Benzophenone is the organic compound with the formula (C6H5)2CO, generally abbreviated Ph2CO.
Benzophenone is a white solid that is soluble in organic solvents.
Benzophenone is a widely used building block in organic chemistry, being the parent diarylketone.
Uses:
Benzophenone can be used as a photo initiator in UV(Ultra-violet)-curing applications such as inks, imaging, and clear coatings in the printing industry.
Benzophenone prevents ultraviolet (UV) light from damaging scents and colors in products such as perfumes and soaps.
Benzophenone can also be added to plastic packaging as a UV blocker to prevent photo-degradation of the packaging polymers or its contents.
Its use allows manufacturers to package the product in clear glass or plastic (such as a PETE water bottle).
Without it, opaque or dark packaging would be required.
In biological applications, benzophenones have been used extensively as photophysical probes to identify and map peptide–protein interactions.
Benzophenone is used as an additive in flavorings or perfumes for "sweet-woody-geranium-like notes."
Synthesis
Benzophenone is produced by the copper-catalyzed oxidation of diphenylmethane with air.
A laboratory route involves the reaction of benzene with carbon tetrachloride followed by hydrolysis of the resulting diphenyldichloromethane.
Benzophenone can also be prepared by Friedel–Crafts acylation of benzene with benzoyl chloride in the presence of a Lewis acid (e.g. aluminium chloride) catalyst: since benzoyl chloride can itself be produced by the reaction of benzene with phosgene the first synthesis proceeded directly from those materials.
Another route of synthesis is through a palladium(II)/oxometalate catalyst.
This converts an alcohol to a ketone with two groups on each side.
Another, less well-known reaction to produce benzophenone is the pyrolysis of anhydrous calcium benzoate.
Organic chemistry
Benzophenone is a common photosensitizer in photochemistry.
Benzophenone crosses from the S1 state into the triplet state with nearly 100% yield.
The resulting diradical will abstract a hydrogen atom from a suitable hydrogen donor to form a ketyl radical.
Benzophenone radical anion
Alkali metals reduce benzophenone to the deeply blue colored radical anion, diphenylketyl:
M + Ph2CO → M+Ph2CO•−
Generally sodium is used as the alkali metal.
Although inferior in terms of safety and effectiveness relative to molecular sieves, this ketyl is used in the purification of organic solvents, particularly ethers, because Benzophenone reacts with water and oxygen to give non-volatile products.
The ketyl is soluble in the organic solvent being dried, so Benzophenone accelerates the reaction of the sodium with water and oxygen.
In comparison, sodium is insoluble, and its heterogeneous reaction is much slower.
When excess alkali metal is present a second reduction may occur, resulting in a color transformation from deep blue to purple:
M + M+Ph2CO•− → (M+)2(Ph2CO)2−
Commercially significant derivatives and analogues

Indicator
Benzophenone is widely used in the synthesis experiment as an indicator, it can be used as a indicator while handling toluene, benzene, THF, acetonitrile ect.; if there is a beautiful blue after added, it can be distillated and used, it is the best to kept in sodium, but the reason of generating blue is still a puzzle.
Here is the reason from a foreign book about reactions mechanism : 'a radical anion generated by the one called carbonyl radical, benzophenone acts as the indicator is that benzophenone oxygen atoms in sodium capture electrons to generate dark blue carbonyl radical; the radicals perspective on the electrical aspect is stable, mainly used to indicate 'anaerobic conditions',Widely used.
After the addition of benzophenone, more blue of the solution, indicating less oxygen in the solution, indirectly instructing the little water.
However, whether the solution turns blue, is related to the added amount of benzophenone and processing solvent, THF (300ml) contains lots of water, and needs more than about 6 hours to reflux, and of course, it is related to the amount of processing solvent, the more the longer, toluene , benzene and other samples containing less aqueous need less reflux time, it is best to add the common desiccants to pretreat, such as: potassium carbonate, sodium sulfate, sodium hydroxide, etc., so that the processing time will be shortened.

This allows manufacturers to package the product in clear glass or plastic.
Without it, opaque or dark packaging would be used.
In laboratories, solvents are often distilled with sodium and benzophenone as desicants.
The product of these two chemicals in the absence of air and water is a dark blue ketyl; a solution of this ketyl can be used to qualitatively test for the absence of air and water.
Synthesis
Benzophenone can be prepared by the reaction of benzene with carbon tetrachloride followed by hydrolysis of the resulting diphenyldichloromethane, or by Friedel-Crafts acylation of benzene with benzoyl chloride in the presence of a Lewis acid (e.g. aluminum chloride) catalyst.
Chemistry
Benzophenone is a common photosensitizer in photochemistry.
Benzophenone crosses from the S1 state into the triplet state with nearly 100 % yield.
The resulting diradical will abstract a hydrogen atom from a suitable hydrogen donor to form a ketyl radical.
Benzophenone radical anion
Sodium is commonly used as a desiccant to purify solvents by reacting with water to give the hydroxide, which is nonvolatile:
Na + H2O → NaOH + 1/2 H2
The main problem with the use of sodium as a desiccant (below its melting point) is associated with the slow rate of reaction between a solid and a solution.
When however, the desiccant is soluble, the speed of drying is much higher.
Benzophenone is often used to generate such a soluble drying agent.
An advantage to this application is the intense blue color of the ketyl radical anion.
Thus, sodium/benzophenone can be used as an indicator of air-free and moisture-free conditions in the purification of solvents by distillation.
Benzophenone is the organic compound with the formula (C6H5)2CO, generally abbreviated Ph2CO. Substituted benzophenones such as oxybenzone and dioxybenzone are used in sunscreen.
