How to make Glycerine (Glycerol)

This video was requested by a commenter...I don't remember who, but this video is for you! I went with the method of producing biodiesel, but you could also go with simple saponification (different procedure though).

The process is very slow and long. It is much easier to simply buy glycerol from the store. It would be much faster and much more pure than making it yourself.

Glycerine can be made from triglycerides in vegetable oils. Most bio-fats are stored as triglycerides which are made of 3 fatty acids and a glycerol backbone. This is the same method as making biodiesel from vegetable oil. where glycerine is normally considered a by-product.

Your final yield is absolutely clear, very nice man!

[Headshotted]

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

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

This was EXTREMELY helpful and very well put together. I use glycerin as a preservative. Thank You very much for all your hard work and dedication in making this!

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.

Great videos. You have opened up a whole new mysterious world for me. Thank you.

IT WAS REALLY SATISFYING TO WATCH THE REMOVAL AND DISTILLING OF THE IMPURITIES AND THE METHANOL AT THE END....GREAT YOU FOR MAKING THIS VIDEO

[MatthewLeonard]

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.

Thank you so much, u r a life saver. I'm thankful that many channels on youtube provide experimental chemistry content. However, your channel provides more details and discusses important topics by the preparation of common needed chemicals. Your channel helped me alot in improving my practical chemistry skills.

I'll tell all of friends about ur channel. Please keep up the good work.

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

Awesome video Nile. Next, you could try to synthezise Ethylene by dehydrating Ethanol using Aluminum Catalyst Medium. And then react Ethylene with Carbon Monoxide to form Carboxylic Acid.

[costafortia]

Oh okay… that was pretty simple and straight-forward.

[RandomExperiments]

Nice synthesis, even though I would order it online. Glycerin can be used to make soluble starch, which is quite usefull for several experiments like the iodine clock and iodometry.

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 was probably my comment you read. I asked you because I was frustrated there was no glycerine production video on youtube, and if you search "how to make glycerine" you get a bunch of homemade lip balm video.
I'm sorry I missed your effort until now, but I know your other subscribers enjoyed it as much as I just did. Thank you!

fantastic video. clear and easy to understand.
still... 800ml vegetable oil ---> 24ml glycerine.... >_>

[santoshiparganiha]

This video is best for making me understand....
Well done....
Keep it up👍

[peacebrothersgv]

Thanks, i cant wait to add it to my acid collection! :)

[nahclassified]

I think we all know why we are here. You already have the nitric and sulphuric acid, dont you?
