(a) Rapid acetylation of polysaccharides at 25°C. (b) Effect of reaction time on the DS of cellulose propionate synthesized in 1-butyl-3-methylimidazolium propionate ([Bmim][CH3CH2COO]) with a molar ratio of 3 : 1 at 80°C. (c) Effect of reaction time on the DS of cellulose benzoate synthesized in 1-butyl-3-methylimidazolium benzoate ([Bmim][PhCOO]) with a molar ratio of 3 : 1 at 80°C. (d) Effect of reaction time on the DS of cellulose cyclohexanecarboxylate synthesized in 1-butyl-3-methylimidazolium cyclohexanecarboxylate ([Bmim][ChCOO]) with a molar ratio of 3 : 1 at 80°C.
