On the vapor pressure data for different NaCl dilutions at different temperatures

 The data presented in this post were extracted from the International Critical Tables.

As is usual in evaporation operations the boiling temperature elevation (BPE) is a key data for engineering calculations. Then, the vapor pressure for different combinations of solute concentration and temperatures are to be combined with the Duhring approximation (Duhring's lines).

The data was just rewritten from the source previously mentioned.
