Isolation of caffeine flowchart

To isolate caffeine, start by brewing coffee or tea to extract the caffeine into a liquid solution. Next, use a separation technique such as liquid-liquid extraction, adding a non-polar solvent to separate caffeine from water-soluble compounds. Afterward, evaporate the solvent to obtain crude caffeine, and finally, recrystallize it from a suitable solvent (like ethanol) to purify the caffeine further. This flowchart outlines the steps of extraction, separation, evaporation, and purification.
