一般描述

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.

应用

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).
