FYI: I was just disassembling an old Mitsubishi projection TV and came across this video when I was trying to find out what the fluid was around the lenses, used for optical clarity and heat dissipation, turns out it is 70 percent mono denatured ethylene glycol and 30 percent glycerol/glycerine. Just random info.
I've invested in all steel Keck clamps for the reasons you show. I had the same problem and became frustrated to the point of ordering the steel ones at a time that I was flat broke and really couldn't afford it. Lol!
metal keck clips for anything but alcohol or water disstilations, the plastic ones are abs, the data on its softening temp is well piblished, they became super cheap, and easy to get because of glass bong makers, but for good scientific apparatus, metal wins handa down, also, i prefer glass ball joints to the tapered old world, but thats just me. awesome video, need any custom glass work?
Hey Doug, is it possible to separate ethylene glycol mixed with diethylene glycol? Its in these new type sterno cans as liquid and not a gel. What say you ?
Hello i buyed radiator coolant based on ethylene glycol hoping to make EC of it , in same way someone made PC from Propylene glycol on YT but i found that it's containing some additive and it's Green in colour not Transparent . Help me related it
Polyethylene glycol is becoming popular as a medium with Silica nano particles as a Dilatant (Shear Thickening Fluid) for use in body armor. Will you explain the steps needed to get from Ethylene glycol to Polyethylene glycol to see if it is also an easy home made solution? I would like to get into experimenting at home with body armor designs not involving Kevlar :D
@@Chem-iu5jx Hello, for preparation of Automobile Coolant, I tried mixing liquid silicate with ethylene glycol. Silicate is said to be used as Rust inhibitor in the coolant mixture. To my surprise, the solution gradually become thicker and thicker and finally turned into Jelly. Is there a tip how to use silicate in coolant ? As for other ingredients, I mixed very small portions of Nitrite, Sodium Benzonate and Borate. These chemicals work excellently to protect Metal and Rubber parts from corrosion, scaling and other damage.
Can anyone give me a hint about round bottom flasks ? I have this problem where some of the 24/29 equipment I have has a reasonably thin lip or rim that fits the clips quite well and some of it has a thicker lip or rim and doesn't fit the clips right. Why are those differences and how to go about it ? Are there different clips for the same size (24/29 or 24/40) joints ?
How to breakdown the ethylene glycol? I have engine coolant based on that chemical and need to dispose it properly, We dont have a recycler agent here so just wondering If i can do the disposal myself with the help of chemical expert? Can you please advise.
i have a question: how can it be that there is pure ethylene glycol in there and that the boiling point is 40 degrees. the boiling point of pure ethylene is 197 degrees celcius.
Depends on what kind it is. I used to work as a mechanic and I've seen red, green, orange and blue antifreeze. All for different model vehicles. A lot of people don't know that some models require specific types of antifreeze.

