The literature prior to November, 1965 was searched for cryogenic properties of the following pure refrigerants and mixtures helium-4 para-, ortho-, and normal hydrogen deuterium hydrogen deuteride neon nitrogen argon oxygen methane krypton refrigerant-13 ethene refrigerant-23 refrigerant-14 carbon dioxide helium-3 - helium-4 hydrogen-neon nitrogen-argon nitrogen-methane methane-ethane argon-methane refrigerant-14 - refrigerant-23 and refrigerant-13 - refrigerant-23. The properties of interest were PVT including compressibility, density, and virial coefficients equation of state phase equilibrium data enthalpy, entropy heat capacity latent heat Joule-Thomson coefficient effect thermal pressure coefficients of compression and expansion thermal conductivity viscosity velocity of sound and surface tension. Phase equilibria data were sought for the following binary mixtures helium-hydrogen helium-neon hydrogen-nitrogen hydrogen-argon neon-nitrogen neon-argon neon-oxygen helium-carbon monoxide hydrogen-carbon monoxide neon-carbon monoxide carbon dioxide in each of nitrogen, argon, oxygen, methane, and ethane and hydrocarbons in oxygen. A survey was made of the research activities of all other laboratories known to be measuring the thermodynamic and thermophysical properties of cryogenic materials. Author
