Description of biphenyloxide
- Diphenyl ether is the organic compound with the formula O(C6H5)2. The molecule is subject to reactions typical of other phenyl rings, including hydroxylation, nitration, halogenation, sulfonation, and Friedel–Crafts alkylation or acylation. This simple diaryl ether enjoys a variety of niche applications.

What is Diphenyl ether?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Diphenyl ether which has developed particularly rapidly in recent years. Do you know about Diphenyl ether?
- The official answer:Diphenyl ether is also known as phenyl ether. Colorless oily liquid or crystalline. It has a light clear aroma of geranium. Relative density 1.086, melting point 26~28℃, boiling point 259℃. Insoluble in water, inorganic acid solution, and alkali solution, soluble in ethanol, ether, benzene, and glacial acetic acid. It is produced by heating sodium or potassium phenol with chlorobenzene or bromobenzene in the presence of copper powder as a catalyst. It is chemically stable, does not change color, has a long fragrance retention time, and is widely used as an artificial fragrance fixing agent in soap fragrances.
What’s the application of Diphenyl ether?
- GB2760–1996 provides for the temporary use of edible fragrances, and GB2760-2001 provides for citrus preservatives. Uses and diphenylmethane shared, the aroma can be more light floating, can be used in soap, detergent, daily industrial products with rose, incense leaves, hyacinth, incense vetch, new marijuana, sandalwood, and other types of fragrance to give the green gas. It can also be used to formulate artificial fragrance oil. biphenyloxide is mainly used as one of the organic high-temperature heat carrier components. The mixture prepared by biphenyloxide and biphenyl according to the mass ratio of 73.5:26.5 is called Conductive A. Temperature range: 232-399℃ for gas phase, 21-399℃ for liquid phase, and the working temperature are not more than 400℃. The mixture composed of biphenyloxide and methyl biphenyl is called conductive LF, which has a low freezing point and can still be used at -30℃, and is a low temperature, low viscosity heat carrier. biphenyloxide has the aroma of geranium and begonia, also with sweet orange and narcissus fragrance, in the fragrance industry is called crystalline geranium oil or artificial geranium oil. As biphenyloxide is more stable than alkali, it is mostly used in the preparation of soap fragrance, also often used as a substitute for geranium oil, suitable for modulating floral fragrance makeup, deodorant, etc… The product is as organic synthesis intermediates, used in the fragrance industry, synthetic resins, and other organic synthesis production. Use constant temperature heat transfer medium. Gas chromatography stationary solution (maximum use temperature 100 ℃, the solvent is acetone). Organic synthesis, fragrance. 99.9% high purity grade used as plasticizer medium based on PVC film.
