Vanadium-substituted Keggin heteropolycompounds as catalysts for ecofriendly liquid phase oxidation of 2,6-dimethylphenol to 2,6-dimethyl-1,4- benzoquinone
(Elsevier Science, 2004-08)
Molybdovanadophosphate heteropolycompounds, H4PMo 11VO40 and H9PMo6V6O 40 and the corresponding Cs salts, were synthesized. The influence of thermal treatment on their Keggin primary structures and their acidic properties ...
Keggin heteropolycompounds as catalysts for liquid-phase oxidation of sulfides to sulfoxides/sulfones by hydrogen peroxide
(Elsevier Science, 2011-03)
H4PMo11VO40, H5PMo 10V2O40 and H9PMo6V 6O40 acids and an acidic pyridinium salt of H 4PMo11VO40 were synthesized. They were characterized by FT-IR and the variations of their acid properties were determined by titration ...
