Table 1 Results from the ionic liquid synthesis

From: Evaluation of four ionic liquids for pretreatment of lignocellulosic biomass

Abbreviation Structure Name H2O cont. Cl-cont. Yielda(%)
[C4C1im][MeCO2] 1-butyl-3-methylimidazolium acetate 260 ppm 0.8% 37
[C4C1im][HSO4] 1-butyl-3-methylimidazolium hydrogen sulfate 20% N.A.b 87
[C4C1im][Cl] 1-butyl-3-methylimidazolium chloride 940 ppm N.A. 48
[C=C2C1im][MeCO2] 1-allyl-3-methylimidazolium acetate 1500 ppm 0.9% 36
  1. aThe yields were calculated for the total synthesis (two steps for all of the ILs except [C4C1im][Cl], which was synthesized in one step) starting from the substituted imidazoles. bNot Applicable.
