Joule-Thompson Coefficient Data for high pressures and temperatures

[Wisegriffin]

Having checked Perry's Handbook and a few other sources, I have yet been able to find physical data for Joule-Thompson Coefficients in temperatures ranging from 200-340 degrees C with pressures around 5000, 10000, and 20000 PSI. Would anyone checking this forum have a resource or base paper to find some information on this topic? Specific gases would include N2, Ar, CO2 which are pretty standard. Any help you could provide would be greatly appreciated.

Check with NIST. They have a program called REFPROP that can do it.
