A. Ramani et al., SELECTIVE OXIDATION OF PHENOLS TO QUINONES WITH HYDROPEROXIDES CATALYZED BY CHROMIUM SILICALITE-2, Journal of chemical research. Synopses, (10), 1996, pp. 474-475
A chromium-containing medium-pore molecular sieve (Si/Cr>140) having M
EL (CrS-2) topology catalyses selectively the oxidation of various phe
nols to the corresponding p-quinones with 30% H2O2 or 70% tert-butyl h
ydroperoxide (TBHP) as the oxidant.
