Description

General description

Silver sulfate (Ag2SO4) is the 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. It has been reported as one of the common atmospheric silver corrosion product.

Application

Silver sulfate may be employed in the following studies:
• Iodination reagent in combination with iodine for the synthesis of iododerivatives.
• Synthesis of iodinated uredines.
• Preparation of silver sulfate reagent, which is required for the determination of Chemical Oxygen Demand (COD).
