• Molecular Weight: 196.29 g/mol
• Boiling Point: Approximately 230°C
• Density: 0.89 g/cm_

Chemical Properties

Geranyl acetate is relatively stable but can undergo hydrolysis in the presence of acids or bases to yield geraniol and acetic acid. It is soluble in organic solvents such as ethanol and diethyl ether but has limited solubility in water.

Occurrence

Geranyl acetate is found in the essential oils of several plants, including lemongrass, coriander, and geranium. It contributes to the characteristic scents of these plants and is often extracted for use in perfumes and flavorings.

Uses

Geranyl acetate is primarily used in the fragrance industry due to its pleasant aroma. It is a common ingredient in perfumes, soaps, and cosmetics. Additionally, it is used as a flavoring agent in the food industry, imparting a fruity and floral taste to various products.

Synthesis

Geranyl acetate can be synthesized through the esterification of geraniol with acetic acid. This reaction typically requires an acid catalyst, such as sulfuric acid, to proceed efficiently.

Safety and Toxicology

Geranyl acetate is generally regarded as safe when used in appropriate quantities. However, as with many essential oil components, it can cause skin irritation in sensitive individuals. Proper handling and dilution are recommended to minimize any potential adverse effects.
