Acetone - C3H6O

What is Acetone?

Acetone is a highly flammable organic compound. This organic solvent has a chemical formula C3H6O. It is also known as propanone. It is found in the exhaust from vehicles, plants, trees and forest fires. It is also found in the human body usually present in urine and blood. It is colourless and volatile. It is miscible in water, ether, ethanol and has a pungent, floral or irritating smell. It is widely used as an antiseptic and solvent. Alchemists were the first to produce acetone. It is produced with the dry distillation of metal acetates. Currently, acetone is produced by propylene either by the direct or indirect method. Almost 83% of acetone is produced during the cumene process. Also, there are other older methods to produce acetone.

Frequently Asked Questions

What are the uses of acetone?

Acetone is widely used as an industrial solvent. It also serves as a precursor to methyl methacrylate. This process begins with the conversion of acetone into acetone cyanohydrin. Many synthetic fibres and plastics can be dissolved in acetone.

How is acetone produced?

Acetone is derived from propylene, directly or indirectly. The cumene cycle produces approximately 83 per cent of the global acetone production. As a result, the production of acetone is tied to the development of phenols. Benzene is alkylated with propylene in the cumene cycle to obtain cumene, which is oxidized by the environment to create phenol and acetone

Comment on the keto-enol tautomerism exhibited by acetone

As is the case with most ketones, acetone exhibits keto-enol tautomerism in which the “keto” structure (CH3)2C= O is in equilibrium with the enol (CH3)C(OH)=(CH2) structure. Just 0.00000024 per cent of the molecules are in the form of enol in acetone vapour at room temperature.
