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 colorless 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.
