Diphenyl ether
CAS No.: 101-84-8
Molecular Formula: C12H10O
Molecular Weight: 170.21
Physical and Chemical Properties
- Appearance: Colorless crystals or pale yellow oily liquid with a mild geranium-like odor.
- Melting Point: 26–30 °C.
- Boiling Point: 257–259 °C (760 mmHg).
- Density: 1.073 g/mL at 25 °C.
- Refractive Index: 1.5780 (n20/D).
- Flash Point: 115 °C (closed cup).
- Solubility: Insoluble in water, dilute acids and alkalis; soluble in ethanol, ether, benzene, chloroform and glacial acetic acid.
- Stability: Stable at room temperature and under normal conditions; resistant to weak acids and bases; decomposes under strong light and high temperature; may form peroxides upon prolonged exposure to air.
Application
- Heat transfer medium: Excellent thermal stability, often mixed with biphenyl as a high-temperature heat carrier for industrial heating systems.
- Fragrance industry: Used in low-grade soaps, detergents and floral cosmetics; serves as a fixative and fragrance component.
- Flame retardant intermediates: Raw material for brominated diphenyl ethers (e.g., decabromodiphenyl oxide) used in plastics, textiles and electronics.
- Organic synthesis: Intermediate for pharmaceuticals, pesticides, dyes and polymer materials.
- Laboratory reagent: High-boiling solvent for high-temperature organic reactions (e.g., cyclization, condensation).
Storage Condition
Store in a cool, dry, well-ventilated warehouse. Keep tightly sealed and away from direct sunlight, heat sources, strong oxidants and strong acids. Avoid long-term exposure to air to prevent peroxide formation.
