Description and Uses
Benzophenone is a combustible, white,crystalline solid with a rose-like odor. Molecularweight=182.23; Specific gravity (H2O:1) = 1.085 at 50℃;Boiling point = 305℃; Freezing/Melting point = 48.5℃;Latent heat of vaporization=2.93 3 105 J/kg; Heat ofcombustion= -358 3 105 J/kg. Hazard Identification(based on NFPA-704 M Rating System): Health 1,Flammability 1, Reactivity 0. Insoluble in water.
Benzophenone is used as a synthetic intermediate for manufacture of pharmaceuticals and agricultural chemicals. It is also used as a photoinitiator in UV-curable printing inks, as a fragrance in perfumes, as a flavor enhancer in foods. Benzophenone can be added as a UV-absorbing agent to plastics, lacquers, and coatings at concentrations of 2–8%.
