The voices in my head told me to make sodium amide

- Опубликовано: 27 сен 2023
- Today we make sodium amide by first reacting urea and sodium hydroxide to create ammonia gas. We then dry the ammonia gas, condense it, and slam-dunk some sodium metal in it. We also need a catalyst for which ferric chloride was used. Congrats we have now made sodium amide! SUB or else.

How did you bare to stay in the garage while so much ammonia is boiling off without a fumehood - did you wear a full face gas mask?
I guess it would be better to keep on cooling the liquid ammonia while reacting with sodium.
And if you synthesize ammonia with only a little or no heating by dripping water onto a mixture of sodium hydroxide and ammonium salt, you get a much more uniform gas stream that is already cooler and contains less water vapor. The best way to dry ammonia is to use a mixture of solid sodium hydroxide and calcium oxide in a gas washing bottle. The perfect device for trapping liquified ammonia is a so-called cold finger.
Ferric chloride hexahydrate isn't suited as a catalyst for that reaction, unwanted interactions or decompostion reactions are to be expected caused by crystal water present at the same time. So it should be anhydrous, which yours obviously isn't. By the way, one hazard warning on the bag is incorrect: ferric chloride never causes or supports fire.
The anhydrous ferric chloride must also be added first and then the sodium. This prevents the formation of solvated electrons, but increases the yield of amide, which in the other order is less than one percent.
Once electrons have been released without a catalyst, sodium is formed again when the ammonia evaporates, which oxidizes to sodium oxide in the air. This also explains the weak reaction of the product with water.
Sodium amide is very sensitive to air and humidity, its oxidation products are explosive and friction sensitive. Therefore sodium amide must be stored in sealed ampoules filled with inert gas - or under mineral oil if a resealable bottle is used.
If any traces of oxidation are visible the stored substance has to be disposed off immediately with greatest care and caution.
Thank you for all the info brother. I really appreciate it! I wanted to showcase the solvated electrons for the video, but putting in the catalyst first seems far superior. Someone online said you could use ferric chloride (which I had on hand). I didn't even think about it being in the hydrate form! Maybe I will go put it under some mineral oil. Thank you for watching!
High-Vac the ferric chloride. My gut says 60c, but idk that much about salts
@@ShadowDrake102
No, in the laboratory anhydrous FeCl3 is made from the elements.
Vacuum evaporation is used to prepare the hydrate in its solid form, it's not suited to remove the water from the crystal lattice.
@@experimental_chemistry awesome, thank you!!!
Electrons decompose into Neutrinos if there's "no where" for them to go?
There's an old saying: "You're not a chemist, unless you've nearly gassed yourself at least once." - that Acetone event counts, consider it an informal graduation. For me, it was Chlorine :P
Chlorine is crazy😂
Oh mine was chlorine too! A really small amount, but enough to smell despite it being in the hood. Embarrassing to explain to my labmate/boss that we should go stand outside for a little while. (the lesson learned was not to uncritically follow procedures from old chemistry books of unknown provenance)
I was dissolving some minerals using dilute muriatic acid and decided to add some sodium metabisulfite- the reaction wasn't violent but the smoke was noxious and definitely contained plenty of sulfur and chlorine. i wonder what metals were in the rock acting as catalysts, but the crystals i dissolved out were quite pretty. lol.
First gassing event for me was a mixture of chlorine and bromine when I tried to make bromine at 14
Chlorine too, from my chlorate electrolysis cell. I needed to adjust the pH down and added the HCl too fast. :)
What I like to do when I want to look inside a frosted over flask in the lab is to wash down the outside of the flask with acetone. This keeps the frost away for a good amount of time without the scraping :)
Came here to say that.
Ethanol also works quite well. It also doesn't evaporate that quickly, I think.
"Watch this funny meme"
Dude I had to watch that three times
The "delusional safety feature" line made me laugh. That and "...alcoholics.." especially. Thanks for being fun. A good channelbto see on here that explored reactions of sodamide is "Chemical Force".
I feel like I’m gonna end up on a list just for being subbed to you lol
Chemistry isn't illegal
@@K0ester I guess you’re right, this guy is the RUclips king of List 1 precursors and he’s still uploading videos
@@TagetesAlkesta im also a amateur chemist. Ive got alot of "listed" chemicals and have bought many others. As long as you're dealing in small amounts, and not using them to manufacture illicit narcotics, you'll be fine. At least ive been so far
@@TagetesAlkesta He probably has the proper documents, or he lives somewhere besides the US
I hope you thoroughly enjoyed this, the Birch reduction was by far my least favorite synthesis in undergrad ochem lab...
