Acetone: Properties and Applications in Laboratory and Industrial Settings

What is acetone and how is it chemically structured?

Acetone, also known as propanone, is a simple ketone with the chemical formula CH₃COCH₃. It is the smallest ketone and is highly volatile, flammable, and miscible with water, ethanol, and ether. Its low boiling point (56 °C) and high solubility make it ideal for use in cleaning and extraction processes. Acetone is produced industrially via the cumene process and is also a natural metabolic by-product in humans.

How is acetone used in laboratory and industrial settings?

In laboratory environments, acetone is widely used for cleaning glassware due to its ability to dissolve oils, resins, and organic residues without leaving a film. It is also employed in chromatography, as a solvent in organic synthesis, and in the preparation of reagents. In industry, acetone serves as a precursor in the production of methyl methacrylate (used in plastics and resins), bisphenol A, and pharmaceuticals. Its low toxicity and rapid evaporation make it a preferred solvent in many applications, though its flammability requires careful handling.

What safety and regulatory considerations apply to acetone?

Acetone is classified as a flammable liquid (GHS hazard class 2) and is regulated under REACH and TSCA. It is not classified as a carcinogen but can cause irritation to skin, eyes, and respiratory tract with prolonged exposure. Proper ventilation, flame-proof storage, and personal protective equipment are essential. Safety data sheets (SDS) and certificates of analysis (CoA) are required for procurement in regulated environments.
