Great video . Not useful in parts of the world where NaNO3 is a controlled substance but that doesn't affect the quality of the video. Nice job . I'm going to check your other videos, I'm sure it will be worth it . Cheers
Not bad, but making TLC of benzene, this is on the edge of madness XD Definitely, for a bigger scale reaction, add ice made from distilled water into the flask (heat buffer for any temperature spikes), I would add aniline first and then add acid into the solution (so it won't form salt on the pipette or flask walls). For extraction, if phases separate, then separate them first before the addition of organic solvent. Just good practice, less solvent is used most of the time. Also, why not just distill off azeotrope with water? And then have pure benzene?
Can confirm - I descended into madness. And good advice! Agreed I think those would improve things. And isopropyl alcohol also forms an azeotrope with water - so I'd still have to find someway to separate it out.
@@nomcopterlabs True, but you can easly salt it out together with benzene, and separate both XD I think that you will have better end state than with extraction. And with just salting you could pprobably say more about yield just by comparing volumes of organic layer in test tubes.
Really enjoyable! When doing the TLC, I realize you said benzene evaporates quickly but does it evaporate off the glass rod between the time you dip into the benzene standard and spot and then dip that same glass rod into the test samples and spotting? Is there residual benzene standard on the rod being mixed into the test sample I guess is what I’m wondering.
I spotted the capillary tube on a paper towel in between sampling which should completely empty it. The cohesion of the liquid is stronger than the adhesion of it to the walls and so it _should_ be pure enough for this test.
Can you make a video covering the birkeland eyed reactor? I know it's been done before, but it's ineffective. I bet you can make a much more efficient reactor thanks for the amazing content!
So isopropanol when used does this make acetone or just isopropyl nitrite since the diazonium salt is being reduced? I might have that backwards and its oxidized. Also what role does the sodium acetate play? Maybe a buffer or something?
This is super cool!!! 🎉
Cool lab time watching all the processes!

I'm not into organic but still a good watch.. methodic and such. Good vid.

I would expect so! Yeah the sodium acetate functions as a buffer. Most of how the reduction with alcohol works I got from doi:10.1021/ja01555a044
Dang the part with the fast addition if that was room temp it would have runaway for sure 😮
Yeah I thought the still generally low scale would be enough to keep it low in the bath - guess still too much heat generated!
@@nomcopterlabs hey you got away with it this time! 😂
Why'd you stop making content?
Been busy but have a couple more videos in the works now!
@nomcopterlabs Awesome, keep up the great work.
Nice thumbnail
Benzene can save us from suffering like the other populations. Benzene is deep strong dark and light.
low yield= dislike
78% is a lot higher than people typically get from the dry distillation of sodium benzoate. That's usually closer to 40%
