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 a pleasant, camphor-like odor reminiscent of some varieties of pine needles and hemlock and a
fresh, burning taste
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.
Occurrence
Reported found in thymus, Parmesan cheese, dill herb, Ocimum basilicum, rosemary and custard apple
Preparation
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
