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

The Synthesis of Alkenes: The Dehydration of Cyclohexanol Adam Ohnmacht CHEM 0330 Scott Caplan 10/30/12 Abstract: In Organic Chemistry‚ many different methods are used to synthesize organic compounds from various components. In this lab‚ cyclohexanol was dehydrated to cyclohexene through an elimination reaction. In order to separate the cyclohexene product from the cyclohexanol starting component‚ previously learned lab techniques such as extractions and simple distillation were used.

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

The Effectiveness of Phosphoric Acid on Meat Chapter I. Introduction A. Background Of The Study This experiment was performed to find out if the acidity in Coca Cola could dissolve meat. The testing was done by placing pieces of pork‚ chicken breast and salmon into bowls filled with Coca Cola‚ and observing meat for 5 days. Coca Cola is a popular carbonated beverage that is sold in more than 200 countries. Also known as Coke‚ it can be purchased from vending machines‚ department stores and

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

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 In 1994‚ thousands of starving people died in the Africa nation of Rwanda. It wasn’t lack of food that killed most of these people‚ but cholera‚ a bacterial infected that cripples the ability of intestinal mucosal cells to reabsorb water. The severe diarrhea that develops can kill in days‚ sometimes even hours. Dehydration is deadly. Dehydration is a deficiency condition that occurs when output of water exceeds intake. It is a great problem for athletes‚ military personnel‚ and certain
