How to make Glycerine (Glycerol)

[@theCodyReeder]

how did it taste? ;)

[@nunchuck90]

Funny seeing you here

[@fishyfish8490]

Cody'sLab Oh, hey Cody.

[@dreamyrhodes]

It should taste sweet

[@acceptthetruthitwillsetyou2598]

cody try this experiment with isopropyl alcohol and explain what happens something strange for sure, not sure if it made soap, fats, etc would make for an interesting video. Also you could use the glycerin for a deep eutectic solution for solar panels or what have you

[@benjaminlarson6168]

should taste sweet, but I don't actually recommend tasting nitroglycerin.

[@Headshotted718]

The person who requested it is probably going to be revisiting the nitric and sulfuric acid video's soon...

[@langberg1337]

Headshotted718 what happens?

[@Headshotted718]

Nitric acid and sulfuric acid and glycerine creates nitroglycerine :)

[@Hobypyrocom]

Headshotted718 :) if your talking about me then i have already made nitroglycerine in the past (like 10 years ago) but not using the sulphuric - nitric acid mix, i was using ammonium nitrate and sulphuric acid... i have made nitric acid in the past too but since potassium nitrate is hard to get here (and other nitrates even harder) i dont use it for making nitric acid in experiments where i can replace the nitric acid with other things...

[@Headshotted718]

Well, if you're the one who requesting the video, then yes, I would be referring to you, lol. And by the way, you can get glycerine at most stores, like CVS or any store like that. And that's not a bad idea, I never thought of that. But for nitric acid, it doesnt have to be potassium nitrate, just any nitrate salt. Would it have made a difference to make nitric acid using the ammonium nitrate? Theoretically, it would be equally as consumptive of the nitrate if you converted it to acid first.

[@Hobypyrocom]

Headshotted718 glycerine here is available in all drug stores for really low price like $0.5US for 100ml. theoretically yes ammonium nitrate can be used to make nitric acid as all other nitrates but its not that simple... in this case you have ammonia ion not rare metal ion so the procedure should be quite different and you need way better equipment and NH4NO3 is not that good to work with... we had one forum (x-inventions) back in 1998-2001 where we talked about this but it seems even the highly skilled and experienced chemists were not sure that it can be done at all... i was trying several different ways back then but all my experiments was fails... even if you get the procedure right i bet its way too difficult to obtain pure nitric acid, i bet that it will be less than 50% so... i love to see chemists make all the ingredients for experiment thats why i was asking for the video :) imagine, you make your own glycerine, you concentrate your own sulfuric acid from car battery, you make your own nitric acid and you make nitroglycerine :) thats what i was doing and i bet thats what will keep peoples interested...

How is this helpful other than the fact its interesting? Like other than amusement, what's the point? A liter bottle of 100% pure glycerine is like $10 at the grocery store in the cosmetics section, his yield was like 23ml... like.. how helpful is it really?

[@danhat1473]

Had to laugh, at 0:32. This came up in my recommended, after watching some biodiesel making vids. And you basically say, (it's not what he says, yes I know): "I'm making biodiesel, but i'm keeping the stuff everyone throws away, and i'm throwing away the biodiesel." I died for a bit there. Lol

[@geoffcunningham6823]

The gelled biodiesel was most likely due to water in the methanol. To get decent yields with this, you need very dry methanol and oil. Separation is also quite fast without water contaminating the transesterification.

[@magnuswootton7368]

use copper sulphate instead of lye, use metho and boiled linseed oil, add oxalic acid and walla air drying flexable ceramic glue.

I've been watching these videos on a binge for at least a month now and this is the first one that makes me actually want to buy all the lab equipment and try

[@K0ester]

4 year later did you ever do it? Buy some glassware and start building an amateur lab?

[@-__-_-_--__--_-__-_____--_-___]

@@K0ester no

[@VoidHalo]

Unless you have a bachelor's degree, I would advise against it. You need a lot more than just glassware and chemicals to do chemistry safely and properly. Also, almost all chemistry produces nasty fumes, and doing it outside is a craps shoot depending on which way the wind is going. Then you risk exposing neighbours with open windows if you're in a city. In other words, you need a proper fume hood that's vented to a roof (ideally) at the very least, along with PPE like a flame/chemical resistant labcat, goggles, gloves, and more.

[@VoidHalo]

I know I rambled enough as it is, but just as an example of what could go wrong. I decided one day to just dissolve some limestone in hydrochloric acid to see what I could get out of it. What I got was hydrogen sulfide because there was some sort of sulfate in the rock that I wasn't expecting. Hydrogen sulfide is more deadly than cyanide. While it has a strong smell of farts you can become "smell blind" to it at high concentrations and not even realize you're breathing this deadly gas. My whole house smelled like farts for a week. But it could have killed me if I used more than a few tiny rocks.

[@nasdfghidgf8081]

3:23 they could be glycerin. I made soap and decided to get the glycerin out, to do this I added a NaCl solution and left it over night in a shed. I came back the next morning and there were a solid soap layer and a solution layer with base, NaCl and glycerin. The blobs were in the layer with the glycerin. Keep up the good work

[@Hobypyrocom]

next please nitrate the glycerol :)

[@NileRed]

+IamIUareU I honestly want to but the legality is a little sketchy. I know I have a mercury fulminate video, but still. Maybe I just won't include the actual quantities to keep people safe. Then again, the recipe is very easy to find.

