Treatment efficiencies of five ionic liquids are studied.
ILs with β > 0.72 resulted >55% glucose yield after 24 h.
Viscosity and surface tension of ILs have a negative correlation with glucose yields.
[C2mim][OAc] with high β, smaller anion and shorter alkyl chain gave highest glucose yields with maximum reduction in CrI.
[C4mim][BF4] was not at all effective in improving the glucose yields.
