The Dortmund Data Bank[1] (short DDB) is a factual data bank for thermodynamic and thermophysical data. Its main usage is the data supply for process simulation where experimental data are the basis for the design, analysis, synthesis, and optimization of chemical processes. The DDB is used for fitting parameters for thermodynamic models like NRTL or UNIQUAC and for many different equations describing pure component properties, e.g., the Antoine equation for vapor pressures. The DDB is also used for the development and revision of predictive methods like UNIFAC and PSRK.
Contents[edit]
Mixture properties[edit]
- Phase equilibria data (vapor–liquid, liquid–liquid, solid–liquid), data on azeotropy and zeotropy
- Gas solubilities
- Activity coefficients at infinite dilution
- Heat capacities and excess heat capacities
- Volumes, densities, and excess volumes (volume effect of mixing)
- Salt solubilities
The mixture data banks contain currently (April 2007) approx. 308,000 data sets with 2,157,000 data points for 10750 components building 84870 different binary, ternary, and higher systems/combinations.
Pure component properties[edit]
- Saturated vapor pressures
- Saturated densities
- Critical data (Tc, Pc, Vc)
- Heats of fusion, sublimation and vaporization
- Heats of formation and combustion
- Heats and temperatures of transitions for solids
- P-v-T data including virial coefficients
- Energy functions
- Enthalpies and entropies
The pure component properties data bank contains currently (April 2007) approx. 157,000 data sets with 1,080,000 data points for 16700 different components.

Data sources[edit]
The DDB is a collection of experimental data published by the original authors. All data are referenced and a quite large literature data bank is part of the DDB, currently containing more than 92,000 articles, books, private communications, deposited documents from Russia (VINITI), the Ukraine (Ukrniiti) and other former USSR states, company reports (mainly from former GDR companies), theses, patents, and conference contributions.
Secondary sources like data collections are normally neglected and only used as a literature source. Derived data are also not collected with the main exception of the azeotropic data bank which is built partly from evaluated vapor–liquid equilibrium data.
History[edit]
The Dortmund Data Bank was founded in the 1970s at the University of Dortmund in Germany. The original reason for starting a vapor–liquid phase equilibria data collection was the development[2] of the group contribution methodUNIFAC which allows to estimate vapor pressures of mixtures.
The DDB has since been extended to many other properties and has increased dramatically in size also because of intensive (German) government aid. The funding has ended and the further development and maintenance is performed by DDBST GmbH, a company founded by members of the industrial chemistry chair of the Carl von OssietzkyUniversity of Oldenburg, Germany.
Additional contributors are the DECHEMA, the FIZ CHEMIE (Berlin), the Technical University in Tallinn, and others.
Availability[edit]
The Dortmund Data Bank is distributed by DDBST GmbH as in-house software. Many parts of the Dortmund Data Bank are also distributed as part of the DETHERM data bank which is also available online.

The major product of DDBST is the Dortmund Data Bank (DDB) for thermophysical properties of pure component and mixtures, which was started in 1973 and is continuously updated and extended. DDB grows by approximately 8% p. a.
The powerful DDB software package features a wide variety of functionalities to optimally employ the vast amount of knowledge stored in the DDB and a variety of modern property estimation and regression techniques. Special data mining tools for process synthesis potentially lead to new solutions for engineering and environmental problems.
DDBST offers consulting services ranging from data regression or estimation to the generation of complex property packages or development and up-front evaluation of process alternatives.
A variety of very successful training courses are available covering the thermodynamic and engineering background and to enable customers to efficiently use the data bank and software tools.
DDBST offers a download with strongly restricted functionality in form of a Explorer Version. Data can also be searched online via this website.
Our Educational Version is used at many Universities worldwide to let students become familiar with a wide variety of thermophysical property issues.
Dortmund Data Bank
Today the DDB represents the largest computerized data bank for thermodynamic pure component and mixture properties (info and detailed status). Besides data from the open literature, also a large number of data from private communications or company data can be found in the DDB.
