Have you made a diethyl ether/dry ice bath? Supposedly it gets down to -100 C, which is colder than dry ice alone, so I'm skeptical.

Where did the CO ligand come from? I didnt see any you put anything with CO in the flask

When using a gas bubler or scrubber you can use a small check valve in the line to prevent the scrubbing solution from wicking back into the flask. The ones for aquariums work great for reasonable gas generation .

Please leave out the music for future videos. The tutorial information is valuable but the music makes it difficult to hear what he's saying.

What a disgusting Schlenk setup. Black tubing and filthy bubbler. Oh and no lab coat.

In chemistry there is no waste. If you can't reuse it or purify, your chemistry is useless. Remember the First Law of Thermodynamics or the First Law of Matter: nothing can be destroyed, but combined into another form. This is how our universe was created and intended to work. Cheers.

You don't grease a connection over the entire length, because otherwise grease usually gets into the piston and contaminates the product. Only grease the top 2/3 of the connection. Also, it's not a very smart idea to use a neurotoxic solvent like n-hexane without a fume hood.

He could have prepared much more with the same effort, if he wanted. It’s a demonstration, not a full-scale synthesis.

A lot of effort for milligrams of product. Wondered why one would go to such effort so I checked - en.wikipedia.org/wiki/Borane_tert-butylamine to see why.

Say that to yourself in the right context and it’s definitely funny 😁 17:42 “We are going to use the small handheld dewar on the floor.” Make sure that if you’re going to dewar on the floor that we first talk about Personal Protective Equipment for the Laboratory

Thanks for the video! Is there a way to make the color change last longer while hot other than heat? Can I add something to the thermochromic materials to make this happen?

Why do you feel its necessary to play that irritating music in the background???

@bound2ball395 2 жыл бұрын

1. can you explain why you mixed Cu(NO3)2 with absolute EtOH? 2. why you used specificly 1.2g of Cu(NO3)2 and 1.6g of deen and does it need to be in that specific number/ratio 3. are the amount of deen and Cu(NO3)2 affects the outcomes (temperature where changes occur or the result of the product). Hope you'll answer these, i would really appreciate it

How you connect the column of Drierite, meaning inlet inert gas-bubbler-manifold? How is the order of place them, please?

@wsuchemistry4107 2 жыл бұрын

The column of drierite has two connectors on it, one for in and one for out. You simply connect rubber tubing to it and then use hose clamps to secure the tubing. The inert gas comes from the inert gas source (tank, dewar, etc.). You then should have an inlet bubbler so that you know what flow is coming from your inert gas source. Then will come the drying column (drierite in this case). You need to make sure that the drierite is placed higher (vertically) in the hood than your inlet bubbler, otherwise you will have mineral oil collect in your drying column if you have too high of an inert gas flow. You can have the inlet bubbler and the drying column in the reverse order, but I feel it is a safer setup to know what pressure you have going into your drying column. The described setup also prevents mineral oil from the inlet bubbler getting into the manifold. Then comes the manifold, followed by the exit bubbler.
