Abstract
- The conversion of lignocellulose into a value-added chemical with high selectivity is of great significance but is a big challenge due to the structural diversities of biomass components. Here, we have reported an efficient approach for the one-step conversion of raw lignocellulose into diethyl maleate by the polyoxometalate ionic liquid [BSmim]CuPW<subscript>12</subscript>O<subscript>40</subscript> in ethanol under mild conditions. The results reveal that all of the fractions in biomass, i.e., cellulose, lignin and hemicellulose, were simultaneously converted into diethyl maleate (DEM), achieving a 329.6 mg g<superscript>−1</superscript> yield and 70.3% selectivity from corn stalk. Importantly, the performance of the ionic liquid catalyst [BSmim]CuPW<subscript>12</subscript>O<subscript>40</subscript> was nearly twice that of CuHPW<subscript>12</subscript>O<subscript>40</subscript>, which can be attributed to the lower incorporation of the Cu<superscript>2+</superscript> site in [BSmim]CuPW<subscript>12</subscript>O<subscript>40</subscript>. Hence, this process opens a promising route for producing bio-based bulk chemicals from raw lignocellulose without any pretreatment. [ABSTRACT FROM AUTHOR]
