- SeOCl2 - Selenium oxychloride. It's closest relative of thionyl chloride. This liquid has better dissolving ability towards most non-metals and other substances. In this video I'll show the synthesis and chemical properties of selenium oxydichloride.

4:05 im so used to distillation setups being filmed with the receiving flask on the right that i got confused by what i was looking at.
What kind of deviant collects the distillate on the left? 🤣
Yes me too 😊
This is so strange. I didn't even think that left to right convention applied to situations like this!
Can we all appreciate the terror this poor white surface has endured for the experiments shown here?
Just gonna say your videos are S tier in every way. Totally awsome for chemistry teachers especially on the first or second day of class. You definitely put the wonder back into chemistry.❤
The slowed clip of the test tube reaction demonstrates the gas generation of hypergolic propellants quite well in a way. Love the niche chemicals and unseen reactions!
Also, found your channel through the explosions&fire collaboration you did. Needed more after watching his second channel lol
For your watch glasses, may the new ones have the same flawless sense of comedic timing as the ones that broke here.
Thank you mate! This is enough for a dozen glasses!
Ah I have been looking for the appropriate solvent for all the selenium i come across in my day to day life 😂
Seleninyl chloride. The very name is enough to make anyone who knows any inorganic chemistry shudder. From someone who worked with thionyl chloride.
I even couldn't tell if SeOCl2 has any practical applications. SOCl2 I remenber well as a versatile chlorinating agent, with the big advantage, to form only gaseous side products, compared to PCl5.
It is toxic in every imaginable way 😮
Yes - the whiff I got of hydrogen selenide when experimenting as a kid was enough for me! Gotta have an excellent fume hood.....cheers.
I still think azidoazide azide wins the gold for 'chemical names that scare chemists'. I almost expect my keyboard to explode from just typing it out.
Shh, naming it sets it off @@OrqwithVagrant
Quality + consistency ===🔥🔥🔥
Yellow chemistry, nice!
Tom from Ex&F punching the air as we speak
Your channel should have way more subs than you have. Great stuff!
Why is this so fascinating to watch?? It blows my mind sometimes how chemistry works. When you see dangerous sodium reactions and see how dangerous chlorine is and then realize that the 2 together are edible as table salt is just the craziness thing. There are so mant chemicals that don't play well with each other and others that go from deadly to life sustaining. It's endlessly fascinating.
Someone buy this man more watch glasses... That burning P(red) glass flying past was priceless.
Did that tellurium solution at 13:39 eat through the test tube?!
I think its just the glass bar smashed the bottom of the test tube.
The fly at the end 🤣
Dude is like "Seen this camera. Gotta go!"
Please dont stop love those scientific reactions i learn so much ❤❤
i once bought a few grams of (not pure) selenium and tried to melt it, it liked to form thingies shaped like "rupert's drops" but the most interesting part is when i got the temperature too high and got scared and then blasted water into it, it blasted with a huge cloud of orange vapor that smelled like garlic and radish combined... thank god i don't have any more 😅
I remember it looking more like red blood cells than rupert drops
Man I sure would love a collaboration with Nile Red, Nurd Rage, Explosions&Fire/Extractions&Ire, THY Labs and all the other kickass chemistry channels, all of you combined would create a hell of a show...
Either way, collab or not, this channel never disappoints.👍
Nilered has gone down a different path. It's not a good channel anymore.
Never disappoints
To be honest, I was waiting for the fly to be dissolved...
You must run a business to have access to a lot of these chemicals, or be part of a big research lab.
SOCl2 is Cat 3 chem weapons schedule, highly controlled in the UK, US and EU
Yay now i can make diodes that smell like farts when they fail!
I LOVE YOUR VIDS CHEMICAL FORCE!!!❤❤❤❤
Love the Cobalt pentahydrate colour
All your video are the best on the net thunk you very mutch
Thanks again for a great video!
I like seeing your syntheses included. . So that's the Selenium analog or Thionyl Chloride, without the lovely property as reagent of gaseous byproducts. Interesting inorganic solvent. Could have some applications in electronic and photonic fabrication.
I thought the fly would also take part in a chemical reaction :)
Well that stuff is terrifying!!!!!!!!!!!
👏👏👏👏👏👏👏👏 Loved it!
Yes more Please!
I bet those selenium chlorides smelled incredible
Thionyl chloride is bad enough as it is...
Awesome!
As always an amazing presentation, thank you! And @10:00 the cobalt chloride hexahydrate looked quite tasty like raspberry ice cream ! What happened @13:45 ? Did the glass dissolve after the reaction of tellurium with seleniumoxychloride ?
Pretty cool. I wonder if there is some solvent that would dissolve silicon. I know water+HF+Nitric will dissolve it, but that is a bit scary.
In the case of selenium, the point is that you can evaporate this solvent and get the substance originally dissolved in it!
