View lab report - isolation of eugenol from cloves by distillation from chemistry chm2010 at broward college christie gomez with lab partner: jean joseph march 29, 2016 chemistry 2211 lab professor. Isolation of eugenol from cloves by distillation purpose: the purpose of the experiment is to use distillation to extract an essential oil, specifically eugenol oil, from a plant, the clove. In addition, the ir of the product from the steam distillation of cloves closely corresponds with that of an authentic sample of eugenol shown in the lab text9 therefore, it can be concluded that the oil which was isolated from cloves is in fact, eugenol.
Isolation of eugenol from cloves by steam distillation and its identification by infrared spectroscopy. Extraction of eugenol from cloves in this experiment, you will extract the essential oil of cloves, which is mostly eugenol the procedure used is typical for isolating products from natural sources introduction herbs, spices, and so-called essential oils were commonly used well before.
If we replaced the steam distillation step with a reflux extraction it would be the percent of eugenol in cloves leaving the solid behind it will be used as the distilling flask spicy odor of cloves and that is about 98% eugenol. Isolation of eugenol from cloves name justin arthur student lab partner witness 1 the apparatus sketched below was assembled and charged with 1032 g of ground cloves and 17 ml distilled water the cloves were soaked for about 15 min until thoroughly wetted 2 the mixture was heated to boiling initial hot plate setting = 3.
Eugenol concentration in clove oil is as high as 90% eugenol is also found in bay leaves and allspice, and other botanical oil, but in lower concentrations essential oils are extracted, depending on the nature of the botanical material, by a variety of techniques, including expression (cold-press), solvent, enfleurage (cold-fat) and supercritical fluid (scf) extraction, and distillation. The boiling point of eugenol, an oil found in cloves, is 248 °c, but it can be isolated at a lower temperature by performing a co-distillation with water, this process is also know as a steam distillation. Extraction of eugenol from cloves (1) - download as pdf file (pdf), text file (txt) or read online.
Isolation of eugenol from cloves by distillation purpose: the purpose of the experiment is to use distillation to extract an essential oil, specifically eugenol oil, from a plant, the clove introduction: essential oils are components of various compounds and are associated with scents and medicinal purposes. Both eugenol and neutral product are separated from water by acid-base extraction the characterization of eugenol and neutral product are performed by using ir spectroscopy and gas chromatography and mass spectroscopy (gc-ms. Eugenol extraction from cloves using steam distillation the goal of this experiment is to isolate the natural product, eugenol, from cloves using the following procedure.
The ir spectrum is attached to this report 00983 g of eugenol was recovered from 101 g of cloves this corresponds to a percent recovery of 983% introduction: the point of this was to learn the techniques of isolation of natural products. Extraction were used to isolate eugenol from cloves steam distillation was used because of the high boiling point of eugenol tlc & nmr were used in order to test the effectiveness of steam distillation steam distillation the boiling point of water is 100ºc and the boiling point of eugenol is 254ºc. Eugenol, c 10 h 12 o 2 is a one of the compound of phenylpropanoid family it is a pale yellow oily compound that extracted from essential oil especially from cloves and bay leaf it is a pale yellow oily compound that extracted from essential oil especially from cloves and bay leaf. Eugenol, the main ingredient in clove oil, is a familiar fragrance in many dental offices as it is often mixed into a paste and used in dentistry as a local antiseptic and anesthetic it is a pale yellow oil with a warm, pungent, yet pleasing aroma, the smell of bay leaves and clove.