use less silicate, what i suspect is happening is the ethylene glycol is pulling water from the silicate solution, causing the jell. the silicate should be less than 1% in the mixture
@@EdwardTriesToScience Thank you for your advise and input. Do you have any experience in Fuel and Engine Additives ? System Cleaner, Octane Booster, Throttle Body cleaner, injector cleaners etc ? All what I know that all these additives are naphthalene based with a very small % of PiB or PIBA that helps excessive burning of fuel and carbon emission through exhaust.
Hey Doug make a ethylene glycol synthesis video. My 40 year old chemistry degree is a bit rusty having decided to flyer fighter jets over working in lab, and can't scale down the patent information in order to aquire a hobbyist amount. I am looking to aquire around 110 gallons and not looking to spend 5 flipping grand!
Could you carboxylate the ethylene glycol to diethanoic acid? How could you go about doing this without polymerization, if that's possible? I'm really interested in making dialcohols, but can't see an easy way to do so without incurring polymerization with the starting reactant or the intermediates.
Hi first of all great video! I would like to know: 1.-how can you make sure what type of glycol you are extracting by distillation, 2.- the differences between this glycol and polyethylene glycol 600 diacrylate, 3.- what type of products I can extract the most polyethylene glycol 600 diacrylate? Thanks a lot!
+Luis Colorado Polyethylene glycol is the polymer of ethylene glycol. I don't think you can use this like EG, it also has a high boiling point due its larger mass. Maybe you can decompose it with heat and get some chemicals by fractional distillation, but i don't think it's worth it.
Rather probable. It‘ll want to split off water, especially when it‘s mixed with a bit of sulfuric acid. The probability is high tho that you‘ll be getting Dioxane, polyethylene glycol and also crown[18] and other crown compounds.
@@giansieger8687 We are getting really bad odors from the neighbors and got high levels of ethylene oxide in our air quality tests around the house and outdoors, thousands of times over the EPA limit... I'm thinking there are some math labs using antifreeze and it comes from that, but I don't know much about chemistry. We've seen all the usual signs of illegal stuff going on at our neighbors. We don't have dioxane, just ethylene oxide and ethanol, we have a lot of ethanol floating around among other chemicals... it's pretty much the recipe for math that we found in the air around the neighbor's house. We have 5 independent lab tests over a little more than a year with consistently the same chemicals listed. We called the police but they said they couldn't find anything.
@@omsingharjit Just read what temperature the ethylene glycol comes over. You should make it so that you get a boiling point below 100 C and somewhere above 50 C just to be safe. Never get as much vacuum that it will start to boil on its own. It could be done, but then you cannot condense it before it is sucked into your vacuum source. The point is: you dont need as much heat that way, and your product has not been exposed to high heat. Which most of the times results in better product. Refluxing a chemical can chance its properties. Keeping heat low is great. A watertap vacuum can help a lot and it only needs to have a little running water to get it going. It will lower the boiling point. If you want to get fancy get a vacuum regulator and a vacuum pump (old fridge compressor could work, but you will need a watertrap so you dont run water into it). Greetings, Jeff
That strongly depends on the viscosity of the distilled liquid. With methanol or acetone you can fill it even over the joints, but never try this with sulfuruc acid
Found a cheap yard sale pressure cooker and how to make the copper coil in this video. ruclips.net/video/NNq28DDjlA0/видео.html I need the ethylene glycol to paint lumber to weatherize it. Is it cheaper to distill it from antifreeze than to buy it? How much do you get out of a gallon?
You're probably thinking of propylene glycol, not ethylene glycol. Propylene glycol is commonly used in medicine/food, ethylene glycol is highly toxic when consumed, and definitely not in medicine.
06:03 So I was always told to do the opposite right up until I finished my degree in chemistry. The theory behind it is that the coldest liquid is passing the hottest vapour, thus the greatest temperature difference and most effective cooling etc etc, it’s even done this way during reflux. I always thought that the reason no one does it is because you have to get rid of the air in the condenser every time you start, most people are lazy. Was I wrong, is my professor an idiot?
Yes, and yes? You want the output of the condenser to be as cold as possible. And since condensation can dump a lot of heat, you could end up with water too warm to condense everything and get a lot more passthrough if you don't do counterflow.
I'm super late to this party but counter-flow heat exchangers are more efficient. This doesn't go into much detail, but this is a short bit on the website of a company that makes heat exchangers (www.thermex.co.uk/news/blog/605-why-counter-flow-heat-exchangers-are-more-efficient). I would also think you would want a more consistent temperature difference throughout the condenser for thermal shock reasons anyway.
Thank you so very much, helped me a lot understanding the EG technology
Just what I needed, and of course it was made by good 'ole Doug! :)
Very good video to help understand the distillation of EG. Thanks.
Like it.
Very useful and informative. Loved the way you explained things here. Thank you.
This channel is way better than codys lab, ya know, real chemistry, not just dissolving metals in acid
Doug never inhales argon though

Why not use brake fluid?
how about make Polyethylene glycol?
By Giving ethylene glycol so many heat and pressure..
No, it's done by dehydration. Heat, yes, sulfuric acid, for the water removal. But at ambient pressure.
Michael F If you mix ethylen glycol with sulfuic acid, you form 1,4 Dioxan!
You make many products. 1,4 dioxane is only one of them.

I'm really interested in making dialcohols, but can't see an easy way to do so without incurring polymerization with the starting reactant or the intermediates.
You can do an oxidation, to make oxalic (diethanoic) acid. But oxalic acid is pretty cheap and readily available, so it's not needed.
If i use it whith black oil i cant recycling
This is propylene glocol ?
EGDN?
why not)
If you used old used antifreeze, would the product still be good?
It can still be purified, yes. It would not degrade much in storage.
What's the difference between ethylene glycol and polyethylene glycol 600 diacrylate?
Ethylene glycol taste better 😋 * ethylene glycol is poisonous do not try and taste it*
nice video but where you will use it?
Blu Deat It's a good solvent. Also, since it's a diol, you can condense it with carboxylic acids to make polyesters

it's ethylene glycol, not glycerol

How to distill polypropylene glycol?
Heat it, let it pass throuh a condenser, add a boiling chil if it gets too violent. Done.
You should have used vacuum distillation to keep the temperature down.
Then how we can find the pressure vs Temperature chart for different liquids ?

@@omsingharjit There is one rule which works perfect with most substances: when the pressure falls by half, the bp decreases by 15°C. Use it!
Honestly a round bottom should never be filled more than halfway when used as a boiling flask.
That strongly depends on the viscosity of the distilled liquid. With methanol or acetone you can fill it even over the joints, but never try this with sulfuruc acid
