2-Undecanone Usage And Synthesis


Chemical Properties

colourless liquid

Chemical Properties

2-Undecanone has a characteristic rue odor with a sweet flavor reminiscent of peach (on dilution).

Uses

In the compounding of some synthetic essential oils. As fragrance additive in soaps, detergents, creams, lotions, and perfume. As dog and cat repellant.

Definition

ChEBI: A dialkyl ketone with methyl and nonyl as the two alkyl groups.

Preparation

Can be isolated from natural oils by fractional distillation; also by dry distillation of calcium acetate and calcium caprylate, or by boiling octylacetoacetic acid ethyl ester with and alcoholic KOH solution.

Aroma threshold values

Detection: 7 to 82 ppb

Taste threshold values

Taste characteristics at 30 ppm: waxy and fruity with creamy cheese notes

Safety Profile

Moderately toxic by ingestion. Combustible when exposed to heat or flame; can react with oxidizing materials. To fight fLt-e, use CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also KETONES.
