摘要

Abstract

The density and viscosity of 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM

]

[BF

]

and 1-butyl-3-methylimidazolium chloride [BMIM

]

[Cl

]

and their binary mixtures within the temperatures from 303.15 K to 323.15 K and at ambient pressure were determined in this work. The temperature dependences of density and viscosity were satisfactorily described with the linear model and the Vogel-Tammann-Fulcher type equation

respectively. The molar volume and viscosity of binary IL mixtures were predicted through ideal mixing rules showing that almost null deviations for IL mixtures were observed and their mixing was remarkably close to linear ideal behavior in the molar volumes

while comparatively large errors in viscosity occurred. Additionally

the molar volume of the investigated pure ILs and their mixtures could well be predicted by a predictive model presented by Valderrama

et al
