ABSTRACT
Binary liquid liquid equilibria for 10 systems containing an ionic liquid with thiophene were measured by dynamic method in the temperature range from 283 K to the boiling point of thiophene. The influence of ionic liquid structure on solubility of thiophene is discussed in comparison with results taken from the literature. The solubility of thiophene in all investigated ionic liquids is high - below 0.31 ionic liquid mole fraction.
