Caffiene from Coca Cola –Lab for Organic Chem-

• Objective: Learn a separation method• Extraction: “one of the most common

methods of separating an organic product from a reaction mixture, or a natural product from a plant.”

• We will be examining liquid-liquid extraction, attempting to separate caffeine from soft-drink syrup.

Caffiene from Coca Cola –Lab for Organic Chem-

• To separate an organic product from water insoluble impurities

• Remember: water + moderately polar/nonpolar solvents are the most common in extraction

• Organic product preferentially drawn into the organic solvent in which it is more soluble

• Other components drawn into or remain in water• Organic component “freed” from water soluble

impurities
