Lab 10: Isolation of Identification of the major constituent of clove oil
Purpose: The purpose of this lab was to isolate the cove oil from ground cloves and determine the identity of the major constituent that is known to have the molecular formula C10H12O2 through IR spectrometry.
Many people search for alternative ways to treat illnesses other than the conventional use of drugs and surgery. These alternative ways include aromatherapy, naturopathy, and homeopathy. Aromatherapy uses essential oils to treat the illness. Naturopathy is a system of treating diseases through using essential oils to treat the illness. Naturopathy is a system of treating diseases through using a…show more content…
During the separation of a minor component, the addition of HCl to the NaOH layer created the mixture to be a little cloudy but then it became clear again.
Everything went according to plan in this lab. The steam distillation actually went well overall and we had a successful system. Through the analysis of the IR spectrum, it can be seen that the unknown constituent of the major constituent contained a O-H-N-H stretch, Phenol ring and C7H16. Reading peaks was a little iffy, because some peaks were hard to read or interpret. Through using figure 10.1 on page 110, I came to the conclusion that the structure of the major constituent is:
Exercises 1. Derive a systematic name for the active component of clove oil, and use this to find its common name in The Merck Index or another reference book.
Systematic name: (E)-4,11,11-trimethyl-8-methylenebicyclo[7.2.0]undec-4-ene.
Common name: eugenol
6. A. Clove oil also contains a small amount of a substance whose systematic name is (E)-4,11,11-trimethyl-8-methylenebicyclo[7.2.0]undec-4-ene. Write the structure of this compound and find its common name it The Merck Index or another reference book.
7. Following the format in Appendix V, construct a flow diagram for this experiment. If you followed the standard-scale procedure, show how the active component is separated from the solid part of the cloves and the component mentioned in exercise 3.
