TDE 103b 10.0

TDE 103b is a release of NIST’s ThermoData Engine (TDE), a professional system for acquiring, evaluating, and delivering thermophysical and thermochemical property data for pure compounds and mixtures. Developed by the Thermodynamics Research Center at NIST, TDE combines a curated literature database with automated quality checks and expert evaluation methods to produce recommended property values with documented uncertainties and full source traceability. It covers a wide range of properties—including phase equilibria, densities, heat capacities, enthalpies, vapor pressures, and selected transport properties—and provides tools to correlate data with standard models and to estimate missing values when measurements are unavailable. TDE is used in research and process design to validate data, fit models, and build reliable property packages. The 103b release maintains TDE’s emphasis on data quality and reproducibility, offering an interactive interface for searching, visualizing, and exporting results to support analysis and integration into engineering workflows.

TDE 103b is developed by NIST. The most popular versions of this product among our users are: 4.0, 5.0, 7.0 and 10.0. The name of the program executable file is TDE.exe.
