Application

Polyethylene glycol 200 can be used as:
  • A structure-directing agent to synthesize iron vanadate (FeVO4) nanoparticles via co-precipitation method.
  • An organic additive to prepare crystalline nanorods of calcium tungstate (CaWO4) using calcium chloride and sodium tungstate via solvothermal process.
  • A surface modifier in the synthesis of calcium peroxide nanoparticles using CaCl2 as a precursor via hydrolysis-precipitation method.
  • A green solvent in combination with H2O in the preparation of 4-sulfanylcoumarins by sulfanylation of 4-tosyloxycoumarins with thiourea and alkyl halides.