In the case of hydrogen fluoride, you no longer get silicon only its compounds
@@ChemicalForce the most amazing thing about selenium oxydichloride I find -- is the thing that it can dissolve selenium and arsenic, antimony and tellurium irrespective of their allotropic state :)
there is no heroism in dissolving red selenium or yellow arsenic, as CS2 or even a boringly standard toluene / xylene can do that too :)
but being able to dissolve their metallic forms, and even being able to do so to heavier & less soluble tellurium and antimony -- is truly amazing :)
Thank you so much. Can the procedure be modified to produce sulfuryl chloride? I understand one is a dioxydihalide, whereas the other is an oxydihalide. Just curious if such is possible without substantially altering the apparatus/reagents.
Are there any chemicals you don’t have!
😂😂😂
Hydrogen astatide
While it’s safe to assume that carbon in the form of graphite or diamond does not dissolve in SeOCl2, I do wonder how well fullerenes (e.g. C60) would dissolve.
@ChemicalForce Can you do some experiments with Tellerium, please? 🤔
What would happen if you added seleninyl chloride to phosphorus under an inert atmosphere?
I don't know why but I think it's hilarious to say I am guessing it would make big boom big big boom but yeah I doubt it honestly that would be a very good question for a very interesting experiment I'm curious to know how other substances would act in the same way
Probably Phosphoryl Chloride compounds, if you mix in other things, it is actually used to make Organophosphate pesticides and nerve agents. I won't go into detail for obvious reasons.
hey I really really love your videos sir! I wanted to say. The footage and explanations are so amazing. I love your channel a lot.
Inquiry:
10:12
At that time stamp, you said thionyl chloride can dehydrate cobalt dichloride hexahydrate to the monohydrate, but the chemical equation shows 5•H20 hexahydrate.
Does it remove just one •H20 to make 5•H20 pentahydrate? Or does it remove 5•H20 to get to the monohydrate? Thank you for your time sir.
Thank you for sharing these videos! I appreciate the knowledge and time.
That endothermic reaction example w thionyl chloride and cobalt dichloride •6H20 was amazing! 😮 Very uncommon!
Yes, watch my video about dicobalt octocarbonyl, there is this reaction in more detail
@@ChemicalForce thank you sir!
11:58 SeOCL2 + N2H4 = H2Se + N20 + 2HCl? idk though, it looks like there's a bunch of red selenium as a reaction product
Maybe SeOCl2 + N2H4 -> H2O + 2HCl + N2 + Se ?
Great video, and great reagent!
I'm curious whether there is any solvent in which carbon can dissolve (not counting alloys, but the same type as dissolving, for example, sulfur in toluene?)
It depends on allotropic form of the carbon 🙂
Fullerenes can easily be dissolved in carbon disulfide or in aromatic solvents (benzene, toluene, xylene etc), somewhat less -- in carbon chlorides (tetrachloride, chloroform or DCM) or in acetone
@@RomanBekker2022 Thank you, I didn’t know this about fullerenes) I really should have clarified the allotropic modification, I meant graphite
@@alexsmit9554 I don't know anything that can really dissolve (not "chemically react and destroy", but truly dissolve) elemental carbon in its graphite or soot form
(excluding of course molten iron to some extent; but alloys are other theme than liquid solvents we all talk of now...)
very kul
Chemistry most can only dream of mixed with art and photography.
we use sodium sulphide na2s in our effluent treatment system to remove/lower the amount of heavy metals, expensive stuff, but we dont want high heavy metals going to sea.
What about berilium . Can you synthesis a liquide molécule with oxygène
Google captions read "Fanny Chloride" randomly.
Found "all natural" bathroom cleaner at discount overstock store. In fine print, it warns it may dissolve porcelain. Wonder why so much was on clearance rack?
hello from the northwestern hemisphere.
Strong "everything here is nasty and wants to kill you" vibes
Now do it for Tellurium....
the last reaction Te+SeOCl2, why? I think of Helium superfluid
was quiet surprised to see that thionyl chloride isnt reacting really violent with water.
and what was the capilary tube in the vac distillation flask? i didnt get that. Did you pull the vacuum through the tube? why didnt it suck into the tube then?
Best regards
I too want to know what the capillary was about. Vacuum appeared to be pulled at the receiving flask end like normal (pink hose) so it wasn't for that.
What I find fascinating is that silver is THE element that really hates being in solution.
Main group chemistry go burrrrr
I wonder about the exhaust processing into environment
aka .. protect your lungs
I can smell this through my screen
What music at 1:25?
5:38 - You should list your Patreon levels in terms of how many watch glasses/dishes you can get :D
Hopefully, you bought that 144 or 1000-pack.
does it dissolve carbon ?
hello from romania !
I bet the ducting for your fume hood is full of straight up nightmare level chemicals 😱😳
“add some anhydrous hydrazine” 😳
Selenium is crazy.😭
Yeees
0:58 The text he says is wrong, but the equation is right?
What I say is true and the equation is correct
bruh why does the background music sound like the intro of Tagesschau?
Probably SeOCl2 + N2H4 ----> Se + 2HCl + H2O + N2
I know it smell crazy in there
Carbon Diselenide
My tiny social life could not stand a blow from becoming very smelly because of selenium or tellurium traces in my skin. I refuse to play with their compounds. :)
I am never working with selenium anything ever again ha
Another awesome video thanks for sharing
Better than any modern abstract art.
