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

Practical 2.1- The Effect of Temperature on Membranes Objective To investigate the effect of temperature on membrane structure Introduction Beetroot Pigments Beetroots contain Betalains which are the red pigments present in the cell vacuole. Betalains are soluble in water and they contain nitrogen. Betalains extracted from beetroot is commonly used as food dye because it is not known to cause any allergic reactions.

stress that various alcohols have on biological membranes. Using five solutions of differing alcohol concentration for each of the three alcohols; methanol‚ ethanol‚ and 1-propanol and a small slice of beet‚ the stirred solution was placed into a plastic cuvette and then into a spectrophotometer and the absorbance of alcohol solutions were determined in order to conclude which alcohol and concentration of alcohol had the greatest effect on biological membranes. The results showed that the most non-polar

Introduction To determine the effects of stressful experimental treatments on living membranes we are going to examine how fresh beets roots react when they are exposed to different temperatures. Membranes are an important feature of plant cells and they act as a barrier that separates the interior of the cell from the external environment (Campbell 133). They organize specific chemicals and reactions into specific compartments within the cell. Generally‚ cell membranes consist of phospholipids bilayer

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

the effect of different concentrations of ethanol on the permeability of beetroot cell membranes. Prediction: By exposing a membrane to a solvent‚ ethanol‚ it will increase its permeability. So the higher the concentration of the solvent‚ the more permeable the membrane will be. But if the concentration of the ethanol is beyond a certain limit‚ it may break down the cell membrane to the point where there is in fact no overall effect as the ethanol would disturb the lipids in the membrane.

Investigating the effect of temperature on plant cell membranes The purpose of this activity is: • to practise experimental and investigative skills • to investigate the effect of temperature on cell membrane structures Procedure SAFETY: Always carry scalpels clasped to a tile and with the tip pointing away from you. Beetroot cells contain pigments called betalains that give the tissue its dark purple-red colour. The pigment is contained in the cell vacuole. Investigation
