A one-step direct alkylation method for synthesizing Bu levulinate from Bu alc. and furfuryl alc. has been explored. This process is carried out under reflux, at ∼ 120 °C for 2 h and utilizes a catalyst. Catalysts are based on phosphotungstic acid; the catalysts are modified via cation exchange, producing several cesium, copper and silver based phosphotungstates. Of these, the greatest activity and selectivity towards Bu levulinate was achieved over the Cu0.5H2[PW12O40] catalyst, with 100% conversion and a Bu levulinate selectivity of 69%. Various side reactions are also observed, with products that may also be suitable for biofuel applications. A detailed product anal. has been performed, and likely reaction schemes for these products have been determined Overall, these results demonstrate an efficient method for Bu levulinate production from biomass-derived sources.
