The Content

The DETHERM database provides thermophysical property data for about 26,500 pure compounds and 101,300 mixtures . DETHERM contains Literature values, together with bibliographical information, descriptors and abstracts. At the time 5.88 million data sets are stored. The database is updated yearly and grows continually with around 8 % per anno. Convince yourself from the coverage and content of our database using the Online System .

The following properties are stored:

• phase equilibrium data
• vapor pressures, critical data
• thermodynamic properties
• transport properties
• surface tensions
• electrolyte data

 The Internet Access

Using DETHERM ... on the WEB you can access the complete DETHERM database sur your web browser. Use the free of charge service to check if DETHERM contains the data for your problem. DETHERM ... on the WEB has got a multitude of additional features - particulary the automatic export of data to utilize them in a process simulation package (e.g. ASPEN PLUS).

To access the data itself, a registered account is neccessary.

 The Producers

The DETHERM database is produced from the DECHEMA e.V. in cooperation with the FIZ CHEMIE in Berlin and the DDBST GmbH, Oldenburg. DETHERM as a whole consists of a set of property orientated packages. Each package is maintained and produced by external experts. This approach garantees high quality and checked data. Examples for such packages are the Dortmunder Datenbank DDB from the DDBST GmbH, the FIZ-Chemie database INFOTHERM or the electrolyte database ELDAR from the University of Regensburg.

 The Inhouse System

A DETHERM Inhouse Installation consists of SQL database server in combination with the retrieval package DETHERM-ORS.

The user friendly interface enables even unskilled users a rapid and easy access of desired data. The graphical display of data gives an overview on thedistribution of the differnt data sets.

For further processing the data can be exported in various formats (XML, CSV, IK-CAPE PPDX ). Users of MS/Excel can cut & paste the data also directly. Seamless interfaces are existing to a variety of process simulation and data regression packages.

The user's own data can be readily handled with the data maintenance module .

Running in Client-Server-Mode assures that all users of the system use identical data sets. Multiple data sets and the use of differing values from user to user can thus be avoided.
