    hello,
    could somebody help me to get data with regards to the sollubility of ammonia into water (for pressures up to 40 bar and temperatures up to 150degC)
    no I am not a student, just a mechanical engineer with poor knowledge of chemistry, trying to get a better understanding of binairy thermodynamic cycles
    thanks

    All I know is that:

    47% (0 °C)
    31% (25 °C)
    28% (50 °C)

    That's at 1 atmospheric >.<.

    I have no idea where you can find the solubility of ammonia or other compounds at different temperatures and atmospheric pressures...

    This is a pretty big question really, as you've not specified a few different combinations... you want 40 bars and up to 150degC.

    Hope somebody can help you!

    You can calculate the equilibrium concentration of ammonia in water at various partial pressures and temperatures using the equations in this link.
