I've learned two things from watching this video. 1) the reason random buttons on ROTC uniforms would be crumbling apart when they came back from the cleaners is because those particular buttons are soluble in TCE 2) if I ever stain something paper-y and I am in an emergency, I can always stop by a local garage and ask them about their brake cleaner
The perc (AKA: Stoddard solvent?) dry cleaning machines actually have distillation units built-in. When the perc is dirty/contaminated, it's filtered and re-distilled for the next clean wash cycle. The rear of the machines are fascinating!..a Rube Goldberg dream!
Currently working on a job site doing groundwater remediation for this stuff. Sodium permanganate injections and an soil vapor extraction system running. The stuff was used for cleaning freshly machined parts.
Looking from the "Outside In" I see how replacing water in the liebig condenser with a low boiling point refrigerant would make it possible to condense very low boiling compounds. So many parameters including atm pressure this is why chemistry is my passion. It's made so many millionaires and this easy automatic future world we live in. Thanks for the video, my curiosity is fulfilled tonight now :)
Not sure if it's still being phased out or not, but this video was posted in 2016, and not too long ago (late 2020) I purchased some of this exact product (with the tetrachloroethylene). I also see it in Walmarts and Home Depots quite frequently.
because of the Cl I thought at first, that its quite inert. but then I remembered that there is a doublebond between the two carbons so maybe you try to reakt it with a halogen(maybe bromine). My 2nd thought was that you could try to polymerize it.
How do you know the impurities are not volatile and will not distill over? I am familiar with trichloroethylene. This was used in factories (in hot pits) to degrease metal parts. Before that, carbon tetrachloride was used for the same purpose. My dad had a fire extinguisher (in a spray can) that used carbon tetrachloride.
Hi, I am planning to make a lava lamp. I like the harmless formula of the liquid with water + salt and more dense lava wax. Do you have any idea to get a denser wax with a stable dyeing capacity but above all without perc? Or maybe a resin formula?
Thank you for showing this educational video. Is TETRACHLOROETHYLENE highly pungent or pungent? Is TETRACHLOROETHYLENE highly flamable or flamable? I want to use TETRACHLOROETHYLENE in my washing machine to dry clean my suit. is it possible? You tried cleaning TETRACHLOROETHYLENE by using that chemistry apparatus. I understand that dry cleaning machine cleans TETRACHLOROETHYLENE by heating it up. So once my washing machine has washed my suit, how would I be able to clean TETRACHLOROETHYLENE? How would I be able to dry my suit after it has been washed in my washing machine using TETRACHLOROETHYLENE? Would really appreciate your help in this matter. Many Thanks
y is an org solvent with such high boil point used in dry cleaning? y not use a lower boiling one eg dcm or acetone so it can evaporate faster after cleaning?
Using the brown glass is a good idea; since UV will break down the carbontet into small amounts of phosgene. I believe the same happens with chloroform.
god I hope they don't ban it. It works so well on car parts, it evaporates so much quicker and cleaner than stupid acetone. Just bbSHSSSSSSAWWSS and its just instantly clean and dry in 5 seconds.
Ya I didn't realize how toxic it is at first, I just got off the phone with the AAPCC actually. What process do you need to go through to make it. It's not something I'd try, I haven't got access to any equipment, I'm just curious.
This solvent soaking isn't at all _cleaning_ . It is just going to spread the oil evenly through the paper so you don't have spots, but the paper is still contaminated.
I used to have a local dry cleaner do this for years in my neighborhood, but they were so bad they would dump this chemical behind the site known as the Marinwood Plaza shopping center, and it is still contaminated into the soil and nearby water wells of a dairy farm. They then went bankrupt. And this is why my family no longer gets their clothes clean at dry cleaners as it is an environmental concern.
Just FYI whatever you do, do not spill this stuff on the ground. PCE and its dechlorination products are VERY persistant and pose a chronic exposure risk to every house downhill of you for thousands of feet if even a few gallons of this stuff is spilled and it costs tens of thousands to hundreds of thousands of dollars to clean up.
As far as I know "per" means 4. For example, perchloroethylene is ethylene with 4 chlorine atoms, which in case of ethylene is all hydrogens being replaced by chlorines.
This per- prefix in hydrogen peroxide means something different. It signifies the presence of a peroxide bond (oxygen to oxygen), like in persulfate where a peroxide group bridges the two sulfur atoms. The per- prefix in permanganate or perchlorate means they are the most oxygenated compounds of manganese and chlorine respectively. The per- prefix Doug is talking about indeed means that all the hydrogens from a parent compound have been substituted by a halogen. This is no longer recommended by IUPAC by the way.
i assume you will be reacting it with spam. also i watch because chemistry is interesting. but i am almost completely ignorant as to the use of most chemicals :)
You, chemplayer, and NileRed are all I ever watch any more on youtube. I appreciate the quality of your videos Doug. Makes me feel very nostalgic for my organic chemistry classes and my own lab at home. Just moved into a new house and I have the perfect area for building a new lab. Hopefully by the spring it'll be up and running. I do need to find a solution for heating (Michigan winters are brutal) and cooling in the summer. The area is insulated (storage room off of my garage, brick, insulation in the walls, and insulated windows) but it's not heated or air conditioned. I need to find a heat source that's lab safe...that and building the fume hood are my two biggest projects at the moment.
Gonzalo Boneu True, true. He's gotten a little boring lately though, for me. His videos are great and he really knows his stuff, just a personal preference, so nothing against him.

