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.
2-Amino-5-chlorobenzophenone is used as an intermediate to produce pharmaceuticals especially for a class benzodiazepines (anxiolytics and hypnotics) such as alprazolam, chlordiazepoxide and diazepam. |
