UC235 - 2012-12-09
A Sodium-Lead alloy containing about 10% sodium (1:1 mole ratio) is prepared by simple melting of the elements together without need for specialized equipment or inert atmosphere. The resulting intermetallic is very brittle and readily powdered to give a high surface area, highly effective drying agent for ethers and hydrocarbons for which more complex drying methods utilizing metallic sodium are normally used. The NaPb reacts more slowly with air and proton sources than pure sodium (simplifying handling and storage) and the residues can be quenched without risk of fire. The intro music clip is from "Stealing Fat" by The Dust Brothers. I believe this falls under fair use.
Whered you ever go UC? You havent posted a video in forever.
@HUsoldier171 Maybe he made a batch of (CH3CO)2O and got told on by someone, perhaps it is illegal were he is.
lol just a theory.
3:19 sodium fish !
References suggest that at about 225C, the exothermic reaction forming the alloy sets in and the mixture gets very hot. Interestingly, this is above the mp. of sodium and below the mp. of lead. I'm not sure what the mp of the the product is. The molten alloy will burn if exposed to air forming horrifyingly yellow material that is probably sodium oxide and peroxide floating on molten lead. Some lead oxides may be formed as well.
This is one of the best channels on chemistry. I was pleasantly surprised to see you're actually taking time to draw and explain the reactions on a piece of paper. It's really great thing to do. Most of the videos that deal with organic synthesis are not much better than a fancy show of nice glassware. You're really doing this professionally, old school, so you've got yourself a new subscriber. :)
Great video. I will be using this from now on to dry my solvents. Thanks!
Thank you, UC235. I watch and re-watch all of your videos in order to learn as much as possible from one of the finest chemists on YouTube. I love the way you describe your procedures in such a clear, concise, down-to-earth, professional, and superbly interesting manner. Even in the relatively rare cases when things do not go quite as planned, I learn a whole lot from these circumstances. Again, I kindly thank you and wish to continue to learn more from all of your chemistry adventures.
Where have u gone dude, keep the videos coming, your a great inspiration . good work
I wonder if he made Tetraethyllead with this and then died, U235! tell us you are not dead!
Matt Hunter He Made a Comment With this Account before around 6 Months under a Video of dougslab... so probably he isnt dead..
and He is still Active in the Sciencemadness forum... there he Posted something 4 Days ago
LoLetsPlay i think this is NileReds old Channel. It lines up where he stopped making videos on this channel and when Nile red started uploading on Theo there channel
You should put text in your videos. It is easier to read than to listen. It makes it easier to take notes (on other videos that are more complex).
7:10 Also, it looks like silicon, not bismuth.
Looks like bismuth to me.
Wow. Bullets made from that alloy would mess a person up.
Why no more videos?
Is it also possible to use metals like tin instead of lead for the alloy?
i want a HD video
So... Is this the end of your channel? More importantly: Are you still alive? (not like the one that made chemical weapons from WWII and got sarin poisoning)
@***** Correct, sorry.
(Mi a csöcs, te mindenhova követsz? Kezdek félni. o_o)
A következő videóban megemlítelek, ne félj te attól :D
Did someone actually make sarin and die?
115k views means you should have received at least ~$100 in ad revenue. Perhaps use this towards some better microphone technologies. Your videos are really let down by the audio.
clever & smart. did you considerusing a microphone you could attach onto to your labcoat? it'd be a great add to your series cheers!!
RIP
Not just because of organolead compounds, but the sodium will explode with halogenated carbonhydrogens ;)
*hydrocarbons
What are products after reacting with water?
another nice one, thanks.
Qué chévere
This should dry methanol for biodiesel production, right?
methanol reacts violently with sodium
Sodium hydroxide and metallic lead. In fact, after squirting that water into it at the end, the remnants in the mortar were soft enough to be squished together with the pestle.
we are still waiting xD we belive!!!!<3
I just thought of something concerning Na wire...I wonder if it could be made by extruding the Na through a pasta machine? The Na might not be soft enough, though. One solution might be to alloy it with another metal. Unless you accidentally made a eutectic alloy, it would not have a sharp melting point.You could then heat it so it would just soften a little. You could immerse the whole machine in hot motor oil. That would both maintain the correct temperature, and protect the Na from moisture.
now if you did it with potassium would that work? would the end result be stable? would you use less potassium since its denser the sodium?
You can get rid of the noise if you run the audio through Audacity Beta or a similar program. Audacity is free. Sample the noise and remove it in the Effects menu. A tip to aligning audio and video: Film a snap. Hope it helps. High Five.
I don't put ads on my videos, because I find them annoying. I also don't have my home page video set to autoplay to boost my view count. I will try to figure out a microphone solution...I am using a sealed-case waterproof point-and-shoot to record these though. I don't have another camera. I was also getting sick at the time this was recorded so that didn't help.
I do not think this should be used for chlorinated solvents, as it will form organolead compounds.
To dry diethyl ether using this would you simply distill the ether over the alloy? How much alloy should be used with respect to the solvent you are drying?
the sound of this vid is horrible other than that awesome vid

3:15 Sodium - the snack that smiles back?
