Perchlorate acid media parameters

Finally, there are two reports describing the oxidation of phenols. The first is from Pelizzetti et al. (1976) in which 4,4 -biphenyl diol is oxidized by Ce(IV) in perchlorate medium at reduced temperature. The product of oxidation, which proceeds at stopped-flow lifetimes, is the corresponding 4,4 -biphenoquinone. The oxidation reaction was studied under second-order conditions and indicates no acid concentration dependence with very rapid rates. The activation parameters are AH = 38 ( 13) kJmol and AS = —13 ( + 42) Imol consistent with an intramolecular rate-determining step. [Pg.360]
