Ionic liquids, due to their unique properties, offer an advantage to develop such methods under milder conditions. Herein, we show use of -SO3H functionalized imidazolium based various recyclable Bronsted acidic ionic liquids (BAILs) in catalytic quantity under ambient pressure at 120 degrees C for depolymerization of lignin (60 000 g mol(-1)) into THF soluble products with high efficiency (78% yield, 95% +/- 5% mass balance). The decoding of this efficiency by 1D and 2D (HSQC/NOSEY) NMR, FT-IR and RAMAN studies exemplify that the -OH group(s) interact with the electron deficient BAIL cation. The mechanistic insights unraveled in this study open a plethora of opportunities to design catalysts for developing efficient processes.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">14</style></issue><custom3><style face="normal" font="default" size="100%">&lt;p&gt;Foreign&lt;/p&gt;</style></custom3><custom4><style face="normal" font="default" size="100%">8.506</style></custom4></record></records></xml>
