Description

Description générale

Silver sulfate (Ag₂SO₄) is a disilver(I) salt of sulfuric acid. It participates in the TiO₂-assisted photooxidation of substituted benzyltrimethylsilanes in acetonitrile. Diarylethanes were obtained in 50-74% yields.

Application

Silver sulfate may be employed in the preparation of the following:

• Iodination reagent in combination with iodine for the synthesis of iododerivatives.
• Silver sulfate reagent, which is required for the determination of Chemical Oxygen Demand (COD).
