This functionality is now implemented. Binary systems are shown with the Modified UNIFAC model for the liquid phase and Peng-Robinson for the vapor phase, [here](https://thermo.readthedocs.io/Examples/Creating%20Txy%2C%20Pxy%2C%20and%20xy%20diagrams%20for%20the%20binary%20water%20ethanol%20system%20with%20Modified%20UNIFAC%20%28Dortmund%29.html).

Hello Alex, Thank you for finding this bug. For a chemical instance to be created, the structure and a valid CAS number need to have been recorded in PubChem in...

Hello Alex, I am glad you are finding useful pieces in and among the library. I intend to do a much more thorough job with the chemical metadata database this...

Hello Alex, The new syntax is available in the new version released to pypi, although it is not documented yet. I need to redo the introduction documenting Chemical. calc_H is...

Hi Marco, It sounds like it would be simpler to use the methods in thermo.viscosity directly without the mixture interface. If you know the pure component viscosities, I recommend Brokaw...

Hi Alex (and anyone else reading this): The GibbsExcessLiquid class has a few kinks to work out and feature to implement; it is for this reason I didn't create an...

Hello Dr. Olver, Thank you for the kind reply. I would be very appreciative of the feature. Please don't reprioritize this on my behalf though! ApproxFun is an incredibly large...

Hi Ben, The whole HeatCapacityLiquid isn't a good choice for a pure component above the critical point. I don't recommend you use it. I am happy with the current extrapolation...

I use pint in: [fluids](https://github.com/CalebBell/fluids/), a library for practical fluid dynamics calculations [ht](https://github.com/CalebBell/ht/), a library for practical heat transfer calculations [chemicals](https://github.com/CalebBell/chemicals/), a library for chemical property calculations and lookups [thermo](https://github.com/CalebBell/thermo/),...

@salazardetroya This is definitely a huge problem! In chemical engineering we have the quantities mole fraction, mass fraction, volume fractions; in the literature it is even common for the type...
