hexan2one

Hexan-2-one, also known as 2-hexanone or sec-hexanone, is an aliphatic ketone with the molecular formula C6H12O. Its structure features a carbonyl group at the second carbon of a six-carbon chain: CH3-CO-CH2-CH2-CH2-CH3.

Physically, hexan-2-one is a colorless liquid with a moderately strong odor typical of many ketones. It has a boiling point in the low hundreds of degrees Celsius and is immiscible with water but soluble in many organic solvents such as acetone, ether, and benzene. It is flammable and should be stored away from sources of ignition.

Hexan-2-one is primarily produced commercially by oxidation of secondary alcohols, notably 2-hexanol, or by catalytic oxidation of appropriate hexane derivatives. It can also be formed as a byproduct in certain hydrocarbon processing streams. In organic synthesis, it serves as a versatile solvent and as an intermediate in the production of fragrances, flavors, and various chemical intermediates.

Applications include use as a solvent in coatings, inks, extraction processes, and as a reagent in chemical syntheses. Its moderate polarity allows it to dissolve a wide range of organic compounds, though its water solubility remains limited.

Safety: Hexan-2-one is a flammable irritant. Vapors can cause dizziness or irritation of the eyes, skin, and respiratory tract. Proper ventilation, protective equipment, and storage in a cool, well-ventilated area away from oxidizers and ignition sources are recommended.
