Introduction: This experiment involves an 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

SEPERATING CYCLOHEXANE AND TOLUENE BY DISTILLATION Aim: Separate two miscible liquids‚ either by macroscale or microscale process‚ using simple and fractional distillation. Compare the efficiencies of simple and fractional distillation. INTRODUCTION: The purpose of this experiment is to learn how to separate two miscible liquids by microscale process. There will be use of simple and fractional distillation. Simple and fractional distillation efficiencies will be compared. The student should have

Distillation is one of the most common separation techniques used in laboratories or industries where liquid chemicals are separated based on their volatilities. Distillation is usually done by vaporizing the liquid mixture in one vessel and condensing the vapors into another. The liquid mixture being distilled is called distilland and the resulting liquid is called distillate. In laboratories‚ there are several types of distillation used according to the needs such as simple distillation which involves

The Knoevenagel Condensation Preparation of Ethyl 3-Coumarincarboxlate Ivy Akatsa Organic Chemistry Introduction Knoevenagel Condensation uses a compound of the type X-CH2-Y as the carbanion source‚ where X and Y are the electron withdrawing groups such as –CN‚-COOR‚-COR‚ NO2‚ etc. These groups are capable of stabilizing an adjacent carbanion by resonance. So in this experiment‚ the Knoevenagel Condensation of diethyl malonate with aromatic aldehyde salicylaldehyde involves an initial

Estimate how much the money supply will increase in response to a new cash deposit of $500 by completing the accompanying table. (Hint: The first row shows that the bank must hold $100 in minimum reserves—20% of the $500 deposit—against this deposit‚ leaving $400 in excess reserves that can be loaned out.

Simple and Fractional Distillation Experiment II Stancy Saji‚ 18 September 2014 Purpose Experiment II involved two kinds of distillation techniques: simple and fractional. Simple distillation was done to separate ethyl acetate—which has a usual boiling point of 77º—from a less volatile component‚ while fractional distillation was done to distinguish an ethyl acetate/n-butyl acetate mixture‚ which has boiling points of 77º and 125 º‚ respectively. Results and Discussion As previously stated the

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 at
