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

Simple Distillation‚ Gas Chromatography: Preparation of Synthetic Banana Oil Introduction This experiment gave us the opportunity to work with a variety of new procedures as well as practice procedures that are new to us within the past few weeks of labs. Within the context of the scenario‚ we find that a distilling company that markets a popular banana liqueur is having problems. The banana plantation that they use to create their banana extract was hit hard by a hurricane and their reserves

Chem 2203 Sec 026 27/September/2013 Experiment 3B: Fractional Semi-microscale Distillation Separation of Hexane and Toluene. Objective: The main goal of this lab is to learn how separation of binary liquid mixtures is performed. Especially when the two liquids have boiling points varying by about 30° C. Hexane can be separated from toluene in this experiment because of the difference in their boiling points. Since toluene has a higher boiling point‚ it will left at the bottom while the hexane

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

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

Fraction (mathematics) A fraction (from Latin: fractus‚ "broken") represents a part of a whole or‚ more generally‚ any number of equal parts. When spoken in everyday English‚ a fraction describes how many parts of a certain size there are‚ for example‚ one-half‚ eight-fifths‚ three-quarters. A common‚ vulgar‚ or simple fraction (examples: \tfrac{1}{2} and 17/3) consists of an integer numerator‚ displayed above a line (or before a slash)‚ and a non-zero integer denominator‚ displayed below (or after)

Organic Chemistry II Lab 9 Fermentation of a Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast

In order to teach students the concept of equivalence when working with fractions with unlike denominators or finding equivalent fractions‚ there are some skills that the students must already possess. These are as follows: Students are able to both recognize and write fractions Students understand the ‘breakdown’ of a fraction where the top is the numerator and the bottom is the denominator Students must have some understanding of equivalence and what it means Students must be able to both

Partial Fractions A way of "breaking apart" fractions with polynomials in them. What are Partial Fractions? We can do this directly: Like this (read Using Rational Expressions to learn more): 2 + 3 = 2·(x+1) + (x-2)·3 x-2 x+1 (x-2)(x+1) Which can then be simplified to: = 2x+2 + 3x-6 = 5x-4 x2+x-2x-2 x2-x-2 ... but how do we go in the opposite direction? That is what we discover here: How to find the "parts" that make the single fraction (the "partial fractions")
