The reaction formula you showed doesn't show any nitroethane product, just 2-butanol. UA-cam needs to bring back the dislike counter so people don't waste time watching misleading videos
The reaction is wrong: the electrolysis of alkaline carboxylate causes the Hoffman's decarboxylation and the formation of radicals reacting each other. So 2 Et-COO- -> 2Et-COO + 2e- -> 2Et* + 2CO2 + 2e- -> But + 2CO2 + 2e-.
Perhaps he wanted a reaction between the radicals Et* + NO2* -> EtNO2 however their formation is subdued a different voltage and it brings a mixture of But, EtNO2, O2N-NO2.
I don't believe there is some butanol. So has he too much confidence with chat GP or does he need more confidence with chemistry books?
Your quality and commitment is high and I'm always waiting for that next video man! Keep doing your thing your potential is flourishing so much! Awesome to see from your first chem video to now how fast you've grown and you deserve it with the dedication you've put in.
A suggestion - one can solder to graphite using a gallium-based solder.
The most interesting reactions are the ones that seemingly only few people can replicate. Here are some reactions you might want to consider since I don’t think I’ve seen them on YT before. The Gallium/Aluminium amalgam reduction of an imine supposedly works the same way as the Mercury/Aluminium amalgam. My theory as to why the reaction usually doesn’t work is because the gallium has poor kinetic propagation through the amalgam. Basically it just moves really slowly if you are using catalytic quantities. By mixing the gallium with indium and tin to make the alloy Galinstan you can lower the M.P. Of the mixture making the gallium more fluid, this allows it to spread through the aluminium faster. This sounds trivial but it’s very important! The gallium itself won’t react with the solvent (water/alcohol) and essentially acts as a surface for electron density to build up and be exchanged during the reduction. If the aluminium is not amalgamated properly it reacts with the solvent directly and generates wasted H2 gas which leaves the system. H+ ions in the solvent have a higher reduction potential compared to the iminium ion. Another reason you need sufficient gallium is that it also serves to remove the passivation layer from the aluminium. This allows more to keep reacting. Finally you could also consider doing a video about the cleavage of a styrene to an aromatic aldehyde. You can supposedly do it with cold permanganate e.g. to make benzaldehyde from cinnamic acid or piperonal from piperine but it always gets over oxidised to the carboxylic acid. Most likely it’s because people add the permanganate way too fast. If there is any lingering purple colour after each drop wise addition, the concentration is too high. You also need insanely good stirring for this reaction. By reducing the amount of permanganate used you will only generate the intermediate glycol which you can then cleave with sodium periodate. Chem player covered this method but it’s gone from yt. A working updated version with a higher yield would be awesome.
So how do you know that you got the product that you wanted rather than something else?
Also your formula shows 2-butanol instead of a nitro compound.
It is called a (Non-)Kolbe Electrolysis - and I am afraid chatgpt hit a home run - the robot's research is sound
This channel heckin rocks!
I was estonished when I learned about electrolysis that usual 1e(-) proces can lead to dupplication (dimerization reactions) thus R-CO2(-) will bring some R-R and allow for easy isolation as hydrocarbon (gaseous or liquid).
There was a side note in those books about addition of saturared nitrates or bromides solutions IIRC; the nitrate will lead to recombination of R and NO3 to allow for R-ONO2 (nitrate esters) and the bromides to a recombination of R and Br to generate some R-Br.
The nitrite was not mentioned probably because you would get tiny nitro compound and mostly nitrite ester that hydrolyses fast to alcohol and nitrous acid.
The question of another member was very interesting; if your video was correct; then the acetate would naturally lead to nitromethane, and any carboxilic acid would allow for easy mononitro and even polynitro alcanes (with organic polyacids); but it is not the case at all.
Another interesting aspect is the two e(-) process allows for alcoholisation in strongly basic (hydroxide) solution... a french youtuber has shown that it is a viable route for methanol preparation from acetate and NaOH in exces (vs the dry distillation of wood).
