Application

Potassium ethyl xanthogenate (ethyl potassium xanthogenate) has been used:
  • in synthesis of unsymmetrical sulfides via cross-coupling reaction, using recyclable CuO nanoparticles under ligand-free conditions
  • as surfactant to investigate the adsorption of colloidal dye Disperse Blue 3 onto pretreated polyester fabric
  • in determination of microgram amounts of cadmium in water samples by substoichiometric radiochemical method
