Calorimetric Experiment

A calorimetric experiment was performed to determine empirically the dependence of the specific heat of ice with salinity 0-10‰ over the temperature range from –23° C to the melting point The experimental results agree with the theoretical model determined by Schwerdtfeger (1963) for calculating the specific heat except within several degrees of the melting point and for very pure ice.

To well know the properties of ionic liquid mixtures, the viscosity of the binary mixtures containing the methylbenzene and imidazole ionic liquids (1-butyl-3-methylimidazolium tetrafluoroborate [Bmim][BF4] or 1-butyl-3-methylimidazolium hexafluorophosphate [Bmim][PF6]) were measured. Within the temperature range from 298.15 K to 308.15 K, the viscosity of the four binary systems decreased sharply as the increase of temperature. The viscosity decreased slowly in the temperature range from 308.15 K to 338.15 K. The viscosity also decreased with decreasing of the mole fraction of ionic liquid. The viscosity of methylbenzene in the imidazole ionic liquids was in sequence: [Bmim][BF4] < [Bmim][PF6]. The experimental viscosity values had been correlated using the binary parameters of Vogel-Fulcher-Tamman equation.

The viscosity of dimethylbenzene and imidazole ionic liquids (1-butyl-3-methylimidazolium tetrafluoroborate [Bmi [BF4] and 1-butyl-3-methylimidazolium hexafluorophosphate [Bmi [PF6]) was measured. Within the temperature range from 298.15 K to 308.15 K, the viscosity of the four binary systems decreased sharply as the raise of temperature. The viscosity values decrease slowly in the temperature range from 308.15 K to 338.15 K. The viscosity of dimethylbenzene in the ionic liquids was in sequence: [Bmi [BF4] < [Bmi [PF6].
