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

Introduction The production of acetone and butanol by means of solvent-producing strains of Clostridium spp. was one of the first large-scale industrial fermentation processes to be developed‚and during the first part of this century it ranked second in importance only to ethanol fermentation. The reason for the almost total demise of this fermentation in the early 1960s was the inability of the fermentation process to compete economically with the chemical synthesis of solvents. However‚ interest

Acetone is an extremely popular solvent that is used in rubber‚ resin‚ plastics‚ lacquers‚ varnishes‚ and rubber cements. It is also used in the creation of fats‚ oils‚ and waxes where is a primary component. Acetone has many uses in modern technology including those that relate to the medical field and various domestic uses. It is a very important organic compound found in everyday life‚ but it is also a toxin and can be an extremely dangerous environmental pollutant. Acetone has many valuable
Premium Pollution Acetone Solvent
Background of the Study Familiar household uses of acetone are as the active ingredient in nail polish removers and as paint thinner. Acetone can also be used for medical and cosmetic uses‚ such as applying acetone with alcohol for acne treatments to peel dry skin. It can also remove residues from glass and porcelain and it can also remove super glue from the skin. Perhaps‚ acetone is very useful in our everyday lives. Acetone is also known to remove ball pen marks on fabrics and clothings

Permanent marker can be removed using a dry erase marker on certain surfaces such as a whiteboard as it contains acetone. Alcohol based markers such as Sharpies are said to be safer‚ with water-based markers being the safest of all.
