Extracting (almost pure) Caffeine from Caffeine Pills.

Step 5: You're done...

The caffeine can be used for what ever you wish.
It will still have a bitter taste but a lot less than if you had not done this.


This method can be used for many different substance extractions.

There is another way to extract caffeine by heating it until it sublimes and condensing it after it evaporates.

I've done it for acetone peroxide dissolved in acetone (it is not recommended because it is very friction sensitive so you have to keep it slightly "wet" as to not trigger an explosion).

Furthermore, if you re-dissolve the caffeine and repeat the process leaving the undissolved layer on the bottom, you can further purify your caffeine.

Firstly, the above comment people are dippy. :P Use 90% alcohol or everclear, this method is completely safe and highly recommended for any substance you want to extract. Keep alcohol away from flame and wear disposable gloves when handling any extracted substance. Also pyrex baking dishes are used instead of pane of glass to prevent loss of product. As with everything read up on dosages of the substance you are extracting and use a accurate gram/mgram scale.

Alcohol won't extract anything. Also the water in it could hydrolyze lots of things.

This method definately is not safe. If you use pure grain alcohol as a solvent it would be much better. Also if you have a mel-temp melting point apparatus you can test the purity of your caffeine. caffeine melts at 237 degrees Celcius.

Why isn't it safe? The methanol is the only other ingredient in his brand of denatured alcohol.

I wouldn't put this in my mouth even if I were about to fall asleep during my favorite episode of the office. sorry, but if you have to say it's not your fault if I kill myself, I won't do it.
