer, most youtube videos omit or play down the risks asociated with using dangerous chemicals
I love your channel so much I give a thumb up to every video to remember which of them I've already seen.
Cody sends his regards. Great video. I will say, your safety measures for handling mercury is refreshing. Cody himself seems incredibly lax about it. I'm sure he knows what he's doing out in his middle of nowhere, but still, I'd probably handle mercury like you do here.
Now that you have distilled your quicksliver, you are pure of heart.

I love the way the Mercury beads bounce (at 11:48+) inside the distillation tube. Great video, thanks.
I had a small amount of mercury covered with water in a small glass container. When I wanted to remove the water I placed the container of mercury in my freezer, waited for the water to freeze and then removed the ice.
One day in my hometown, there was a Hg spill in a gymnasium. Consequently, the school in where the gymnasium is situated had to close until the Hg is wiped to the bone.
Mercury vapor + elaborate glassware + lots of heat? Whooo! Sounds like a fun afternoon!

i sure will watch this again in years time

hey hey hey
10:50 what mercury sees when I stare at it distilling at 5 am
When I went to school they had a huge open tub of mercury that we used to make barometers. We were allowed to play with it and submerge our hands in it without any ventilation or safety equipment.
Cody'sLab did that on youtube
It's probably not super dangerous
My thesis advisor told me in the days of Mercury based diffusion pumps it was common practice to use depleted Uranium chunks as boiling chips to suppress the boiling issues you encountered when cleaning the Hg. Wow hot Mercury and DU in the same process. God bless diffusion pump oil.
8:37 Why can't they make solvent containers that don't dribble down the side every single time you try to pour some?
I know fluid dynamics is hard, but come on!
Salvatore Shiggerino ^rt
Hes simply doing it too quick - the angle is too shallow for the remaining amount of i-PrOH in that bottle.
The usual "dribble" u might be talking about is due to surface tension. Since the container is not made up of a super hydrophobic (and oleophobic) material, the liquid will stick to it and not seperate right away.
However... there is no such coating. These pictures or videos of repelling coatings are useless... rub your finger over that area once and the coating is gone. There is also no cheap material. But even if u pay the VERY high price for FEP (a polymer like PTFE) bottles... u get the downside of the large diffusion area. But at least you can pour everything (droples all come out) out of there with no spilling. ;)
it's called surface tension bro. Take a stirring rod and hold it as you would to prevent water or alcohol from dribbling but hold it nearly horizontal so that the tip goes underneath the spout. Or, just use a clean pipette to pull it out.
Its so you waste tons of it and you have to buy more (you could always use a glass rod to guide the liquid)
Nile you are the best. This was super interesting to watch, albeit dangerous (which makes it even more fun because my butt isn't at sake). Seriously though, thanks for this great video. I specially like your videos about Hg
That was really neat, I have done a vacuum distillation. I have used a rotovap, which is very similar, but this was really neat.
Great video, as always. Oh and I like when things heat up in your videos.
How do you get your glassware so shiny after using it over and over in "dirty reactions" again?

thanks!!
If you turned the lights off you will see blue glowing as it drips down the condensor. Mercury exhibits a wierd triboluminescent effect when very pure abd in a reduced presdure atmosphere ❤
This video really reminds me of the old origins of chemistry. I feel like this is about as "classic" as it gets as I could imagine crude mercury distillations with nearly the same process in a less refined form going back hundreds, maybe thousands of years depending on what culture you look at. ( In particular I'm reminded of how Chinese myth treats mercury and what some emperors supposedly did in order to refine it. ) For me it really straddled that line of philosophical question of "What is magic anyway?" So I'd say you're spot on with the "because it looks cool". Sometimes I wish I could work in a chem lab and this is definitely one of those times but I don't think I could do it as regularly as you do. Especially because I'm not near so careful.
“You can see my house”

@ 1:42 I thought you set your boiling flask in a frickin pie... My brain might be telling me to sleep, but what does it know... MORE SCIENCE!
Good idea with your secondary collection flask. I've wrecked some flasks using high heat, but I found that using a clean hot sand bath (if you have a high flame source) worked out (so far).

Amazing! Simply baffling! In my recommendations was this video and one below, a song by queen(from Freddy mercury)
Great video Nile! Love it when they show up in my feed.
Was wondering what vacuum pump you're using here?
Mercury to me always stresses how weird chemistry is. I'm an undergraduate in it, I know the stuff that happens in most of your vids, but especially your cleaning series is showing how strange a world we are living in.
It was a very dangerous thing to do and I'm glad nothing happened (good thing you did this outside), but you should've removed the water. Before distilling, you can just push mercury through cotton filter. It will absorb any liquid surface contaminants and you'll get a shiny metal happily bouncing in the beaker. No oil to burn in the distilling flask, no water vapor lingering around.
Few more advices:
- a plastic tub isn't a barrier against hot mercury; steel trough would be ok
- cushion all of your vessels; glass ones like to snap with mercury inside bumping on contact with hard surfaces
- store mercury in a steel or plastic bottle - less chance of breaking; that storage bottle of yours has a high chance of just losing it lid; mercury is notorious for this awful trick
And you shouldn't add water on top of clean mercury. If you're gonna cap it, that's it, it won't leak the vapors out and you can put it in a bag with some sulfur which will stay yellow if everything seals. Water is useful to lower the rate of evaporation and can be used in some uncovered applications, but in a sealed vessel, it's gonna build up again.
Only extremely pure Hg will be ok around pure water. If there's even a bit of contamination, it will make the water murky and cover the metal with gunk, so you created the conditions for another cleaning in the future.
Yeah, you are right about everything you said. Thanks for the tips! The mercury will probably get muddled over time again. I will do what you said and store it in a bad with sulfur at the bottom.
Doesn't the mercury oxide (main contaminant) reduce under the distillation conditions? I think this would explain why your remaining mercury is so shiny.
Im planning to go into chemistry during my second year of highschool, and I've decided that if i ever need to study, i will use this channel and definitely introduce the teacher to it.
I blew my Chemistry teacher's mind when I showed him the liquid carbon dioxide video.
Great video! the mercury that was cleaned looked really good!
Thanks!
I really enjoy your videos and watch some of them two or three times!
I never distilled mercury but my impromptu method was to use a funnel with filter paper with a pinhole in it.
The crap would stick to the paper and the mercury is much cleaner looking but obviously not as pure as distilled mercury.
He actually did that in one or maybe both of the two videos where he made mercury.
You deserve much more subs!!
thanks!
so glad codyslab mentioned this vid
Excellent overview of the safety aspects of this. All to often this is assumed and the unwary ( those with enough knowledge to be dangerous ) get caught.
I am immensely impressed that you did this and your nervous system is still intact. A testament to your chemistry expertise.
Oh! Yesss.

