Our catalyst possessed Bronsted acidity (3 mmol/g) with an excellent stability up to 220 degrees C. XPS, FT-IR and Pyridine-IR along with microanalysis studies confirmed the presence of terminal -SO3H functional groups responsible for Bronsted acidity in the catalyst. The catalyst was found to efficiently catalyze the alcoholysis of furfuryl alcohol to give alkyl levulinates under mild reaction conditions. The complete conversion of furfuryl alcohol with 96 % and 97 % selectivities to ethyl and butyl levulinates could be achieved using ethanol and butanol, respectively. Detailed study on effect of various reaction parameters like catalyst loading, reaction time and reaction temperature on conversion and product distribution was also carried out for the ethanolysis of furfuryl alcohol to ethyl levulinate. The catalyst could be easily recovered and recycled for five times successfully, with no loss in its original activity.10aBiomass10aethyl levulinate10aFuel additive10aFurfuryl alcohol10aheterogeneous catalysis1 aPatil, Chetana, R.1 aKamble, Sanjay, P.1 aRode, Chandrashekhar, V.  uhttps://library.ncl.res.in/content/single-pot-alcoholysis-furfuryl-alcohol-alkyl-levulinates-using-heterogenized-p-tsa-catalyst
