How is the interfacial tension of liquid-liquid system measured by pendant drop method?

It is known that the surface/interfacial tension tension can be measured by pendant drop method and the following equation: IFT=deltaro*g*de^2/H. 1/H is function of ds/de (1/H=f(ds/de)). I used...

Why do the strange behaviour exist at the interface of tetrahydrofuran/2-propanol mixture?

I have modeled the surface tension of tetrahydrofuran (THF)/2-propanol mixture at T=288.15 K (xTHF=0.55) by using gradient theory. I take tetrahydrofuran (THF) as a reference fluid. The density...

Why does the interfacial tension of systems containing water/immiscible liquid (for example water/octane) increase by increasing the pressure?

The interfacial tension usually decreases by increasing pressure, but for water/immiscible liquid interfacial tension increases by increasing pressure.

Sorry, I have not studied in this regard, thank you!

May be using the Hard Sphere Attractive (HSA) EoS and the Semi empirical EoS (SES).

Héctor Quinteros-Lama

PC-SAFT is a good option, SAFT-VR too. You must have good results for normal compounds with both but you need to have into account that every SAFT EOS have problems with some species like carboxylic acids.

PS: use the polar and quadrupolar contributions for the EoS

Josef Chmelar

Hello

The PC-SAFT calculations in general strongly depend on the parameterization. If you optimized some of the parameters (e.g., kij or those of the polar term) based on liquid data, you can get less accurate results for the vapour phase.
