Alcohol Comparison - Methanol vs Ethanol vs Isopropanol
HTML-код
- Опубликовано: 6 окт 2024
- Which alcohol burns better, faster, brighter? I'm comparing methanol, ethanol (grain alcohol) and isopropanol (rubbing alcohol) to see which has a faster rate of combustion, which burns brighter and which is the best choice for an alcohol stove. A good look at the difference between ethanol and methanol and isopropyl alcohol and a good time with methanol fire, ethanol fire and isopropanol fire! Loads of good information and a great comparison of methanol vs ethanol vs isopropyl alcohol! Thanks for watching!

When your trying to learn about fuel and accidentally find a pyromaniac
An underrated pyromaniac at that
i guess Im asking the wrong place but does anyone know of a trick to log back into an instagram account?
I was stupid lost the account password. I appreciate any tips you can offer me
@Jakob Connor instablaster =)
@Louis Bronson I really appreciate your reply. I got to the site thru google and Im trying it out now.
Takes quite some time so I will get back to you later with my results.
@Louis Bronson It worked and I actually got access to my account again. I'm so happy!
Thanks so much you saved my account :D
This video actually saved my family. Thank you very much! We bought ethyl alcohol from an online supplier and the container was properly labeled and it was cheap so I tested it and the flame was as blue as the ocean. No laughing matter as I know someone who went permanently blind from methanol poisoning after continuous use of 'rubbing alcohol' that he thought was safe.
This happened middle of 2020 when the pandemic was in full swing.
How did that happen?
Wow! Usually if any methanol has been added to ethanol, it is labeled as “denatured alcohol” indicating the presence of methanol or other stabilizers. This kind of fuel should not be used for any consumption or for cooking over. Pure ethanol is a better option! So glad this video helped!! Thanks for watching!
Yo like I do my own distilling and the higher the proof of ethonal the more blue the flame is. And methanol makes a yellowish flame. Much more carbon and nasty components that are poisonous
@@jamesthomas8481 The proof matters. If you add water to ethanol lowering the proof, the flame goes more blue believe it or not. Is your alcohol lower than 190 proof? I have food grade/un-denatured alcohol for tincture making, it's 190% proof (95% alcohol by volume) it burns with blue and yellow flames like in the video, lots of yellow when the lights are out.
I dilute it for tinctures of-course...it's grain alcohol.
I was trying to find out which one of those alcohols evaporated quicker but instead found this channel. I’m not complaining because it seems like I just found an amazing channel. Very underrated. Hope to see you grow in the future onto the spotlight you deserve!
Thank you so much! I appreciate the support!!
Please make a video with doing a flame test with different types of hand sanitizers. They put methanol in some sanitizers labeled as ethanol. Some sanitizers are also just labeled as 'alcohol.'
Just skip to 2.35 and watch till bout 6.15. Or from 4.45 - 6.15 for a more abbreviated version that still gets you the answer. Incredible that he was able to add enough fluff to make a 10 min video out of this.
Idk why but the intro got me 😂😂😂😂😂😂😂
Same
Because I now know the brightness means more soot particles glowing while they're being released, that means isopropanol would leave the most soot at bottom of your kettle, and methanol would leave the least. Maybe that's why the "alcohol for burning" (as labeled) that I have here at home is methanol. Though I use it exclusively to clean sticky things.
Nice video man. Seems like an interesting channel too (but try and shorten the intro a bit!)
the fire aspect of alcohols is interesting.
another aspect to learn more about is how they compare in being distilled.
especially given there is usually some water in the mix.
for many chemistry experiments alcohol is used to dissolve some material.
like a certain plant. now legal to grow in more states than ever before.
and later , after some reflux, and filtering the alcohol, the filtrate
can be distilled to recover the solvent and re-cycle it.
plan on paying 20-25 dollars a liter for ethanol or methanol. costly .
so its sensible to learn how to recover the stuff for re-use.
have you covered this topic already ? let us know so we all won't
have to search
Good video but I felt the background music was too loud.
Comparing it to acetone would be interesting.