Remember: Karen Wetterhahn (October 16, 1948 - June 8, 1997), also known as Karen Wetterhahn Jennette, was an American professor of chemistry at Dartmouth College, New Hampshire, who specialized in toxic metal exposure.

Make liquid hydrogen. It would be truly fascinating but I understand that you probably don't have everything you need to do it.
Liquid helium is much much better but it’s extremely difficult to make because of the extremely low freezing point. It would be even cooler to see superfluid helium

hey brother where do you get your hg? it took me 6 months to hunt down 1lb and it cost just short of a pound of flesh lol.
I seem to recall that a Japanese emperor (can't remember his name) was so obsessed with mercury, that he had an underground cavern built, in which was a landscape of all the rivers of Japan, - all filled with mercury! He also had an apothecarian make up some balls of mercury mixed with clay, which he regularly consumed because he believed it to have magical life-giving properties. I'm pretty sure he died young!
That was probably Qin Shi Huang, the first Emperor of China. High levels of mercury were in fact detected in the soil around his tomb, which is the main reason why they haven’t tried to open it.
hello just wanted to thank you for your work and say that this makes me able to take dumps that im usually not available to
Knowing this is your dads garage, it’s hard to believe how well it could be ventilated
just a thought: you might want to do a blood test to check you Hg levels. as a scientific inquiry.
pre experiment (ideally, though not necessary since normal serum Hg levels are undetectable) and post experiment just to determine whether or not your safe guards were sufficient. i'm sure they were good enough to avoid exposure, but still, if it were me, i'd be curious.
great vid, as always man
Rxist Prepps he may just use a couple hairs and liquid chromatography, that is cheap and can detect low concentrations.
Rxist Prepps Cody from Cody's Lab did that after playing with really big amounts of Hg and even putting his arm half way in it. His levels were not even close to exceeding the normal range.
Colin Ries I saw the one where Cody for tested. The other real problem is that all the tiny amounts of HG that escape into the environment collect and build up.
I was genuinely considering it. Mercury thiocyanate, mercury fulminate, mercuric chloride, mercury distillation...eating tuna... I probably have a nice mercury collection in my body
NileRed nice that you list eating tuna after listing all the chemicals... I don't imagine it would play a big role compared to the other stuff haha. BTW, what about a "extract mercury from tuna" video :P
Could you explain more about how the broken glass would help?
you feed the boiling mercury broken glass to calm it down so it will be less hungry and wont eat your glass container
When you boil something, it's good to give it a rough surface area. The rough surface provides a place for gas to nucleate. It prevents you from creating a superheated liquid as you raise the temperature to the boiling point. Superheated liquid mercury would have the potential to flash to a boil, and that would surely be a bad time for all involved.
I tried watching you to fall asleep and ended up watching like 20 of your videos
Around 3:00, you weigh the two capped jars of mercury with the mass of the jars, water, etc. included and estimate the volume/mass of mercury by that. You then combined both mercury sources into a 1 L beaker and decant almost all of the water. That may have been a much better opportunity to weigh the mercury before distillation, because you can easily tare off the mass of the 1 L beaker ... the only thing left at that point is pre-distilled mercury and about 50 mL (or ~50 g +/- impurities) of water. You can do the same post-distillation and get a more accurate % yield.
You should have calculated the volume by multiplying the radius of the bottle squared with pi and the height of the mercury. Would have been really precise
When preparing, I did that as well, to confirm it was close.
While it’s expensive, fluorocarbon grease is very high temperature resistant and extremely chemically and vacuum stable. Krytox should do a great job sealing this apparatus if I’m not mistaken.
I was thinking Teflon tape; similar stuff.
As a novice, what function does the ice trap provide? Does this cold zone help with the distillation pressure or is this purely to freeze anything toxic that makes its way into the trap?
I visited Cusco Peru quite a few years back , one of the sites on the tour was gold mining , after they mix the Mercury with the gold they will take the amalgam and filter it in a piece of silk , most of the Mercury will pass through the silk and the gold with some of the Mercury got caught in the silk as a nugget , then they will put it into a furnace and burn off the Mercury .

I meant i was implicitly telling you guys to not try it yourself. You are right though, the actual warning was explicit.
Surprised you didn't go with a cheap supplied air respirator, or a proper Hg filtering respirator.
and would washing the glassware with the dirty mercury work to collect all the tiny droplets?

I hoped I caught that with an edit before anyone saw....
Using some mercury to get the last drops isnt a bad idea at all.
