Big question: Is a Graham condenser useless? In order to find out, we do some fractional distillation of fuel and talk about what the major component of each fraction is (or at least have a guess at it) and nothing blows up which is nice, but I do insult the condenser and swear quite a bit sorry Music from Aphex Twin soundcloud dump: 27 leaving home-bradley
this is one crazy bong dude
hahahahah always love seeing the original comments in this section
i mean distillation apparatus is a bong?
damn, thats even above louis ck on the comedy scale
@SinisterMinister ah fuck off you sook
@SinisterMinister oh wow so glad you were here to point out that someone made a joke that was easy to make, I applaud your intelligence good sir good job good job epic have some reddit gold
@Pax go back to your "cringe" subreddit, you're pathetic lol
Don't knock it, I've made some good bongs out of glassware
"when i got that random illegal shipment of glassware accidentally sent to me" haha what
@jayson0987 Yeah, this also piqued my curiosity... Maybe it was some kind of LSD making type of glassware? I really don't know...
If that's the case, I didn't know that some glassware could be illegal.
All I can say is fuck the world we live in if glassware can be illegal.
@Cameron McColl It may have been imported in an illegal fashion, rather than being illegal in and of itself.
In Australia glassware and specially distillation equiptment is restricted over a specific volume or diameter. There could easily be other restrictions in the glorious nanny state
@John Smith yeah. Technically not allowed to have a flask bigger than 5L. You need a permit.
The Graham condenser was invented by Prof. Thomas Graham, who was working for British Revenue. Liquors were taxed according to their alcohol content. Traditional methods for determining alcohol content were not accurate. So Graham made this condenser in order to precisely determine the alcohol content of a liquor.
Still useless, he should have invented the hydrometer instead.
@TissuePaper that only measures density. Add more sugar and it becomes more dense, and therefore, not accurate.
Little known fact
He also invented the Graham cracker.
Much more versatile than his single-app condenser, as it can be made into a tasty pie crust as well.
@Dr. M. H. -- Ummm, that honor belongs to Nabisco (the National Biscuit Company). ;)
@Kevin Byrne LIES!!!!!
😆
Edit: thanks for the trivia I so love. Never knew Nabisco is an abbreviation.
The shadows on the corrugated iron background give this a very unsettling film noir vibe, maybe I should film these videos from the other direction, so the background is roses. There'll be more going on and possibly more distracting, but it wont give you vertigo at least
@The Terrible Animator I didn't notice either... He underestimates how awesome his videos are, nobody is looking at the damn wall in the background... lol
Reminds me of the 1987 Max Headroom television pirate incident
It is that dodgy Indonesian petrol we get in SA. Loads of butane
I want to just mention. Be it regular or Premium. It contains Ethanol. A very easy way to ensure that the Ethonol DOESN'T absorb water and end up damage your pressure washer, weedwhacker and lawnmower. Largest glass jar or container you can find. Poor the old gas. Then add 1/4 to 1/2 distill water. The H20 will bind to the Ethanol (obviously don't drink), use a siphon for the top layer, that will be the pure gasoline without the ethanol. What would intresting would be to find out what other chemicals/organicis/volatiles are bound to the water and ethanol. (Here stateside we litterally have to find places that sell non-ethonol gas.)
No mate, film them in B&W to amp the film noir vibe
Aviation fuel is full of bloody lead I saw a vid with project farm put it in a mower engine and it left metallic lead beads above the piston.
@Cole H i do!
🚬
@burajirujinn TEL me more, buraji!!
🤭
@TissuePaper Bullshit - water soluble mercury compounds just fuck your kidneys a bit before you piss them out. The lipophilic organomercury compounds are where it's at.
@Vidmantas Bieliūnas I did forget about the fat soluble compounds, those are pretty bad too.
TissuePaper in your defence, those compounds need to be water soluble to be so dangerous.
I thought its purpose was to evacuate the inner spiral and backfill with an inert gas, then apply high voltage. Fill the jacket with fluorescent dye for more visual effects. :P
Ah see now I have a use for it again!
Yep. Improvise a Geissler tube.
Tried that, coating borosilicate glass for neon lamp is difficult.
LOL
@joesexpack Please elaborate on this!
Your videos are getting funnier. Loving the rambling commentary at the moment.
I have a parallel adapter useful for vertical distillations so can do without the horizontal liebig. I think that grahams potentially have a decent heat transfer rate with all that surface area and a vertical orientation can mean a smaller bench footprint. I have used them for larger volume solvent recovery - set it up and crank up the heat while you do something else with the benchspace. (Washing up perhaps.)