Two questions from the nosebleed seats here. 1) Pretty simple: if I wanted to use a lantern mantle on an alcohol reservoir (stove) to make an area light, which should I use? The mantle should increase combustion toward complete by providing a superheated surface, but is that the whole story? Heat of combustion 5.8, 6.4, 8.0 kcal/kg. Flash points 12, 12.5, 11.7 C, autoignition 464, 363, 399 C. The raw data says IPA for max light. Safety factor of Ethanol starts to play. But the nearly complete combustion in open air makes methanol very attractive since the mantle irradiates visible light as long as it gets hot enough. But with a pressurized carburator IPA jumps back to the lead. SO, you have the parameters of the experiment---- GO!
2) Turbocharged internal combustion engine using alcohol injection as post intercooler charge air cooler: which alcohol and what ABV to use for best performance in gasoline carburetor (blow through), gasoline MPI, gasoline DI, diesel. Hopefully I just started a flame war (pun intended), and I can sit here an watch.
I love chemistry from childhood and getting into a lab with a genius chemist and trying out experiments is really on my bucket list🤓
Thanks... I just made a home whisky and it smelt funny but after watching this and running all the tests as well as other tests it seems I'm safe its just the flavour of the grains I used...
Also this video explains why people prefer using ethanol for cannabis extracts rather than using isopropyl 🤷🏻♂️
You need to distill and reve the first 5% of distillate as a small amount of methanol is present in wines, beers, whiskies. Otherwise a harmful amount of methanol is present. Go to tech ingredients channel to explain further.
I do my own distilling and I never get that yellow flame in my 70% ethonal...always a blue solid flame
Fun fact most of the alcohol actually have the same drunk effect on your brain, the difference is that almost all of the alcohol would kill you before you even get drunk
Your video just taught me a lot
Great comparison demo sir.
However ethanol is used as fuel n it burns as Luminous.
But it is considered safe for drinking as opposed to methanol . Little confusing jussojuan
Lol, great work. Since the stone age man has loved fire.
Nice vid. Subbed. Interesting stuff, excellent content delivery.
Something people need to be aware of - flame color alone cannot differentiate between the alcohols, there are more factors that need to be taken into account.
Just because it was blue does not immediately indicate it is methanol. For example, 50% ethanol burns with a blue flame at room temperature. Heat the liquid and it will burn with an orange flame. The airflow of the container will also change how visible/invisible the flame is depending on the air/fuel ratio.
I don't disagree with anything in the video and you offer a great comparison but I feel like people are extrapolating the wrong conclusions from the video.
The fire looks like a silhouette of a person dancing. I think its pretty
I can see that
Dear Science Pirate, Do to circumstances out of my immediate control I am van living in Grand Rapids, MI and need to know how to build an inexpensive, safe can heater/ stove. Do you have such a video?
GREAT useful video, but 2 mins of intro is a bit excessive.
So with ethanol not giving off toxic byproducts, is it safe to say you can cook directly over an ethyl flame? I realize how that sounds.. but just wanted to make sure before I take my 95% grain alcohol camping.
I know this is a bit late but for anybody out there wondering this, yes, ethanol is safe. I used to take isopropyl camping to use on my alcohol stove, but the smell of the fumes made it clear that I needed to keep the lid on my pot at all times. Ethanol burns much cleaner and you can tell there’s not a bunch of extra soot and unburnt residue
why not see what temperature it burns at? You only look at burn time.
he's the white Morgan Freeman
Definitely subbing, this channel is a good idea.
Made a tin can infrared heater courtesy of Robert Murray-Smiths channel and currently all I can get for alcohol fuels is 91% rubbing alcohol. I have a gallon of methanol on order and I'm hoping it burns slower.
At half of a normal tim can full of rubbing alcohol i am getting 40 mins burn time, in his video he claims less than 1/4 filled can of methanol will burn for 1 1/2 hours so here I am trying to see if methanol does burn that much slower and if soo that would help me from redilling my heater every 45 mins or so.
What alcohol is the best for fuel?
Isopropyl or ethanol?
i watched a video on how bio diesel is made,they used methanol
Best effective hand sanitizer isopropyl 75% based or ethanol 80% based. And if same Alcohol content then which is best.
