Preparation of Eugenol Benzoate
Eugenol (4-allyl-2-methoxyphenol) can be easily isolated from cloves.
In order to aid in the
identification of this natural product, eugenol can be reacted with benzoyl chloride to produce a
solid, eugenol benzoate.
A melting point may be obtained to confirm that the desired product
was produced and therefore, that eugenol was isolated.
This method of indirect
characterization of an organic molecule by characterizing a solid derivative has been widely
used in the past, but has been superceded by modern spectroscopy (
resonance, infrared spectroscopy, mass spectrometry, etc.)
This reaction will be performed on a very small scale for two reasons.
First, in a modern
scientific lab, experiments are often carried out on as small as a few milligrams of starting
material or a microscale.
