| 概要 |
Oxidative esterification of lower alcohols was tested over the single-phase catalysts of the Sb-Mo-O system, which was known as Sb4Mo10O31 (X phase), Sb2Mo10O31 (Y phase) and Sb2MoO6 (Z phase). In the... case of ethanol, X phase and Y phase gave stable activity compared to the Sb2O4-MoO3 mixed oxide catalyst, where Y phase gave higher yield of ethyl acetate but X phase gave acetaldehyde mainly. In comparison with oxidative esterification of a series of alcohols of C1-C4, it is concluded that the Sb-Mo-O catalyst is effective only in ethanol oxidation. The reduction experiment of the catalyst suggested that lattice oxygen was used in the stage of ethanol oxidation to acetaldehyde rather than the adsorbed oxygen.続きを見る
