【 摘 要 】

Ionic liquids (ILs) are salts which are liquid at low temperatures, typically with melting points under 100 ºC. In recent years, the properties of many ILs have been extensively studied and have been considered as green solvents capable of replacing traditional organic solvents. Herein, ILs derived from triazole have been synthesized, thus solubility in different solvents increases with the dielectric constant of the considered solvents. Three novel 1,2,3-triazolium-based were used for the pretreatment of sugarcane bagasse. The effect of this pretreatment on lignocellulosic biomass was analyzed by scanning electron microscopy, showing an increase in the exposure surface of the bagasse samples as structural changes in the fiber.
