In a one-pot method, Bronsted acidic ionic liquid (BAIL)-catalyzed hydrolysis of hardwood hemicellulose at 160 degrees C in water media gave C5 sugars (xylose + arabinose) in 87% yield. The efficiency of the ILs and their acid strength both followed the similar trend, [C3SO3HMIM][HSO4] &gt; [C3SO3HMIM][PTS] &gt; [C3SO3HMIM][Cl] &gt; [BMIM][Cl]. The ion-dipole-type interaction present between the BAIL and the substrate, which is proposed by the H-1 NMR study, is suggested to help in achieving better activity with BAIL than with mineral acid, H2SO4.</p>1 aMatsagar, Babasaheb, M.1 aDhepe, Paresh, Laxmikant  uhttps://library.ncl.res.in/content/bronsted-acidic-ionic-liquid-catalyzed-conversion-hemicellulose-sugars-0
