Acetone: A Fundamental Solvent and Multifunctional Chemical Raw Material

Acetone, with the chemical formula C₃H₆O, is the simplest saturated ketone. It is a colorless, transparent, and highly volatile liquid with a distinctive pungent odor. It is miscible with water, ethanol, and a wide range of organic solvents in any proportion. Acetone is primarily obtained as a byproduct in the cumene process for phenol production, and can also be produced through the dehydrogenation of isopropanol. It is one of the highest-volume organic solvents in industrial production.

In the chemical industry, acetone plays multiple roles, serving as a solvent, intermediate, and processing aid.

As a highly effective solvent, acetone possesses exceptional dissolving power for a wide variety of substances, including plastics, resins, oils, and cellulose ethers. It is an indispensable component in industries such as coatings, inks, adhesives, and cleaning agents, where it is commonly used for equipment cleaning, formulation dilution, and surface treatment. In the electronics industry in particular, acetone is widely used for cleaning precision components and optical lenses due to its ability to evaporate completely without leaving residues.

As a chemical intermediate, acetone is a key raw material for synthesizing several important chemicals. It is used in the production of methyl methacrylate (MMA), the core monomer for manufacturing acrylic glass (PMMA), and in the synthesis of bisphenol A, which is further used in epoxy resins and polycarbonates. Additionally, acetone is frequently used as a reaction medium or extraction solvent in the pharmaceutical, pesticide, and cosmetics industries.

It is important to note that acetone is highly flammable and has certain irritating effects. Prolonged exposure may cause skin dryness or nervous system discomfort. Proper ventilation and strict avoidance of open flames are essential when handling it. With the advancement of green chemistry principles, the recovery, recycling, and development of safer alternatives to acetone are gaining increasing attention.
