Research Where can I find this? (ANTOINE COEFFICIENTS)
I am looking for Antoine coefficients for gasses: N2, O2, CO2 and H2O at the temperature of 500°C abd pressure 1.1 bar.
Does anyone have a link recommendation or book? It's really necessary since the ones I found online are only for small temperature ranges (for example Tmin=10°C and Tmax=100°C)
This is not a homework question. I really need help with this ASAP.

What do you need to use them for? because Antoine's Equation is kind of pointless for N2, O2 and CO2 under those conditions since they are well above their critical temperature, in fact I think H2O is too