So ethanol can be used for fireplace inserts?
Thanks for sharing knowledge about alcohol.
Awesome...you answered my question. Ethanol it is!
Think I'll subscribe and see what comes next.
How does a gel situation change this? Trapping the vaper? What's the longest burning gel? Not for light but heating quicking but longer? The rate of little oxygen enough to burn but w/ burn of the fuel? + the environment around it. Does that not matter?
Thanks for sharing. I’m building a gasifier for our community for heating, hot water, steam, running generators and making storable syngas using waste wood and trash. This link shows the lower.
In your experience, what would be the most balanced alcohol between heating power, cleanliness and efficiency to use in mountain stoves that use liquid fuel? I have read that the colder the color of the flame, the more heat it offers. Thank you so much.
Yes, the more blue the flame the cleaner the burn. I have found that at room temperature, 80% ethanol is the best. Ethanol evaporates with the water, and the water limits how fast it evaporates. If you use 95% ethanol, the ethanol will evaporate too fast and you will end up with a rich air/fuel mixture (and give you a yellow flame) and if it is too lean (50% ethanol) you would have a clean flame (blue) but it'd be difficult igniting it and a lot of the ethanol would stay trapped in the liquid. Therefore the best composition is highly dependent on temperature - if you go to a higher elevation I would consider 95% ethanol. Do not use 100% ethanol, these are potentially more dangerous (and expensive).
Can i defer methanol from ethanol based on ther flame color?
This is what I want to figure out. From the looks of it ethanol is more luminous vs mehtanol.
Defer is not the same as differentiate
Nope
Using boric acid
I just found out that windshield washer fluid has methanol in it, and it being pretty toxic, I thought I would look into making my own fluid. I would prefer to use ethanol, but I would be way overpaying due to the extra tax.
Watched to consider a fireplace insert fuel. By the way. Can you add in safety note on denatured versus what is safe to drink?
I can smell residual from everclear burning and hope it is safe in a large room?
Maybe add in a specific review of fireplace inserts. I'd tired of stinking wood.
You have contaminants/additives which is causing the different degrees of yellowm they all burn blue.
I am not entirely convinced here, methanol burns yellow, ethanol burns clear.. but does react with the atmosphere, so will have a yellow tinge on the outside.
Your ethanol burned yellow?
Hi, i would like to ask, is there a more correct way and easier to test for methanol content in liquor?
Jay Amplayo liquor meant for human consumption should have no methanol as methanol is toxic
@@blackilluzionz That's probably why he wants to test for it.
@@blackilluzionz it could make you blind or cause permanent facial paralysis or death 💀
Burn time and flame size is invalid testing when comparing these fuels if you don't state the fuel percentages.
There's no fire department in Hell. Nor are there any fire extinguishers down there. Ice cubes & air conditioners're forbidden & it never snows. There's no frost in December. The number 1 hit songs are "It'll Be A Hot Time In The Old Town, Tonight & Come On, Baby, Light My Fire". People are "all fired up".
Should have mentioned the btu value for the amounts burned? did the Methanol produce more or less btu even though it burned for a shorter period of time?.
There doesn't seem to be much difference between ethanol and methanol as a fuel: both clean burning but in the UK Methanol is much cheaper. Right now burning Methanol in my decorative small home burner of the kind protected by tough glass. Gives out a remarkable amount of heat by convection presumably. It takes 200ml which burns both fuels for about 55 minutes at a useful level. All the talk about toxic methanol is related to industrial exposure. Just wash your hands if you spill any. On the other hand ethanol is safest on skin as it is used in common hand cleansers. I'll use Methanol as it is cheaper.
Love your video man. Very good lesson too.
how do you test methanol and ethanol content in beer? I am a little curious as to why they call this covid-19 The coronavirus? Maybe there is too much ethanol or methanol in the beer and the f.d.a. does not regulate what we are legally allowed to put into our body????
So, which one(s) would be safe to use for disinfecting my hands? I know isopropyl alcohol should work just fine for that but I can't find how to make that online quite as easily as I can find methanol and ethanol.
