A Simple Distillation Explained

Professor Davis builds and runs a simple distillation apparatus to separate ethanol from water.

Thanks for pointing out all the small but important details.

Enjoying those great courses series videos. You are the man Professor RDjr. Love your clear thorough way of teaching. With a touch of humor, that shows just how cool you are. Most individuals as accomplished and with credentials as yourself have an extreme case of God complex. Thanks for everything sir. It is greatly appreciated.

When laboratory is also online because of covid

when inserting the thermometer into the thermometer adapter, you should hold the thermometer very close to the adapter when pushing it in. if you hold the thermometer far away from the adapter, there's a chance that you might break it. other than that, great video.

I sure would hate to see the complicated version of that, but im green, so, thanks for the demo.

Dear Professor Davis thanks a bunch for the insightfully meticulous video. I have a question: in some situations the water condenser inlet and outlet of water are exactly the way you have displayed in your video. However, in some situations the entrance and exit connections are mentioned to be exactly the opposite. Which process is correct in which situation? Please guide me. Thanks.

What about using a Vigreux column to avoid reflux (especially when using a 250ml or larger volume Florence flask)?

For showing the general set up of distillation the video is really good. But one should not follow this technique as it is. The safety part is completely ignored. The video should start with (1) proper inspection of glasswares (2) attaching the water line to the condenser before attaching it to the line (3) attaching proper clips for the water line to the condenser. Also one should have cut resistant glove during the job.

Hi.  Excuse me, I had a question: I want to produce 70% alcohol for disinfection by combining sugar and baking yeast and distilled water. What should be the temperature of the fermentation liquid in the barrel during the fermentation stage?  What should be the ambient temperature?  I am a member of your channel and I watch your clips.  Thank you very much and good luck.🙏❤💜💙🌹🌹🙏

The condenser is a very cool piece of glassware. I wish I did my degree in chemistry :/

Can I make lemon essential oil with this method? Is there a difference in yield using two flasks? Will I need to add anything other than distilled water and lemon peels? Thanks?

[markarca]

The ethyl alcohol will boil first (70 to 75 deg C) and water will boil next (100 deg C).

[coreyjamesjernigan]

Great explanation on how to set up and run the simple distillation but I don't understand what you are aiming for cuz you were still getting ethanol towards the end into the H2O??

[WillTunna]

Could you use a flat bottom flask directly on a hot plate stirrer instead of the round bottom in the mantle?

[abiyyurahmat]

why would the water supply should be connected to the lower port in the condenser?

[littlehills]

i place a thermometer at the vapor front to the condenser elbow but the reading im getting is 85c for ethanol. do i raise the thermometer tip higher then the elbow ?

[priyabaila]

very good video and well explained as well

What should be done to prevent material loss while Simple Distillation ?

[lxkzkmh]

Can I get a drawing/plan or any info about the system built onto the wall for clamping the equipment, please ?

You should add a Fractional column between the three way adapter and the RB flask. This is a simple distillation, I understand, but ethanol need a Fractional column.
