How do I extract caffeine from ground coffee beans?
Answers:
are you trying to get decaf coffee or pure caffeine? if you want decaf coffee, you might be able to use the swiss water method. this is where you soak the beans in hot water, extracting the flavor and caffeine, then you dump the beans and add new ones to the water and keep repeating the cycle until the water is saturated with flavor. when that happens, the water won't absorb any more coffee solids, only caffeine. whatever's left is your decaf coffee beans. of course, you'd have to throw out several batches of regular coffee to get one batch of decaf, and since you already ground the beans, you'll be left with wet grounds that you'd have to dry. it'll be disgusting.
if you're trying to get pure caffeine, you'd need either activated charcoal or supercritical carbon dioxide. whatever you're trying to do, it'll be more expensive than simply buying new beans, or buying an otc caffeine pill.