[@Hobypyrocom]

Nile Red i understand :) i had website and youtube channel for how to make the essential chemicals that you need to produce all kind of explosives, but yet in the end i was explaining too much how to find and how to make them, i noticed that my visitors were mostly young kids so i felt the responsibility to shut down the website and to delete all the videos... i was just 11 years old when i started making high explosives and energetic materials but it was different time and different way of parenting back then... you should do all sorts of explosives only for educational purposes just dont put details of how it is made... show the process without any info...

[@NileRed]

That is very unfortunate. I also started very young working with explosives and chemicals and it was a good experience. But it was dangerous. Explosives do scare me though, honestly :p.

[@Hobypyrocom]

Nile Red making explosives and blowing small stuff up is addiction (at least it was for me), i started with 0.1g and ended up at 2.5kg in few years :) that last biggest one scared me allot and thats when i stopped making huge amounts and started more scientific research with high energetic materials... i feel really bad that we didnt have cameras back then :( i had to remade the videos for my website but never ever dared to make more than 10g at a time ever again :) i was mostly making AP and MEKP and tons of black powder...

[@NileRed]

I never made quantities that large, but I do wish there were video cameras. Would love to re-watch some of the stuff I did.

[@MatthewLeonard100]

That's a really good chemistry video. Even though we can't see any spectra, the video with commentary tells the story correctly and I have no trouble believing that you have pure glycerol at the end. It's viscosity is low because you just took it off the heat.

Haha yeah. Definitely not the most efficient process. Much cheaper and easier to buy. I got 500ml for 9$ at the local pharmacy. High quality and low water content.

[@hili467]

Nile Red yeah decided to try to do the math for it, and I think even if you bought a gallon of vegetable oil at $6.30 (estimated tax included) you'd still only end up with a theoretical yield of like .114L --- 114 ml. And that's not including cost of the stuff you have to mix it with, and the time you put into it and all that fun stuff. Still a really cool video though. Whenever i watch his videos I feel like I know the world a little more.

[@NileRed]

I am glad to know you enjoy them :)

[@Andrew-my1cp]

@@NileRed If I may add, when using castor oil, highest yields were obtained by using 1.5% catalyst by weight, reacted for 60 minutes, and had a stir rate of 1000 rpm. I think your synthesis mainly lacked time. Time was found to be the biggest factor in maximizing yield. The second part you probably lacked was good stirring. I didn't do the math but I think you also used a non ideal amount of catalyst.

who could not have an interest in bio diesel in this day and age?

[@Bloated_Tony_Danza]

debbie green When placed side by side with petrodiesel, biodiesel can not even compete. It's way more expensive and at the same time, a much worse fuel. Less energy, harder to burn, more susceptible to water absorption. You literally get less, for more. Call me when you find a way to make one billion gallons of it, until then it's a joke.

[@Stacy_Smith]

Ilir Kumi I just spent $6000 on a 7.3 rebuild, due to fuel tank delamination from my truck sitting for 2 years! In addition to that I spent $1200 on tanks and $800 on installation. THAT'S A TOTAL OF $8000! Biodiesel is BAD for older systems because it's high solvent properties disolve solids that can accumulate at the injectors. ...but for a NEW truck or NEW system like I have B20 is perfect *(temperature permitting) for preventing contaminants to build up in the first place! Also ULSD has shitty lubricity and biodiesel has EXCELLENT LUBRICITY! So I would gladly pay an extra 20-50 cents per gallon to PROTECT MY INVESTMENT so it will last another 20yrs. *3:20 More advanced refining techniques have been developed to remove the components of the biodiesel that gells at higher temperatures making it a more reliable fuel. I have 2 tanks on my truck that aren't manifolded so in the winter, I will run B20 in one tank and #2 in the other. On mild days I'll be using the B20, on colder days I will be using #2.

I remember performing the saponification of olive oil at school using a concentrated sodium hydroxide solution. The glycerol would separe from the mixture as well if you left the solution without stirring. Also, wouldn't an acid catalysed transesterification be better since you'd avoid generating the saponification product?

[@eclectichoosier5474]

Without the saponification, wouldn't it become an equilibrium reaction?

Fun Fact: The a lot of those impurities in the glycerol are called phytosterols, which are closely related to cholesterol. Phytosterols are estrogenic in nature and can effect testosterone levels in men. Which isn't surprising because sterols sound a lot like steroids, and are the feedstock for synthetic Testosterone, Cortisone, and a whole bunch of other hormones.

It's interesting watching the older videos. Visually, I think they look just as good as the new videos. But the narration hasn't been "dialed in" yet. He's very much to the point and states things matter of factly with a slightly dry monotone. Not like the more ebulliant, and enthusiastic tone he uses for narrations now. And he goes into little tangents that add a nice flare and bit of variety to the videos in newer ones. Even getting a little silly. It feels much more "human" than this type of narration. Not that there's anything wrong with this narration style. It gets the point across well, it's factual, it explains everything we came here for.

Very nice and interesting. Nile Red: A quick remark I learned in my first chemistry lab back in UG - don't ever throw a magnetic bar into a flask (as in 1:50). It has the potential to break the glass (especially when the flask is staying on a magnetic stirrer) and/or spill chemicals. Always insert it slowly and carefully while maintaining the flask in an angle. Keep up the good work!
