Uses and synthesis of Biphenyl powder

Biphenyl powder, also known as phenylbenzene, biphenyl, is a compound formed by connecting two phenyl groups, Biphenyl CAS 92-52-4 is white or colourless to yellowish flaky crystals, and the industrial product is yellowish, with a special smell. Melting point 69.2°C, boiling point 255.2°C. Biphenyl Raw Materials is insoluble in water, but soluble in organic solvents.

Applications / Functions of Biphenyl powder

1. Biphenyl powder is the raw material of engineering plastics polysulfone, used in the production of trichlorobiphenyl, pentachlorobiphenyl, used as a heat carrier, anticorrosive agent and so on.
2. Biphenyl CAS 92-52-4 is also the intermediate of rodenticide Rodenticide and Bromacil, and it is the organic carrier with good performance.
3. Biphenyl Raw Materials have high thermal stability and low vapour pressure, and have been used as heat carriers alone or mixed with diphenyl ether for a long time.
4. 

Physicochemical Property of Biphenyl powder

White or slightly yellowish flaky crystals, with a unique aroma. Insoluble in water, acid and alkali, soluble in alcohol, ether, benzene and other organic solvents.

Production methodprocess of Biphenyl powder

In the laboratory, the aniline diazotisation, the resulting diazonium salt added to benzene, and then this mixture slowly added to sodium hydroxide solution, stirring the reaction, the temperature from below 5 ℃ slowly rise to 30-35 ℃, the reaction after 8h that is generated Biphenyl powder.

• Biphenyl CAS 92-52-4 is prepared by thermal cracking and dehydrogenation of benzene as raw material.
• Biphenyl Raw Materials is obtained by heating distillation of iodobenzene or bromobenzene and metal sodium or copper.