Hmm... cats are sensitive to water... hooray! Now I know how to properly clean my kitty cat! Thank you, Doug!
It is suspected of causing cancer, i would keep it off the cat
Shazzkid, he's being sarcastic
Except that it's not carcinogenic.

Stoddard solvent is petroleum distillate, aka mineral spirits, chiefly hexane. Not anything like perc.
Excellent! Liked the pace and precision. And thanks J H for posting gallon container info.

They still sell it in Michigan.
For how long, I don't know but I'm stocking up now.
Brake parts cleaner will never be phased out.
It's weird that they've done away with the CFC propellant in a can that's basically full of a chlorinated hydrocarbon anyway.
edgeeffect well no one said that people are smart just that they try to be.
But tetrachloroethylene has no fluorine, so it’s not a CFC... it’s ozone depletion potential is only 0.005.
Your videos are brilliant, the part at the beginning makes them even better.

Amazing, one video that actually explain it for the wondering customer! (yet I tried washing my sofa lining at home before watching this anyway)
its been 3 years ... im starting to wonder if youre ok , Doug.
I think he's dead, Jim. :(
@@mannys9130 don't kid around really ?
Love your videos, very concise and informative.
I really like the direction you took this video.
Those teasers of yours are brilliant, too! I'm really on my toes for the *spoiler* synthesis!
Love your videos as always!

Still in use today. 😁👍
I watch this because I am not good at chemistry
You said in the video that u would use it on another video , did you do a follow up ?
Nice demonstration! :) I didn't know it's so easy to get.
because of the Cl I thought at first, that its quite inert. but then I remembered that there is a doublebond between the two carbons so maybe you try to reakt it with a halogen(maybe bromine). My 2nd thought was that you could try to polymerize it.
+JBFFSK18 Like polytetrafluoroethylene (Teflon)? Perhaps this could be a cheaper not quite as resistant alternative?
It's actually quite inert and does not polymerise
That's all well and good, but what if you do your homework in sharpie?
which country are you living in?
I recognize the ULine catalogue but what is the catalog next to it?
Looks like the percholoroethylene destroyed the red pigment in the note paper, however.
How do you know the impurities are not volatile and will not distill over?
I am familiar with trichloroethylene. This was used in factories (in hot pits) to degrease metal parts. Before that, carbon tetrachloride was used for the same purpose. My dad had a fire extinguisher (in a spray can) that used carbon tetrachloride.
Could this polymerize like tetrafluoroethylene?
Nope
Where do you buy your amber bottles ?
Could you bromate or idodate this compound? If curious as to those variants properties in relation to the original

