خلاصه مقاله:
In this work, we apply Tao-Mason equation of state to benzene+1-butyl-3-methylimidazolium tetrafluoroborate and benzene+ 1-butyl-3-methylimidazolium hexafluorophosphate ionic liquids. Three temperature-dependent quantities are needed to use the equation of state: the second virial coefficient, B2 , effective van der Waals covolume, b, and a scaling factor, α. The second virial coefficients are calculated from a correlation that uses the normal boiling temperature and normal boiling density. α and b can also be calculated from the second virial coefficient by scaling. In thisprocedure, the number of input parameters, for calculation of B2, α a nd b r educed f rom 5 ( i.e., critical temperature, critical pressure, acetric factor, Boyle temperature TB and the Boyle volume υB ) to 2(i.e., Tbp and ρbp). A close inspection of the deviations given in this project reveals that, the TM EOS predicts the densities with a mean AAD of 2.42%.
