Ethyl Benzoate
1. Basic Information
Name: Ethyl Benzoate
Alias: Ethyl benzenecarboxylate
CAS No.: 93-89-0
Molecular Formula: C9H10O2
Molecular Weight: 150.17
Category: Synthetic flavor and fragrance raw material, fine chemical intermediate, organic solvent, analytical reagent
2. Physical and Chemical Properties
Physical Properties
- Appearance: Colorless transparent oily liquid
- Odor: Mild sweet fruity, floral and balsamic aroma similar to grape and cherry
- Solubility: Miscible with ethanol, propylene glycol, acetone, toluene and most vegetable oils; slightly soluble in cold water
- Boiling Point: 212–214 °C (760 mmHg)
- Density (20 °C): 1.043–1.047 g/cm3
- Refractive Index nD20: 1.504–1.507
- Flash Point: 88 °C
- Hygroscopy: Non-hygroscopic
- Aqueous property: Neutral aromatic ester, stable in neutral cold water at ambient temperature
Chemical Properties
- Molecular structure: Ethyl ester of benzoic acid with benzene ring and ester functional group
- Ester reactivity: Undergoes hydrolysis under acidic or alkaline heating to produce benzoic acid and ethanol; transesterification occurs with other alcohols
- Ring reactivity: Benzene ring supports electrophilic substitution reactions such as nitration, halogenation and sulfonation
- Photostability: Slightly light-sensitive; long-term direct sunlight causes slow yellowing
- Thermal stability: Stable below 180 °C; prolonged heating near boiling point generates trace acidic decomposition impurities
- Compatibility: Excellent miscibility with flavor solvents, resin and coating systems; incompatible with concentrated strong alkali and strong oxidants under heating
3. Main Application Fields
1. Edible & Daily Fragrance Raw Material (Core Application)
Widely used in grape, berry, peach, vanilla and floral flavor formulations for beverages, candies, baked goods, perfumes, soaps and cosmetics
2. Pharmaceutical Synthetic Intermediate
Precursor for synthesizing benzoic acid derivatives, preservatives and ester-type drug intermediates
3. Organic Synthesis Laboratory Reagent
Standard aromatic ester substrate for hydrolysis, transesterification and benzene ring modification research
4. Industrial Coating Auxiliary
Low-volatility solvent and odor fixative for solvent-based printing inks and surface coatings
