GENERAL DESCRIPTION & APPLICATIONS
Benzophenone, an aromatic ketones (diphenyl ketone), is an important compound in organic photochemistry and perfumery as well as in organic synthesis. It is a white crystalline substance with rose-like odor; insolube in water; melting point 49 C; boiling point 305 - 306 C. Benzophenone is used as a constituent of synthetic perfumes and as a starting material for the manufacture of dyes, pesticides and drugs (especially anxiolytic and hypnotic drugs). Benzophenone is used as a photoinitiator of UV-curing applications in inks, adhesive and coatings, optical fiber as well as in printed circuit boards. Photoinitiators are compounds that break down into free radicals upon exposure to ultraviolet radiation. Photoinitiators undergo a unimolecular bond cleavage upon irradiation to yield free radicals (benzoin esters; benzil ketals; alpha-dialkoxy acetophenones; alpha-hydroxy alkylphenones; alpha-amino alkylphosphine; acylphosphine oxides). Another type of photoinitiators undergo a bimolecular reaction where the excited state of the photoinitiator interacts with a second molecule (a coinitiator) to generate free radicals (benzophenones, amines; thioxanthones, titanocenes). Ultraviolet radiation has more energy than visible light, and thus degrade the physical properties such as the appearance of organic substances and plastics. Benzophenones can act as optical filters or deactivate substrate molecules that have been excited by light for the protection polymers and organic substances. They, cosmetic grades, are used as sunscreen agents to reduce skin damage by blocking UV-A, B.
