TRC Thermodynamic Tables
The TRC Thermodynamic Tables - Hydrocarbons and the TRC Thermodynamic Tables - Non-Hydrocarbons are technical resources used extensively by the petrochemical industry. Authors in technical and scientific journals regularly cite the Tables as as reputable source of evaluated thermophysical and thermodynamic data. Evaluated properties that appear in the TRC Thermodynamic Tables are:
Simple Physical Properties
- Boiling point and freezing point
- Refractive index and density at 20 and 25C
- Critical constants: TC, PC, VC and (PV/RT)C
- Temperature, enthalpy, and entropy of: sublimation, vaporization and/or fusion; cryoscopic constants
- Thermodynamic properties of condensed phases: enthalpy, entropy, heat capacity and Gibbs energy function from 0 K to the highest temperature available experimental
- Ideal gas thermodynamic properties: heat capacity, enthalpy, entropy, enthalpy function, Gibbs energy function, enthalpy of formation, and Gibbs energy of formation from 0 to 1500K or 0 to 3000 K
- Densities, surface tension, and viscosity
- Refractive index, as a function of wavelength and temperature
- Vapor pressure as a function of temperature from 5 x 10-7 bar to the critical pressure
- Thermochemical properties at 298.15 K: enthalpy of combustion, enthalpy of formation, Gibbs energy of formation, entropy, and heat capacity
- Equation of state
- Residual enthalpy
- Compressibility factor
- Residual entropy
- Fugacity coefficient
