Isobornyl acetate Usage And Synthesis

Description

Isobornyl acetate is a kind of acetate ester. It can be manufactured through the esterification between acetate and camphene. It is a kind of flavoring agent with fragrance. It can be used as the intermediate needed for producing medical synthetic camphor.

Chemical Properties

Isobornyl acetate is a colorless liquid, has a pleasant, camphor-like odor reminiscent of some varieties of pine needles and hemlock and a fresh, burning taste.

Occurrence

Reported found in thymus, Parmesan cheese, dill herb, Ocimum basilicum, rosemary and custard apple

Uses

Isobornyl acetate is one of the most important chemicals used in the perfumery industry. It is used in toiletries and soaps as a flavoring agent and antiseptics. One of main applications is as an intermediate to produce camphor.

Uses

Compounding pine-needle odors, toilet waters, bath preparations, antiseptics, theater sprays, soaps, making synthetic camphor, flavoring agent.

Preparation

Isobornyl Acetate is prepared by treatment of camphene with acetic acid, usually in the presence of a catalyst; also by acetylation of isoborneol; depending on the starting material (d-camphene or l-camphene), the resulting acetate may exhibit slight optical activity; the commercial product is considered to be optically inactive.

Aroma threshold values

Aroma characteristics at 1.0%: camphoraceous woody,sweet, citrus and herbal with “Irish Spring” soapy nuances

Taste threshold values

Taste characteristics at 2 to 10 ppm: camphoraceous, woody, terpy and piney with a spicy, herbal and slightly citrus nuance

Hazard

Isobornyl acetate is generally considered non-toxic, but there have been some reports of irritation and sensitization reactions in individuals exposed to high concentrations of the compound.
