Electrochemical Oxidation of Chlorinated Phenols
Electrochemical oxidation has been proposed as a remediation method for chlorinated phenols but is hampered by anode fouling. In this work we explore the mechanism of anode fouling by chlorinated phenols, compare structure vs reactivity for phenols differing in the extent of chlorination, and relate the efficiency of oxidation to the mechanism of oxidation at different electrode types. Linear s...
متن کاملPeroxide oxidation of indole to oxindole by chloroperoxidase catalysis.
In the presence of chloroperoxidase, indole was oxidized by H2O2 to give oxindole as the major product. Under most conditions oxindole was the only product formed, and under optimal conditions the conversion was quantitative. This reaction displayed maximal activity at pH 4.6, although appreciable activity was observed throughout the entire pH range investigated, namely pH 2.5-6.0. Enzyme satur...
متن کاملGeneration of Hydrogen Peroxide by Plant Peroxidases Mediated Thiol Oxidation
OBINGER C , BURNER U. & EBERMANN R. 1997. Generation of hydrogen peroxide by plant peroxidases mediated thiol oxidation. Phyton (Horn, Austria) 37 (3): (219) (226). Thiol oxidation by plant peroxidases is an oxygen consuming process independent of hydrogen peroxide addition. The in vitro system consists of two interdependent reactions, i.e. hydrogen peroxide mediated oxidation of thiols via the...
متن کاملSinglet oxygen production by chloroperoxidase-hydrogen peroxide-halide systems.
Singlet oxygen production in the chloroperoxidase-hydrogen peroxide-halide system was studied using 1268 nm chemiluminescence. With chloride or bromide ions, singlet oxygen is produced by the mechanism (formula; see text) (formula; see text) where X- is chloride or bromide ion. Under conditions where there is high enzyme activity and when Reaction B is fast relative to Reaction A, singlet oxyge...
متن کاملSelective oxidation of sulfides to sulfoxides by a vanadium-based catalyst using 30% hydrogen peroxide
The vanadium-based catalyst, acts as a homogeneous catalyst for the selective oxidation of various kinds of sulfides with 30% aqueous H2O2. Vanadium-based catalyst was successfully used as the oxygen source for the oxidation of sulfides to sulfoxides for the first time. The sulfoxides were obtained in a good way to high yields without any detectable over-oxidation to sulfones under normal condi...
