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 was 100%

Experiment 7- Isolation of the Major Component of Clove Oil Pre-Lab Questions: 1.) Briefly explain the concept of steam distillation. What is the difference between a simple distillation and a steam distillation? When a mixture of two immiscible liquids are distilled it is referred to as codistillation. This process is referred to as steam distillation when one of the liquids is water. This distillation is used to separate organic liquids from natural products and reaction mixtures in which

Constituents of Clove Oil Organic Chemistry Laboratory II‚ 10 February 2011 Corey Cates Introduction and Objectives The purpose of this lab was to obtain a pure sample of clove oil from ground cloves using steam distillation‚ perform infrared spectroscopy on the sample‚ and analyze the IR to identify the major constituent in the clove oil. The first day the clove oil was removed from the ground cloves into an aqueous solution then removed from the water using DCM. The sample was left in a sealed

Introduction In order to understand what HPLC‚ that is‚ High Performance Chromatography‚ it is necessary to understand the meaning of the term chromatography itself. Chromatography Chromatography is defined as a procedure by which inert materials and drug principles encountered in pharmaceuticals preparations are separated by fractional extraction‚ adsorption‚ or ion exchange on a porous solid. Chromatography is particularly useful as a means of separating and purifying complex and closely

Extraction of Eugenol from Cloves 02/01/2014 CHM2210L University of North Florida Abstract Eugenol is found in the essential oil of cloves and has distinct properties that make it an important product to both food and drug industries. (Bhimrao‚ et. al‚ 2004). To utilize many of eugenol’s characteristic properties‚ it is necessary to isolate this organic chemical from the other components of cloves. In this experiment‚ eugenol was isolated from a sample of cloves using a series of techniques

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

high-pressure liquid chromatography)‚ HPLC‚ is a chromatographic technique used to separate the components in a mixture‚ to identify each component‚ and to quantify each component. HPLC is considered an instrumental technique of analytical chemistry (as opposed to a gravimetric technique). In general‚ the method involves a liquid sample being passed over a solid adsorbent material packed into a column using a flow of liquid solvent. Each analyte in the sample interacts slightly differently with the

METHODS OF FOOD PREPARATION Because guests often ask how food on the menu is prepared‚ you should know the more common preparation methods‚ as follows: • Baked Cooked by dry‚ continuous heat in an oven • Boiled Cooked in liquid at the boiling temperature of 100°C ( 212°F) at sea level‚ so that bubbles rise to the surface and break • Braised Browned in a small amount of fat and then cooked slowly in a little liquid in a covered pan • Broiled Cooked by direct heat‚ either under the source of heat‚
