I’ve found your videos and they’re incredible interesting but also they’re amazing to fall asleep to. I swear that’s a compliment 😂

Having lower yield than expected due to multiple recrystalizations is kind of a running theme in your videos, I love it

Hobby chemistry in a nutshell: "This synthesis uses A, B, C, D and E. The first four can be easily bought, but E needs to be distilled from F and G. F can be bought but G can be made by reacting H with..." Awesome to see you work through all these prerequisites throughout various videos though.

That orange juice looks pretty good.

4:22 instantly turning apple juice into orange juice

NileRed stands for “No, I Love Endlessly Recrystallising Everything Dammit”

I love how he's not affraid to say when something doesnt goes as planned, and also the fact that he will keep trying until he get the results he want while also showing previous fails. I dont even love chem that much but he makes it so interesting that i keep on watching more and more of his content

I have no idea what's going on in any of these videos, but seeing the little tornados bounce around in the beakers always makes me happy.

6:00 science diagrams that look like shitposting

Spf 3 is no small feat. You made sunscreen from scratch in a home lab, all by yourself, and it actually worked.

Wow, your videos are so much better now that I took an organic chemistry class. I actually understand what's going on! (mostly)

The 4k is so awesome that I can see all the filth on my monitor.

I'm in esthetics school and this demo for how sunscreen works with the beads is perfect to help students understand how chemical sunscreen works in absorbing the UV light. Thank you for your awesome videos.

You should make aluminium zirconium tetrachlohydrex, the main ingredient in anti-perspirant.

What the hell, how do I keep discovering new NileRed videos I haven't seen before? It's like Christmas!

Dibenzylidineacetone (DBA) is actually used to stabilize Palladium(0) in the form of Pd2dba3.CHCl3 which is useful for a number Palladium-catalyzed coupling reactions.

SPF 3 is a common absorption level for stuff like lip balm, so it’s not that bad

I remember while in the police academy, for 6 months I was staying up all night writing memos and I successfully watched every video you ever posted while I was writing. I love your videos brotha

I love watching your videos when I’m stressed out it helps me put my focus on something else and they are so relaxing to watch idk why😅I’m so happy I found them!

The mechanism is just too beautiful!!! Thanks for sharing!

I did this reaction in my organic chemistry lab class, and I used almost the same method you used in this video, although with some small variations. Our benzaldehyde and ethanol was analytical grade, and we purified our acetone (technical grade) through distillation (to remove water contamination and other impurities). That could explain why you had that initial cloudiness in benzaldehyde, probably your benzaldehyde was not so pure. To recrystallize the product we used the first method you used, hot ethanol (in the right amount to dissolve all the product), then we added room temperature water (while ethanol was still hot) until complete cloudiness occurred and then we cooled down the solution in an ice bath. Eventually we vacuum filtered the precipitate and dried it in the oven. My yield was 78,2% of raw product, 73,9% of target molecule (we analyzed it through GC-MS and UV-VIS). Not the best but I'm still and undergraduate so totally fine for me. My guess is, as you already aknowledged in the video, that you used too much ethanol and much of the product was still in the liquid phase, though your yield was not bad at all.

I listen to this when running

Dang, that's really cool! The demo at the end was really neat too.

In my research lab, we usually have a designated hood with aluminum foil completely covering the window, and protective eye wear when using UV light. Make sure you be careful, because it can mess up your eyes really bad even when used for a short amount of time.

Convert PET to terephthatalic acid and ethylene glycol! It's a simple de-esterification but it would be interesting seeing how you would get the PET to react with it being an insoluble solid at room temperature

To avoid canizaro reaction , you can mix the aldehyde and acetone then add the base slowly, so base attacks the acetone which attacks the aldehyde

There's more plot in the beakers switching out "conspiracy" than in the entirety of the Twilight series

When he was talking about the trans and cis stuff I wasn’t paying attention and thought it was a video about gender and stuff

Dude, these videos are SOOOO well made! :D

When I did the synthesis, it actually went nearly like the clock reaction you mentioned. I dont know why does it happen, but it is pretty cool. I add the acetone and then stirr, and suddenly a ton of stuff falls out of solution after like 60 seconds and the content goes from light yellow to brown-orange and looses transparecy. Really interesting.

your videos are so addicting I’ve been in a constant state of binge for hhhh idk how long

Another beautiful and informative video! You are great sir!

Thanks for the enlightening discussion of using water to help precipitate the product from ethanol. Much appreciated.

I've made this myself in our labs and it is a very fun exercise. It's fun watching this change colour when you keep it in the sun.

In this video he sounds so weary, like eternally tired.

These are amazing to fall asleep to, thank you

The test with the uv light is so cool!

I love how he makes jokes with a sorta sarcastic voice

Cool customized glassware!

Really enjoyed this!

This is the exact type of video I was looking to watch tonight. I’m commenting right when the comments are at 420 so I think the universe meant for this to show up in my recommended.

Omg I'm a relatively new fan and this is the oldest video of yours that's been reccomended to me. Your voice over sounds so different :o

jej HD! I can seee now! great vid as alsways nile :)

3:55 so that's how you make Mountain dew

Definitely invest in a 1 or 2 larger fritted funnels with different porosities. I really hated when I had a huge amount of stuff to filter and didn't have a larger frit. I have some larger 1 liter ones now and it was definitely worth it.

