SUMMARY

The discussion centers on the Joule-Thomson effect and the need for references regarding inversion temperatures for specific molecules. Key resources mentioned include the International Critical Tables, JANAF Tables, and notable texts by Hirschfelder, Curtis, and Byrd, as well as Lewis & Randall, Klotz, and Rowlinson. Software tools such as TRAPP, SuperTRAPP (NIST), and ASPEN are highlighted for their relevance in this area. The conversation notes that inversion temperatures have been established primarily for lighter gases like hydrogen and helium, with potential data available for neon and argon.

PREREQUISITES
  • Understanding of the Joule-Thomson effect
  • Familiarity with inversion temperatures in thermodynamics
  • Knowledge of relevant engineering handbooks in refrigeration and cryogenics
  • Experience with software tools like TRAPP and ASPEN
NEXT STEPS
  • Research the International Critical Tables for inversion temperature data
  • Explore the JANAF Tables for thermodynamic properties of molecules

Does anybody have any decent references for this, or a table with inversion temperatures for specific molecules?

International Critical Tables, JANAF Tables; you might browse Hirschfelder, Curtis, and Byrd, Lewis & Randall, Klotz, or Rowlinson; software packages in the public domain --- TRAPP, SuperTRAPP (NIST), and commercial, ASPEN (probably under a different name --- it gets bought and sold on about 6mo. cycle --- is big bucks expensive).

Inversion temps? I ain't sure anyone's found such for anything heavier than hydrogen and helium (gotta suspect such has been pinned down for neon, and maybe argon). HC&B should give you hints on the calculations for predicting such.

Other sources to try are refrigeration/HVAC and cryogenic handbooks in the engineering sections of your nearest "full service" library.
