Free Data from the DDB

VLE of Chloroform and MethanolDDBST has published a free Explorer Version of its software and the Dortmund Data Bank. This DDB Explorer Version is a stripped down – but still useful and completely free – basic 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:

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.
