5-UNDECANONE Chemical Properties,Uses,Production

Aroma

Oily, but slightly pungent-fruity, herbaceous odor of moderate to poor tenacity. Less winey than ,MethylnonyIketone (a naturally occurring isomer), and not quite as Orange-like. Greener and fruitier.

Physical properties

Colorless oily liquid. Solidifies in the cold to an opaque mass. Insoluble in water, soluble in alcohol and oils. BP. 214°C.

Uses

5-Undecanone is a useful research chemical used in the preparation of carboxaldehydes, ketones, and esters via iodine-mediated oxidation of alcohols.

Application

5-UNDECANONE rarely offered commercially, has been suggested for use in perfume compositions. However, after so much discussion about the possible hazards of using certain ketones (including the named isomer) in perfumes for cosmetic preparations, chances are that this ketone has little or no future in perfumery.

Production Methods

5-UNDECANONE can be produced from Valenc and Heptanoic acids by heating of the mixture over Thorium oxide to about 450°C.
