1,6-Dioxacycloheptadecan-7-one

(6707-60-4)
The odor of this lactone is comparable to that of 15-pentadecanolide, but less intense. It is prepared by reacting methyl 11- bromoundecanoate with the monosodium salt of 1,4-butanediol. The resulting methyl 16-hydroxy-12-oxapalmitate is condensed to the corresponding polyester, which is subsequently depolymerized.

Lactone refers to an organic substance that contains both a carboxyl group and a hydroxyl group in the same molecule, and the two are dehydrated. Organic compounds with one and only one ester group in the ring. Common ones are x=2, 3 or 4, which are called β-, γ- or δ-lactones, respectively. They are generally insoluble in water, easily soluble in organic solvents such as ethanol and ether, and their density is generally lower than that of water.
