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

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.
