Description |
2-Nonanone has a characteristic rue odor and a rose and teα-like flavor. May be prepared by dry distillation of barium caprylate and barium acetate at 0.5 - 2 mmHg; or by oxidation of methyl heptyl carbinol at room temperature using chromic acid; it can be isolated also from natural products by fractional distillation. |
