Why is the Txy line drawn in the figure a straight line? My data is also shown in the image; please advise, experts

This is mainly to simulate the boiling point of CaCl2, using BINARY for that purpose

It seems that the LZ is calculating the TXY diagram for the CaCl2–water system, but CaCl2 is usually in a solid state; when it dissolves in water it mainly dissociates into ionic forms, and it is virtually absent in the vapor phase. And TXY is generally mainly used for vapor-liquid equilibrium. In my opinion, such a setting is unreasonable.

I see. The TXY diagram is mainly used for liquid mixtures; a calcium chloride aqueous solution does not belong to liquid mixtures. Thank you for the clarification

You’re welcome; feel free to come and discuss on Haichuan.
