Description and Uses
Biphenyl is an organic compound with chemical formula of C12H10. It is a white crystalline powder, insoluble in water, soluble in ether, ethanol, carbon tetrachloride, dioxane, aromatic hydrocarbons, etc. it is mainly used as solvent, heat transfer agent, fruit mildew inhibitor and organic synthesis.
Biphenyl is used as an antifungal agent to preserve citrus fruit, in citrus wrappers to retard mold growth, in heat transfer fluids, in dye carriers for textiles and copying paper, as a solvent in pharmaceutical production, in optical brighteners, and as an intermediate for the production of a wide range of organic compounds.
