Where can I find NRTL binary interaction parameters (g_12, g_21), for 'tetrahydrofuran (THF) + acetic acid' & 'THF + trichloroethylene', except Aspen?

26 October 2024 0 2K Report

I require the binary interaction parameters (BIPs) (g_12, g_21) of the NRTL activity coefficient model. I have been provided with the experimental data of mole fractions (x1, x2), temperature (T_exp), and total pressure. Should I estimate the values of tau_12 and g_12 by regressing the activity coefficient formula, or is it more practical to obtain them from a reliable source, such as a literature review or a software package?
