Thanks fpr the detailed explanations :)

thanks

I’m watching you adding ethanol and the predissolved reactant and I have already two questions: how can be the ethanol dry and the reactant moisture/water or oxygen free if you’re adding it this way?

NEVER use septa for hydrogenations. They will leak when pierced. That leak could blow atmospheric gases over your catalyst in a flammable solvent when you do the last purge. Then your flask can spontaneously disassemble with a ear drum destroying conclusive blast. You will kill your lab partner and wished you paid attention to this comment because now I'll tell you to ALWAYS use a 3 way vacuum adapter with the standard tapered glass joints. P.S. I've never been in a chemistry class. Not in highschool and definitely not in college. Even I know these things. That means there is no excuse for ignorance that leads to catastrophic events.

Which oil is used?

Very nice video, two comments; once punctured, septa are not terribly vacuum-tight, meaning under vacuum, atmospheric air could be sucked in through the puncture. If the volume of hydrogen is completely consumed by the reaction, the setup could generate a partial vacuum, which once again could lead to atmosphere ingress.

Great video!

Thanks WCAIR; I appreciate this video!

Hey, I was just wondering if you have to evacuate the air out of the flask and back-fill it with nitrogen if I were using a nickel catalyst? Does it effect the hydrogenation reaction or is it evacuated just because it reacts with the palladium? I'm doing a school lab investigation on finding the activation energy of hydrogenation, so I was just wondering if that step would be necessary for my experiment. Thanks!!

I have a question, how much would a setup/lab cost if you would like to do hydrogenation "industrially"? It's because I have an idea for a product I'd like to create, synthesize like this and I wondered how much this would cost on average & the amount of substance one could "hydrogenate" at a time? Thanks

Thanks

Great explanation

I like how you injected the hydrogen with the balloons and the syringe but shouldn't the space be flooded, I assume you just have to wait a lil longer for the correct amount of gas or equalization, just never seen it done like that, it was a good idea

Excellent work that deserves admiration ..... I love the miniature industrial processes that take place in the laboratory ..... Excellent work .. Excellent work ... Thank you very much

Thankyu

Video doesn’t play

If the ether is not sodium dried, the reaction yield will be very low.

Clear explanation hats off to your efforts dir

O' HOW I DISLIKE LOONIE MURDERING AMERIKINS

Fantastic effort at demystifying AI/ML.. As usual, appreciate your ways of using simple tools and language to make the point...

Very much enjoyed the story narration. Great to see you on the video screen again.

Superb kaushik sir😊very impressive work.Story and story telling is very professionally done. I enjoyed every moment of it👏🏻👏🏻👏🏻

Love the ending😅

I never got why Physics is considered a science. It feels more like a math.

Nice, 👍 all the way from Texas to here, are you used to our climate yet? lol wet and cold!!!

Really interesting. Thank you for sharing your story. CH.
