AbstractCarbohydrates were found to have substantial effects on tailoring phase tunable of ionic liquids (ILs) and water. Phase behaviors of 1-alkyl-3-methylimidazolium derivatives [C(n)mim]X (n = 2 to 10, X = Cl(-), Br(-), BF(4)(-))-carbohydrate-H(2)O were systemically investigated. For hydrophilic ILs, 1-alkyl-3-methylimidazolium tetrafluoroborate [C(n)mim]BF(4) (n = 3, 4), the homogeneous aqueous solution can be induced to separate two aqueous phases by addition of carbohydrate. For hydrophobic ILs, [C(n)mim]BF(4) (n = 5 to 10), the mutual solubility with water can be lowered by addition of carbohydrate. While 1-alkyl-3-methyl imidazolium chloride ([C(n)mim]Cl, n = 2 to 10) and 1-alkyl-3-methyl imidazolium bromide ([C(n)mim]Br, n = 2 to 10) aqueous solutions never form aqueous two-phase systems (ATPSs) with carbohydrate in the investigated temperatures ranging from (242.15 to 373.15) K. The high partitioning behavior of phenol in ([C(n)mim]BF(4) (n = 3 to 10) (1) + carbohydrate (2) + H(2)O (3) shows that carbohydrate-tailored {IL + H(2)O} systems are feasible to be used as extraction systems, especially in biological and environmental engineering.