I have the exact same thermocouple too. My glass thermometers get a lot less use these days.
I'm glad you liked the rambling, I was concerned this video was a little too full of random anecdotes, which turned what should have been a kid of simple video into one of my longest ever made..
I guess they do have a decent transfer rate, but I don't like the smaller footprint thing. It's not that much smaller, and means that your outlet is closer to the heating source... there's no way i'd put the fumes from the petrol distillation that close to the heating mantle, so that also limits its usefulness to me. So yeah, you actually use yours by choice? Maybe they aren't deserving of a 1/10 on the rating scale, that was a little harsh.
In terms of the thermometer, yeah they are real good. I'd say I use the glass thermometers probably 2/3 times still, but when it comes to a video, I prefer to use the screen because its so much easier to see whats going on without having to focus on a tiny line of mercury
I don't think petrol contains compounds with boiling points above 160°C. What I think happened during the boiling process is that you accidently created a whole bunch of polymerisation reactions (Diels Alder mechanism and other types of cycloadditions). These polymerisation products would be yellowish-brownish and would explain why the last factions were coloured. I'm not sure the dye moved at all, many dyes have quite a high boiling point so the last flask probably contained a mixture of dye and polimerisation products. Maybe you could make a follow-up about this topic? And keep up the good work, your videos are really fun to watch.
Given what they're watching it would make sense
Petrol for vehicle use contains some decane if it's about 85-90 RON. There's traces of it in higher RON rated fuels. The only "petrol" I know of that really has almost none is Av-Gas. Decane has a boiling point above 170C.
@Gordon Lawrence Winter blends of gasoline might also be very decane-deficient - they're skewed towards the lighter components for easier starting in low temps.
@Billy Mays you bet yer ass, boy!
🤓super-nerd😎
@Billy Mays We all are, that's why we're watching chemistry videos.
7:34 camera moves down the column to the roundbottom flask
stirring bar: weeee
0:19 Illegal glassware? Is there such a thing?
@Save Nigeria even a highball?
@Jules supertramp there's a big diff between self defense and cooking meth, homie.
If you're not cooking drugs with it, I doubt the police would ever find out someone had it and wouldn't likely enforce the law if they did know u had lab glassware.
@J H lol when i was in gradschool, a pharmacy station (where they mix IV bags and prep other meds) at our uni hospital exploded. The pharm-tech was cooking meth.
Remember kids, ether is very explosive.
@Dr. M. H. can you make meth or an explosive in a highball?
@Dr. M. H. Hahaha... Touche.
14:06 he caused the fires in Australia
You should distill crude oil and make a video of it! Thats what I would like to see (and may try myself).
It'd be really dirty and blocks glassware...really light north sea crude might work in glassware.
@Gerry Murphy Oh really? I wanted to give this a shot on my own as a nice intro to fractional distillation. I'll be sure to look for the thinner north sea crude oil when I do then. Thanks!
@J H You could also try making your own version of the columns they use industrially. The way I'd try to replicate it would be to get a bunch of disposable pie tins from the grocery store, and use a nail to punch holes in from the bottom (creating a lip which, hopefully, would prevent the liquids flowing out of the trays they belong in), and then stack those on top of each other over a boiling vessel and wrap the whole thing in foil.
Ghetto for sure, but it would keep you from plugging up your expensive glassware.
@TissuePaper hey, thats a cool idea. That would be a continuous distillation setup too!
Straight and gay alkanes, I love it lol.
Trans & cis jokes work too. 😋
Whats the deal with your "k" lol they look like the capital "R"
cursive k
Never seen a lower case k lol?
I wouldn't be without my Graham condenser for alcohol distillation, and being just alcohol I made the connections out of plumbing parts
Talking about tetraethyl lead for some reason reminded me of this time when I was in grade 2 or 3, the principal said some older kids were seen breathing exhaust from the exhaust pipes of cars. I don't even know what would possess somebody to do such a thing.
4:07 have you thought about heating it up and modifying the glass? Make it something more useful...
Distillation of petrol.. what an absolute legend
Welcome to this weeks edition of "Why is this in my recommended?"
How about distilling motor oil?
The bongs I could make from your glass pieces is actually nutty 😂👍
Chris Primmer lol McGuyver’s we are, i love the one film where the guys like, bring me...... then they were like we dont have ... he was like ok then bring me ..................
20:49 For flaming gay kanes!
