1-(2-Hydroxyethyl)-3-methylimidazolium tetrafluoroborate ([HYDEMIM] [BF4]) ionic liquid was characterised by infrared spectroscopy, nuclear magnetic resonance, ultraviolet-visible spectra and thermogravimetric analysis. Mutual mass fraction solubilities of the 12 selected solvents (ethanol, 1- propanol, 1- butanol, benzene, toluene, o-xylene, m-xylene, p-xylene, ethylbenzene, dichloromethane, chloroform and carbon tetrachloride) and [HYDEMIM][BF4] in the temperature range from 283.16 to 353.61 K were measured using a cloud-point method. Measured solubility value S was correlated as a function of temperature by a second-order polynomial.
