Abstract
Several metal catalysts were examined for their effectiveness in activating hydrogen peroxide and oxygen as oxidants for conversion of lignin models t o benzoquinones. Good yields of quinones were observed when certain heterop olymetallates were used as catalysts in the presence of hydrogen peroxide. Oxygen was generally less effective. Oxidation of lignin samples gave 2-3 w t% yields of 2,6-dimethoxybenzoquinone.
