摘要

Abstract

Combining Peng-Robinson (PR) equation of state (EoS) with an association model derived from shield-sticky method (SSM) by Liu

et al

a new cubic-plus-association (CPA) EoS is proposed to describe the thermodynamic properties of pure ionic liquids (ILs) and their mixtures. The new molecular parameters for 25 ILs are obtained by fitting the experimental density data over a wide temperature and pressure range

and the overall average deviation is 0.22%. The model parameter

for homologous ILs shows a good linear relationship with their molecular mass

so the number of model parameters is reduced effectively. Using one temperature-independent binary adjustable parameter

satisfactory correlations of vapor-liquid equilibria (VLE) for binary mixtures of ILs + non-associating solvents and + associating solvents are obtained with the overall average deviation of vapor pressure 2.91% and 7.01%

respectively. In addition

VLE results for ILs + non-associating mixtures from CPA

lattice-fluid (LF) and square-well chain fluids with variable range (SWCF-VR) EoSs are compared.
