Please find below list of publications associated to different parts of the DDB and the DDB software package. In addition to the literature sources given here, additional references for experimental data can be found on the different DDB pages. The Dortmund Data Bank (DDB) was started in 1973 with the intention to employ the vast store of vapor-liquid equilibrium (VLE) data from the literature for the development of models for the prediction of VLE. From the beginning, the structure of the DDB has been organized in such a way that it was possible to take advantage of the full potential of electronic computers. With the experience.
The next joint DDBST user and UNIFAC consortium member meeting is planned for September 19th to 20th, 2017.
The first day, Tuesday, will be filled, as usual, with lectures and discussions. We invite our customers and the consortium members to contribute own (short) lectures. The second day will be open for personal appointments and there will be a free course presenting the content of the Dortmund Data Bank and the features of DDBST's software package. further information can be found here.

DDBST has published an Explorer Version of its software and the Dortmund Data Bank. This DDB Explorer Version is a stripped down – but still useful demo version of the DDB and the DDB software package.
The Explorer Version contains data for 30 components and for the mixtures that can be build from these components. DDBST has decided to publish the experimental data from the Explorer Version directly on the Internet.
Data from eight data banks are available:

* approximate number of data sets compared to the complete data bank.
In total, there are data for 815 systems available. Compared to the systems stored in the Dortmund Dabank this is only a very small fraction.
For most binary systems at least a single diagram with the standard representation of the property is available.
