Detherm Database

: Use the DECHEMA Data Preparation Package (DPP) to regress model parameters (e.g., NRTL, Wilson, or UNIQUAC) directly from the raw DETHERM data.

| Database | Focus | Access | |----------|-------|--------| | | Broad, evaluated experimental data | Commercial | | NIST TDE | Pure & mixture properties, with prediction tools | Free limited / commercial | | DDBST | Phase equilibria (Dortmund Data Bank) | Commercial | | ThermoML | XML-based exchange format | Open metadata | detherm database

Users can typically search the database via the web to view "hit sets" (the number of available data points for a specific search) for free, though downloading the full numerical data often requires a subscription or a "pay-per-view" fee. For high-frequency industrial users, "Inhouse" versions are available that integrate directly with existing corporate software ecosystems.
