Estimation of the Activation Energy for the Iodination of Acetone Through the Effect of Temperature on the Rate Constant Joel Costa‚ Alex Fuentes‚ Michael Chea‚ Rex Nwerem Dr. Morgan Ferguson July 9‚ 2013 ABSTRACT | It is often important to determine the rate at which a chemical reaction takes place‚ i.e.‚ how fast it yields the desired products. Temperature is one of the factors that influence the rate of reactions and it does so by providing energy to reactant particles so that a larger

Rates of Reaction: Iodination of Acetone Introduction: The rate at which a chemical reaction occurs depends on several factors: the nature of the reaction‚ the concentrations of the reactants‚ the temperature‚ and the presence of possible catalysts. In this experiment you will study the kinetics of the reaction between iodine and acetone in acid solution: For this reaction‚ you will determine the order of the reaction with respect to acetone and HCl and find a value for the rate constant‚ k.

Lab Report Iodination of Acetone Temperature as a Variable Objective The objective of this lab is to determine the energy of activation of the iodination of acetone. This will be done by performing the reaction at differing temperatures. The same reaction orders we obtained for the previous lab will be incorporated into this experiment. The equation Ea = -8.31 x slope of ln k vs. 1/T(K) will be used to determine the energy of activation required for this this reaction. Hypothesis

Experiment A1: Kinetics of the Reaction between Acetone and Iodine The key aim of this experiment was to determine the rate equation for the acid-catalysed iodination of acetone and to hence consider the insinuations of the mechanism of the rate equation obtained. The stoichiometric equation for the reaction between iodine and acetone is below‚ followed by the rate equation (where x‚y‚z and k are the values to be obtained): I2 + CH3COCH3 CH3COCH2I + HI -d[I2]/dt = k [I2]x [CH3COCH3]y [H+]z

CHAPTER 1 PRODUCTION 236250 TONNES PER YEAR OF ACETONE 1.0 INTRODUCTION Acetone is a clear‚ colorless‚ volatile liquid with sweer odor. It is both the simples aliphatic ketone and the most commercially important. It has a distinctive fruity or mint-like odor and a pungent taste. It is also found naturally in plants‚ tress‚ volcanic gases‚ and forest fires and as a by product of the breakdown of body fat. Nearly all world production of acetone is via cumene peroxidation‚ as a coproduct with phenol

INTRODUCTION Acetone also called 2-propanone or dimelthyl ketone is the organic compound with the formula of (CH3)2CO. Acetone is one of the simplest of the organic compound that called ketones. The figure below showed the chemical structure of acetone: Figure 1: Chemical structure of Acetone This chemical is the one of the most important in chemical industry due to their properties. It is a colorless liquid that has a characteristic of sweet odor and used as a nail polish remover. It

The Iodination of Salicylamide Questions: 1. a) The possible sites of iodination of the salicylamide ring is on the ortho/para position to the -OH group. b) The most likely site of iodination is the para position. This spot has the least steric hindrance and is favorable due to the directing effects of the -OH and the withdrawing effects from the carbonyl. 2. The homo surface shows that salicylamide has large electron density at the para and ortho positions. These sites are more likely

5.1 MANUFACTURING PROCESSES: Acetone is produced directly or indirectly by propylene. Early processes for the manufacture of acetone were based on the thermal decomposition of calcium acetate or the carbohydrate fermentation of corn starch or molasses. The ready availability of propylene in the 1960s led to routes based on the dehydrogenation of isopropyl alcohol or cumene peroxidation. (1) By Cumene Oxidation (Hock Process). Propene is added to benzene [71-43-2] to form cumene [98-82-8]‚ which
