Isolation of Eugenol from Cloves by Steam Distillation and its Identification by Infrared Spectroscopy Eim A. Chemist CHEM 303 June 16‚ 2005 INTRODUCTION “Essential oils” are the volatile components associated with the aromas of many plants.1 In this experiment‚ the essential oil eugenol (the main component of oil of cloves) will be isolated from ground cloves using the technique of steam distillation‚ which is often used to isolate liquid natural products from plants.2 The principle

extraction of a natural product using the techniques of steam distillation. The principle component of oil of cloves is an aromatic compound‚ which is identified by thin layer chromatography (TLC). Eugenol is widely used in dentistry‚ due to its analgesic‚ antiseptic balsamic qualities. It is ideal for curative for pulp hyperemia (the soft‚ sensitive substance underneath the enamel and dentine of a tooth) and pulp its. In dentistry eugenol is also used to cover cavities‚ fill canals‚ etc. It also

Isolation of Eugenol from Cloves Abstract The experiment conducted‚ isolation of eugenol from cloves‚ is the extraction of the essential oil. 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 a week. After one week‚ the isolation of the eugenol actually takes place. Next the thin-layer chromatographic analysis takes place‚ but the experiment

Cross* Summary The isolation of Eugenol from Cloves begins with whole cloves and then using a steam distillation apparatus to obtain the cloves oil substance. Then with the mixtures of water and dichloromethane to form two immiscible layers. The layers were dichloromethane substance and aqueous The entire substances that are separated into two individual

In this experiment‚ the essential oil eugenol was isolated from ground cloves using steam distillation techniques. Eugenol had a high boiling point‚ but it was isolated at a lower temperature by performing a co-distillation with water‚ a process known as steam distillation. This technique allowed the desired material to be distilled at a lower temperature than 100℃. The point of the steam distillation was to use an azeotrope to isolate the organic compound from a solid. The azeotrope was the liquid

Steam distillation of cloves produced 0.53g of an oil which contained in its IR spectrum the functional groups O-H (at 3520 cm-1)‚ sp2 C-H (3080 – 3000 cm-1)‚ aliphatic C-H (2980 – 2940 cm-1)‚ and both alkene C=C (at 1640 cm-1) and aromatic C=C (at 1514 cm-1). The IR spectrum is attached to this report. These data are consistent with the structure of eugenol‚ shown in Figure 2 below: In addition‚ the IR of the product from the steam distillation of cloves closely corresponds with that of an

Isolation & Identification of the Major Constituent of Clove Oil with Steam Distillation The purpose of this laboratory experiment was to isolate and characterize clove oil in order to understand how to isolate organic compounds with high boiling points‚ how to perform and interpret qualitative tests for organic compound functionality‚ and to continue to learn how to perform and interpret IR spectrometry. Steam distillation was used in order to prevent the organic compound from decomposing

Steam Distillation – Clove Oil Abstract: In this experiment‚ a situ method steam distillation was performed and essential oils were isolated from cloves. Once the oils were obtained‚ extraction techniques were used to extract a crude‚ eugenol‚ and acetyleugenol product sample. These samples were submitted for GC analysis and the normalization area percents were calculated to confirm their purity; for the crude sample it was 93.95% eugenol and 6.05% acetyleugenol‚ for the eugenol sample it

Cheryl Baclit Chem 234 Experiment 4: Steam Distillation Introduction The purpose of this experiment is to extract Eugenol from Cloves using steam distillation as a purification technique and to transfer Eugenol from the aqueous phase to the MeCl2 phase. With steam distillation‚ the boiling point of a mixture of immiscible liquids is lower than the boiling points of the individual components. Water from the steam is one of the components of an immiscible liquid mixture. The vapor pressures of

Introduction In this experiment‚ the essential oil eugenol (the main component of oil of cloves) will be isolated from whole cloves using the technique of simple distillation‚ which is often used to isolate liquid natural products from plants. The mixture of whole cloves and distilled water will then be heated to boiling and the distillate (a eugenol/water mixture) will be collected. The eugenol will then be separated from the water by extraction with pentane. The pentane solutions will then be
