Ozone Initiated Ni/Metal Oxide Catalyzed Conversion of 1,2-Dichlorobenzene to Mucochloric Acid in Aqueous Solutions
In aqueous systems, chlorinated hydrocarbons exhibit
low chemical
reactivity and nonbiodegradability due to its toxicity. Relative efficiencies
of 1% and 5% Ni loaded on alumina, silica and titania as catalysts
for conversion of 1,2-dichlorobenzene to muchochloric acid (MCA) were
investigated at (20 ± 1) °C and ∼1 atm as function
of time. All nickel loaded metal oxides gave good conversions and
product selectivity toward MCA, with little mineralization. Ni/SiO<sub>2</sub> showed superior conversion with selectivity of 89.9–100%
toward MCA. The ozonation products were characterized by <sup>1</sup>H NMR, IR, Mass and GC-MS, while the catalyst materials were characterized
by BET, SEM, FT-IR, ICP, and XRD methods
