In this study, an efficient catalytic system has been developed for the single step conversion of microcrystalline cellulose into 5-hydroxymethyl furfural and levulinic acid using Br?nsted acidic ionic liquid (IL) catalysts which have large conjugated structure. The IL catalysts used in this study comprising of different anions ([CF3SO3]?, [HSO4]?, [CF3COO]?, and [Cl]?) with a common cation 1-butyl sulfonic acid-2-phenylimidazolinium ([2-PhIm-SO3H]+), were synthesized in laboratory and characterized. The MCC conversion was carried out in a biphasic reaction medium and yields of 70 % for 5-HMF and 23 % for LA were achieved at 150 °C and 5 h reaction time. Furthermore, density functional theory (DFT) was performed to identify the key interactions in the stable configurations of the ion-pairs of ILs. The electronic properties and chemical reactivity of the individual ions and ion-pairs of ILs were investigated by performing natural bond orbital (NBO) and second order perturbation theory analysis.
