Novel binary eutectic mixtures based on imidazole

Three new binary eutectic mixtures have been formed between imidazole and organic salts. These binary eutectic mixtures showed the similar properties to ionic liquids, i.e. low molten point (21 °C) and viscosity (3.1 cp), high conductivity (5.2 × 10− 2 S cm− 1), and stable electrochemical window (3.4 V). Especially, these binary eutectic mixtures exhibited unusual solvent properties for a wide of solutes.
