Diphenyl oxide

Diphenyl oxide is a chemical compound composed of two phenyl (C6H5) groups connected by an oxygen (O) atom. It is a colorless, crystalline substance with a slightly sweet odor. Diphenyl oxide is commonly used as a heat transfer fluid in high-temperature applications due to its excellent thermal stability and relatively low melting point. It is also utilized as a solvent in organic chemistry and serves as an intermediate in the synthesis of various organic compounds.
