Questions & Answers

Q: Why is cinnamaldehyde extracted from cinnamon sticks?

Cinnamaldehyde is extracted from cinnamon sticks because it is responsible for cinnamon's distinct flavor and smell.

Q: What is the purpose of steam distillation in this experiment?

Steam distillation is used to extract cinnamaldehyde from cinnamon sticks by vaporizing the cinnamaldehyde and condensing it into a distillate.

Q: How can you determine the concentration of cinnamaldehyde in the distillate?

The level of cloudiness in the distillate provides an indication of the amount of cinnamaldehyde oil present, with a clearer distillate indicating a lower concentration.

Q: How is the cinnamaldehyde oil separated from the distillate?

The distillate is transferred to a separatory funnel, and a washing process using DCM (dichloromethane) is carried out to separate the cinnamaldehyde oil from the aqueous layer.

Summary & Key Takeaways

  • Cinnamaldehyde, found in the bark of cinnamon trees, can be extracted through steam distillation.

  • Crushed cinnamon sticks are added to a round bottom flask with distilled water and heated on a hot plate to start the distillation.

  • The distillate collected contains an insoluble suspension of cinnamaldehyde oil, which appears cloudy, indicating its concentration.
