Simple and Fractional Distillation

[@mystwalker479]

I'm currently self studying, i couldn't learn by just reading and listening to stuff so i really appreciate you put demonstrations in :) It's a rare thing on youtube

[@MrTylerStricker]

This was a really great introduction to distillations! I've seen several different chemists explain "distillations 101" & this was the only time where care was taken to show the finer points of setting up the apparatus, the types of glassware to be used (and their functions) & the differences between the two types of distillation.

Thank you so much! This video was extremely helpful for my exams

[@user-dp8gj2sq3m]

thanks bro helped a whole lot

[@santosjaimes1]

Muchas Gracias. Muy claro y tiene un trato agradable a nosotros sus alumnos.

Great content and the hottest chem I've ever seen.

The graph of your ideal destillation, temp vs. volume at 9:14 might be wrong. The way you are drawing it, you are getting destillate before 56°C. It becomes more obvious if you swap the x and y axis.

[@giorgiocanal1659]

It's wrong, but not axis swap. The graph has to stay between the two boiling temperature and not between zero and the highest one.

[@pelesrelewot]

I think the ideal graph should actualy start from 56 deg. Or go from origin straight up to 56 deg and then as depicted, so there should be two sharp steps

[@derikfrantz3141]

Yes, it is wrong. The lines should begin at the 56 ˚C mark as they move to the right, not at the bottom of the graph as I drew it. That's an embarrassing mistake, and I'm happy that you noticed it.

Thanks you explained very well

[@bifengxiao9300]

Thank you so much for the videos!

[@isabellabendorf9127]

very helpful also you sound like john mulaney

[@burgerasf2900]

I wish he's my lab professor

[@techiester8311]

Great video

[@derikfrantz3141]

Thanks! I'm glad you enjoyed it

[@samarsau8328]

Sir. ..this vedio is very well and I have a one request how purification triethylamine ,DCM solvent individually for synthetic purpose. ..

[@derikfrantz3141]

Thank you. To purify those compounds, I encourage you to find literature on the topic and seek hands-on help from an expert. It can be very dangerous if you do it incorrectly.

i am confused. you used a mixture of acetone and cyclohexane. In the end, the bulb was empty. So did you get the same mix-out that you put in? Because half of it should have been left in the bulb - the cyclohexane part.

Hello. I’m needing to find a cost effective vacuum controller or regulator to reclaim ethanol thru a 5L rotovap. What do you recommend???

[@jamesmurphy8676]

Why is there temperature recordings every 2 degrees increments when a distillation procedure is separating 2 compounds in a mixture with 2 boiling points? You'd expect one temperature on the thermometer to be reached and maintained while it boils and condenses over and then the second compound in the mixture. Why recordings take place every 2 degrees increase?

[@girjabaghel7899]

Nice explain sir

[@alihafezpour6383]

now, I got it : )

[@puripie979]

Thanks for👆 🙏

[@derikfrantz3141]

You're welcome!

[@zakianoomen8961]

Hello Dr. Derik, i just want to ask you about concentrating a 41% nitric acid solution by adding mangnesium nitrate (dehydrating agent) using a simple distillation : first we maintain temperature at 100°C (temp of water ebullition), collecting the half fraction which contains mainly water and raise temperature and collect a concentrated solution. Can we do that? Thanks in advance.

[@TimeSurfer206]

I can't properly answer that, but I will say this: If you want to maintain a steady 100° C, use a double-boiler. If you don't know how, ask any cook.

Thank you handsome
