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. |
