The DIPPR database is an extensive compilation of rigorously evaluated pure component physical property data. The DIPPR version 1.0 database is based on the Microsoft Access database format. This format can be read in by a number of third party software programs. Cranium and Synapse can also import physical property data and estimates from DIPPR version 1.0 database format.
Both Cranium and Synapse have import capabilities that enable them to add large quantities of values to knowledge bases. These values are often distributed across many chemicals, techniques, and references. Thus the importation of values cannot be undone. We strongly recommend that you: 1) first import values into a new, expendable knowledge base; 2) verify that the values were imported correctly; 3) backup the destination knowledge base (see documenation on Copy Document for details); 4) only then import values into your permanent, destination knowledge base.
Cranium and Synapse create a DIPPR v01 formatted database containing eleven tables. Note that information in some of the columns are applicable only to DIPPR specific activities, e.g., review dates, and thus values for such columns are not imported. Examples of the tables generated by Cranium and Synapse are shown here (note that only the first 250 records of each file are shown):
|Browse button for entering the name of the export file.
|The entity type being displayed. The entity types are Chemical, Reference and Technique.
|List of entities selected that can be imported.
|The properties to be imported. Often you use the All Props button to select all properties for importing.
|The datum status values to be exported. Often you use the All Status button to select all status values for importing.
|Import Options: provides several options for how imported values will be added to the current knowledge bases. Selecting an option displays the option's documents in the accompanying text control.
|Export: press this button to begin the import process
The following example database was contains seven chemicals (acetic acid, cyclohexanol, ethanol, ethyl acetate, n-hexane, toluene and vinyl chloride) and several estimation technique parameter sets. You can use this example database to experiment with Cranium's and Synapse's import capabilities. (See the warning at the top of this page.)
