Isolating caffeine
« on: May 31, 2008, 06:45:25 AM »
Any suggestions on how to isolate caffeine with ordinary household products?  ;)

It doesn't need to be non-poisonous products. This is just for curiosity.

I was thinking of making an warm-extract of instant coffe with ethanol. Than evaporate it and sublimate it on a cold surface... But Im not sure.

Caffeine could also be effectively extracted by supercritical CO2. See below: http://en.wikipedia.org/wiki/Supercritical_carbon_dioxide
For this purpose you need container which could resist pressure of 73 atm...May be not very useful home method though :)
