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 of steam distillation is based

An Experiment to investigate how the Initial Height of which a Ball is dropped affects its Fractional Loss of Kinetic Energy Research Question: What is the relationship between initial height of a drop and the fractional loss of kinetic energy in a bouncing ball? Introduction: When an object is held at a height above the ground‚ it possesses gravitational potential energy (Ep = mg∆h) that is directly dependent of the mass and height of which the object is positioned above the ground.

The Distillation of an Unknown Compound INTRODUCTION Distillation is the process heating a liquid to form vapor which is then collected when cooled and separated from the original liquid. The purpose of this experiment was to determine the identity of an unknown substance using simple and fractional distillation. Gas chromatography analysis the components of a mixture by separation of the materials by their different boiling points. EXPERIMENTAL The simple distillation apparatus was assembled

qualitative analytical chemistry. The group will be given an unknown pure organic liquid sample and will need to perform a series of tests in order to identify the species in question. The tests being: determining the boiling point using two methods (distillation and capillary tube)‚ determining the refractive index‚ and obtaining UV/VIS and FT-IR absorption spectra. After the results from the various tests are obtained‚ the boiling point and refractive index should be compared to literature data while

A number of other methods can be used to synthesize the ester group. Among these are the addition of 2methylpropene to an acid to form t-butyl esters‚ the addition of ketene to make acetates‚ and the reaction

Process Description Acetaldehyde is produced via dehydrogenation of Ethanol. The reaction is as below: CH3CH2OH CH3CHO + H2 ‚ ΔH = +82.5 kJ/mol Besides the main reaction producing Acetaldehyde‚ there are three side reactions present in the reactor‚ as shown below: 2 CH3CH2OH CH3COOC2H5 + H2 2 CH3CH2OH CH3(CH2)3OH + H2O CH3CH2OH + H2O CH3COOH + H2O The feed of 90% Ethanol is kept in a storage tank with an air vent.

and characterization of isoamyl acetate‚ or banana oil‚ was determined. The synthesis was completed by a reversible esterification reaction which required the heating of glacial acetic acid and isoamyl alcohol‚ combined with a sulfuric acid catalyst in hexane. In order to increase the efficiency of the reaction‚ LeChatelier’s Principle is utilized by removing water from the products. As a result‚ the reaction as a whole shifts the left producing more isoamyl acetate to try and balance the reaction
