Geranyl acetate is a multifunctional compound primarily used in the following fields:
Essence and fragrance: Used to formulate floral essences such as rose, orange blossom, and osmanthus, and as a modifier to enhance sweetness; also an important ingredient in raw materials such as artificial bay leaf oil and bergamot oil.
Edible flavor: According to the GB 2760-96 standard, it is allowed to be used in food, mainly for apple, pear, berry and other fruit-flavored essences, and can also be applied to wine, spicy and other edible essences.
Daily chemical products: often added as fragrances in cosmetics, soaps, etc.

The production methods of (geranyl acetate) mainly include natural extraction and chemical synthesis.
Natural extraction method: Geranyl acetate occurs naturally in aromatic oils such as camphor oil, ylang-ylang oil, neroli oil, orange leaf oil, coriander seed oil, and lemongrass oil. It can be directly extracted from these natural sources through methods such as distillation.
Chemical synthesis method: It is primarily prepared through the esterification reaction of geraniol. Common routes include: Acetic anhydride method: Geraniol reacts with acetic anhydride catalyzed by sodium acetate at room temperature, with a yield of nearly 90%. It is then purified through washing and vacuum distillation.
Acetic anhydride method: In the presence of mineral acid (such as sulfuric acid), geraniol reacts with sodium acetate under the action of acetic anhydride.
In addition, the literature also mentions a method involving esterification through azeotropic distillation of acetic acid and isopropanol in a benzene solution in the presence of trace sulfuric acid, but this route may not be mainstream.