Ethanol is the main ingredient in the vast majority of commercially available hand sanitizers!
@@TheSciencePirate
Awesome thank you!
According to hand sanitizer recalls recently, methanol is toxic as hell. Seizures, coma, blindness, death. Dont use that
@@rebeccapq1725 The risks are mainly associated with consumption. A little in hand sanitiser (3-6%) isn't going to kill you. It's in it to deter you from drinking it.
This is the first time I see a real human being, that I think belongs in the One Piece anime instead of real life.
The Science Pirate = Doctor Hiriluk.
Hi! I found a lot of liquor from various brands and the price is very cheap. i.e $17 for Blck Lbl. So how to distinguish ethanol and methanol from liquour?
i thought that ethanol flames was more transparent and methanol was more yellow.
Everyone talks about carbon monoxide poisoning from alcohol heaters. Indoors, is that an issue?
Great presentation!
I recently purchased online what they claimed to be Ethanol 70% (meant for hand sanitizing hands) but it hardly has any odor. Could it be fake?
I'm just afraid it's methanol instead, which very toxic for the body.
Great videos, Which alcohol would I burn to produce the most carbon dioxode?
Would denatured be good for a distillation setup
Octain , petrol, desel fuel video pls.. Burning up
Can you turn up the music please?
For a second I could almost hear you and it was ruining the tasty jams
When I burned methanol it burned bright yellow to orange….when I burned what I believe is vodka it burned blue & not as high as the methanol
So is it safe to drink dilute ethanol 99% diluted to 40%
Could I use isopropyl alcohol in my indoor ethanol fireplace?
I hate to be a critic because I liked the video but honestly, it took 2 minutes to actually start the video. The intro is just too long. Great editing skills btw.
thank you ...
What is best zippo fule alternative 🤔?
which one evaporates faster?
is methanol safe to burn indoors? I want to use it for ventless fireplace instead of ethanol.
Great question Ingace recently purchased 20 litres and intend on doing just that. It's dangerous if inhaled a vapour or ingested or absorbed through skin as it acidifies the blood. However if burning properly apparently leaves C02 and Water vapour with a few other mi or by products. As long as it's burned and not left to evaporate I'd say my research shows it safe...
Thank you ya man .
Please we some videos for what's to making that three cohol. We want knowed what's the different for contacting.
Hi, just curious, can we use commercially available isopropyl alcohol in zippo lighters?
Isopropyl alcohol is too volatile and would be a disappointment as zippo fuel. :(
Have you ever been Dr. Spock for Halloween ?
If the color of the flame is almost blue, 95% blue, can you tell me what kind of alcohol I just burned?
Most likely methanol
Where did you buy 200 proof grain alcohol?
i been messin' round with this for years. use the denatured alchohol labled 'alchohol fuel". go make urself a stove fron an aluminum bottlecan, fun stuff! make urself a snuffer for emergency! (just use a soup can).
Oh subbed!!
Good show 👍
AWESOME!!!
Sooo if I wanted to use one in a performance vehicle for an intake injection setup to bring down intake air temps which will give the biggest atmospheric temp drop in the intake? And for a forced induction setup would it be better to inject pre intercooler or post intercooler?
Methanol and water injection its used for that.
@@mihaiilie8808 Yea, and if you've ever been anywhere near a car that runs on Methanol it burns your eyes like crazy.
why can you drink ethanol, but not methanol? They are both alcohols. I wonder.
Methanol and you're first blind and then dead in a few minutes!
Is methanol used for disinfecting?
i ofcourse wouldent like to try it but really curius dose the "Drunk" vary from diffrent alcohals? like the "high" from synthetic cannabis similer but also diffrent how dose the effect of other alcohals have on the "Drunk" before poisioning or death?
Can you please list the materials used and the method
If I squint, bounce my head and stutter my cadence will that make me sound more intelligent?
I'm probably going to install a meth injection system on my car soon. And my friend said I could also use IPA, looks like he was right. Thanks for the informative video.
Isn’t methanol invisible?
