Various imidazolium-based ionic liquids (ILs), considered as “green” solvents, were used as efficient solvents for galactomannan and more specifically for guar gums of high molecular weight. FT-IR as well as the high activation energies reflect hydrogen bonds between the guar backbone and anions of ILs which act as chaotropic agents. Importantly, t...


... Ionic liquids (ILs) have recently emerged as promising media for lignocellulose treatments in biorefinery scenarios and are continuously attracting the enormous interest of the lignocellulose biomass community [20] due to their broad range of applications: fractionation and biorefinery of lignocellulosic biomass [21][22][23][24][25]; cellulose dissolution [26][27][28]; preparation of cellulose fibers, films, beads, and others [20,[29][30][31]; and, in particular, the homogeneous synthesis of polysaccharide derivatives [32][33][34][35][36][37]. The latter was employed in esterification reactions [38,39], particularly acetylation [32,[40][41][42], but also etherification reactions [43][44][45] and other conversions [20]. The homogeneous syntheses of polysaccharide derivatives facilitated by ionic liquids are fast and with a high degree of efficiency, yielding high degrees of substitution (DS) with short reaction times [20] and good control of the degree of substitution (DS) [46,47]. ...
