Abstract
Room temperature ionic liquids of 1-butyl-3-methylimidazolium tetrafluoroborate, [bmim][BF4], nitrate, [NO3]−, phosphate, [PO4]3−, and hydrogen sulfate, [HSO4]−, have been synthesized and characterized by 1H-NMR, 13C-NMR, mass spectrometry and IR spectroscopy methods. The effect of nature of inorganic anion on hygroscopic property has been studied. Physicochemical properties such as density, viscosity, melting point, freezing point, glass transition, thermal decomposition temperature and specific electrical conductivity have been determined. The influence of temperature and water concentration on density, viscosity and specific electrical conductivity values has been investigated. The dependence of physicochemical properties against anion nature and water content has been explained according to cation–anion interactions. The anomalous behaviors of density or conductivity values for equimolecular aqueous solutions of 1-butyl-3-methylimidazolium hydrogen sulfate or tetrafluoroborate ionic liquids have been found and associated with significant restructuring. The formation of crystalline hydrates of the composition of [bmim][BF4]x0.5H2O was observed.
