  • Objectives
  • 1. Continue analysis of OPD+H2O2 with Mb Citrate with H2O as a solvent
  • Procedure:
  • 1. Same protocol as 5/20 using H2O instead of MeOH


  • Data:




  • Synthesis of Na12P2W18O62:


  • Synthesis of Na12P2W18O62 is crucial for synthesizing polyoxometalates.1 We will be synthesizing POMs in the following weeks, and the preparatory reactions will be set up soon.


  • Procedure:
  • 1. 100 grams of Na2WO4*2H2O was added to 350 mL of water and boiled
  • 2. 150 mL of 85% H3PO4 was slowly added dropwise to the solution

Began dropping H3PO4 at 3:30, dropped for approximately 15 minutes

  • 3. The resulting yellow-green solution was refluxed overnight (5-13 hours indicated1).

  • 1. Finke et al, Trivalent Heteropolytungstate Derivatives, Journal of Inorganic Chemistry, 1987, 26, 3886-3896.