Anybody knows tetrachloroethylene production plant suppliers? Kindly advise.
If Tetrachloroethylene is heated with some aluminum powder, will it form aluminum chloride?
Nice Doug. Since this is now a few years old, have you had any evidence of peroxide formation in your TCE?
Where we get tetrachloroethylene in Hyderabad....
If Tetrachloroethylene is heated with some aluminum powder, will it form aluminum chloride?
Is this even possible?
Could you please do another video on this same thing but with supercritical co2 instead.
Good brother

S hussein Tetrachloroethylene is pretty toxic. You should just take it to your local dry cleaners.
Here is the answer ruclips.net/video/jP5yVCjehvI/видео.html
It's not toxic.
y is an org solvent with such high boil point used in dry cleaning? y not use a lower boiling one eg dcm or acetone so it can evaporate faster after cleaning?
oh man why didnt u go to hollywood? still loved that part of the video xDD
Could this solvent be used instead of tetrachloromethane for free-radical chlorinations?
+Fezziiwig Chlorine would probably react very quickly with the double bond. As would any free-radical intermediates.
what is difrence hydrocarbon solvant& perc solvant
I'm going to guess hexachloroethane is the next step for this stuff. Although where to from there, I am not sure.
Can it be broken down into CH2Cl2? Unfortunately I can't get DCM here in Europe...
DCM can be distilled from certain paint strippers, so you may be able to take that roundabout method.
CRC Lectra Motive electric parts cleaner has the same ingredients as well.
I have a large drum of Tetrachloroethylene, i'm using it as a degreaser in generators and motors.
So how does this deodorize or clean dirt?
probably a stupid question but whats chickenintin? a acronym for something? great videos doug hope you come back to youtube
I thought it was a chicken that plays NES. XD
Some people using it to dissolve red loctite, but I can't get this stuff in the UK 😒
The first time I listened about perc was in Ghostwriter (PBS 1993)
Same here.
It was that contaminated waste on from old drycleaner's disposed drums episode right?
@@yegfreethinker Yes, that time when the kids had a community garden.
I tried removing ink from a shirt using this but did not work at all
Chlorinated brake cleaner works so much better than the new tree hugging stuff.
are you going to mix it with carbon monoxide ..and make that fun smelling party favorite?
I've been to many weddings, but none where they're serving chili. ;)
Using the brown glass is a good idea; since UV will break down the carbontet into small amounts of phosgene. I believe the same happens with chloroform.
This is not Carbon Tetrachloride. It's Tetrachloroethylene. Though it's still a good idea to store it in a brown bottle.
if u use something oil is soluble in 4 drycleaning, y not use dcm? dcm has lower bp than perc
god I hope they don't ban it. It works so well on car parts, it evaporates so much quicker and cleaner than stupid acetone. Just bbSHSSSSSSAWWSS and its just instantly clean and dry in 5 seconds.
Maybe a Diels Alder reaction? With that as the dienophile? I have no idea lol just guessing
Let me guess: 1,1,1,2,2,3,3-heptachloropropane by reacting it with chloroform in presence of aluminium chloride. Great videos BTW!
1:22 AKA buy the stuff that doesn't clean brakes for shit.
Would if be possible for you to make dimethylmercury?
Yes, it's surprisingly easy to make. I don't think I would do it though. It's incredibly toxic.
Ya I didn't realize how toxic it is at first, I just got off the phone with the AAPCC actually. What process do you need to go through to make it. It's not something I'd try, I haven't got access to any equipment, I'm just curious.
+Samuel Filler
It is easily made using methyl iodide and sodium amalgam.
+Doug's Lab Incredibly toxic is a bit of an underestimate don't you think?
+TheTechnic Lord it's like saying that volcano over there is a bit hot. :)

Very nice, but how to remove tetrachlorethylene from the washed material? it is very sticky, oily and won't dry out by itself
It's volatile
