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

Nate Rhodes The Synthesis of Alkenes: Dehydration of Cyclohexanol Organic Chemistry Lab 1 Tuesday 8:00 11/08/11 Paul Jackson Abstract: The goal of this experiment was to form cyclohexene from cyclohexanol through a dehydration reaction. Cyclohexene was successfully synthesized according to the bromine test performed and the IR spectra. There was a percent yield of cyclohexene of 76.1%. Introduction: Alkenes‚ hydrocarbons containing at least one carbon-carbon double bond‚ are important

Synthesis of Cyclohexanol Author: Ahmed Ayyash 06/06/13 Introduction: In this experiment‚ cyclohexanol was prepared from an initial cyclohexene. However‚ this occurred over a number of steps‚ these are out lined below. 1. Cyclohexene + aqueous acid cyclohexyl cation 2. cyclohexyl cation + hydrogen sulphate + water protonated cyclohexanol + cyclohexyl hydrogen sulphate 3. cyclohexyl hydrogen sulphate protonated cyclohexanol + HSO4 4. protonated cyclohexanol + HSO4 ⇄

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

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

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

Alkene Synthesis from Alcohol: Preparation of Cyclohexene From Cyclohexanol 5/29/14 Abstract: A 42.89% yield cyclohexene was successfully synthesized from 10.0 mL cyclohexanol by unimolecular elimination (E1) through the dehydration of cyclohexanol and confirmed via a bromine test and the IR spectra. Introduction: Alkenes are hydrocarbons that have carbon–carbon double bonds and are one of the many functional groups in organic molecules. Alkenes are sp2 hybridized

Title: Preparation of Cyclohexene from Cyclohexanol Aim: To prepare an alkene‚ cyclohexene‚ by the dehydration of an alcohol‚ cyclohexanol‚ and better understand the processes that take place during this reaction. Introduction: One of the common ways of preparing an alkene is through the dehydration of an alcohol. In this experiment cyclohexanol is dehydrated to prepare cyclohexene while using sulfuric acid as a catalyst. A bromine test can be later done to ensure that the end product is

Belden Avenue‚ Chicago‚ IL 60614 smstuckey@comcast.net May 8th‚ 2013 Abstract The first three labs of this organic chemistry experiment involved carrying out the first three parts of the Cyclohexanol Cycle. The cyclohexanol was first converted to cyclohexene and water by simple distillation (product: 6.5395g‚ 79.75% recovery). The cyclohexene then underwent a bromination
