Acetone can be made using a wide variety of methods, although as of 2015, approximately 90 percent of acetone produced in the United States is made through the hydrolysis of cumene hydroperoxide. Earlier methods of acetone production included carbohydrate fermentation of molasses or corn and thermal decomposition of calcium acetate.
Cumene peroxidation involves the splitting of cumene hydroperoxide in the presence of sulphuric acid, which results in acetone and phenol. Under normal circumstances, this produces approximately 0.62 tons of acetone for every 1 ton of phenol. This process became more popular in the 1960s due to the increased supply of propylene.
Acetone, also known as dimethylketone, is a colorless liquid with a somewhat sweet smell. It is one of the most used chemical solvents in the world. Although it is extremely flammable, acetone has a very low toxicity and is naturally produced by the body in small amounts.
According to Dow Chemicals, approximately 70 percent of the acetone produced in the world is used to manufacture other chemicals, and about 12 percent is used in its pure form as a solvent. Approximately 6 percent of acetone is used to manufacture pharmaceuticals. Some of the other chemicals produced with acetone include adhesives, general purpose cements, paint thinner, nail polish remover and other cosmetic products.Learn More
The chemical formula for the bromine gas is Br2. This signifies that the bromine molecule contains only two "Br" atoms, which form a covalent bond between them.Full Answer >
Expendable property is property that gets completely consumed through use or property that loses its identity after it is used. For example, a ream of printer paper gets completely used up after it has been printed on, so it no longer serves its function after use, which means it is expendable property.Full Answer >
The chemical equation for the neutralization of sulfuric acid and sodium hydroxide can be written as H2SO4 + 2NaOH —> 2H2O + 2NaSO4. The equation shows that sulfuric acid has an equivalent value of 2, which means that one molecule of H2SO4 can neutralize 2 molecules of a base, such as sodium hydroxide, which has an equivalent value of 1. The neutralization equation also represents one of the production processes that produces sodium sulfate, the sodium salt of sulfuric acid and is used to neutralize surplus sulfuric acid by sodium hydroxide during the making of rayon.Full Answer >