This <90° thing is for transferring something from a Schlenk tube to a flask under anerobic conditions.
Schlenk
I saw the movie. It was funny. :)
@Billy Mays shlonk
Could you run your lawnmower if you put all of it back into one jar and mixed it?
I would have to think so.
I'm Graham, and I approve of this condenser!
"Hi, today we're going to boil some gasoline in my backyard"
I knew there was something fishy about those alkanes.....
woah wait you were working with something YELLOW?
are you alright?
"Because it's dark" The horrors we've seen Australia house is only the first wave. The next comes out at night.
I was almost going to buy a graem condenser before I watched this
Cheers for warning me mate
Unfortunately I already did
I HAVE BEEN WAITING SO LONG TO SEE THIS ON YOUTUBE!!! You da chemist boi ;)
I love your retort stand / lab jack.... it looks strangely like an old stool.
You, uh. You did pump the coolant from the bottom up. Right?
You'll probably appreciate the Graham condenser the first time you make methyl iodide or methyl formate. The former is especially stubborn to condense.
ah the memories when you just pulled up to the pump and the clerk would ask you leaded or unleaded!!
I can remember them asking for regular or premium, there was no unleaded fuel, except for Coleman stoves and lanterns, and gas was less than a dollar a gallon...
3:05 In my reactions I only use them
God, finally a chemist with a sense of humor. I Lmao throughout the whole video, the way you explain things is great. I definitely sub'd
US has ethanol in motor fuels routinely, and methyl t-butyl ether.
While you’re right that Grahams don’t get a lot of use I love using mine for steam distillations. Something alchemical about it.
Interesting video!

How is the thermite series?
kan petyim haha it’s going just not at the moment due to the cold. I see e+f and I have the exact opposite problem :)
The Gayest Person on YouTube yea it's summer here, infact it's around 34 c. The weather is great for evaporating solvents, bad for storing low boiling point solvents though the push in cap of my dcm shoots out everytime I open it.
Crack some heavy oil next time, I want to see the fireball :D
I love how I get an ad for petroleum dyes on this vid
Love it!
I recently read a bit about the burning properties of organic compounds. :D Hydrocarbons tend to produce more soot when burned the longer they are. So, it might not all be due to double bonds. It would be interesting to do some more tests on the fractions, like treating it with baeyers reagent or bromine water.
Too bad. Nevertheless, it's still a result that shows, why it's so difficult to separate all the different compounds by distillation.
Yes it would show that pretty well. Or maybe I'm wrong! An experiment is a lot more meaningful than my armchair assumptions!
I've been thinking it might be good to try and get something useful from this experiement, probably the hexane? I could distil just the hexane fraction, clean it from alkenes, then re-distll? Could be a useful lab solvent
I'd try washing the fraction containing the hexane with bromine water until it doesn't lose it's colour anymore, then with some sulfite/thiosulfate/metabilsulfite solution to remove excess bromine. Otherwise it might react in sunlight with the alkanes. Drying and redistilling it might remove the halogenated alkenes that might have a way different boling point. A beilstein test might reveal, if the product contains any halogenated compounds. Sounds like an interesting project to me! :) You could even just collect the fraction around 68°C from some petrol, treat it like I said before and use the rest for your car :D
I drive a diesel car so maybe just the high boiling stuff :P
I was thinking I could sulfonate it with sulfuric acid, then wash all that out with water. Maybe there's some sulfur stuff in there too, perhaps the acid wash should take care of that too.
Bromine isn't something that that's easy to do for me. I mean I can, but yeah
This might also work. You only have to take care that the sulfonation isn't reversed, when the water mixes with excess sulfuric acid. I don't think you'd need large amounts of bromine. The small scale experiment about bromine I uploaded a while ago might be sufficient and you wouldn't have to deal with lots of nasty, horrible smelling fumes. I'm curious if any of this methods might really work on extracting hexane.
Funny enough I remember by mom and dog walking into the garage when I had some tube pumping the sulfuric gas outside during a distillation and she and the dog stepped on the tube which caused my still head to pop off and spray boiling acidic fumes in the whole garage. Ah memories... Always keep a gas mask on hand.
I only use the Graham condenser with ethanol distillation because I have it and need to justify owning it.
2:23It sort of rounds this corner - this made me laugh stupidly hard cuz their was nothing their
Could you do this with an oil and get some volatiles from it? Make your own petrol from oil?
MMT additives, if I remember correctly, leave a reddish deposit on spark plugs. Might be a good identifier...
neigbours think doin shake n bake haha
