What is diphenyl ether used for?
1. Heat Transfer Fluid (Thermal Fluid)
Diphenyl ether is a key component in high-temperature heat transfer fluids (e.g., Dowtherm A, a mixture of diphenyl ether and biphenyl).
Used in industrial processes requiring precise temperature control at elevated temperatures (up to ~350°C), such as: Chemical reactors, distillation columns, and polymerization processes. Food processing (e.g., baking, frying), plastics manufacturing, and pharmaceutical synthesis.
2. Fragrance and Flavor Industry
Certain derivatives of diphenyl ether (e.g., vanillin ethers or aromatic ethers) are used in perfumes and cosmetics for their warm, sweet, or vanilla-like scents.
3. Solvent and Industrial Applications
Diphenyl ether is acts as a solvent for resins, polymers, oils, and waxes in: Coatings, paints, and inks (to improve flow and film formation).Adhesives and sealants (to dissolve components and adjust viscosity).
Diphenyl oxide is used in the production of specialty chemicals, such as: Polyimides (high-performance polymers for aerospace and electronics).
4. Agrochemicals and Pesticides
Serves as an intermediate in the synthesis of certain insecticides and herbicides.
Its aromatic structure can be modified to create bioactive compounds for agricultural use.
5. Polymer Industry
Phenyl ether is used as a plasticizer or stabilizer in some polymer formulations to improve flexibility and heat resistance.
A precursor in the production of flame-retardant materials and specialty resins.
