I want to correlate some experimental data by universal quasi chemical activity coefficient (UNIQUAC) model and I need UNIQUAC parameters r and q for 2-ethylthiophene. Can anybody help me to find out these values? Thanks in advanced.
Did you search in App. of Phase Equilibria by Walas? Or may be you can generate directly in Aspen Plus. You can use generate facility???

if you want obtined adsorbtion data, you can apply the langmuir and Freundlich equation.
Thank you all for the information and opinions!
Mr. paraj, I read the paper. It was so useful. Thank you so much!
Mr. Taleb, thx. I had already checked out the book of phase equilibria in chemical engineering by Walas and also tried Aspen plus, but unfortunately none of them help.
I calculated the corresponding values as below
rthiophene=2.8569 , rCH3=0.9011 , rCH2=0.6744 r2-ethylthiophene=sum(ri)=4.4324
qthiophene=2.14 , qCH3=0.848 , qCH2=0.540 q2-ethylthiophene=sum(qi)=3.528
I got these numbers for UNIQUAC from Aspen V8.6 data bank (APV86.PURE32) :
(GMUQQ = q = 3.248) molecular area parameter for UNIQUAC activity coefficient model
(GMUQR = r = 4.24984) molecular volume parameter for UNIQUAC activity coefficient model,
Hi,
I have the values for 2-methylthiopene as follows:
r = 1.06 and q = 1.6282
Hi,
I want to find the UNIQUAC interaction parameter of ethanol-water mixture as a function of temperature
