Aspirin is converted in the body into salicylic acid, this is what actually does the pain killing. Salicylic acid is also what makes large amounts of aspirin toxic. When methyl salicylate is ingested it is metabolized into salicylic acid. Ingesting or applying any of this methyl salicylate to skin in large amounts has the same effect as taking aspirin. It doesn't matter if the starting aspirin is still in the final product, it is itself unsafe. A lethal dose of methyl salicylate is seven grams or so.
This. Accidental ingestion of oil of wintergreen by a child is a very common scenario used in medical education because it is effectively an aspirin overdose and treated the same way. An ingestion of
Those were the days! It's a sad thing to see the "chemical-free" chemistry sets of today. Google the "heirloom chemistry set" - it's a kickstarter project that aims to resurrect the great chemistry sets of yore. I supported it!
I am curious I have a question. I have always heard that pure alcohol can be used to run an engine if you had nothing else not gasoline or other liquid fuel , but it would burn it up and destroy its internal parts,
Oh and I have seen where top fuel racers that have the higher octane engines have used alcohol before thought but because it is closer to the actual fuel in terms of its use,
Dirt outlaw classes Burn alcohol and produce around 800 horsepower on a quarter mile dirt track quarter and half track and hit speeds over 140 mph it burns too well and clean.
1. HCl in a aqueous solution is only as strong as H_3O^+ which I believe has a pka of -1,8 at least I think so, just too lazy to look at wikipedia. And so its a weaker acid than conc H_2SO_4. H_3O^+ could protonate Sulphate to the Hydrogensulfat-Ion but not more. 2. Sulphuric acid has a boiling point above 300° Celsius so you cant destill it 3. MgCl_2 is a soluble salt. You can try running an eletrolysis of soluble sulphate salt but the yields aren't really high.
Ever try using this oil to free stuck bolts? I hear oil of wintergreen is supposed to be great for that. Maybe a little oil of wintergreen vs WD-40 test is in order?
So if I chew an aspirin tablet, why doesn't it taste minty? It's been a while since I had any aspirin, but from my recollection, aspirin have a unique flavor that does not have any minty flavor at all.
Because aspirin is not oil of wintergreen. My aspirin was old and actually smelled like vinegar, produced from its slow decomposition. Refluxing aspirin with methanol, as I did in the video, transforms the aspirin's active ingredient (acetylsalicylic acid) into oil of wintergreen (methyl salicylate). There's no wintergreen in there to begin with - that's the magic of chemistry!
I doubt there would be any measurable amount of aspirin left in the product. The bicarbonate wash would neutralize the remaining sulfuric acid as well as deprotanating the aspirin which then pulls it out of the oil phase.
Thanks the the insight! I know very little about organic chemistry, and this was one of my first explorations into it. I still say to avoid skin contact, since there could be other impurities in there too that could be absorbed. It's a general rule of mine that anything from the lab stays there!
It is drain cleaner, but what does that have to do with anything? It's still concentrated acid, and still quite dangerous. Frankly I'm surprised they sell this stuff to the public. I neutralize it because it's just good practice - you want to remove as much impurity from your product as you can!
The vials? A website called Specialty Bottle. They have good prices and no minimum order quantity! I also like their amber boston round bottles for storing solids.
science Vlog He's not kidding saying HF is highly toxic. It is probably the scariest chemical there is. A tiny exposure can cause no pain at all, but you will be dead in 48 hours. Never mess around with HF or soluble fluorides!
Dissolve might not be the right word. Maybe tiny particles suspended in solution, like a colloid. I'd heard that was possible at one point, but the more I think about it the less likely it seems. It's probably just a dye to make it look more menacing so consumers don't take it too lightly.
frechieguy Like all poisons, the toxicity is in the dose, the tiny amount used in wintergreen candies would be non toxic unless you ate ridiculous amounts. Compare the caffeine content of coffee, in theory it's possible to die from drinking too much coffee, but few people do! (Although there IS concern about caffeine pills and energy drinks)
There is no difference between "natural" and "man-made" chemicals. Methanol is methanol, regardless of whether it came from wood or was synthesized directly from carbon monoxide. Did you know that, in the fragrance industry at least, to be labeled "organic" only the carbons need to be from natural sources? They can do whatever they want synthetically from there. There's nothing inherently bad about "man-made" chemicals. Everything, even water, is a chemical! They are your friends! That all being said, most of my reagents are almost certainly industrially made.
Nope. The binders are insoluble in the methanol, while our target product is. After the reaction you can just filter off the solids and everything you want is in solution.
Yeah it has. I've just had a lot going on lately. I actually tried recording a video yesterday but the lighting was just awful due to bad weather outside. I'll try again when things clear up around here.
idopyrotechnics eBay. Search for graphite crucibles and molds, there's tons of them around. I do still keep tabs on my comments and answer when I can, but yeah video production has slowed down quite a bit. My current project is pretty massive and is taking forever to make something postable out of it!
Ok cool thanks for the info and maybe just make an update video because it's been over half a year weather you say some experiments you've been doing or just try and make a mini project just to make sure you don't lose any subs... But it's glad to see you haven't dropped off the face of the earth 😄
What's with almost no vids l8ly I rember when you use to pose once or twice a week [ I also haven ben on for a few months so.. And there has only Ben a couple vides :( ]
Yeah I tend to post in spurts, and I slow down a lot during winter because the cold sucks away all my energy. I've got a few ideas that I'm working on, and if they pan out I'll get some things up!
It's easier to find than you'd think. As I said in the video, my acid is from a commercial drain opener. It's Liquid Fire brand, from the plumbing section of my hardware store.
The entirety of chemistry is not drugs and bombs. This attitude, even if stated jokingly, is what is slowly destroying amateur chemistry and in fact all of home science exploration. It used to be if you saw a kid outside building something you'd think "wow he's going places!" Now, kids are discouraged from doing anything with the slightest amount of perceived "danger" and are told to just sit and stare at a TV screen. It's a sad trend I'm trying to combat.
what are we doing this for? I got here researching restoring old rubber parts

