利用原位粘度测量，测定了纤维素在一些离子液体中的溶解速度，从而定量地评估了它们作为溶剂的性能。结果表明，1-丁基-3-甲基咪唑乙酸酯在氯离子或二甲基磷酸酯阴离子作用下溶解纤维素的速度比类似离子液体快。对数据的分析突出了阴离子碱度和相对浓度对溶解速度的影响。
Using in situ viscosity measurement, the rate of cellulose dissolution in a number of ionic liquids has been determined allowing their performance as solvents to be quantitatively assessed. 1-Butyl-3-methylimidazolium ethanoate was shown to dissolve cellulose faster than analogous ionic liquids with chloride or dimethylphosphate anions. Analysis of the data highlights the influence of both anion basicity and relative concentration on the rate of dissolution.
