Unformatted text preview: Preparation of Eugenol Benzoate 1 Eugenol (4-allyl-2-methoxyphenol) can be easily isolated from cloves. 2 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of an organic molecule by characterizing a solid derivative has been widely used in the past, but has been superceded by modern spectroscopy ( i.e. nuclear magnetic resonance, infrared spectroscopy, mass spectrometry, etc.) OH Cl O OCH 3 KOH, H 2 O O OCH 3 O eugenol benzoyl chloride eugenol benzoate mp 70 o C 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. It is very important that you develop the skills needed to complete ...
