Decomposition of peracetic acid catalyzed by cobalt(II) and vanadium(V)
Article Abstract:
Peracetic acid (Pa) is used for wood pulp delignification and bleaching in processes entirely free of chlorine and in which metals desorb from fibers into aqueous solutions. Vanadium (V) and cobalt(II) are the most potent in decomposing Pa to O2, in a wasteful manner, of the metals involved in bleaching systems. Free radical mechanisms are in effect. Kinetic data indicate that there is in effect a free-radical decomposition mechanism already described for Co(II).

Catalysis by topologically anchored metal complexes: liquid-phase hydroxylation of benzene by H2O2 in the presence of zeolite-supported Fe(II) phthalocyanine
Article Abstract:
Activity of zeolite-supported Fe(II) phthalocyanine as a catalyst in the liquid-phase hydroxylaion of benzene by H2O2 has been studied. Phenol is the primary product of the reaction at room temperature. With refluxing the reaction goes on to products of further oxidation, p-benzoquinone and hydroquinone. Yields are low.