You explain things better than my university teacher

I wish there was a creator making videos like this now of this quality.

I love the 4k upload!! More 4k videos :D

Thanks for yet an other great video... :-D

Dibenzylacetone can also be used as an organic photosensitizer in certain photochemical transformations!

Five years later and these videos are still solid

Really nice to see this after hearing all the diy sun screen horrors since I started getting into cosmetic chemistry lol

toooooo gooooood you are awesome man

Muito bom o vídeo!! Arrasou!

NileRed signature laboratory glassware line!

ALMOST AT 100K SUBS :D Congratulations !!!!!! Been here since 8k subs :3

Some of the benzaldehyde tried to precipitate out when it came into contact with the bit of water in the ethanol. The molecules quickly re-arranged themselves and dissolved in the ethanol afterwards.

Ahhh I love KZfaq. I always know when it's been a month and a new nilered video is incoming, because I get recommended all of his older vids xD

One use I can think of is as a ligand for palladium catalyzed coupling reactions

Awesum video keep it up!

OMG sir, where have you been all my chemical life !!!

woah Nigel sounds way more nonchalant in older videos. I kinda like it

i must say nile's voice is asmr

I would love to see a video of yours on how those resins harden under UV light

You didn't seem too impressed with this video during the commentary 😕 maybe something was on your mind?

Watching these videos studying in the 12th grade and being able to relate to most of the reactions is really fun

I like your work Continue

I am doing a research on the synthesis of dibenzalacetone, do you still have your sources? if so could you please share? Thank you for the video anyways

Any good KZfaq channels on intro to chemistry? I've found your videos very fun to watch, but I want to know more about the processes involved

Lol I love how many people watch his videos theyre literally just chemistry yet so entertaining, maybe Im a bit of a nerd and love cience related content but most science channels dont get this many views I feel like

I misread this as “subscribers”. Literally thought the madman was synthesizing more subs to the channel.

How do the UV absorbing capabilities compare between the trans-trans, cis-trans, and cis-cis stereoisomers? Does one make a better sunblock than another?

That stir bar is fucking vibing

20 K views, zero dislikes. Pretty good stuff.

I watched this whole vid just to see how you tested the final product.

Nice video😊

I would love to ask something... I went through few laboratories at our university and we never put the watchglass on a beaker during recrystallization... The true is, that it was almost forbidden to use beakers for reactions, heating and so on... We could use it just for our solutions of acids, bases and salts. We were using just flasks for almost everything. I just want to ask, why there should be watchglass during recrystallization... Thank you for answer :)

Great as usual. However, I did notice one error: the reaction you give for the synthesis should produce two water molecules, not one. Also, since you said that crystallization needs to be slow in order to be effective, and your failed first attempt apparently took a while, what do you think about your second one producing much better results after just three minutes?

You should make a channel for all the small experiments that you do to make the bigger ones, like prepping the chemicals

If you put a vial of dibenzyl acetone on a zinc sulfide screen and exposed it to UV, do you think you could see a "shadow" in the phosphorescence? You could compare to a blank vial of solvent, a sample of commercial sunscreen...

good channel, good vid quality.

the thought of dissolving something without a stir bar manually by glass rod are the biggest nightmares of chemists

@NileRed my Naoh from where i come from at least comes with these annoying aluminum beads would those afffect anything like should i seperate them or do the have no effect i already know that there is sodium aluminate being produced so does that affect any reaction ??

im wondering if the cloudiness was because of the 5% of addatives in your ethanol to denature it perhaps?

This channel should be used in chemistry classes.

that Moment when u get really exited cause u got a KZfaq notification for a new nileRed vid but then u realize u already watched it on patreon XD

Sometimes I perform what's known as the Arnold Palmer reaction and I react lemonadeythl with iced teaoxide, yeah I know I'm a chemist.

I want the forbidden orange juice

Him Alpha hydrogen Mean intellectual:Chad hydrogen

Am I missing the link to the older video that you mentioned putting a link to?

Have you got a Kofler bench for the m.p.'s? :)

3:59 Reminds me of two things moutain dew and piss

please do a video on your lab, and where and for how much you got yourr lab equiptment.

But does it have a nice matte texture? Does it sit nicely on the skin? How often will I need to reapply it?

Ive made this last year in my undergrad organic chem lab

How long does the dissolving step usually take before the crystallisation step?

this is a great channel to watch when you need to fall asleep. i fall asleep instantly because one im not smart enough to understand anything he is saying and two like math? my minds like nah nah

Please do a video about synthesis of "Testosterone Enanthate" using Marker degradation. It seems easy creating one using Yam cholesterol but I just cant figure out

Welp just when you THINK you have an original comment to post then see it's been posted over and over and over 😂 well at least we know he has some pretty freakin decent playtime or whatever it's called for KZfaq...this is also my go to for background noise while doing work or having meetings..but.. Especially from falling asleep to these, watch it for hours! ❤️

I searched for sunmade home screen and found home made sunscreen 😄🤣
