Diphenyl Ethers, also known as 1,1'-Oxybisbenzene or Phenoxybenzene, is a versatile organic compound with the distinct formula (C₆H₅)₂O. Recognized by its CAS Registry Number 101-84-8, it is a clear, colorless to pale yellow liquid or crystalline solid with a characteristic mild, pleasant odor.
Its unique structure—two benzene rings linked by an oxygen atom—provides exceptional thermal stability, chemical inertness, and solvent properties. This makes it a critical material in high-temperature industrial applications and specialty chemistry. We supply high-purity Diphenyl Ethers to meet the stringent demands of various advanced industries.

Diphenyl Ethers serves multiple key functions due to its stable and inert nature:
- High-Temperature Heat Transfer Medium: Its primary function is as a component in high-temperature heat transfer fluids and vapor phase reboilers due to its high boiling point and exceptional thermal stability.
- Fragrance Fixative & Modifier: Acts as a fixative and carrier in perfumery, providing longevity and modifying the scent profile of fragrance compositions.
- Chemical Intermediate: Used in the synthesis of more complex chemicals, including polymers, dyes.
- Solvent & Reaction Medium: An effective solvent for certain organic reactions and crystallizations where high-temperature inert media are required.
- Plasticizer & Flame Retardant Component: Used in some specialty polymer formulations.
Our Diphenyl Ethers is essential across several advanced industries:
- Chemical & Petrochemical Processing: As a heat transfer fluid in vapor phase reboilers for distillation columns.
- Perfumery & Cosmetics: As a key ingredient in high-end fragrance formulations for its fixative properties.
- Medical Synthesis: As an intermediate in the production of medical compounds.
- Electrical Engineering: Historically used as a coolant in high-power electrical transformers (part of askarel mixtures).
- Research & Development: As a specialty solvent and reagent in organic synthesis labs.
- Polymer Industry: As a monomer or modifier in the production of high-performance polymers and resins.
We produce Diphenyl Ethers through a controlled, high-purity synthesis process, typically involving the Ullmann Ethers Synthesis or similar high-yield reactions, where phenol derivatives are coupled under specific catalytic conditions. Our process emphasizes:
- Raw Material Selection: Using high-purity starting materials.
- Catalytic Reaction: Optimized for maximum yield and minimal by-products.
- Purification: Multi-stage distillation and crystallization to achieve ≥99.5% purity.
- Quality Control: Rigorous in-process and final testing (GC, HPLC) to ensure specification compliance.
- High Purity & Consistency: We specialize in ≥99.5% purity, ensuring reliable performance for your critical applications.
- Technical Expertise: Decades of experience in aromatic ethers chemistry and application support.
- Global Supply Chain: Reliable logistics for bulk and smaller orders worldwide.
- Full Documentation: Compliant with MSDS (SDS), TDS, COA, and all international regulatory requirements.
- Customization: Ability to tailor specifications (packaging, purity grades) to your specific needs.
- Safety & Sustainability: Commitment to responsible manufacturing and safe handling guidelines.
