Lignin was isolated by using an ionic liquid, known as an environmentally friendly green solvent, which is effective in isolating and purifying lignin with minimal chemical transformations and high purity. Lignocellulosic biomass is one of the most important biomass resources and has been selected as alix gracilistyla Miq. with rapid growth characteristics. Salix gracilistyla Miq. samples with extractives free were pretreated by 1-ethyl-3-methylimidazolium acetate (EminAc). The solid content of wood powder was 15%, and the reaction was carried out at 80, 90, 100 and 120 ℃ for 2 hours. The amount of water soluble fraction was about 10% at the reaction temperature of 60, 80 and 90 ℃, and more than two times at 120 ℃. The yield of lignin obtained from the water soluble fraction at 120 ℃ for 2h was about 4%. The properties of IL-pretreated lignin (purity and molecular weight) were investigated by FT-IR and GPC analysis.
