CoCuAl Hydrotalcite-like Compounds: Synthesis and Use in the Catalytic Oxidation of p-Cresol Ⅱ.Catalytic Oxidation of p-Cresol
Abstract:
The oxidation of p-cresol using CoCuAl hydrotalcite like compounds(HTLc) has been investigated. The calcinated HTLcs were found to have a higher activity than the uncalcinated ones, as well as the simple mixed oxides. The products from calcination at 450℃ with Co:Cu:Al=3:1:1 showed an optimum activity, giving 98.4% yield of p-hydroxy benzaldehyde. A possible mechanism has been proposed, assuming that both Co2+ and Co3+ in the catalysts with spinel structure act as an active center in the reaction.
