https://tube.loping.net/videos/watch/e68dc4a6-3ee6-4c7a-b50a-68c071823a38 I tried to extract caffeine from green coffee beans using supercritical CO2, but I had no success. The beans underwent a strange transformation, becoming white and rubbery after 6 hours at 80*C in supercritical CO2. I also used water and ethanol as a cosolvent, thinking that the caffeine would end up in solution in the water/ethanol mix after the CO2 became subcritical. Do you have any advice about how this process is supposed to work?
