In this study, production of n-butyl levulinate from furfuryl alcohol was investigated using KCC-1/Pr-SO3H as an efficient heterogeneous catalyst. The catalyst was prepared and characterized using FT-IR, N2 adsorption/desorption, scanning electron microscopy (SEM), transmission electron microscopy (TEM), pyridine-adsorbed FT-IR spectroscopy and TGA techniques. The effects of different parameters on the reaction conditions including temperature, reaction time, catalyst amount, and furfuryl alcohol volume were evaluated. The highest yield of n-butyl levulinate was 81.9% at 120 °C after 3 h. The catalyst was recovered and reused at least four times with insignificant change in yield of n-butyl levulinate.
