ABSTRACT
The solubility of aloe-emodin in five imidazolium-based ionic liquids (ILs), 1-decyl-3-methylimidazolium chloride ([C10mim]Cl), 1-hexyl-3-methylimidazolium hexafluorophosphate ([C6mim]PF6), 1-hexyl-3-methylimidazolium tetrafluoroborate ([C6mim]BF4), 1-butyl-3-methylimidazolium tetrafluoroborate ([C4mim]BF4), and 1-butyl-3-methylimidazolium bis(methylsulfonyl)amide ([C4mim]NTF2) was measured respectively from (295.55 to 363.55) K at atmospheric pressure using a laser monitoring observation method combined with high performance liquid chromatography (HPLC). A simplified dual-parameters equation and ?h equation were used to correlate the experimental solubility data of aloe-emodin in investigated ILs and exhibited good agreement.