Lab tip: Sprinkle some methanol, ethanol or acetone on the test tube and you won't get the frost for a while.
The proper condenser would be a reflux one. Especially when scaling up reactions to >5L, the #24 or even #29 condensers become useless and one needs a good wide condenser you know from rotavaps and chemical reactors.
The only reason I used that one was simply cause I bought it and just wanted to use it 😂. I know it wasn’t the best
@@chemdelic Yeah - overfilling a condenser happened to me several times :)
Was just about to comment this
I’ve seen solvated electrons before and I think that’s one of my favourite reactions
I like how your videos are directly to the point, and not optimizing every step down to the last microgram. I got a somewhat into hobby chemistry during covid lockdown times and this is also how I like to do chemistry: not calculating everything exactly but watching, thinking and making deductions on what happend.
(NOT meaning just put random chemicals together, just referring to exact concentrations, ratios and so on)
You definitely didn't fail in making me laugh; something about the false sense of security and absolutely fully understanding it intrinsically and even having DONE something like it, although not with chemistry (not like you said about that yellow tape just before ~5 minutes in
As a Year 13 ( A level student) watching these videos restores my faith in chemistry ( Organic is best :P )
The videos are getting better and better mate fucking awesome brh
These video titles just keep getting better and better ❤ 😂
Maybe the voices should tell you to make lithium salts
Voices have some really good ideas despite the fact they might not be real.
"And a Graham Condenser because I havent used it before"
Sums up my experiences with Mr G. Condenser.
omg, that was a thrilling one!
Awsome brother👍
I enjoy your videos. I am a glass blower, and I could make you some vacuum jacketed test tubes that would be better for filming cold substances.
That would be cool! Though I would need to set up a PO Box!
Sick intro brother!
“I had to air my garage out cuz sm acetone was in the air” boiiiiiii if I would have been in your place the headache I would have gotten would be through the roof
I like the new intro!
Best video titles.
Very nice!
Thank you brother
Awesome thanks for creating this.
Side note, I wonder if mineral oil on the test tube exterior would keep it from fogging over.
As in giving the test tube a wipe with a mineral oil soaked rag after removing it from the acetone bath? I'm not sure why, but it's hard to simulate that in my head. The first thing I think is, "well you would still have mineral oil at around -50C exposed to ambient moisture, and that would still condense moisture and freeze." Then I think, "but it wouldn't stick, right? it would slide off. And the frost presumably wouldn't pull the coating of mineral oil off also since they don't mix?" (it's always fun to try to reason out the answer to see where ones assumptions are incorrect) My GUESS is the sliding frost would still get in the way of filming the result also I THNK the frost wouldn't be heavy enough to fully drop off the tube. It was fun to think about regardless.
Ma man really be out here putting the milk in the bowl before the cereal.
I still can't believe I once made anhydrous ammonia in my parents' garage, with no respirator, by just boiling it off some 30% ammonia solution and using a condenser packed with calcium oxide. I collected it in a receiving flask in a plastic cooler filled with dry ice and ethanol, and then put it in a Chemglass glass pressure flask rated for less than its vapor pressure at room temperature, storing it in my parents' basement for weeks while it thankfully never exploded. I finally got around to doing a Birch reduction on benzene that I also handled with no respirator. Very stupid, but at least the solvated electrons were pretty!
I later learned that there's a much safer way of doing a dissolving-metal reduction that still involves beautiful solvated electrons. It's the Benkeser reduction, same as the Birch except using ethylenediamine instead. Preferably with some added propylamine or butylamine to reduce the aggressiveness of the reduction so you don't mostly end up with cyclohexane instead of cyclohexadiene. Ethylenediamine and propyl/butylamine are still corrosive and still smell horrible, but raising the boiling point above room temperature does reduce the danger quite a bit.
In hvac isoprop alcohol is used to prevent sight glass frosting
Going to get some of that wine preserver
Bruvva, I've been on that list for ages
Had the same issue the first time I used a graham condenser. It didn’t want to drain back until I separated it from the reaction flask
Another precudure to prepare reliably pure sodium amide is to let oil- and oxide-free sodium react in a stream of dry ammonia at 300 degrees celsius. It's then absolutely necessary to ensure that no air can enter the apparatus.
