DETHERM

Another numeric database including bibliographic information is DETHERM. 

This database provides thermophysical property data (phase equilibrium data, critical data, transport properties, surface tensions, electrolyte data) for about 21 000 pure compounds and 101 000 mixtures. DETHERM, with its 4.2 million data sets, is produced by Dechema, FIZ Chcmic (Berlin, Germany) and DDBST GmhH (Oldenburg. Germany). Definitions of the more than SOO properties available in the database can be found in NUMERIGUIDE (sec Section 5.18).

Typical numeric databases are Beilstein, Speclnfo, DETHERM, and the Cambridge Structural Database.

More information abont the DDB, inclnding a list of distributors, may be found at their Web site [13]. One notable feature is a free lookup program that allows one to search the database and see whether or not the DDB contains data for a particnlar system. Much of the data in the DDB is also available through the DETHERM database mentioned in Section 1.9.4.

Compilations of data can be found, e.g., in the classical papers by Pitzer and co-workers [1,6,7]. A very useful tool is provided by the Joint Expert Speciation System (JESS), a joint project of two groups in Australia and South Africa [8, 9]. Also interesting is the data bank from CERE of the Technical University of Denmark for electrolyte solutions [10] and the ELDAR data bank integrated in the Dechema s DETHERM data bank [11] containing values from which activity coefficients can be calculated. 

DETHERM/ELDAR Database The Electrolyte Database Regensburg ELDAR [15] is a numerical property database for electrolytes and electrolyte solutions from the Institute of Physical and Theoretical Chemistry of the University of Regensburg. It started in 1976 and contains data on pure substances and aqueous as well as organic solutimis. The database was designed as a literamre reference, numerical data, and also model database for fundamental electrochemical research, applied research, and also the design of production processes. 

ELDAR is distributed as part of DECHEMA s numerical database for theimophysical property data DETHERM [16, 17], To access ELDAR, one can therefore use several options. 

The two coUectiOTis together currently contain around 11,000 data sets. Access to these collections is possible either (Hitine using the DETHERM. .. on the Web service or in-house using special software from DDBST or DECHEMA.

Check if BIPs for all the binary pairs in the system are available in the simulator data bank (the most common source is DETHERM thermophysical database [14]). For the three most common models (Wilson nonrandom two liquid [NRTL] and UNIversal QUAsiChemical [UNIQUAC]), the values of BIPs are different, and they are not correlated from one model to another.
