A chemical compound, CH3COCH3. A colorless liquid with an ethereal odor, it is the first member of the homologous series of aliphatic ketones. Its physical properties include boiling point 56.2°C (133.2°F). melting point -94.8°C (-138.6°F). and specific gravity 0.791. Acetone is used as a solvent for cellulose ethers, cellulose acetate, cellulose nitrate, and other cellulose esters. Cellulose acetate is spun …

A re­arrangement reaction, sometimes known as the Dakin reaction, com­monly used in organic synthesis in which a ketone reacts with a peroxy acid to form an ester. For example, R-CO-R → R-CO-O-R The reaction is equivalent to the in­sertion of an oxygen atom next to the ketone’s carbonyl (>C=O) group. Meta-chloroperbenzoic acid (m-CPBA; ClC6H4.CO.O.OH) and trifluoro­perethanoic acid (CF3.CO.O.OH) are typical …
