how to extract coke from coca-cola?

This is exactly how I make my coffee every morning.

Extract sadness from my heart

In an unprecedented turn of events, Nile uses a coffee filter to filter coffee.

Two points I gotta make: Don't be afraid to use extra water for the coffee bean extraction- you can always reduce down by boiling (caffeine is pretty hard to burn, you'd have to get it past 235C to even think about it). Also I feel like drying the DCM was largely unnecessary and even harmful (the salt water likely stole a significant portion of your yield). Since you are drying your solvent with heat, why worry about having an anhydrous solution?

My thesis is literally about extracting caffeine from coffee and this suddenly came up in my recommended. Thank you RU-vid

Using a coffee filter for its original purpose. How ironic coming from a chemist

You can boil the coffee in sulfuric acid (to free it from it's acid-bound form), make it slightly basic with NaOH and extract it with chloroform instead of DCM (both work fine probably). We used that method at uni.

"Do you want milk or sugar?" "No, just come sodium carbonate. It really brings out more flavor."

Did this at school in the 1960s but used a large catering can of Nescafe instant coffee. Got quite a lot of caffeine yeild out of it which went very well with the moonshine alcohol made from fermented and distilled sugar and yeast. Hell of a party that weekend.

Do your neighbors just think your cooking meth?

Chemistry is fascinating. The entire time I was wondering whether the dichloromethane would be removed, and if so, how. In the end, he just heated it up because dichloromethane has a low boiling point. Fascinating that it's possible to do all this mixing and removing!!!

Extracting nicotine from cigarettes please!!!

Neat to see these early videos when he's still working on his eventual catchphrase, "Honestly, the yield is pretty bad, but I still have more *blank than I need."

Years ago, my brother bought a 1 kg tub of pure anhydrous caffeine so that we could caffeinate just about anything we chose to drink. This experiment gives me a special appreciation for the processing that went into that.

I am begging you man. Please upload more frequenly. I couldn't find anyother youtuber like you. Your vids are neat, professional, educational and not sloppy like many other channels. Please upload more frequently. I love your vids. Keep up the good work

Nice video! One thing you might want to look into is to simply grind finer. In the coffee community the consensus seem to be that after a certain size only the exterior gets extracted - that could explain the low caffeine yield.

great, now i got a neet snortable form

What the video is aimed to be about: Extracting caffeine from coffee What the video is actually about: How to make Decaf coffee using chemistry

I feel like there is a fine line between the right amount of caffeine and productivity since working faster doesn't always mean that the output is as productive, but it is some what better to have coffee but not specifically multiple cups a day

Oh I get it then you snort the caffeine!

I really thought that said "How to extract cocaine from coffee."

Nice video! We compared caffeine content years ago at varsity on different beverages. Contrary to popular belief, a shot of espresso had the lowest caffeine content of everything we tested (lower than tea, instant coffee and perculated coffee, etc). This was mainly due to the short infusion time when extracting espresso from the machine (20 seconds). The type of roast also influenced the caffeine content - the darker the roast, the stronger it tastes, but the less caffeine it contains due to longer roasting. So if you want to stay awake, leave the espresso and opt for a weak tasting, but "powerful" pale roasted perculated coffee.

how do you extract cocaine from cold pills

I think part of the problem in the low yield may be that the brewing technique that you used didn't get all of the caffeine out of the coffee. I say this because it has been found that properly brewed pour over coffee (which is effectively what you were doing) has a higher density of caffeine than espresso.

"The coffee filter separates the coffee grounds from solution" well....

Clicked on this video thinking I could go into my kitchen and have something cool to do for an hour... Was wrong

You've inspired me to go back to my college chemistry book and to dig around

Can you snort the caffeine? Asking for a friend.

Copy paste Put in 10g of coffee into a container followed by 4g of sodium carbonate, then add in 60mL of distilled water (increase amount of ingredients for larger quantities) , and then bring the solution to boil for 15 minutes, stir or shake occasionally to prevent it from foaming over, or turn down the heat to simmer, once the 15 minutes is over you can let it cool but make sure to keep the temp as high as possible, and then strain it in a coffee filter, and then add 100mL of boiling distilled water, then pour the mixture into a separatory funnel and then add 15mL of dichloromethane, and gently shake it around, after that pour out the DCM which has the caffeine in it, and repeat the process with the remaining coffee, and then pour the DCM into a clean separatory funnel along with a saturated salt solution to pull water from the solvent, and then gently shake it again before pouring out the DCM, and add in drying agents like molecular sieves and dry for 20 minutes before placing it into a new beaker, and the boil to remove the DCM, but don't overheat it as it will burn, and then, once dry, recrystallize the remaining substance with a 95% ethanol solution, and then let to rest in the freezer before vaccum filtering and letting it dry in the vaccum for a few minutes.

