Recently, there have been reports in the literature on sulfonated carbon catalysts prepared from sugars exhibiting interesting acid catalytic properties. However, to date, little has been reported about their activation/deactivation characteristics. For this paper, the activation/deactivation behaviors of such sulfonated carbon catalysts were investigated through the esterification of free fatty acids...
This paper reports on an investigation into the impact of carboxylic acid chain length on the kinetics of liquid-phase acid-catalyzed esterification. Using sulfuric acid and a commercial Nafion/silica composite solid acid catalyst (SAC-13), initial kinetics were measured for the reactions of a series of linear chain carboxylic acids (acetic, propionic, butyric, hexanoic, and caprylic acid) with methanol...