What amount of fuel did you use in the timed comparison? Thanks
I believe it was 5 mL of each alcohol for the timed test.
2:16 to get in to burning
My ethanol doesnt look like this at all, it has completly light blue flame that almost florescecess. This might be pure hmm its all gone gone.
@The Science Pirate Hi, new to the channel. Just subscribed. Question. I know some people burn Ultra Low Sulfur Diesel in their kerosene heaters but in order to make it work they have to add some sort of additive and they also add Isopropyl Alcohol. Supposedly it keeps the wick from getting clogged up, makes it burn hotter, and keeps the smell down. I don't know how true any of that is but there's a bunch of videos on YT of ppl burning ULSD in their kerosene heaters because it is much cheaper to buy than 1K kerosene. Anyways, I have a kerosene heater but I don't burn diesel in it, I just use straight 1K kerosene. However, I was wondering, is it ok to add alcohol to kerosene? Would there be a similar benefit of keeping your wick cleaner and/or make it smell less, or burn hotter etc? If so, which alcohol would be best suited for this purpose and how much alcohol would you add to a gallon of kerosene? It's ok if you have no idea what I'm talking about lol. Thanks!
I wish I could provide better insight for you, but I have very little experience with kerosene heaters. My father-in-law burns diesel in his, but he doesn’t add anything to the diesel. I think his heater is rated for either type of fuel. Maybe someone else can provide some better knowledge?!
@@TheSciencePirate No worries, I found a great site (although I don't have it bookmarked on this laptop) that goes into great depth explaining all things kerosene heater related. In the end, I wound up finding a place that sells kerosene for about the same price as the low sulfur diesel. Unrelated, are you an actual chemist? I mean like academically speaking, do you have a chemistry degree? I tried asking a question to the guy that runs the "Chemical Force" RUclips channel but didn't get a reply. Had a question about "SIO2 ceramic" coatings for automobiles which is like the newest craze for "waxing" your car. If you're not familiar it is basically a clear liquid that you apply in a similar way as traditional paste type wax but it lasts in some cases years as opposed to the old carnuba type wax that only lasts for maybe a few months at most.
I do have a master’s degree in chemistry education! The SiO2 waxes form a ceramic-like coating instead of a waxy coating. The silicates (or silicon dioxide) forms a strong coating that is extremely protective!
@@TheSciencePirate he meant to say thank you.........
Thx sir help me for project
Anybody know the name of the song that played in this video? The first song?
Any more vids on the irony of inefficient burn = more radiation
Love methanol blue flame but it just doesn't perform as well as ethanol in vehicles.
You can mix methanol with water before injection. This on a vehicle that may have a high IAT performs WAYYYY better than e85.
aqua ctrl totally wrong for direct injection engines carbon build up on valves is really common so using water methanol injection will clean the valves bring intake air temps down and increase octane a lot I personally run methanol in my Subaru and it’s saved me money on maintenance cost that others that don’t run meth have to do(walnut shell blasting the valves)
Who lied to you? Lol methanol works wonders in cars
@@4door_papi "AS WELL". Ethanol has a higher energy density, you get better milleage.
Know why alcohol burns in my channel, in hindi.
Isopropanol? Is this different than isopropyl?
They’re the same!
My Gentleman Jack tastes weird ... so I burned it, flame is blue, hopefully it's not methanol. If I go blind, then sue on my behalf.
I’m trying to create a handheld torch using alcohol. Would I have different results using 70%, 91%, 100% rubbing alcohol?
70% will evaporate more quickly.
Actually 100% would evaporate more quickly. The more water it contains, the slower it’s evaporation rate.
@@TheSciencePirate Oh yeah. I got it messed up somehow.
Torch as in blow torch? Historically self pressurising ones used petrol (gasoline, benzin) or methylated spirit (ethanol, spiritus). I would choose methylated spirit over petrol for safety, it is less volatile.
help!! Can you differentiate between the types of alcohol based on the smell of the liquid?? and how accurate is finding what kind of alcohol is by its flame color ??
like it! But please tell the kids at home never to drink in lab.
Cool!
