Acetophenone is the organic compound with the formula $ C_6H_5-CO-CH_3$. It is the simplest aromatic ketone. This colourless, viscous liquid is a precursor to useful resins and fragrances.
Acetophenone can be obtained by a variety of methods. In industry, acetophenone is recovered as a by-product of the oxidation of ethylbenzene, which mainly gives ethylbenzene hydroperoxide for use in the production of propylene oxide.
