bro you just made the distillation concept click in my head, thank you so much!! the key is understanding that the vapor composition is different than the liquid composition

Hi lonewolferton, I really appreciate this comment. Teaching is my passion and I hope it comes through in the videos. Hopefully many more will be on the way this year. Keep your chin up and remember, if there is a will, there is a way to make your college aspirations come true. Enjoy the videos!

Hi Kris, I try to keep the videos short. Discussing packing with steel wool, glass beads or even those columns with actual physical plates would be a cool enhancement. I may yet explain this technique in a later release of the video or in a different video all together. As a side note, we have learned in our labs that even when students neglect to pack their fractionating columns, they still get better results than running stills without the column at all! Thanks for the comment.

Happy to help! Be sure to check out the other videos in my DISTILLATION! playlist.

So far, the best explanation I've seen on this topic. Thank you!

Finally, a clear and simple explanation of fractional distillation. Many thanks for producing and posting this video. (I wish that I could give you more than one thumbs up.)

Amazing video! Thank you professor for your wonderful upload.

Can't believe such a nice content us 7 years old .. It helped me alot.. That is what i was searching for

It took me forever to understand the material until I saw this video!!! Thank you so much, you're the best teacher ever!! God bless you <3

This is a simplification which I needed a long time to understand. If you heat up the first liquid mix, it's already changing its mixture while doing that (liquid part). So you won't get a 80% purity, it has to be less. You only get almost this purity, if the second amount (the evaporated stuff) is much less then the first.

This is absolutely awesome. I understood why we use a fractionating column now. Thanks a ton.

Thank you for the comment, hamood. That is why I do it! Please pass the channel on!

Thank you so much. My textbook and professor were both confusing, and you explained everything I needed to know in 10 minutes.

what can i say, I spent 4 weeks in uni trying to understand it, a 9 min video that you made made me understand the whole concept thank youuuuu so muuuuuch

This just saved my lab grade coming up on Thursday!

Thanks a bunch, I never had this much clarity about this topic though I read it many times, excellent explanation with apt animation, feel excited

I watched 4 videos and this was the first one that actually clicked for me. Thank you!

THX I learned so f****king much, you ezplain well and at the perfect speed.

Thank you for this video!! My prof never even brought up gas laws and trying to read the liquid-vapor condensation plot with no context was driving me crazy

can even tell you how much this helped! thank you💞

You seriously couldn't be more clear. I love this video.

The best ever video for explaining distillation. You are awesome ! The biggest plus is explaining with the T xy Graph and theoretical plates . This is what we expect from every professor. Please also include how it relates with xy graph and Mc cabe thiele method. Thanks once again :)

Hi Anxious. There is no water in the jacket around the fractionating column. Reflux condensers are often re-purposed for this task, but NO WATER is used, because a temperature gradient across the column is crucial to proper function. As condensation forms in a higher (cooler) region of the column, it begins to descend and vaporizes again in a lower (hotter) region. Often, columns are packed with inert solid material to maximize surface area on which this process can take place.

@@Phoenix_Atlas yes. In fact there are specially designed fractionating columns that do not contain the outer jacket at all. I use a Vigreux column much like this one: www.labdepotinc.com/p-64122-distilling-columns-vigreux?gclid=CjwKCAiAxJSPBhAoEiwAeO_fPx7gZ0oAMBNtm9ImDm9HRYYKEIKixVUg43_DKHTvHdP3PE2jSEOYJxoCR8AQAvD_BwE on my setup. Those columns are fine to use as well, although they cannot be re-purposed as a condenser should you find the need for one.

Thanks so much for this video! Now I understand how fractional distillation works. I have a question: in an azeotropic mixture, we can't separate them using this method. Is it because they have similar partial vapor pressure?

This is exactly what I wanted

HI Shane. There are clearly some simplifications in this video which are intended to make it easier to digest. I disagree with your assertion that no vaporization happens in the column. There is a temperature gradient along a fractionating column, so as condensed liquid descends the column it has an opportunity to re-vaporize, thus becoming more enriched in the more volatile component. To say that it is simply refluxing toluene and distilling benzene is also an oversimplification.

Thanks a bunch. A big big bunch!

Yes. Reflux condensers are often re-purposed as fractionating columns. When this is done, it is critical that NO water be used in the jacket as this will defeat the entire purpose of the column and amount to simply refluxing the mixture. This is a common mistake made by introductory students who don't read the procedure carefully before going into the lab!

this is a great illustration!! good job ! but i have a question what about the natural progression of the system won't the system raise in temperature to accommodate the loss of the vapour pressure so the liquid can still boil?? and wouldn't that reduce the purity of the vapour gradually containing more of the less volatile liquid?? and how would the plot proceed in a continuous distillation ?

@ChemSurvival

9 жыл бұрын

YES! That is exactly what will happen! You can see my explanation of it here kzread.info/dash/bejne/oHp-25h_j6ibYNI.html We usually simplify introductory explanations of distillation by only considering the first moments of the process, when the composition of the boiling liquid has not changed appreciably. However, as time passes, it will indeed become more concentrated in the LESS volatile solvent. This results in a constantly (though not necessarily consistently) changing boiling point for the remaining un-distilled liquid. Please check out the video linked above and share with your friends/classmates/students/teachers

after having seen a few of these sort of videos I don't see how is that there are dumping lands where toxic waste is stored... where the important utopic argument is that there is no way to separate the toxic stuff back into its primordial elements... to me, it seems like these sort of videos prove that there are some good ways to deal with all sorts of pollutants/toxins and other junk that may have been created as a by product of a process

Thank you for your video. nice. We can distillation of Ethanol and Methanol?

How is the reflux ratio related to the reboiler? Thanks!

Really useful

Thanks for this, and plz answer this question, why did we say the benzene will condensed or distilled? why not toluene since it's a mixture? is it because of the boiling point was only 80 not reaching 110? thanks for any help

Brilliant explanation! It's a pity it took me so long to find this. One question though (if you're still around :) ) - With two miscible liquids with significant boiling point differences (as per benzene/toluene), Is there any advantage in warming the fractionating column to the boiling temperature of the benzene (the lower of the two boiling points) to minimise condensation of the benzene in the column and perhaps give it more "encouragement" to reach the top of the column?

@firebubble5911

2 жыл бұрын

I have the same question but I think if u had a warmer column the faster it would go but it would be less pure because there would be less reflux of the toluene