I really enjoy these. Very concise instructions, good narration, and the fun of chemistry :)
Thank you very much! I'm always worried my videos drone on with excessive narration, but I'm glad you enjoy them :)
IDK if you know this, but the HEET in yellow bottles is IPA. HEET in the red bottle is methanol.
this is the same process as they are using in medical schools to make mint crystals?
Do you know when you'll make another video?
Been busy around here lately. I'm still around though, so new stuff will come eventually!
remember people for a good time drop acid not water.
Nothing says Christmas like finding a brand new deluxe Gilbert chemistry set under the tree.

mrhomescientist That sounds like a great Kickstarter project worthy of our support.
When is your next video coming out mrhomescientist
isin't your product contaminated with methyl acetate .acetylsalicylic acid hydrolysis to Salicylic acid and acetic acid
I am curious I have a question.
I have always heard that pure alcohol can be used to run an engine if you had nothing else not gasoline or other liquid fuel , but it would burn it up and destroy its internal parts,
They tested that on mythbusters I believe, and if I remember right it does work but isn't that great.
Nods Thank You I had thought so but never got to see that episode,

*I like the way you cook.*
Why is the conc h2so4 orange
Great video! Will I get some fairly conc Sulfuric acid by HCl and MgSO4?
1. HCl in a aqueous solution is only as strong as H_3O^+ which I believe has a pka of -1,8 at least I think so, just too lazy to look at wikipedia. And so its a weaker acid than conc H_2SO_4. H_3O^+ could protonate Sulphate to the Hydrogensulfat-Ion but not more.
2. Sulphuric acid has a boiling point above 300° Celsius so you cant destill it
3. MgCl_2 is a soluble salt.
You can try running an eletrolysis of soluble sulphate salt but the yields aren't really high.
You should try Electrolysis of Copper Sulfate
or just go out and buy some AM :P Its cheaper and you get more.
Thats just my 2cents ;)
Where do you get your chemicals and glassware?
Ever try using this oil to free stuck bolts? I hear oil of wintergreen is supposed to be great for that. Maybe a little oil of wintergreen vs WD-40 test is in order?
I hadn't heard of that, that's an interesting idea. Worst case scenario, your bolts would smell great!
Great video. What brand of Sulfuric Acid do you use?
It's Liquid Fire drain opener. I've heard Rooto is the brand of choice for home chemistry, but I have yet to find any!
mrhomescientist
Ace and True Value hardware stores sell Rooto.

