Abstract
The ketonization of hexanoic acid, which can be prepared by the fermentation of sugars, was performedin an effort to obtain the diesel-blendable high-carbon-number ketone 6-undecanone in this study. Basedon observations of the leaching of highly active base catalysts, magnesium oxide and manganese oxide,the stable amphoteric solid catalyst zirconia was selected for the acid-rich reaction environment. A high-surface-area zirconia aerogel was prepared, which successfully ketonized hexanoic acid to 6-undecanonewith high conversion, 72.3%, and high selectivity, 92.6%. The further optimization of the porous structuresof zirconia led to possibly improved mass transfer with approximately 35 nm of pores, which improvedthe catalytic activity of zirconia.
