Description

General description

Benzophenone is an organic compound that can be prepared by the atmospheric oxidation of diphenyl methane with copper naphthenate catalyst. It can also be synthesized by the Friedel-Crafts acylation of benzene with benzoyl chloride.

Application

Benzophenone is mainly used as a photoinitiator molecule in a variety of 3D printing applications. It has a high quantum yield that makes it useful in the development of UV curable photopolymers.
