YOUR NAME: Erin Alston‚ Kennedy Stuart‚ Amber Lamb and Stephonya Williams EXPERIMENT TITLE: Oxidation: Cyclohexanone from Cyclohexanol by Hypochlorite Oxidation and Adipic Acid from Cyclohexanone DATE: 4/18/2014 INTRODUCTION: In experiment 4‚ alcohol is oxidized to a ketone with household bleach. The product is then isolated by steam distillation and is extracted into the distillate with ether. After the removal of ether‚ it leaves the product cyclohexanone. In experiment 6‚ cyclohexanone is

naked eye. It was concluded that 5 of the combinations proved soluble‚ 2 completely insoluble‚ and 2 were insoluble at 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

Francesca; Lañez‚ Kristine Department of Psychology College of Science University of Santo Tomas España Manila 1015 Abstract A hydrocarbon is strictly composed of carbon and hydrogen atoms only. Five hydrocarbons were used namely hexane‚ cyclohexene‚ toluene‚ naphthalene (in hexane)‚ and the unknown (which will be known through parallel chemical tests). Three tests‚ nitration test‚ bromine test and basic oxidation test were conducted to fully differentiate each type of hydrocarbon from one

recyclable catalyst will be examined. This article will discuss how manipulating equivalents of 30% hydrogen peroxide (H2O2) affect the product yield. Results show product yield was affected when changing H2O2 equivalents. Equivalent ratio 1:4 (cyclohexene to H2O2) was most ideal‚ with an average yield of 27.37%. Understanding ideal greener approaches may help mediate the negative environmental impact. _______________________________________________________________ Adipic acid (ADA) is used in

Procedure: Oxone reaction Dissolve 0.40 g oxone ® in 2.0 mL of water by shaking vigorously in a sealed vial. (Caution! Be sure the vial is sealed because oxone is a strong oxidizer.) Dissolve 50 L of cyclohexene in 2.0 mL of acetone in a small Erlenmeyer flask. Cool the cyclohexene solution in an icebath‚ then add the oxone solution dropwise over 5 minutes with swirling in the icebath. Remove the Erlenmeyer flask from the icebath and allow the reaction to sit for 15-30 minutes. (To save

OXIDATION OF CYCLOHEXANOL TO CYCLOHEXANONE The oxidation of cyclohexanol to cyclohexanone involves the removal of hydrogen from the OH group. After separation and purification‚ an Infrared Spectrum will be run to determine the composition of the recovered material. Infrared Spectroscopy is a very powerful technique used in the determination of molecular structure and the identification of unknown organic materials. The infrared spectrum yields direct
