碳水化合物仅在普通有机溶剂和弱配位离子液体中少量溶解，如[BMIm][BF4]。相比之下，含有二氰酰胺阴离子的离子液体溶解率约为。200g L-1葡萄糖，蔗糖，乳糖和环糊精。在[BMIm][dca]中，南极念珠菌脂肪酶B介导蔗糖与十二烷酸的酯化反应。
Carbohydrates are only sparingly soluble in common organic solvents as well as in weakly coordinating ionic liquids, such as [BMIm][BF4]. Ionic liquids that contain the dicyanamide anion, in contrast, dissolve approx. 200 g L-1 of glucose, sucrose, lactose and cyclodextrin. Candida antarctica lipase B mediated the esterification of sucrose with dodecanoic acid in [BMIm][dca].
