How it is made

Benzophenone is usually produced by atmospheric oxidation of diphenylmethane in the presence of metal catalysts such as copper naphthenate. Other processes include Friedel-Crafts acylation of benzene with benzoyl chloride or of benzene with phosgene.

Prepared by the Friedel-Crafts ketone synthesis from benzene and benzoyl chloride in the presence of AlCl3 ... By decarboxylation of o-benzoylbenzoic acid in the presence of copper catalyst.
