N2 - Levulinic acid (LA) is a valuable renewable resource that can serve as a versatile biomassderived building block for the synthesis of organic chemicals, providing a sustainable alternative to depleting fossil fuel resources. Catalytic esterification of LA with alcohol yields levulinate esters, which find numerous applications including perfumes and fuel additives. In this study, the performance of Indion 190 as a solid acid catalyst was investigated for the esterification of LA with n-butanol to produce n-butyl levulinate (BL). The effects of reaction time, catalyst loading, temperature, and molar ratio of LA to butanol were examined One Factor at a Time (OFAT) to optimize levulinic acid conversion. The highest conversion of LA, which was 92.59%, was attained with a reaction time of 6 hours at 100 ◦C, utilizing a catalyst loading of 1.25 wt% Indion 190 for a molar ratio (LA: butanol) of 1:8. In the kinetic study of the reaction, an activation energy of 65.5 kJ/mol was obtained. Indion 190 proved to be a promising, cost-effective solid acid catalyst for the production of levulinate esters, providing an eco-friendly pathway for the continuous production of butyl levulinate.
