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.
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
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’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?
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
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
@@wellcomecentreforanti-infe6171 you are vacating the air from the flask with hydrogen, making it a hydrogen rich enviroment, never seen someone do it with a syringe before, my comment was pretty rudimental
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.

Thanks fpr the detailed explanations :)

Is the “product” a substituted amphetamine? 😐😐😐
Or phenethylamine? That alpha methyl doesn't make all the fun 😅

Hi there. not sure what you mean by "the space be flooded"? Let me know how we can help you with that bit.
