Oxidation of Cyclohexanol Introduction: The oxidation of cyclohexanol involves using household bleach to oxidize this secondary alcohol and produce a ketone product‚ cyclohexanone. Oxidation-reduction (redox) reactions occur when the oxidation state of atoms change due to a transfer of electrons. Oxidation occurs when electrons are ‘lost’ to the formation of bonds and reduction occurs when electrons are ‘gained’ in the braking of bonds (Levine). Using this reaction and its product‚ a redox experiment

April Goodson CHEM 242L-002 February 20‚ 2013 Oxidation of Cyclohexanone to Adipic Acid Abstract The cyclic ketone cyclohexanone was oxidized to adipic acid using the oxidizing agent nitric acid. The experiment yielded 0.2667 grams of adipic acid‚ giving a percent yield of 113.97%. Although the product was allowed to dry for one week‚ residual moisture was still present in the sample and a melting point could not be obtained. This error in the experiment either resulted from adding too much

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 oxidized by potassium permanganate. Manganese

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

Introduction: Cyclohexanol is mainly used in the production of caprolactam and adipic acid that is a raw material of nylon 6 (Zhang‚ et al‚ 2002). Cyclohexanol can be produce through several methods‚ which include the oxidation of cyclohexane‚ the hydration of cyclohexene‚ or the hydrogenation of phenol (Zhang‚ et al‚ 2002). Problem with oxidation of cyclohexene is poor selectivity‚ extremely large recycles and explosion hazards. (Suresh‚ Sridhar‚ Potter‚ 1988). The purpose of this experiment was

Dehydrating Cyclohexanol • Introduction The purpose of the lab experiment is to prepare cyclohexene from cyclohexanol through an acid-catalyzed dehydration. In order to produce the cyclohexene from cyclohexanol‚ an elimination reaction was performed. First by protonating the oxygen of the alcohol and creating an oxonium ion we replaced the poor leaving group (OH) into a better leaving group (OH2+). Second‚ dehydrating the cyclohexanol using phosphoric acid and sulfuric acid as acid catalysts

Dehydration of Cyclohexanol Introduction In this experiment cyclohexene‚ an alkene‚ was prepared by the dehydration of cyclohexanol‚ an alcohol‚ using phosphoric acid‚ an acid catalyst. The reaction is as follows: [pic] The dehydration of cyclohexanol was performed in a simple distillation apparatus. As cyclohexene formed‚ it was distilled out of the mixture. Background Dehydration is an elimination reaction of an alcohol that takes place in the presence of an acid catalyst

In the first experiment‚ cyclohexanol was oxidized to form cyclohexanone. This was accomplished by pouring 2.0 ml of cyclohexanol and 1.0 ml of acetic acid into a 250 ml Erlenmeyer flask. Under a fume hood‚ slowly add 30 ml of bleach‚ and oxidizing agent‚ to the mixture and stir for 20 minutes. Acetic acid will react with bleach to make it a better oxidizing agent and form hopochlorous acid. Hypochlorous acid will then oxidize cyclohexanol. The mixture turned cloudy during the process but clear up
