TDE Experiment Planning: Recommend Measurements (Pure Compound)

Overview and Process Steps

  • Step 1: Select Recommend Measurements (Pure Compound) from the Experiment Planning Menu: Show
  • Step 2: Complete the Compound Selection Form: Show
    • Select a compound
    • TDE analysis begins automatically.
  • Step 3: View Results: Show
    • TDE generates a report in text format.
  • Step 4: Review/Analyze experimental data in TDE (Optional): Go To Compound - Show

Properties Considered:

  • Critical properties
  • Vapor/Sublimation Pressure, Enthalpy of Vaporization
  • Density (sat, liquid)
  • Heat Capacity (crystal and liquid at saturation or near 101 kPa)
  • Speed of Sound, Viscosity, Thermal Conductivity (liquid at saturation or near 101 kPa), and Surface Tension

Analysis is based on:

  • Availability of experimental data
  • Availability of predicted data
  • Inconsistency in experimental data
  • Gaps in experimental temperature-pressure space
  • Possible property derivation from other properties
  • Experimental Uncertainties

Possible findings returned by TDE for each property:

  • No experimental data or prediction; new data would be beneficial
  • No experimental data, but prediction available; new data needed for prediction validation
  • No direct experimental data, but can be derived (e.g. enthalpy of vaporization from vapor pressure); data needed for validation
  • Experimental data, but there are large gaps; data in some ranges are needed
  • Extensive experimental data are available
  • In addition, property measurements are suggested to aid development of a high-precision Helmholtz equation of state