8 mL as a catalyst? Isn't that a little extreme?
I doubt there would be any measurable amount of aspirin left in the product. The bicarbonate wash would neutralize the remaining sulfuric acid as well as deprotanating the aspirin which then pulls it out of the oil phase.
Thanks the the insight! I know very little about organic chemistry, and this was one of my first explorations into it. I still say to avoid skin contact, since there could be other impurities in there too that could be absorbed. It's a general rule of mine that anything from the lab stays there!
Yes, I agree with the policy, it is just that the justification wasnt right in this case.
Why would you neutralize the acid. Isn't that just drain cleaner to begin with.
I think it would require an enormous amount of baking soda. Pool ph down might work even better.
It is drain cleaner, but what does that have to do with anything? It's still concentrated acid, and still quite dangerous. Frankly I'm surprised they sell this stuff to the public. I neutralize it because it's just good practice - you want to remove as much impurity from your product as you can!
Where do you get those bottles for chemical storage?
The vials? A website called Specialty Bottle. They have good prices and no minimum order quantity! I also like their amber boston round bottles for storing solids.
Thanks! I've always been at a lack of bottles to store the things I make in.
Are you still making videos
One of these days...
Good because I really enjoy the videos especially the ones deLing with metal keep up the good work
mrhomescientist please come back! we miss you ;_;
He was at a stem camp this week at fsu
+mrhomescientist Why has it been so long? Not that i mind, but i have not seen a youtuber go inactive for so long!
is there a way to make hydrogen fluoride from teflon
Pretty much just heat it to about 250°c. Dont reccomend it though. Highly toxic and corrsive to glass
Zivilyn The Wyrd ok ;)
science Vlog He's not kidding saying HF is highly toxic. It is probably the scariest chemical there is. A tiny exposure can cause no pain at all, but you will be dead in 48 hours. Never mess around with HF or soluble fluorides!
mrhomescientist i heard it can cause cardiac arrest :o ill definitely not make that :\
One of your best videos, nice work
How do they get the carbon to dissolve?
Dissolve might not be the right word. Maybe tiny particles suspended in solution, like a colloid. I'd heard that was possible at one point, but the more I think about it the less likely it seems. It's probably just a dye to make it look more menacing so consumers don't take it too lightly.
How does it smell like?
It's wintergreen - a very minty smell. Wintergreen Lifesavers or other candies use a tiny amount for flavoring.
mrhomescientist Are you sure about that? Oil of Wintergreen is poisonous.
frechieguy Like all poisons, the toxicity is in the dose, the tiny amount used in wintergreen candies would be non toxic unless you ate ridiculous amounts. Compare the caffeine content of coffee, in theory it's possible to die from drinking too much coffee, but few people do! (Although there IS concern about caffeine pills and energy drinks)
Are these natural ingredients, or man made chemicals?
There is no difference between "natural" and "man-made" chemicals. Methanol is methanol, regardless of whether it came from wood or was synthesized directly from carbon monoxide. Did you know that, in the fragrance industry at least, to be labeled "organic" only the carbons need to be from natural sources? They can do whatever they want synthetically from there.

That all being said, most of my reagents are almost certainly industrially made.
Huh, I never knew that lol. Thanks for the info.
It's not important that you remove binders prior to adding the methanol?
Nope. The binders are insoluble in the methanol, while our target product is. After the reaction you can just filter off the solids and everything you want is in solution.
A lot of your experiments are almost directly from the Illustrated guide to Home Chemistry Experiments.
It's been a while since you posted something new?
Yeah it has. I've just had a lot going on lately. I actually tried recording a video yesterday but the lighting was just awful due to bad weather outside. I'll try again when things clear up around here.
Ok I'm glad to at least see that your active :) so I'm going to ask you here, where did you get your crucible and ingot molds?
O and I hope your at least enjoying the lightning :)

If you really want to have pure oil, just make distillation with steam. ;) Anyway, great job!
it is been posted in my birthday
Bought 250g ASA for 8$ lol strangely enough, from a pharmacy supplier
Cool, this guy has nice vids
0:47 ohhhhh.. so that's where cocaine comes from
He jumpcut and threw in cocaine
i tried making esters in school and they ended up smelling like nail polish remover XD
Great !
COME BACK TO LIFE
Such Breaking Bad
Meth
Yeah because everyone has some concentrated sulfuric acid laying around. lol
It's easier to find than you'd think. As I said in the video, my acid is from a commercial drain opener. It's Liquid Fire brand, from the plumbing section of my hardware store.
Looks like he making drugs
Are you making meth, or oil of wintergreen? XD

Methyl doesn't necessarily mean methamphetamine, dumbass.
***** He crushed up asprin, this comment had nothing to do with methinol.
mrhomescientist Btw, i know. i was joking, but you have a good point.
Young Universal First, it's methanol, second yes it did. Did you watch the fucking video? He dissolved the crushed aspirin in methanol!
