RESULTS:

Amount of cloves used: 10.0 g
Volume of clove oil obtained: 20.0 mL
Amount of Eugenol obtained: 1.0 g
Percent Recovery of Eugenol: 10%

Observed refractive index of Clove Oil: 1,5320 at 25 deg C
Corrected refractive index of Clove Oil: 1,534

Observed refractive index of Eugenol Acetate: 1,5221 at 25 deg C
Corrected refractive index of Eugenol Acetate: 1,5244

Observed refractive index of Eugenol: 1,5055 at 25 deg C

Corrected refractive index of Eugenol: 1,5078

-------------------------

1. How does your amount of oil recovered in your cloves compare to the expected amount of oil
content in cloves as cited in literature sources?

2. Comment on the purity of the Eugenol that you obtained.

3. Why is the refractive index of clove oil not something that you can find in a CRC handbook?

4. You removed the diethyl ether from the Eugenol by means of a simple distillation. What are two
other methods by which the solvent could be removed?
