S5E1 Gaseous Diffusion 1.0 ABSTRACT In this experiment‚ our objective is to find out the gas diffusion coefficient‚ D of acetone in the air. This experiment is conducted at a temperature of 50ºC and atmospheric pressure. The method that is applied to conduct this experiment is called the Winkleman method where the level of acetone (Z) is determined every 15 minutes by using a microscope. With the level of acetone being determined‚ a graph of t/L+Lo (min /mm) vs. L-Lo (mm) is plotted and the

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

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

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

Balances‚ Numerical Methods Design Project Production of Acetone Process Description Figure I is a preliminary process flow diagram (PFD) for the acetone production process. The raw material is isopropanol. The isopropanol (lPA) feed is a near azeotropic mixture with water at BB wt yo IPA at 25"C and I atm. The feed is heated‚ vaporized‚ and superheated in a heat exchanger (E-401)‚ and it is then sent to the reactor (R-401) in which acetone is formed. The reaction that occlrrs is shown below.
