Chemical Properties
white to light yellow crystal powder
Uses
4,4'-Dimethoxybenzophenone is used in the organic synthesis. It also acts as a pharmaceutical intermediate. It is an important raw material and intermediate used in Organic Synthesis, Pharmaceuticals, Agrochemicals and Dyestuff.
Preparation
btained by photocatalytic oxidation of 4,4–′-dimethoxybenzhydrol (m.p. 69–71°) catalyzed by H3PW12O40/SiO2 in acetonitrile under oxygen atmosphere at r.t. for 1 h (90%).
General Description
Photoreactivity of 4,4′-dimethoxybenzophenone with 2-aminobenzimidazole has been examined. It is an ultraviolet absorbing additive in plastic products.
Purification Methods
Crystallise the ketone from absolute EtOH, aqueous EtOH or EtOH/AcOH. The 2,4-dinitrophenylhydrazone has m 199-200o. [Beilstein 8 H 317, 8 I 641, 8 II 355, 8 III 2649, 8 IV 2453.]
