Asetüülbenseen

Asetüülbenseen, also known as acetophenone, is an organic compound with the chemical formula C6H5COCH3. It is the simplest aromatic ketone. In its pure form, it is a white crystalline solid with a strong, sweet, floral odor, often described as resembling orange blossoms or hawthorn. It is naturally occurring in some plants and foods, contributing to their aroma.

Acetophenone is synthesized industrially through several methods, primarily the Friedel-Crafts acylation of benzene with acetyl chloride or acetic anhydride in the presence of a Lewis acid catalyst such as aluminum chloride. It can also be produced as a byproduct of the oxidation of ethylbenzene.

This compound finds applications in various industries. It is used as a fragrance ingredient in perfumes, soaps, and detergents due to its pleasant scent. In the pharmaceutical industry, it serves as a precursor in the synthesis of various drugs. Acetophenone is also employed as a photoinitiator in UV-curing applications, such as in inks, coatings, and adhesives. Furthermore, it is used as a solvent for certain resins and polymers.

Acetophenone is moderately soluble in water but highly soluble in organic solvents like ethanol and ether. It has a relatively low melting point and a higher boiling point. While generally considered to have low toxicity, prolonged exposure or ingestion should be avoided.
