Urgently asking: What physical property methods can be used for mixtures of methanol, methyl acetal, and water?
Thread Content
Since I don’t have a background in chemical engineering, my knowledge of the fundamental concepts is extremely limited; I’m working hard to learn more*. Right now, I urgently need to determine the thermodynamic properties of mixtures of methanol, methyl acetal, and water, but I’m not sure which thermodynamic method to use. I’ve tried Wilson and NRTL-HOC before, but the results were somewhat strange, so I think those methods aren’t suitable. I would like to ask experts: which method would be the best choice?

The NRTL-RK model, I guess
I previously calculated it using ProII, with the NRTL method; I’m not sure what’s strange about your results. You might as well share them so everyone can take a look and help you out
NRTL should work; give it a try
This system is available in Aspen; it uses the SysPOK model, which is based on the Unifac model. It doesn’t seem to be available in Pro/2, but you can try using Unifac
