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. |
