Synthesis

4,4'-Dihydroxybenzophenone is prepared by the rearrangement of p-hydroxyphenylbenzoate:

HOC6H4CO2C6H5 → (HOC6H4)2CO

Alternatively, p-hydroxybenzoic acid can be converted to p-acetoxybenzoyl chloride. This acid chloride reacts with phenol to give, after deacetylation, 4,4'-dihydroxybenzophenone.

Uses

The main application of 4,4'-dihydroxybenzophenone is as a UV light stabilizer. It and its derivatives are found in cosmetics, plastics, films, adhesives and coatings, optical fiber, and printed circuit boards. It is the precursor to certain polycarbonate polymers.