I made sure to download a copy for when the cops search my computer 👍
I got a question: if all the residual sodium metal and sodium amide was removed from solution, but the solvated electrons were still in the Liquid ammonia; what would happen to the electrons? Or is there Na+ in solution still which is able to reuptake the electron?
I like the new intro
Phenomenal phenomena are my favorite kind of phenomenon
Mist the test tube with a small spray of diluted dish soap. Used to have the same problem with diesel tank level indicators every winter.
Maybe the tape did something after all.
I wonder if an application of Rain-X over the outside of the test tube would prevent frosting long enough to get a good shot of the contents?
A Graham condenser is completely unsuitable for such actions. A Dimroth or intensive condenser is used for this purpose.
Bit of oil on the glass to prevent frost?
2:43 Dude. Always add the cereal before the milk. 😂
Is that the intro to the law giant ads in alburqureque?
Acetone is your friend. Next time, use some in an irrigation bottle to clear off the ice.
Niceness
Dude I'm looking at the back of a marshmallow container and it says they've got tetrasodium pyrophosphate in them can you make some of that??
Perhaps some ammonia will unacetone my garage!
Lol.i thought the mistake was every bit as good as video.
I wish you would tell more info about the chemicals you're making like what they're used in what they've been used in the past the history
For some reason I have the feeling that adding that information would tip the channel into the "ban" category.
If you steam under the test tube real quick it will create a glass like surface fer lookin' purposes.
It will boil off a bit of NH3 tho so, take care
Will dry ether catylize this reaction?
Do you know how to make CBR aka 2-gb
Why did you go with acetone over ethanol for the dry ice bath? Just whatever was on hand?
Acetone is way cheaper for me!!
I used to work with the dea at my last drug manufacturing plant, i dont think they care as long as you sign the right papers and dont harm anyone
Wrt frosting of the tube: just keep squirting it with iPr-OH, or immerse it in another glass vessel full of iPr-OH (ideally the outer vessel has a flat face to view through). I do this for checking frozen biological samples with a microscope
3:10 just watching that made me sweat, thinking about ignition sources.
You should wet the test tube with alcohol to prevent frosting
Great
bro i was looking for that...
Call me Isoprene, cus when I heard these jokes i was fucking diene
Based
That intro was what would happen to you if you tried to recreate what this man does without PPE!
I had a respirator!! Still smelled tho
Now turn it into sodium azide
High school organic chemistry makes you forget how strong NaNH2 is for a base as it comes up a lot
Cool
Do it bro.
Oh lord! I hope you didn't have any plastic equipment close by when that acetone volcano went off!😢
Lucked out!!
Coat the test tube in anti-stick liquid so water doesnt sublimate on it
A little PFAS cant hurt if you make liquid ammonia
I would like you to make sodium azide with sodium amide 😊
10:00
I gues you could say the moist air ArGon-e
I finally figured out why Nile red doesn't make videos that often, it's because he's simply every other chemistry RUclipsr in existence since his inception. He should really copyright his cadence......lol
You're so funny. "Don't do this at home!" Like people would have benzene, liquid ammonia and sodium metal just laying around their place? :)
new chemistry just dropped: schizochem
😂😂
What would happen if instead of using sodium metal you use lithium metal and mixed it in about 25 grams of Sudafed asking for a friend
sodium metal can be used just fine, lithium is just another option that's easier to get otc. Only thing to keep in mind is that when using sodium as the electron source you will have to use more by weight than lithium.
@@calebeck7586 really I didn't know that but I thought it was maybe possible when I seen the sodium turn the ammonia blue in the same way to lithium does
@@jamesproffitt9641 yeah reaction with sodium metal in liquid ammonia solvent is the traditional birch reaction, whereas lithium would actually be a benkeser. Cool thing with benkeser reactions is the option to use solvents other than liquid NH2 like ethylenediamine to solvate the electrons.
Did you have a preference for Urea instead of ammonia nitrate?
I just had this on hand!
First hell yeah
Who else came here because of the video title?
DEAmides your business
I'd probably listen to my voices more , except I would need an interpreter, since most of them do not seem to speak English .
And there is always at least one of the little fu&$#@$ snoring .
goofy intro
Agreed
less nile autismo explanation cadence and more memes
Can you use other sodium compounds in liquid ammonia to make NaNH2?
