چکیده
|
The perturbed-chain statistical associating fluid theory (PC-SAFT) is re-parameterized
for ionic liquids (ILs) by using the experimental density data over a wide range of temperature at
atmospheric pressure presented. In this work, we focused on the most frequently studied imidazolium
based ILS. The studied systems included (1-alkyl-3-methylimidazolium tetrafluoroborate
([Cnmim][BF4]), 1-alkyl-3-methylimidazolium hexafluoroborate ([Cnmim][PF6]), 1-alkyl-3-
methylimidazolium bistrifluoromethylsulfonylimide ([Cnmim][Tf2N]) and 1-alkyl-3-
methylimidazolium trifluoromethanesulfonate ([Cnmim][CF3SO3])). In all cases, good agreement with
experimental data is obtained. Then we use the optimized PC-SAFT parameters for calculating the
densities of 1-Butyl-3-methylimidazolium Tetrafluoroborate [C2mim][BF4], from 0.01 to 40 MPa and
from 293 to 323 K.
