Overview
Diphenyl ether, also known as phenyl ether, is an organic compound with the formula (C6H5)2O. It is a colorless to pale yellow liquid or crystalline solid with a mild aromatic odor. The compound is chemically stable and exhibits low reactivity, making it useful in various industrial applications. First synthesized in the 19th century, diphenyl ether has become an important chemical in multiple industries. Its stability at high temperatures and compatibility with other organic compounds contribute to its versatility as a reagent and functional material.
Physical and Chemical Properties
Diphenyl ether has a molecular weight of 170.21 g/mol and exists as either a liquid or solid depending on temperature, with a melting point of 28°C and boiling point of 259°C. The compound is denser than water (1.07 g/cm³) but insoluble in it, though it readily dissolves in most organic solvents. Chemically, diphenyl ether is relatively inert due to the stability of its ether linkage and aromatic rings. It resists hydrolysis and maintains stability under moderate heating conditions. These properties make it particularly valuable as a heat transfer fluid in high-temperature applications.
Main Applications
One of the primary uses of diphenyl ether is as a high-temperature heat transfer fluid, often in mixtures with biphenyl (known as Dowtherm A). These mixtures can operate at temperatures up to 400°C without significant decomposition, making them ideal for industrial heating systems. In the fragrance industry, diphenyl ether serves as a fixative and contributes to perfumes' floral notes. It's also used as an intermediate in organic synthesis, particularly in the production of polyphenyl ether polymers that find applications in electronics and aerospace industries.
Safety and Storage
While diphenyl ether is not highly toxic, it can cause irritation to skin, eyes, and respiratory system upon prolonged exposure. Proper personal protective equipment including gloves and safety goggles should be worn when handling this chemical. Storage recommendations include keeping containers tightly closed in a cool, well-ventilated area away from strong oxidizing agents. The compound is stable under normal conditions but may decompose at high temperatures, producing carbon monoxide and other hazardous gases.
B2B Procurement Guide
When procuring diphenyl ether commercially, buyers should specify required purity levels which typically range from 98% to 99.9% for different applications. Technical grade is sufficient for heat transfer applications, while higher purity is needed for pharmaceutical or fragrance uses. Reliable suppliers should provide material safety data sheets (MSDS) and certificates of analysis. For international shipments, verify compliance with transportation regulations as diphenyl ether is classified as a hazardous material in some jurisdictions. Bulk purchases often offer significant cost savings.
