@Nurd Rage Secondary ethers, which dimethyl dioxane is, are much more prone to forming explosive peroxides. Some, like diisopropyl ether peroxides are known to be explosive even when wet. You should keep an eye more often on your DM dioxane bottle, especially if the sodium gets depleted.
Other than that, great video.
Chemical Engineer much more prone than what? Primary ethers? From what i know the stability of the carbon cation determines the likelyhood of the formation of peroxides. That means primary>secondary>tertiary. Or is my faint memory from school failing me?
I can work with primary ethers all day long as long as i dont expose them to sunlight or oxygen for too long.
Primary ethers. Although "more prone" may not be the best term for it, I'd say "generates more sensitive peroxides" would be a more accurate description. Diisopropyl ether is considered to form explosive levels of peroxides without concentration, and can explode without warning at high enough concentrations, and most info about its safety suggests to be tested for peroxides every 3 months as opposed to diethyl ether (primary ether) which is to be tested every 12 months. Though I'm not sure if DM dioxane would be as sensitive, since there's very little info about its hazards. Unlike di-iPr ether, DM dioxane is probably not as used in chemistry due to its sensitivity to acids, as opposed to explosive hazard.
explosives? Now i'm interested haha
Not the good kind of explosive, but the bad kind. The kind that happens after an unknown amount of time (weeks, months, years) and can destroy your nearby chemical stockpile as a BEST case scenario (not hurting anyone)
monster2slayer it depends on the relative stability of the radical formed alpha to the oxygen. So it goes secondary > primary and not possible with tertiary.
Damn I got all excited for a second, thought it said 'Dimethyl tryptamine'.
Can that be your next vid please?
i would be interested in him making that
May I ask you a couple questions?
1. Is it possible for you to establish water solubility in your DMDO?
2. Can ethers be stored with magnesium to prevent peroxides formation?
3. Can DMDO extract tetrachloroaurate ions like DIPE? Or, if not directly, their complexes with rhodamine B/methylene blue?
Really appreciate your work, hope you'll see my comment.
I feel omitted :( NR did the second round of replies to comments and I wasn't lucky enough to receive one. Notice me, senpai!!
Tyresio12 Haha, I know how you feel!

Thank you for listening to your subscribers and posting this. It would have been a shame to have the footage and not use it
Please make a video: How to use vacuum filters.
Get your vacuum line some water and some baking soda and then set up your glassware for vacuum filtration.
put 20g or so of baking soda in 200mls of water and then add it to the filter.
Then turn on your vacuum source, once on you can attach it to the vacuum takeoff adapter.
Once your are satisfied with the filtration and little to no more liquid can be pulled from the filter cake, remove the vacuum line from the takeoff adapter, (do not turn off vacuum before disconnecting the line from the apparatus).
This is less an issue with vacuum filtration as it is with vacuum distillation set ups because a vacuum filtration set up is still open to the atmosphere enough to create a much lower vacuum than that of a distillation set up.
You want to get into the habit of pressurizing a depressurized system slowly, I do this by carefully and slowly taking off the vacuum line in a controlled manner.
Alternatively it is advised to attach a stopcock system to your vacuum line that can be opened to the atmosphere that way you can slowly introduce pressure into the system.
Easy.
+jared garden A good way to do controlled depressurisation is to close the tap, disconnect the vacuum tubing and then place a piece of filter paper onto the nozzle followed by slowly opening the tap up; the filter paper will eventually gracefully fall off!
surplusdriller1 please leave
I just come to watch the magnetic stirrer bar.
surplusdriller1 shows how much you know, you call him names instead of explaining to him. Moron... that's not what the YouTube chemist community needs. Comments in these type of videos are for scientific questions/discussion/memes not hate!
I would super appreciate a series on the basics of organic chemistry labs, I know you're insanely overqualified but I'd love to watch it
Another unique contribution. Still waiting for a perborate oxidation of oximes into nitro groups, though...
Pwopelyne gwycol
LOL
How about using it as an alternative solvent for a Grignard reaction? I'd guesstimate good coordination properties with Mg ions.
Maybe add some more atoms and watch the reaction in the sodium reaction
Yesssssss. Been waiting for a new upload for ages!
It randomly occurred to me that a useful video for amateur chemists would be one on efficient, accessible waste management.
Just pour it down the drain in your kitchen! (kidding)
I once disposed of paint-containing organic solvent by slowly burning it in a jar with a wick. It was a nice and slow process, until all the solvent was gone.
I just found out that your VidMe channel is down, where can I view your more supidly dangerous experiments now?
It would be very interesting to see a video on the chemical traits of iridium.
Where do you get video ideas I am just beginning and am wondering how to find cool experements
Great video! I love watching this
YES! Finally!!
I have no use for it, but I wish I had all that glassware, I think lab glass is so cool
Can you make a video using nepthalene or moth balls.. m really finding out what can we do with it.. specially at home or for amature chemistry
How about Hoffman degradation
Have you tried polyethylene glycol (PEG) as the solvent for sodium production?
Try to extract stuff with it ! :D
50th :D
I like how you use otc chemicals really cool
How would you make sulfuric acid using this:
watch?v=1m0TQjBRcFo
?
Does adding nitrogen to hexane with some methyl groups synthesize dmt? please let me know, very important. It should work under high pressure with a catalyst.
How the fuck would that even work?
Isn't it risky to leave reactions running unattended for days?
Yes
You can get USP food grade PG from farm supply stores for around $20.00 USD per gallon.
DMT? :3
Is it good for grignard reactions?
I think you can use it but diethyl ether or THF are more convenient. Strongly polarized ethers tend to speed the formation of Grignard reagents so there's no much point in making this product for that purpose.
Dioxane itself causes a disproportionation reaction with Gringards, producing a chelated MgCl2 and dialkylmagnesium. The MgR2 can then be used for reactions.
Maybe if you want a slow reaction for some reason. Does it make sense to create grignards in situ?
We're early, bois.
Hey man i need your help .How to remove trace of nitric acid from home made nitrates.Mean left over acid in barium nitrate solution.Can i just boil BaNO3 solution and evaporate remain acid??
It's cool that you mention the properties and similarities with other products.
Is it anyway to separate magnesium hydroxide from sodium metal?
can you make laughing gass please ...
Was there other ways you could use before distillation to remove the water to speed up the process?
great video keep up the good work
Make a video on cleaning lab equipment
I mean your process is not the hardest to scale up, I reckon it's got potential !
I have ~1 gallon (less now) of propylene glycol for experimenting with sodium polyacrylate to make non-toxic freezer packs. I have some very interesting data (at least it's interesting to me!)
Интересное видео,успехов вам в дальнейшем.Лайк ставлю.
You're a nurd ?
your videos are fascinating i really enjoy them
How are your Lab Notes coming along?
You can get propylene glycol by the gallon from farm and fleet supply stores for $20-30. Used for ketosis treatments in cattle.
Perhaps something could be bonded onto the methyl groups to increase boiling point?
You need a longer or more complex glycol to make a heavier ether. Propylene glycol is already hard to find, the new starting material would be too expensive I think. And trying to change the dimethyl dioxane after formation isn't easy either.
François Bergmans Isn't butanediol relatively easily obtainable? That could be converted to tetramethyldioxane using the same method. I don't think other vicinal diols are easy to come by.
Or just get 1,2-butanediol and make diethyl dioxane
Or use something that has already been used as a solvent... Like say diglyme.
I thought we were making meth. Meh.
A birthday gift of a great video
How to make mercury from mercury oxide?

Yep, this is why Chemists always need a Bigger Lab - to store the stuff they spent hours making and can't bear to dispose of the product ;)
