I am trying to define ionic liquid in Aspen Plus. The thermodynamic models built in Aspen are CPIG for ideal gas heat capacity, PLXANT for liquid vapor pressure  and DHVLWT for heat of vaporization. I am not able to find the constants for PLXANT (which makes use of extended antonine equation) and DHVLWT (which makes use of watson's equation). Please,help.

of course you need some data (or the ability to estimate values)

I have not access to Aspen (I have Prode Properties) but most simulators include procedures for data regression and that shouldn't be a problem,

however you may need to enter additional parameters for selected model (Pitzer, E-NRTL etc.)