I have digged deeper into nitrocompounds and into nitrite or nitrosocompounds and I did find references that usually nitrocompounds do also form dimerization reaction of the Kolbe type because just like carboxilates (the R-CO2° is unstable and turns into R° + CO2; then two R° can join and form some R-R, and traces of R-CO2-R), the nitronates are also salts (but weaker ones) that can make dimers form R-CH(-NO2)-H --> R-CH(-NO2)° then 2 R-CH(-NO2)°--> R-CH(-NO2)-CH(-NO2)-R.
The chemistry behind is quite complex and depends a lot about the structure of the R and the vicinal groups arround the NO2 (probably for the stabilisation of the radical, their dimerization or their rearrangement)
There are many reactions unknown of the cloud that allow to reach nitro-compounds, nitroso-compounds and more without use of concentrated HNO3 nor H2SO4, P2O5 and that is why being a true chemist and understanding chemistry is an asset for me but not for brainless people wanting to hurt with knowledge (or lack of knowledge you know)

ty for a true debunk, also could you please link me the methanol production video, stp phliou
@@drNecronus
Two times I wrote a reply to your comment with the link and information and twice it was erased in one day (sorry for the dumbness of YT).
Better search on YT with as keywords "A fond les ballons" a video about electrolysis of acetate ("électrolyse") to make ethane but that ended to make methanol via Hofer-Moest a side reaction of the Kolbe electrolysis of acetate in strong NaOH base media.

Superbe rien à dire de plus !
any paper on this method? if it works i´d be interested in scaling it up to mass produce
I’d be interested in seeing that video
@ITC E-Man mmm i also blocked links but i should have at least seen it in yt studio. gotta wait until tomorrow for it to show up on my radar i guess
@@THYZOID I will check to see if I can allow them. Might be a UA-cam thing but I will if I can!
@@THYZOID Will check to see if I can change that permission
@ITC E-Man Use the DOI they are not blocked.
Well done again, this is another terrific step up in production quality, imma say easily your best to date and I’m super impressed! Blue play button was totally deserved.
Thanks! I’m trying to increase both the chemistry and the production both at once, investing in both! Very excited to be moving into a new house later this year and have good plans for a lab and a production space! Taking steps towards great things! Very much appreciate the support from everyone

Hi
Thanks for the video, how did you characterize the product as nitroethane?
Congrats on 666 subs, and now over 1k subs! Nice!!! Proud to say I've been here since under 500! 😃
Do you think that this electrolysis also works with Acetate to form nitromethane?
Is the nitroethane visible in the water after the reaction as little balls of liquid at the bottom of the container? Do you need to use platinum for the anode? Can stainless still be used for the anode? What is the optimum amperage per square cm of electrode surface? Can higher amperage per square cm be used? How large was the platinum anode?
I'm an amateur at best when it comes to electrolysis but I'd like to know where people are finding these recipes for making different chemicals, I've seen where they describe the process but don't say how much of each thing to add besides their electrolysis set up could be ten times as large as the average persons
*Nice RAMBO knife!*
Can you try reducing nitrostyrenes with Al + Ga? I’m so fricken curious if Hg can be eliminated
if your anode which doesnt need to be Pt was coated in CaSO4 it would act like a solid electrolyte similar to a salt bridge and stop oxidation byproducts at the anode.
I went down a little chatgpt chemistry rabbit hole not long ago. Hearing second hand how bad it is with some other subjects (law), I was sceptical. Thanks for giving this a go. Very interesting.
Isn't the react more like C3H5COONa+KNO3=C2H5NO2+NaKCO3 or Na2CO3 and K2CO3 so no gas bubbles
6:15 how come nitroethane does not figure in the right hand side of your equation?...
In the spirit of the end of this video and double checking, people are not infallible either: You set your current to 0.3 amps not to 3 amps. And in a later shot, where you turned it off, your supply was just set to 5V. I know because your current varied instead of the voltage.
