Caffeine Extraction from Tea

[rocketpro22]

But if it's toxic, and you can't use it, then why did you make it? It seems kinda pointless.

[meeatfood2]

Now snort it...

[askar4kill]

Pure caffine is white, u must have done the exp wrong

[MisterNickOtine]

now do nicotine...nah just kidding : )

[Aazerel]

Where are you, like on a boat or something?

[MrTechGuy1995]

Ethyl acetate? That is a reasonable substitute for what you are using know.

[Dudethatstrippin]

why take the caffeine out if you have no intent to consume it???

[yellowmetalcyborg]

You could sublime it, NurdRage style!

[hawk1buster]

Try doing the same thing with Tobacco....see if you can get an extract.

[DoktorKlawonn]

A nice procedure!

Will you try to purify the caffeine? Perhaps sublime it?

[ReactionFactory]

@DoktorKlawonn

We have no plan to, because we have no real use for the caffeine anyway.

[DoktorKlawonn]

@ReactionFactory

Oh, it's a pitty then you didn't recover the chloroform

[ReactionFactory]

@DoktorKlawonn

I have more. I was considering trying to save it, but it wasn't worth setting up the distillation apparatus for that much. Also, I'd have to repurify and dry the recovered chloroform before adding it back to the stock.

@ReactionFactory

better extract cocaine from coca leaf then

[jammmon]

and I didnt see any caffeine. You should purify it man.

Put that powder into a glass with a 100 ml water and 10 gr of sodium carbonate. Shake.

The caffeine base should precipitate out of the water, filter or freeze.

Dry it, and wash it with more water, it won't dissolve.

Then smoke it and blow your heart up

[tjiddles25]

do you also have suggestions on further extracion for a more pure sample?

[ReactionFactory]

@tjiddles25

I might try recrystallizing it in a nonpolar solvent like chloroform by dissolving it into the chloroform, filtering out any insoluble components, and then boiling off the chloroform or allowing it to evaporate on its own. There would probably be significant mechanical loss, though, and this would, in all likelihood, only be worth it with a larger quantity of caffeine.

[kuro96inlaila]

You said,

One could either use a tiny amount of tea, and get a pretty reasonable yeild,or a large amount of tea to get a bad yeild.....

May you explain?

[ReactionFactory]

@kuro96inlaila

Using that huge amount of tea meant that I couldn't reasonably get all the liquid tea off the tea leaves. Most of it was still absorbed into the leaves after I decanted the water off. If I had used less, I could have been more careful about extracting all the caffeine off the leaves, and then getting all the liquid tea pressed off the leaves. It was only large relative to my scale of glassware; if I had bigger glassware, I could have done more with the same percent yield.

Nice view off the deck!

[tk0145]

Nothing better than a line of caffeine in the morning!

[hkparker]

Glad to see it went well, yay, another caffeine video!

[jeriellsworth]

I'd love to extract the caffeine out of Jolt cola for those mornings when I need a boost. Good. Thanks for sharing.

[TickyTack23]

@jeriellsworth At that rate, you may as well just buy caffeine pills.

[jeriellsworth]

@TickyTack23 Yes, but that takes all of the science fun out of it.

[coolliger]

great video

[Serostern]

No sound? :(

[yellowmetalcyborg]

Nice video!
