I currently have no btc to give, But at least ill put your name in my sig  ::)

I wanted to know how to extract Caffeine from tea.

I know how to extract piperene from black pepper

Also what other plants/herbs can I extract chemicals from and what chemicals are they

Thanks!

better buy decaffeinated tea?

No im trying to extract caffeine just for fun and to have it

Move to Off-Topic maybe?

I put it here because it kinda is a service :P

I think you'll find that its normally done using liquified carbon dioxide as a solvent, under pressure.

I think they usually neutralize the caffeine and turn it into some other substance rather than actually removing it. If you really want caffeine, you can buy powder online, or get some NoDoz (which is mostly corn starch and sugar, but contains caffeine). There is a way to extract the caffeine from NoDoz, however: http://www.instructables.com/id/Extracting-almost-pure-Caffeine-from-Caffeine-Pi/ (http://www.instructables.com/id/Extracting-almost-pure-Caffeine-from-Caffeine-Pi/)

The service to request a service not related to Bitcoin.
Good Try

This is a standard lab for 1st semester organic chemistry.  Go to your local college and buy a copy of "Pavia."

An ordinary teabag will yield between 0 and 10 mg of caffeine, depending on your skill.  I think the Pavia book uses dichloromethane in one of the steps, and this should be changed to a greener solvent.

I suspect it would be just as easy in a home environment to put the tea into an evacuated home canning jar, and deposit the caffein on the lid using dry ice to cool the lid.  I have not, however, attempted this.

where do i get dichloromethane?

This should be changed to a greener solvent.

So what do you recommend professor :)

Take tea leaves, place in hot water, wait a couple of minutes, remove tea leaves. You know have hot water full of caffeine.

But you want to put baking soda into the extract to get all of the caffeine out.  The tea will not taste good, but the goal is to get the caffeine, not drink the tea.

caffine pills? cocaine?

Just like developing your own film is more expensive than taking it to the photoshop, extracting your own caffeine is more expensive than just buying it.  When I have 30 students do this extraction, it probably takes $100 in consumables, and $500 or more in lab space, plus 150 hours of (their) labor.  The total yield for the entire class is probably only 300 mg.

If I count their labor at $8/hr, the cost per gram would come out to be about $6,000 / gram.  I am pretty sure you could get paid to remove bucket fulls of it from any commercial coffee producer.

So all I do is get the tea boil it for a few mins put baking soda and dry? thats it?

Im giving you .05 BTC Whats your address

No.  There will be lots of tannins, the brown colors.  There will be much more of them than caffeine.  Google has some of the Pavia book, but a couple of pages are missing.  Any nearby college library should have a copy of this book.

IIRC erowid has a bunch of strategies for extracting alkaloids.

 I am not much of a chemist :)

Too many chemicals :( Im trying to do it with simple chems like alcohol ect

The secret is, chemists who know what they are doing focus a lot of expertise and effort to do it as simply as it can be done, and still work.
If you try to do it simpler than a consultant tells you to, something will go very wrong.

But can you give me the instructions on what to do please? In a greener way like you said baking soda?

Yeah, at this point the question is really what's your intention with that extraction. Because really you'd have to go ahead and get rid of tannin and other polyphenols and all that other phytopharmaceutical gunk in there to arrive at a few mgs of reasonably "pure" levels of caffeine for hours of work.

At the same time you can just go get yourself a kilogram bucket of pharmaceutical grade pure caffeine synthesized from urea for 40 bucks on ebay.

IT doesnt need to be pure :)

so no instructions

Well this aint exactly a chemistry oriented forum. If you ask about welding, cutting plastic and wood, making them into one, using zipties :P - this is the place
