Sodium Tungstate Catalytic Hydrogen Peroxide

Sodium tungstate catalytic hydrogen peroxide is using sodium tungstate as catalyst hydrogen peroxide reaction is a process of producing other substances. Hydrogen peroxide (H₂O₂), also known as the oxidizing agent. Studies have shown that hydrogen peroxide and sodium tungstate catalyst in the aqueous phase, it must be water-soluble peroxygen salt into the oil phase substrate sufficient contact to react. Sato used cyclohexene as raw materials, 30% H₂O₂ as oxidant, Na₂WO₄ • 2H₂O is catalyzed organic reactions.

Research indicates acidic to some extent, it can promote the formation of sodium tungstate poly acid or a salt thereof, polyphosphoric acid or a quaternary ammonium salt more effectively the transfer of oxygen to hydrogen peroxide in the reaction substrate.

With hydrogen peroxide, a phase transfer catalyst or a complexing agent, sodium tungstate as catalyst were thoroughly mixed and the mixture was warmed to 85 ~ 90 ℃, added octafluoropentanol to prepare octafluoro acid. Then, the barium carbonate powder was added to the reaction mixture to precipitate sodium tungstate, stirred, cooled, filtered to remove the precipitate.
