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. Its main use is as a chemical intermediate in the manufacture of acetone cyanohydrin for methyl methacrylate, bisphenol A and aldol chemicals. Catalytic dehydrogenation of propanol can be chosen as an alternative synthetic route when high-purity of acetone is required, such as in biomedical applications. A single pass conversion of 85-92% wuth respect to isopropanol, with reactor conditions of 2bar and 350oC, is generally achieved for this process (Turton et. al, n.d as in Tremoulet, Unton, & Feng, 1998). A molten salt will be used a heat source for the endothermic reaction:
The acetone produced in the reactor passes into a phase separator and then into a separation system that includes one stripping and two distillation column.
1.1 The Uses Of Acetone
Acetone is an organic chemical consisting of carbon, hydrogen, and oxygen atoms. It is a clear, flammable liquid at room temperature. It is produced by humans in small amounts through routine biological processes, but can be harmful in very high concentrations. Generally, acetone causes no serious health problems. Acetone is used in a variety of ways both in science and in everyday life. [1]
Most acetone is made during the production of phenol. Phenol is mostly used to make polymers like plastics; it was also the first antiseptic to be discovered, by Joseph Lister. [2]
1. Solvent
Scientists use acetone as a solvent for many different materials, such as plastics or other man-made, petroleum-based substances.
