Benzyl Acetate
SINOBIO
2932290090
Benzyl Acetate (benzyl acetate) is a colorless, transparent liquid with a jasmine-like fragrance. Its key information can be explored from four dimensions: chemical properties, synthesis methods, application areas, and safety characteristics:
1. Molecular Structure
Molecular formula: C₉H₁₀O₂
Molecular weight: 150.17 g/mol
Structural formula: A benzene ring is connected to an acetate ester group (-COOCH₃) via a methylene group (-CH₂), forming a stable aromatic ester structure.
2. Physical Properties
Appearance: Colorless, transparent liquid with a rich jasmine fragrance.
Density: 1.055 g/cm³ (20°C).
Boiling point: 213.5°C (at atmospheric pressure), 102.2°C (flash point).
Solubility: Sparingly soluble in water (0.23% w/v at 23°C), readily soluble in organic solvents such as ethanol, ether, and acetone.
Stability: Stable at room temperature, but may decompose upon exposure to strong acids, strong bases, or high temperatures.
3. Chemical reactions
Hydrolysis reaction: Slowly hydrolyzes under alkaline conditions to form acetic acid and benzyl alcohol (10% hydrolysis in 1 hour at 20°C, reaching 46% in 5 hours).
Chlorination reaction: Reacts with chlorine gas at 150–170°C to form benzyl chloride and acetyl chloride.
Reduction reaction: Reacts with sodium metal at elevated temperatures to form benzyl cinnamate hydride and dibenzyl ether.
Benzyl Acetate is mainly used as the main component of jasmine and other extracts, soap flavoring agents and other spices and essences.

Floral Flavoring: The core components of essential oils such as jasmine, ylang-ylang, and orange blossom, widely used in perfumes, cosmetics, and soap flavorings.
Fruit Flavoring: Used in small quantities in edible flavorings such as pear, apple, and banana, imparting a fresh fruity aroma.
Solves oils, nitrocellulose, and cellulose acetate, used as solvents in shellac paint, alkyd resins, dyes, and printing inks.
Replaces isopropyl alcohol in coatings to enhance coating gloss and adhesion.
Biological synthesis: Through metabolic engineering of Escherichia coli, efficiently synthesizes benzyl acetate from glucose for use in green chemistry.
Standard substances: Used as calibration standards for gas chromatography (GC) or mass spectrometry (MS) in analytical chemistry.
The core advantages of Benzyl Acetate (benzyl acetate) lie in its irreplaceable role as a natural jasmine fragrance, its high-performance solvent properties, and its cost-effective applications across multiple industries. A detailed analysis is provided below:
It is a primary component in floral-type fragrances such as jasmine, gardenia, and magnolia, and serves as a harmonizing agent in fragrances like rose, orange blossom, and lily of the valley, enhancing their freshness.
It exhibits good biodegradability, breaking down in the environment via microbial action, thereby reducing the risk of long-term pollution.
Fragrance industry:
As a base component of jasmine fragrance, its cost is only 1/10 to 1/20 of natural jasmine extract, significantly reducing fragrance formulation costs. In food fragrances, it can be added according to production requirements (e.g., 760 mg/kg in chewing gum, 34 mg/kg in candy), allowing flexible control of usage.
Solvent Industry:
Replaces harmful solvents such as chlorinated hydrocarbons, meets environmental regulations, and reduces corporate environmental investment. In industries such as textiles, dyes, and inks, its dissolution performance and cost-effectiveness outperform many specialized solvents.
Emerging Fields:
Biological Synthesis: Through metabolic engineering of E. coli, it can efficiently synthesize benzyl acetate from glucose, providing a new pathway for green chemistry.
