1,3-Dibenzoyloxybenzene
1. Basic Information
Name: 1,3-Dibenzoyloxybenzene
Alias: Resorcinol dibenzoate
CAS No.: 94-01-9
Molecular Formula: C20H14O4
Molecular Weight: 318.32
Category: Aromatic diester fine chemical intermediate
2. Physical and Chemical Properties
Physical Properties
- Appearance: White crystalline powder
- Odor: Faint mild aromatic ester odor
- Solubility: Soluble in acetone, chloroform, toluene, ethyl acetate; slightly soluble in hot methanol and ethanol; insoluble in water and aliphatic hydrocarbons
- Melting Range: 116–119 °C
- Hygroscopy: Non-hygroscopic under normal ambient humidity
- Aqueous Property: Lipophilic neutral aromatic diester, insoluble in water
Chemical Properties
- Molecular Structure: Benzene ring linked with two benzoyloxy groups at meta positions
- Ester Hydrolysis: Stable under neutral and weak acidic conditions; ester bonds hydrolyze under strong alkali heating to produce resorcinol and benzoic acid
- Thermal Stability: Stable below 140 °C; no obvious decomposition under conventional plastic processing temperature
- Photostability: Moderately sensitive to UV light; long-term illumination causes slight yellowing
- Compatibility: Good compatibility with most resins, plasticizers and organic solvents; incompatible with concentrated strong alkali and strong oxidants
3. Main Application Fields
1. Plastic & Polymer Additive (Core Application)
Internal lubricant and nucleating agent for polyolefin, polyester and PVC resins; improves material surface gloss and molding fluidity
2. Pharmaceutical Synthetic Intermediate
Raw material for synthesizing resorcinol-series ester derivatives and aromatic drug intermediates
3. HPLC Reference Standard
Reference substance for detection of aromatic dibenzoate compounds in fine chemical production

Safety Warning
Mild irritant aromatic diester powder. Dust irritates eyes, respiratory tract and skin. All operations shall be carried out in ventilated fume hoods with dust respirators, chemical-resistant gloves and safety goggles. Avoid long-term contact with strong alkali to prevent hydrolysis. Waste liquid requires organic solvent recovery treatment; solid waste can be incinerated by professional hazardous waste disposal institutions.
