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.

Description

Isobornyl acetate has a pleasant, camphor-like odor reminiscent of some varieties of pine needles and hemlock, and a fresh, burning taste. May be prepared by treatment of camphene with acetic acid, usually in the presence of a catalyst; also by acetylation of isobomeol; depending on the starting material (d-camphene or ι-camphene), the resulting acetate may exhibit a slight optical activity; the commercial product is considered to be optically inactive.

Chemical Properties

Colorless liquid; pine-needle odor.Soluble in most fixed oils and in mineral oil; insoluble in glycerol and water. Combustible.

Chemical Properties

Isobornyl Acetate has been identified in a number of essential oils. It is a colorless liquid with a pleasant, pine-needle odor. Isobornyl acetate is prepared from camphene and acetic acid in the presence of acidic catalysts (e.g., sulfuric acid) or on a styrene–divinylbenzene acid ion-exchanger.
Isobornyl acetate is used in large amounts for perfuming soaps, bath products, and air fresheners. However, the major use of isobornyl acetate is as an intermediate in the production of camphor.

Uses

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

Preparation

By treatment of camphene with acetic acid, usually in the presence of a catalyst; also by acetylation of isoborneol; depend[1]ing 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