feeling like breaking bad

Extract smart from smart water?

perfect.. i recommend this video to every student who looking for this topic

how do i extract codeine from syrup

0:29 This is opposite of clickbait... you are straight away telling the audience that this video is almost same as other one... That's why I love this channel... I am still gonna watch it... 😋😋😋😋😋

In my school canteen they used to add sodium carbonate to the tea to make it stronger. At that time I used to think that was an urban legend. Years later I'm learning it can actually make tea/coffee stronger!

Please do death wish coffee since they claim to be world's strongest

can i snort this?

Most people wake up with a glass of coffee in the morning. I personally, just snort a line of pure caffeine.

My mind kept reading “cocaine” instead of “caffeine” on the thumbnail and I was so flabbergasted by the information that coffee could really contain cocaine that I had to open the video, only to discover how dumb I am.

"Quick! You're late for work!" NileRed: "Wait, lemme take 40 mg of caffeine real fast"

This would make an excellent chem lab project! Coffee, simple-ish process, and of course, and inexplicably low yeild that you have to explain using BS in the final report! I should tell my former college’s chem department about this lol!

3:17 AM. 'This will definitely let me pass my exams tomorrow.'

I just wanted to make my coffee strong but this dude went all Breaking Bad on me.

Nile in 2015: One hundred milliliters Nile in 2021: Hundred mills

the yield is low because folgers isn't real coffee.

Aight now I can snort pure Caffeine and use it because I'm to broke for coke.

One trick I learned years ago with coffee is hold the filter firm with one hand and sharply tap the side of the thing with the other fingers, a sharp rap will make the water go thru faster.

Can you show me how to extract money from my bank without them noticing? ✌🏼

This was really well explained. An interesting video would be one on extracting the alkaloids from tobacco. WTA is hard to buy and it would be good to see how hard it is to make.

*Normal people at 7 am:* man need my coffee *Me at 7am with my beer:* huh. Coffee. Hm.

The new Deconstructed Coffee. People are going to be asking for this at cafe's in the future.

1 shot of Espresso (10 grams of coffee grind -> 15 grams of liquid) contains about 30ish mg, so your yield is pretty damn amazing tbh.

How to extract caffeine from energy drinks.

You should try this experiment again with chloroform as the solvent. I am planning out the experiment and still have to make more chloroform. Caffeine is apparently 2 times more soluble in chloroform than in DCM. The only downside would be the fumes from boiling, but you have a fume hood. I think it'd be interesting since basically everybody uses DCM for caffeine extractions. Well, I tried it with caffeine pills and it worked really well. I got a relatively low yield because I was sloppy and a lot of the caffeine was lost on the walls of the containers after the chloroform evaporated off. I didn't have enough chloroform to do proper washings. Still ended up with about 8 grams of impure caffeine. I'm going to recrystallize it from water tomorrow.

Its fun turning caffeine powder into caffeine-citrate. For me it had less of the known nasty sideeffects.

I remember this experiment when I was in Organic Chemistry. It was actually our first experiment. It was super fun. ^_^

So, can I snort it, and it'll still make me poop?

i have a theory for an at home crystalization, step 1 should follow brew 1 pot of strong coffee, a big pot. step 2 take the probably cold coffee and evaporate most of the water off, if you filled up the brewing pot with coffee, then reduce it to a quarter of that if possible, it will probably start to burn the bottom of the pot if not constantly stirring, step 3 after reducing the amount of water freeze the pot of coffee in the freezer till frozen solid, after being frozen solid stick back on the stove and heat it back up till its all melted, this entire step should be done in a stove pot along with the evaporation step, step 4 mix rubbing alcohol into the solution, if you have a quarter of the pot roughly, mix a quarter of a quarter of the 90% rubbing alcohol into the pot, stir then pour the pot into a clear column of some sort, like a graduated cylinder but a vase without numbers and is used for plants, or a graduated cylinder works if you have that, allow the layers to seperate, if they dont it fucked up, 75% alcohol does not work for caffeine extraction, the alcohol is indistinguishable from the water, ive tried doing this with pills, i have a 2 gram water bottle waiting to be done something with in my room, 90% iso propyl alcohol should work, 99% is the best, mix and if theres 2 definable layers, take the clear one and boil off alll of the alcohol, which is kind of dangerous so do outdoors, pretty sure all alcohol vapors are toxic in some form whether inebriating, or lethal inhalation so work safely, after boiling you have uncrystalized caffeine an unkown amount, it should be more because its a brewed pot of coffee, you could even just cool and heat the alcohol solution a lot and it could crystalize, or allow it to sit in a still environment for a very long time, i had a water bottle in my room with equate DXM guaifenesin pills mixed into it, i let it sit for 8 months and when i was going to throw it away i seen all of the FINE crystals at the bottom of the bottle, and when i flicked it, crystals fell from the top of the water, i believe the DXM hbr isolated itself and crystalized out of the water, its EXTREMELY bitter and has a faint extremely faint odor that i would associate with the chemical guaifenesin, but when I did a heat test on tinfoil to test whether it was guaifenesin or dxmhbr depending on how fast it burnt with the lighter under it and it burnt up quite fast, the smell was im not even sure, the smell makes my brain wonkey when i think about it though, its definitely probably DXM.

