Product Introduction
Diphenyl Oxide, also known as diphenyl ether, is colorless or light yellow transparent liquid with a geranium smell. It is soluble in alcohol, benzene, diethyl ether and glacial acetic acid, insoluble in water. Diphenyl Oxide is widely used in organic synthesis and perfumery fields, and is also the crucial raw material for producing heat transfer fluid.

Heat Transfer Fluid

Diphenyl oxide is one of the important components of biphenyl/diphenyl oxide heat transfer fluid. The optimal usage temperature range of biphenyl/diphenyl oxide fluid (SCHULTZ® S740) is 12℃400℃.



Because of its odor reminiscent of scented geranium, as well as its stability and low price, diphenyl oxide is used widely in soap perfumes, synthetic detergent and other daily perfumes.


Organic Synthesis

As the organic synthetic intermediate, diphenyl oxide is used to produce resin, surfactant and other organic products. The down-stream products of these organics could be emulgator, leveling agent, detergent and de-misting agent.


Fine Chemical Engineering

Diphenyl oxide is also widely used in producing deodorant, preservative, defoaming agent and herbicide.
