Coffee is decaffeinated industrially using supercritical (sc) CO2. One advantage to using scCO2 is that the polarity of the supercritical fluid can be tuned by varying temperature, pressure and cosolvent additives. However, the need for high temperatures and pressures makes generation of scCO2 impractical in a teaching lab setting. Based on its structure and polarity, would you expect caffeine to be soluble in liquid CO2 (i. e. if we carried out this experiment with tea leaves instead of orange rind, would you expect it to work)? Why/why not?
