Melfi, Diego Trevisan published the artcileSupercritical CO2 as solvent for fatty acids esterification with ethanol catalyzed by Amberlyst-15, Recommanded Product: Ethyl 4-oxopentanoate, the main research area is carbon dioxide Amberlyst esterification catalyst fatty acid ethanol.
This work reports on the esterification of fatty acids with ethanol using Amberlyst-15 in a scCO2-assisted system. A factorial design was carried out for the following process variables: temperature (70°C-110°C), ethanol to acid molar ratio (3:1 to 9:1) and catalyst to acid concentration (5-20 wt%), with a fixed amount of CO2 added to the reactor (28.62 g). The best reaction condition led to an 87% conversion at 110°C, 9:1, and 20 wt% in 15 min of reaction time. An exploratory kinetic study illustrates the effect of catalyst amount and molar ratio in isothermal kinetic curves. Also, a catalyst reuse study was performed. Addnl., different carboxylic acids and methanol, instead of ethanol, were evaluated as reagents. At all proposed systems, the addition of scCO2 increased the reaction conversion.
