| Abstract: | The productive process of 2-hydroxy-4-methoxybenzophenone (UV-9) by condensation of trichloromethy benzene with resorcin to form intermediate 2, 4 - Dihydroxybenzophenone and then methoxylation the p-position by methyl- sulfat to form the target compound UV - 9 has been minutely studied. It was found that this productive process was facilitate and safe to perform, evironmental friendly and economical. |