How to extract pseudoephedrine from paracetamol.

IT'S LIKE HEISENBERG TEACHING ALL OF US, HOW TO COOK METH

Hi NileRed! I've recently been using a supplement called licorice root; but it has glycyrrhizic acid which poses some health problems with long term use. There is such a thing as a deglycerrhizinated licorice root. I've recently procured pure licorice root powder and I wanted to know how you would deglycerrhizinate it in the lab. Thanks!

10g coffee: checked. 4g sodium carbonate: checked. 40 ml DCM: *dammit!* ;\ BTW how do you know that this white powder is really just a pure caffeine and not some other similarly-looking stuff mixed with it?

This seems appropriate to watch now that I’m sipping my afternoon coffee

Quantification of caffeine is something everyone has to do at the university for pharmacy. All in all the method is pretty much the same, except you do have to shake it a good amount. You said that there is a possibility to make an emulsion. Well thats true, but the emulsion is not stable and will disperse again after a short time, overwise use a bit more DCM. You can also cook the coffee for a longer time, those 15 minutes are not enough. Also try to invest into a Rotavapor, just cooking DCM is not a good idea at all (I hope you got some air-filtering unit above it or a digestor). We use Sodiumsulfate instead of a molecular sieve as drying agent for the DCM. We didn't recrystalise, because we made titrations with it. Reason is also because its purity won't be that good (far from 99%). Cheaper to just buy the pure caffeine from your trusted merchant / pharmacy. but nice vid!

This dudes such a freakin nerd. I love it.

The last bits reminded me how well my dmt extraction went :o

I vaguely remember extracting caffeine, from tea, using a steam distillation step, followed by a precipitation step using lead acetate. Final purification was sublimation in a heat pistol thing.

you could try using robusta instead of Arabica coffee. because robusta contains more caffeine

How does the food industry extract caffeine from coffee?

I was scrolling fastly, I read cocaine instead of caffeine in the title

You could just buy half a gramm pure caffeine from your local "coffee-shop" aka the place you get your bongs and papes

Was wondering why everything looked so familiar. Realised I've tried this before at school. We used bottled coffee

i’m literally doing this in my org chem class rn what also thank u to this channel for single-handedly inspiring me to major in chem engineering next year

Is it possible to extract L-Theanine from tea? Love your extraction videos, thanks!

snort it

so this is how Nile gets his stuff legally

Please extract THC from Cannabis

lol when you start with 10 grams of coffee, of course you're going to get a pitiful amount of caffine. Use the whole can!

When life gives you coffee, extract caffeine.

The lighter the roast, the more caffeine content. Medium to dark roasts are roasted longer and as a result have more caffeine burned off for a more full-bodied coffee experience.

"I'm just gonna go ahead and blame Folger's" is how I'm going to react to anything wrong in my life hereafter.

Shall we taste that...?

will you do a video where you sinthesize it ?

To expedite the filtration and minimize coffee loss I would recommend dampening the filter with DI water. Wet it after you begin brewing and it should be damp but not soaked.

how to make cut for cocaine. thanks.

I will TOTALLY not abuse this information.

10 grams of coffee makes how many cups of coffee? If it's about one, your yield seems pretty great. Periodic videos extracted caffeine from 6 cups of coffee and got around 100 mg. That's about 16.6 mg per cup for them, your 30 mg looks like a much better yield. Unless they had an unusually low yield, your yield seems a lot higher.

would there be an advantage to using a soxhlet extractor for the coffee

wow so thoroughly honest

Does it feel like cocaine when snorting that?
