3-Pentanone

3-Pentanone

3-Pentanone is an organic compound with the chemical formula C5H10O. It is a colorless liquid with a pleasant, ether-like odor. It is one of the ketones, a class of compounds that contain a carbonyl group (C=O) bonded to two other carbon atoms.

Chemical Properties

3-Pentanone is a ketone due to the presence of a carbonyl group. It is a polar molecule, with the carbonyl group creating a region of partial positive charge and the carbon atoms creating regions of partial negative charge. This polarity allows 3-pentanone to engage in hydrogen bonding with other polar molecules.

Physical Properties

3-Pentanone is a colorless liquid at room temperature. It has a pleasant, ether-like odor. It is less dense than water and its vapors are heavier than air. It is soluble in water and can be mixed with alcohol and ether.

Production and Uses

3-Pentanone is produced industrially through the oxidation of secondary alcohols. It is used as a solvent in the manufacture of pharmaceuticals and as a flavoring agent in the food industry. It is also used in the synthesis of other organic compounds.

Health Effects

Exposure to 3-pentanone can cause irritation to the eyes, skin, and respiratory tract. It can also cause nausea, headache, and dizziness. Long-term exposure can lead to damage to the liver and kidneys.
