Production method
- α,ω-Hexadecanedinitrile is produced by the condensation and hydrolysis of N-Ethyl N-Phenylaminolithium in ether solution with N-Ethyl N-Phenylaminolithium as catalyst.
- It can be obtained from natural raw material neuronic acid by oxidation to α,ω-pentadecanedioic acid, and then reduced by esterification and cyclization to obtain cyclopentadecanone.
Applications
- It has been widely used in the formulation of fragrances since 50 years ago, as its aroma is softer than musk ketone, and its scenting effect is similar to that of pentadecanoide. Usually the concentration in the final product is 0.005% to 0.06% for soaps; 0.0005% to 0.006% for detergents; 0.04% to 1% for perfumes; 0.0025% to 0.01% for creams and others. In edible flavours the dosage and range is limited by its unpleasant taste with little use, drinks, candy, chewing gum and oral products with a dosage of 0.03mg/kg. also used as a solvent for sterols, carotenoids and azo dyes.
- Used in high grade perfume, can increase the powder and animal fragrance, can play a harmonious role with a variety of fragrance, even if added to a small amount of effect is very significant. In the daily chemical industry, it is used as a soap fragrance, detergent fragrance, perfume fragrance, cream fragrance, etc.

Toxicity and ecology of cyclopentadecanone
Toxicological data on cyclopentadecanone:
- Skin/eye irritation data: Standard Draize test for rabbits in direct contact with skin: 500 mg/24H
- Acute toxicity: Oral rat: LD50>5g/kg and dermal LD50>5g/kg. no mortality in mice at an intraperitoneal dose of 11.25mmol/kg over 24h. No mortality in 4 days at a dose of 8.92 mmol/kg. Oral doses of >45mmol/kg did not cause mortality in mice. Acute tests on mice showed no specific pathological reactions, but with increasing doses degenerative liver-like nephritis in the central ducts of the body and minimal pancreatic necrosis were observed. 3. The substance was applied to normal or damaged rabbit skin under closed conditions and showed mild irritation after 24 h. Concentrations diluted to 10% were made into petroleum jelly preparations and did not produce irritation after 48 h in closed skin contact tests in humans, and also did not produce sensitization in maximum tests in humans.
Ecological data on cyclopentadecanone:
Generally non-hazardous to water, do not discharge into the surrounding environment without government permission.
