Extracting the World's Most Popular Psychoactive: Caffeine

[@florianstuder3128]

thank you for the subwaysurfer integration really helped me getting through the boring number part

[@BackYardScience2000]

That last skit at the end had me rolling for some reason. Again with the sudden flash of memories. 😂😂😂😂😂

[@WheelerScientific]

Can you tell I’ve never made lines before? Lol

[@williamneubecker]

@@WheelerScientificlol yeah that’s pretty clear (Probably a good thing). My eyes started to water watching you try and wrangle those huge lines on salt😂

[@danielgreen6302]

@@WheelerScientific Hey Silly Question is it really true that why tea caffeine doesn't really effect you due to a certain molecule. If so or not; Please explain or if you are indisposed I understand, Thank You for reading regardless.

[@BackYardScience2000]

You saying the boiled tea leafs smell like fresh cedar wood really brings back memories for me. Me being a logger by day, it *really* brings back memories. I love/hate that smell for many reasons.

[@megumin1582]

is NOONE gonna talk Bout how he flexes lab grade meth and coke at the beginning

[@no0n34ta1l]

Thank you Sigma-Aldrich very cool! It even expires in the 2020's lmao it aint even old shit

[@manyshnooks]

These are analytical samples, the DEA and enforcement don't even care about them as there is only a trace amount in them.

[@strade601]

To get rid of the annoying filtration step (and possibly increase the yield), you should try a Soxhlet extraction if you got the glassware. Using boiling benzene as a recrystallization solvent also greatly helps getting rid of leftover tannic acid.

[@Godwh1sperer]

Dear green chemist: you can simply put coffee into boiling water, filter, boil it down and then stick it in the fridge to get a whitish precipitate of mostly caffeine. You dont need dichloromethane, just coffee, water, a source of heat, a filter and a source of cold. At room temperature, 1gr caffeine dissolves in 50ml water. At the boiling point, 1 gr dissolves in just 1.5ml water. You can directly crystallize from water then recrystallize for purity, no chemicals needed.

[@philouzlouis2042]

Hi Wheeler Scientific, Nice video. About your caffeine extraction, you could use a better technique than wet extraction "à la tea making" via a Soxhlet apparatus. That way boiling clean solvent into a closed loop recirculates, condenses and falls on top of your leaves; thus extracting a good quantity of leaves with a finite quantity of solvent. This can be done with CH2Cl2 or with H2O. Regards, PHZ (PHILOU Zrealone from the Science Madness forum)

[@tracybowling1156]

I HATE caffeine. I do not like the way it makes me feel. I wonder how many people feel the way I do? Anyway, your video is very interesting as usual! 😊

[@watterztrail7870]

How does it make you feel

[@noelswedzinski4498]

The Subway surfer tactic had me rolling,😂😂, I wonder when code channels will implement this method.

[@anthonyrickardii6198]

That’s pretty awesome! You should try with Solanaceae

[@성이름-d4o4o]

Caffeine should be great NHC precursor

[@nikoivan2580]

How many mg of caffeine you want? Yes.

[@infectedrainbow]

What you did with the game while analyzing the data. That was...incredibly helpful. Is there a name for this?

[@MrYellowOffical]

What are thesse weird stoppers or Joints called in ur Destillation?^ And btw is this ur Home Lab?

[@ltsgobrando]

The last scene had me laughing so hard! For a few reasons... mostly cuz of how terribly it was done (being able to cut lines is *NOT* something a productive member of society should know how to do) As a recovering addicted, almost 3 years clean, it really tickled my funny bone. If you pulled 4 equal lines off the pile holding your razor at a 45° I'd have questions.😂❤

[@allenbates3470]

so does crystallization occur in an 100% pure form?

[@WheelerScientific]

Chemists rarely say its 100% pure, so it recrystallization is just used to increase purity, and not all cases of recrystallization even come close to pure. As some chemicals undergo co-crystallization. Let me know if you have any other question or clarification.

[@GorVala]

Sugar is a drug 😂😂

[@RitikKumar-zh8fm]

Hello sir how make iron+antimony star regulus pl. Rep.

[@EgonSorensen]

After going keto-diet, I found out that dark chocolate contains about 1/3 its weight as natural caffeine - and I didn't sleep much that night. Apparently it has other psychoactive properties too :ø)

[@salimshady6100]

Recrystallization for the winnn😤😂

[@GorVala]

Get caffeine pills, problem solved 😂

[@bkgaming9174]

That’s not really the point

[@watterztrail7870]

Caffeine pills still have a bunch of other kinds of compounds inside of it so it’s not all 100% caffeine If we wanted to get that caffeine out, we’d have to go through a similar extraction, which would result in a higher yield of caffeine

[@Dr.Agent.420]

Bro had to pull out the subway surfers

[@Correct_Opinion]

Very cool

[@GorVala]

What about that Cracain 😂😂

[@lel7531]

Subway surfers ? You got to be joking

[@WheelerScientific]

It was indeed a joke...

[@deamoneater357]

You can make a pseudo crack with caffeine.

[@mistercornell4755]

your my favorite druggie

[@Spubaru4U]

WTF is up with the train game?

[@markedis5902]

Sintering not sinIStering

[@squizitzithatsitalianforyu4782]

Squizitzi that’s Italian for yummy 😊

[@h7opolo]

11:03 "samples that were RUN", not "were ran". omg.

[@neb_setabed]

Thumbs down for the add subway surfers bullsh*t . If you continue to do that, I'll unsubscribe

[@WheelerScientific]

It was a joke. r/whoosh

[@garrettmillsap]

Fkn crybaby

[@charwest5892]

Why are you mentioning cocaine and methamphetamine at all?

[@rosez2980]

Because they are both stimulants like caffeine. But obviously much more extreme.

[@tommustacheless4679]

Most popular substances along caffeine and nicotine

the real question is why aren't you

[@TracyGolman]

We all know meth and coke are stims but some people do not know caffeine is a stim

The lines lmfao dare you to do one for science ofc 🫡
