General description
Application
- A polymerization initiator in the synthesis of polyacrylamide via radical polymerization of acrylamide.
- An oxidizing agent in the photochemical oxidation of atrazine aqueous solution.
K2S2O8 can also be used in the following process:
- K2S2O8-AgSCF3 catalytic system is used in the direct trifluoromethylthiolation of unactivated C(sp3)-H bonds under mild conditions. Usage of K2S2O8 in this process plays an important role in the activation of the C-H bond and the oxidation of AgSCF3.
- K2S2O8-FeCl3 is used for the thiocyanation of 2H-indazoles using ammonium thiocyanate as a thiocyanating agent.
