Benzophenone is a colorless prismatic crystal with sweet taste and rose fragrance. It has a melting point of 47-49C, a relative density of 1.1146, and a refractive index of 1.6077. It is soluble in organic solvents and monomers such as ethanol, ether and chlor form, but insoluble in water. It is a free radical photoinitiator, mainly used in free radical UV curing systems, such as coatings, inks, adhesives, etc. It is also an intermediate for organic pigments and fragrances. This product is also a styrene polymerization inhibitor and a fragrance fixer, which can impart a sweet smell to the fragrance, and is widely used in perfume and soap flavors. During storage and transportation, the product should be protected from moisture, sun, and away from heat sources, and its temperature should not exceed 45C.
