Ethyl acetate is the
general replacement in that classic laboratory experiment.
Requires approximately 4x more solvent, however. Google
this: caffeine extraction "ethyl
acetate"
Caffeine from tea or coffee is an
excellent experiment to demonstrate supercritical CO2 extraction, but I
expect the instructor is trying to demonstrate classic two-phase
extractions.

I found out today that one of
our teaching labs is conducted an extraction experiment with
dichloromethane (caffeine from coffee)
I
would like to provide them a reasonable alternative extraction
experiment with an occupationally regulated
carcinogen=85
If you have a recommendation to look at, would you please contact
me?
Thanks,
