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.

    Although the yield of our reaction was mediocre, the purity of the sample (as analyzed by 1H and 13C NMR) was poor. There are many factors that may have caused poor purity, of which include reaction incompletion during exposure to microwave radiation, poor mixing, and poor product isolation during column chromatography. As seen in the 1H NMR spectrum, impurity peaks (>10%) corresponding to methyl (triphenylphosphoranylidene) acetate, acetone, ethyl acetate, and hexane were identified. The phosphonium ylide peak indicates that the reaction did not go to completion (leftover starting material). Meanwhile, the acetone, ethyl acetate, and hexane peaks show there was residual solvent in the sample submitted for NMR analysis (compounds were not in reaction scheme). Because acetone, ethyl acetate, and hexane are volatile, we deduced that our evaporation of the final product was…

    In this experiment, acetanilide was used as the pure organic compound. Acetylation of aniline and acetic anhydride yields the crude product or crude acetanilide. The crude acetanilide was purified by dissolving it in hot water and then the solution was cooled slowly by placing in an ice bath. The yielded crystals were pure acetanilide since molecules of other compounds present in the crude acetanilide were excluded from the growing crystal lattice. Lattice is a fixed and rigid arrangement of atoms, molecules or ions. The melting point of the pure acetanilide was then determined by placing it in a capillary tube then immersed it to the oil bath with a thermometer and was monitored. The percentage yield calculated was 37.04%.…

    Since ancient times, vinegar has been used for different purposes like cleaning, cooking, gardening, etc. In gardening, it is used as a herbicide. Vinegar is an important element in organic gardening, as it has the capability of killing the weeds. Vinegar contains natural acetic acid which helps in destroying the weeds. Acetic acid (systematically named ethanoic acid is an Acetic acid (systematically named ethanoic acid is an organic compound with the chemical formula CH3CO2H (also written as CH3COOH or C2H4O2). It is a colourless liquid that when undiluted is also called glacial acetic acid. Acetic acid is the main component of vinegar (apart from water; vinegar is roughly 8% acetic acid by volume), and has a distinctive sour taste and pungent smell. Besides its production as household vinegar, it is mainly produced as a precursor to polyvinylacetate and cellulose acetate. Although it is classified as a weak acid, concentrated acetic acid is corrosive, and attacks the skin with the chemical formula CH3CO2H (also written as CH3COOH or C2H4O2).

Although it is classified weak acid concentrated acetic acid is corrosive, and attacks the skin. More the content of acetic acid, more strong is the weed killer. For culinary purposes, the content of acetic acid in the vinegar is merely 5%. The content of acetic acid in regular household vinegar is also 5%. This might work on young weeds but, for killing the mature ones, large amount of vinegar is required. Another option for killing mature weeds is by repeatedly…

    In this experiment the substances that were used were acetone, methanol, water, 1- butanol and ethyl acetate. Acetone is the organic compound with the formula (CH₃)₂CO. It is a colorless, volatile, flammable liquid, and is the simplest ketone. It takes 21 seconds for it to completely disappear. It was the first to evaporate among all tested substances. The reason for this is that this molecule is not attracted to another molecule of Acetone by hydrogen bonding because although there are hydrogen molecules they are not bonded to an Oxygen, Fluorine or Nitrogen. In other words it has no H's that are bonded to F, O, N, or Cl - i.e. there are no slightly positive H atoms. Acetone molecules attract each other since they are both having permanent dipoles. This type of IMF, which is weaker than H bonds, is called dipole-dipole interactions. The weaker the intermolecular…
