Separation of the Components of Vodka using Fractional Distillation Fractional distillation‚ also known as rectification or fractionation‚ is common in industrial usage‚ not only for simple mixtures of two components (such as alcohol and water in fermentation products‚ or oxygen and nitrogen in liquid air) but also for highly complex mixtures such as those found in coal tar and petroleum. The purpose of fractional distillation is to separate a mixture of two miscible liquids (liquids that mix

EXPERIMENT 7 - Distillation – Separation of a Mixture Purpose: a) To purify a compound by separating it from a non-volatile or less-volatile material. b) To separate a mixture of two miscible liquids (liquids that mix in all proportions) with different boiling points. Equipment / Materials: large test tubes(3) clamp (1 or 2) ringstand boiling chips test tube rack (1) heating mantle glass adaptor thermometer adaptor 10-mL graduated cylinder condenser (1 or 2) grease 50- mL round bottom flask 50-

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

Name of the Experiment: Simple Distillation (Semimicroscale Procedure.) Abstract: Distillation is a method of process of separating 1:1 mixture based on differences in their volatilities in a boiling liquid mixture. Distillation is done with the use of simple distillation apparatus shown in Figure 1. In this experiment‚ simple distillation process was used to determine the identities of the unknown compounds in the solution through the obtained boiling points. The list of probable unknown volatile

Substitution: The Nitration of Toluene Abstract This industrially important reaction of EAS: The Nitration of Toluene exhibits how the attack of a nitronium ion would give out major and minor products at different positions of toluene. This is an electrophilic substitution mechanism. Mixture of concentrated sulphuric and nitric acid will produce a nitronium ion‚ which will attack ortho-‚ meta- and para- positions at Toluene. (Mechanism at appendix). Introduction/Procedure Toluene is cooled down to almost

Assistant: Lauren February 7‚ 2015 Abstract: The purpose of this experiment is to determine the molar mass of an unknown solid. The freezing point of a solvent (Cyclohexane) was determined‚ and compare to the freezing point of Cyclohexane with the addition of two different concentration of unknown solid. The pure substance of Cyclohexane has defined physical properties. However‚ when a solute is added these properties are determined by the amount of solute added‚ also known as colligative properties

ranged from about 77 degrees in fraction 1 to about 89 degrees in the fraction 10. Next‚ the toluene stayed relatively the same temperature throughout the first 6 fractions at around 69 degrees and then drastically shot up to 100 degrees by the end of fraction 10. This is due to hexane having a lower boiling point and being able to steadily increase through each fraction evenly as temperature rises while the toluene‚ because of its higher boiling component‚ needed the higher temperature in order for higher

Finally tested was the reaction between bromine and alkenes‚ which showed reaction between the more polar alkenes than non polar. Introduction

Distillations are use to purify contaminates out of water to obtain clean pure water‚ as well as‚ to separate mixtures of liquids into their individual components; e.g. methanol and water. Objective: Distill methanol from water using a simple distillation apparatus and fractional distillation apparatus to determine which

Cyclohexane is a saturated hydrocarbon and cyclohexene is an unsaturated hydrocarbon due to the presence of double bond.Both hydrocarbons produce carbon dioxide and water during combustion test. When the oxygen is limited‚ the product will be carbon monoxide and water. The alkenes are highly flammable and burn readily in air‚ forming carbon dioxide and water. In this experiment‚ the combustion of cyclohexene burns in an orange flame and produces relatively high amount of black soot. The black soot
