Extraction of eugenol, a natural product, and the preparation of eugenol benzoate

Abstract

This experiment was carried out to extract the eugenol from cloves in the part A, also to prepare the eugenol benzoate in part B. The experiment conducted, extraction of the essential oil eugenol from cloves. To perform this experiment cloves and water were mixed together and heated by a heating mantle in a round-bottom flask. A direct stem distillation took place, and the oil product was out aside for two weeks. After two weeks, the extraction of the eugenol and the preparation of eugenol benzoate actually took place. Next the light yellow eugenol from part A was characterized by the thin-layer chromatography (TLC) plate and 1H NMR analysis; however, eugenol benzoate from part B also was characterized by 1H NMR and Melting Point analysis. The products were analysed to check the purity, and to make sure there are no impurities. The experiment involved the use of techniques, such as steam distillation, gravity filtration, vacuum filtration to collect the product, recrystallization to purify the product, and the weigh to weight out the products.
