Distillation Alcoholic distillation is basically the process of separation the more volatile component‚ alcohol‚ from the less volatile component‚ water‚ from a water/alcohol solution‚ by heating the solution and condensing and collecting the alcohol rich vapours released‚ as a high alcohol strength liquid (spirit). The starting material for most distillations‚ such as wine for brandy and beer for whisky‚ are usually weak alcoholic solutions (5%-7% v/v ethanol) This seems counter intuitive

The Fermentation and Distillation of Alcohol By Bhanupriya Chettiar 301 Group Members: Bhanupriya Chettiar‚ Rachel Min‚ Zoe Chandler‚ Bianca Main Aim The aim of the practical is to prepare ethanol by fermentation and to isolate it by fractional distillation. Introduction This practical’s aim is to prepare ethanol using two steps; fermentation and then fractional distillation. Many alcoholic drinks for example‚ brandy and whisky‚ are prepared using this method but to a larger scale. The first

Experiment 2: Dehydration of an Alcohol: Distillation and Gas Chromatography Preparation of Methylcyclohexenes Purpose: The basic purpose of this experiment is to carry out the dehydration of an alcohol and isolate the reaction products by distillation. Gas Chromatography will be utilized to analyze the reaction mixture. Table of Reagents: Compound (g) Molecular Weight (g/mol) Grams (g) Moles 6 mL of 2-methylcyclohexanol (C7H14O) 114.19 g/mol 6 mL x 0.943g = 5.66 g 1 mL 5.66 g x

Experiment D: Separation of Alcohols by Fractional Distillation Pre-lab Properties: Propanol‚ butanol‚ methanol Purpose: To separate two alcohols by distillation and analyze results with GC. Do not plug mantle directly into electrical outlet‚ use controller! Use 40/60 mol percent propanol/butanol (no cyclohexane or toluene are used in this lab because they are more toxic) Set up fractional distillation Set heat at highest level to start‚ then turn back down to 60-80% when vapor starts up column

Abstract In the following project we are discussing about distillation. The operation of the distillation is employed for the purification of liquids from non-volatile impurities. The liquid is heated to the vapor phase and then is collected and recondensed to give back the pure liquid .The non-volatile impurities are left behind in the flask. Here our main focus will be at the fractional distillation. It is the process in which we separate the different components of a mixture on the basis of the

DISTILLATION HISTORY • Distilling was used as early as 3500 BC in Mesopotamia where perfume makers had developed it as a technique for isolating the scented oils of flowers and plants‚ what we know as “attar”. • Around 1100 AD wine was first distilled to make spirit by Irish monks who travelled around Europe. • The results of distillation were considered to have magical powers and this led to alcohol being called “water of life” or “usige beatha” in Gaelic‚ “eau de vie” in French

1 ABSTRACT Distillation is a process by which one liquid can be separated from another liquid‚ or a liquid from a nonvolatile solid. In this experiment‚ the distillations of cyclohexane and toluene mixture were carried out. The purpose of this experiment is to compare the efficiency of simple distillation versus fractional distillation for separation of a mixture of toluene and cyclohexane. The mixture was first separated using simple distillation. A simple distillation apparatus was set

Steam Distillation 6.6.12 Aim: To isolate and extract citrol from lemongrass oil using steam distillation. Theory: Impure chemicals are usually purified using distillation‚ allowing the changes in boiling points to separate the substances. Chemicals with high boiling points decompose before reaching the temperature necessary for separation‚ leading to the invention of steam distillation. The contamination is separated at lower temperatures and allows the separation of chemicals from their
