In the experiment of distillation we separated two miscible liquids. The purpose of distillation is to identify and purify compounds. We began our experiment by setting up an apparatus for macroscale simple distillation. We used 60 ml of Cyclohexane/ Toluene. We began with the temperature at 50 degrees Celsius. Unfortunately‚ we reached an error when the compounds evaporated too rapidly. The compounds evaporated so quickly that we lost data from 2 ml to 13 ml. The heat was lowered and as a result

Distilling a Mixture of Cyclohexane and Toluene Lab partner: Chemistry 211 2/08/12 Goal: The purpose of doing this experiment is to separate a sample of cyclohexane and toluene using simple miniscale distillation. The objectives will be to record boiling range and volumes (mL) of distillates that are acquired during the distillation process. It is expected that cyclohexane boils and distils before toluene. By gathering these measurements will allow us to determine refractive index

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

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

room temperature but soluble if heated. Also tested was the reactivity of cyclohexane and cyclohexene in sulfuric acid which tested to prove reactivity between cyclohexene but not cyclohexane. Finally tested was the reaction between bromine and alkenes‚ which showed reaction between the more polar alkenes than non polar. Introduction

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

Toluene is a clear colorless liquid that has an aromatic odor. It ignites in air at 40 degrees Fahrenheit. It is also less dense than water and because so will float atop it. Toluene is non-corrosive. Toluene is in a ton of things! Toluene is used in aviation gasoline‚ high-octane blending stock‚ and petroleum/coal production. It is used as a solvent in things we use everyday like paints‚ coatings‚ and gums. Toluene occurs naturally in crude oil and in the tolu tree. The tolu tree is where Toluene

We reached our goals through our experimentation. We tested the solubility of each of the starting and ending materials in water‚ HCl‚ NaOH‚ toluene‚ and acetone. We discovered that the starting materials would only dissolve in toluene. To make the soap‚ we obtained about 10 mL of vegetable oil and 10 g of lard and we placed them both in separate 250 mL beakers. While we were stirring the compounds‚ we also added 15 mL of 6 M NaOH drop by drop and 1 mL of glycerol. We then heated our solutions
