CCL: vapor pressure reference

Dear all,

This might a little bit off topic. But I still would give a try.

I am looking for the vapor pressure of NaCl, KCl, etc at 298.15 K. It turned out to be very difficult, due to the fact most of the experiments were performed at high temperature. I was trying to use the two fitted Equs. provided by NIST to interpolate to 298 K, but failed (two sets gave totally different numbers). I am wondering any of you happen to know a good reference book/collection have numbers for this?

Thanks a lot,
