Characterizing Reaction Space in the Continuous‐Flow Esterification of Oleic Acid Using a Sulfonated Hydrothermal Carbon Catalyst
Abstract: Continuous‐flow catalytic esterification of free fatty acids (FFA) with methanol in the presence of sulfonated hydrothermal carbon (SHTC) as catalyst was studied. Using a Box‐Behnken experimental design protocol, the effects of residence time, methanol:acid molar ratio, and water concentration on the conversion of oleic acid into methyl oleate were investigated. The optimum conditions for achieving esterification greater than 90 % at 100 °C were determined to be 11‐minute residence time, a MeOH:FFA molar ratio >14.6 and up to 14.9 % water. The SHTC was used continuously for 4.5 days without a significant decrease in catalytic performance. The results confirmed that SHTC is an effective solid acid catalyst in a continuous flow system for the esterification of FFA.
