Don't panic. Years ago tetrachlorometane (called "tetra") was easy to buy and I used it to produce smoke grenades. I smell it many times and I'm still alive.
@adboshop, I'm pretty sure it's bad for the ozone in the air, and the liquid is bad for us. Although, I'm sure eventually it'll get you. More like firefighters, then pyrotechnics, or am chemistry.
that short arc is throwing everything from UVA to UVC into the mix UV also breaks C-Cl bonds sometimes, so you are likely getting a bit of C2Cl6 as a byproduct

It's in case the UA-cam algorithms get after you, then you leave a smoke cloud to throw them off your scent. If that doesn't work, the you can offer them same-day dry-cleaning.
Back in the 1970s when CCl4 wasn't banned yet and I was a curious kid getting into chemistry, I found a bottle of it in my father's tool cabinet - he was using it as a degreaser. I used quite a bit of it as a solvent for various experiments, and in the process yes I did smell it, and indeed it smells sweet. Also 50 years later, I'm not dead yet. At least I don't think I am.
I just need to say, you are one of my favorite chemists! I really enjoyed this educational, learned lots about my favorite subject, chemistry. Keep educating people, there are millions of people in the scientific community that respect your videos and appreciate what you do, great explanations!!
The borosilicate glass passes some UV, but the higher UVB and the UVC spectrum parts are blocked by it, much in the same way the cut away glass from the lamp blocks UV. Easy to use, low voltage lamps to put into a reaction vessel are those 12v 3w UVC lamps you can find from China. Those need to be run from a 15-25v AC power supply with a resistor or choke in series to keep current at 250-300mA. They will run on DC, but with lower life span and light output. You can get them with or without a wavelength filter. Those without generate a TON of ozone because of the UVC light tearing aparth the oxigen molecules, pretty badass. They are small enough to fit into certain large sizes of test tubes.
For at least 30 years, we used Carbon Tet for cleaning printed circuit boards. Must have used gallons of the stuff with no precautions whatever- and yet here I still am at nearly 70...
Me too. I used it at college for the same purpose, and when I worked at a cable company, we used loads of it to clean rubber deposits off of the insulation moulding and testing machines. Everyone just considered it another basic solvent, like acetone or isopropanol. One day a girl dropped a whole 2 gallon flask of it on the floor of the lab, and it dissolved all the so-called chemically resistant floor tiles over quite a large area. That was fun. A lot of things are technically poisonous or carcinogenic in large doses or with chronic exposure. Take petroleum for example…
well. take an .1% odd of getting any particular cancer and multiply it by 300, or 400. Oh but thats per year. Your multiplying it every year until you pass away, instead of multiplying by your age to estimate your cancer risk.
Use an ozone producing UV pencil lamp from a crappy phone sanitizer. Irradiated in a Cl2 atmosphere under mild reflux. These lights also make a decent water sterilization device too.❤
Such interesting reactions. I really liked this one. I’ve made chloroform before but never tried CCl4. Looks like if the phosgene doesn’t get you the UV will end up cooking your eye lenses (cataracts).
A few pointers if you are to do this again(i know you likely know a good portion of this already!): I probably would have flushed the setup with either argon or nitrogen before adding the chlorine/UV - this would mostly eliminate any chances of a significant level of phosgene being produced. Combined with perhaps having the UV light source either inside the glassware itself or using fused quartz glassware(would be expensive, i know!). The inert gas flush would have eliminated any oxygen and having either fused quartz glassware or having the UV source inside the glassware would have allowed for maximum UV exposure to the reagents - as typical sodium borosilicate glass absorbs a good portion of the shorter wavelength UV needed for this reaction to occur. A possible alternative to the xenon tube btw would have been a mercury vapour discharge germicidal tube or heck even UVB/UVC LED's! Those are much more efficient(and somewhat safer) alternatives to the xenon light...due to the high operating temperatures of xenon tubes, they have a tendency to literally explode if you get oils/grease (this could come from your skin even) on the exposed quartz tube, the outer glass envelope is not only there for the UV filtering but to prevent this possibility from happening.
Huh! So... since you're so comfortable with this, think you might show us how to make EMS (ethyl methanesulfonate)? I enjoy mutation breeding plants and would like it if my main tool might be a bit more readily available.
"you can just leave the chlorine gas and chloroform in the sunlight and it should work" My brother in christ I do not want to die of two poison gasses at the same time
The UV light can't pass trogh glass only trough quarz glass. That is very unefficient method, the bulb should be inside or setup should be from quarz glass. But in any case congrat for good work.
There’s a few already on yt. It’s a pretty boring series of reactions really… I mean, if you have seen a single nitration, watch that 2 more times and you’ll get the idea.
Instead of a vanilla tri nitration, I propose a more fun challenge. Nitration of ALL 6 carbons. It’s not technically impossible. If he was able to make at least 1 molecule, it would probably be a first :D
When I was a kid my dad had an old bottle of typewriter cleaner and it had carbon tet in it and I opened the bottle and took a big wiff and it hurt my nose
A single whiff isn't gonna wreck the shop lol... they used to put it in fire extinguishers... by the pound, all to be released in the air. Not good... but wasn't an instant issue to use one, and probably would take rather regular exposure to it to have the long term issues. Phosgene? Yeah. Can't be emphasized enough. Don't play around. CCl4? I wouldn't recommend any aromatherapy with it, but sampling the odor? Pfft. Might as well be something everyday like gasoline... extensive exposure not recommended there either but we all get a sample of it fairly regularly without issue.
Distill the stuff and measure the yield. Also, making phosgene by oxidizing the carbon tetrachloride with fuming sulfuric acid woud be something cool to see that no one has ever shown before on youtube. Collect it with a cold trap and seal it under pressure in an ampoule. Don't use latex rubber tubing as it will just eat through it.
Do you really think a spoonful of CTC will make a difference when millions of tones of the stuff was used previously as a degreaser, solvent, fire extinguisher, dry cleaning agent etc?
@@alexrogers777 the same could be said about the "small, but still negative" impact your comment makes in contributing to CO2 emissions from the electrical energy you used.
you could have just used a mercury vapor lamp (lots were used in street lights and can be found for dirt cheap) and you can just break the outer glass then rub alcohol (liquor will do) on the internal tube before powering it on and usually they wont explode
Listen, this video is incredible and i will definitely be recreating it to make my own carbon tet. BUT, for the love of god dude, i spent $35 max for a 250ml pressure equalizing addition funnel. I can see you spent about as much on the video so WHY would you make so much chlorine in such a jank dangerous way? Please spend just a bit more money on your safety
Don't show this video to all those people on amazon trying to buy carbon tet to clean their pans (yes I'm serious they buy anything that sounds like CTC and then get mad).
Brother, how can we extract oxytocin from rye? I heard that this hormone can affect people's emotions and make a philandering person become sincere. Have you ever thought about making oxytocin?
Well, now looking back on this, I feel you at this time; 2am. However, if I relax and stop trying to interpret each word immediately (as spoken) it’s a lot easier to understand. It’s just my natural instinct to do the opposite because of adhd antics which I believe is what you may be describing.
I don't understand why you are so afraid of this solvent. It is regularly used in our laboratories. Just follow basic safety precautions. CCl4 LD50 has approximately 200 mg/kg, and the maximum permissible concentration is 20 mg/m3. It is not such a dangerous substance. I'm sorry for the mistakes, I used a translator.

They were wearing a welding face shield, most likely to protect eyes from the UV light, not a "full hazard suit".
