Taketoshi, Ayako published the artcileOxidative esterification of aliphatic aldehydes and alcohols with ethanol over gold nanoparticle catalysts in batch and continuous flow reactors, COA of Formula: C9H18O2, the main research area is aliphatic aldehyde alc ethanol oxidative esterification gold nanoparticle catalyst; batch continuous flow reactor phys property.
Selective esterification of aliphatic aldehydes and alcs. with ethanol in the absence of a base is a more difficult reaction than that with methanol. Gold nanoparticles on ZnO were found to catalyze the oxidative esterification of octanal to Et octanoate with high selectivity. In addition, it was found that Au/ZnO was the most effective catalyst for yielding the desired Et ester without a base by direct esterification of 1-octanol with ethanol. As far as we know, this is the first report on oxidative esterification to give aliphatic Et esters from less reactive aliphatic alcs. and aldehydes without a base. The optimal size of gold NPs ranged from 2 to 6 nm and the presence of Au(0) was indispensable for this reaction. Au/ZnO exhibited the highest catalytic activity in both batch and flow reactors. The conversion was maintained for more than 20 h with 95% selectivity to the desired Et ester in the flow system.
