Mechanism of Ru (III) Catalysis in Oxidation of Acrylic Acid by Ceric Sulphate

Abstract

The kinetics of oxidation of acrylic acid by ceric sulphate in the presence of ruthenium (III) chloride as catalyst were studied by following the rate of disappearance of Ce (IV). The reaction order was zero with respect to Ce (IV) and unity with respect to both Ru (III) and acrylic acid. Negative effect of H⁺ and inverse first order Cl^– was observed while negligible effect of ionic strength variation and bisulphate was observed, carbon dioxide was detected as end product.
