Detherm Database (2025)

: Utilize the DETHERM Online System to filter by CAS numbers, sum formulas, or specific property ranges.

DETHERM is available through several interfaces depending on the user's needs. Organizations like the Chemical Database Service (CDS) in the UK have historically hosted access for academic users, though the primary commercial distribution is handled by DECHEMA.

Coverage for approximately . Information on over 97,000 to 105,000 mixtures . 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.

The database includes thermodynamic and transport properties, such as: : Utilize the DETHERM Online System to filter

Researchers frequently compare their experimental findings—such as high-pressure phase behavior or surface tension measurements—against the DETHERM library to ensure accuracy and consistency.

: Compare different Equation of State (EoS) models—like Antoine vs. Wagner for vapor pressure—to see which better fits the experimental points you retrieved. Coverage for approximately