DO NOT let chatGPT write the explanations pls. It's close but it's a technobabble fever dream. Electrons generated at the anode. WHat?? The "balanced" equations where elements spawn out of nothing and still don't create nitroethane? Yeah Chemistry With ChatGPT is the title but what's the prompt, what did it output? What did chatGPT write apart from the explanation? The one part it really shouldn't. Bruh
really clean method but is it really nitroethane i think you should focus on it, because i was wondering if it was nitroethane
Sodium propionate? I never heard of this for nitroethane
Interesting, i aksed chat gpt about this and it does not know about this procedure, so it's fake?
Do you have any real reference or true explanation? I can't find anything about it.
Olá amigo! Será que não tem como fazer nitrometano assim também??
I asked chatgpt how to break nitroglycerin emulsion, and he said that I have to boil the solution (wikipedia says it will explode)
great vid! can you make your audio louder next one?:)
Yes, this is EXACTLY the results id expect from chatgpt.
I played around with eith chatgpt and it gave me fake references. Its a cool tool but it wont be replacing chemists just yet.
The reaction scheme specially product side is one nonsense😂
Cool
Could sodium nitrite be used? Could calcium propionate be used?
Sodium Nitrite is a different path. Calcium propionate is easily converted to sodium propionate.
Can chloroform be made using electrolysis?
Electrolyze a mixture of water, salt, sodium hydroxide and acetone.
Chlorine will form at the anode, it will react with the lye to form sodium hypochlorite.
The sodium hypochlorite with the acetone will react in a haloform reaction to produce chloroform.
Can this work?
It doesn’t work to any reasonable degree, I’ve tried it a few times. You can use electrolysis to make your hypochlorite solution and then make chloroform as usual though. I’ve even tried using a layer of mineral oil on top of the electrolyte to minimize evaporation of any chloroform produced but never got any recoverable product. I think the hydroxide might be produced fast enough to destroy the chloroform as it forms, but that’s just a hypothesis. Btw, sodium hydroxide is produced anyway by sodium chloride electrolysis, there’s no real need to add more.
Are you sure you didn't make ethyl nitrate instead? Alkyl nitrates are dangerous, they are shock sensitive.
Dude where is the nitroethane fracture not shown in video if it's really nitroethane show us the fracure on 114c
Low efficiency. It is necessary to reduce the distance between the electrodes, and increase the concentration of potassium nitrate. The current should be between 400 and 450 milliamps. The temperature of the solution should not exceed 0 degrees, then the product yield will be closer to the theoretical one.
I prefer getting nitroethane from ethylene and nitric acid - a fairly simple reaction and the components are available.
don't you need a tube furnace for that? high temp vapor^phase nitration like is done in industry
Whyd you choose those 2 types of electrodes? Can you try to make a little more effort on product identification?
Platinum has more resistance to wear and tear as an anode, then graphite for the cathode as it’s cheap!
You're complaining about production quality just because he didn't say the types of electrodes used? Wow! That's a new one on me! I'd say you'd be justified in complaining.... If you had a good reason to, which this wasn't. 🤨🤦
@@BackYardScience2000 agreed! You can tell alot of effort was put into the video and I think he thoroughly did a good job explaining and identifying products and what was going on and it was easy to understand and follow. Dude it's been awhile since I hit you up. I actually will need to be getting some things soon. I hope life is treating you very well bro!
If it really worked, rhe nice thing is that the number of steps and waste was low.
The illusive nitroethane.
Mmmmm
I just subscribed. 666 is so magical number... 🤣🤣🤣
And a month later this dude falls out of existence.
Blink twice if the fedaboiz nabbed you.
ChatGPT еще и не такое расскажет, он не верные методы дает
This is absolute nonsense.
Duuuuuude, I wish you didn't shoehorn that music in. Ruined this video for me, had to skip the rest. Sorry, I think you did good otherwise.
