The pure component properties part of the Dortmund Data Bank contains experimental vapor pressure data sets, sublimation pressures, saturation vapor pressures, and vapor pressures above supercooled water. Besides these equilibrium data the DDB also offers a lot of PvT data of water including a lot of data at supercritical conditions.

Dortmund Data Bank Explorer Version 2020. Introduction What's new? Components in the Explorer Version Download. The DDB Explorer Version 2020 is a demo of the DDB and the DDB software package and is intended only for test purposes and to show the possibilities of the full versions. Based on data for 30 components (see table below) and their.
Since the start of the DDB in 1973, a large number of software tools have been developed to search, retrieve, export, visualize and regress the data. Later these programs were extended to cover further applications like e.g. process synthesis. At the same time, data and parameter communication with other software products was enhanced. Today it is even possible to use the thermodynamic calculation engines of Aspen Plus®, UniSim Design® , Simulis Thermodynamics®or Pro/II® from inside the DDB.
All programs have been integrated under the MS-Windows graphical user interface and can be easily used even without studying the manuals.
The following table compiles most of the major parts. Detailed information can be found on the separate linked pages.

With a view to the synthesis and design of separation processes, fitting and critical examination of model parameters used for process simulation and the development of group contribution methods 1973 a computerized data bank for phase equilibrium data was started by J. Gmehling and U. Onken at the University of Dortmund.
While at the beginning mainly VLE data for non-electrolyte mixtures (Tb > 0 °C) were considered, later on also VLE including compounds with Tb<0°C, LLE, hE, g∞, azeotropic, cPE, SLE, vE, adsorption equilibrium, polymer data, transport properties, ... for non-electrolyte and electrolyte systems as well as pure component properties were stored. The DDB currently (2021-April-08) contains 9.13 million data tuples for approximately 83,000 components from 88,600 references (187,000 evaluated). The data bank can be searched online for free (only data from the open literature are reported).
The Dortmund Data Bank (DDB) now contains nearly all worldwide available phase equilibrium data, excess properties, transport properties and pure component properties even for polymer and electrolyte systems. The status of the Dortmund Data Bank Version 2020 is given below in a diagram.
These data will not be provided by online-services and are not made available to competitors of DDBST GmbH. The only access to these data is via a DDB inhouse license.
The regular yearly update of the DDB can be judged from the figure below. DDB grows by nearly 8% per year in data volume. Nearly all data input is done at DDBST GmbH in Oldenburg by long term employees with many years of experience with support from colleagues in China, Japan, Korea, Estonia, ….
