Hydroquinone oxidation with V2O5/NaClO3/H2SO4
Hey guys!
I need help with the oxidation of hydroquinone to p-benzoquinone. I understand that V2O5 is the one that oxidizes the hydroquinone and it is also the
catalyst. The NaClO3 is then in charge of regenerating the catalizer. But I really can't write down the reaction of every step, I mean, the reaction
for the regeneration of the catalyst and the reaction for the oxidation of the hydroquinone.
I found an article with the catalytic cycle of the V2O5 (as oxidizing agent of alcohols, ketones, aldehydes) and it says that Vanadium goes from 5+ to
4+ in the oxidation state. But in this paper they didn't use other oxidizing agent.
Can you help me please?

you try:30%HNO3+V2O5(catalytic amount),note:30%HNO3 in reflux slowly dropped, then reflux for 24 hour.
