3Pentanone

3-Pentanone, also known as diethyl ketone, is a chemical compound with the formula (C2H5)2CO. It is a ketone and is structurally symmetrical. At room temperature, 3-pentanone is a colorless liquid with a characteristic ether-like odor. It is moderately soluble in water and miscible with most organic solvents. The compound is flammable and its vapors can form explosive mixtures with air.

3-Pentanone is produced industrially through several methods, including the catalytic oxidation of 3-pentanol or through the reaction of propionyl chloride with ethylmagnesium bromide. It finds use as a solvent for various resins, lacquers, and polymers. It can also serve as an intermediate in the synthesis of other organic chemicals. While not as commonly encountered as some other ketones, its specific solvent properties make it valuable in certain industrial applications. Safety precautions should be taken when handling 3-pentanone due to its flammability and potential irritant properties.
