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. As such, Cranium and Synapse can export physical property data and estimates into the DIPPR version 1.0 database format.

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 generated. Examples of the tables generated by Cranium and Synapse are shown here (note that only the first 250 records of each file are shown):

1. Open a Knowledge Base using either Cranium or Synapse.
2. Click on the File menu and select the Export Values command.
3. The application will activate the KB Export Dialog.
4. Select 'DIPPR (V01) Format' from the Output File Format list and press the Export button. The Create a DIPPR v01 Database dialog is activated.

   1	Browse button for entering the name of the export file.
   2	The entity type being displayed. The entity types are Chemical, Reference and Technique.
   3	List of entities selected to be exported.
   4	Options for exporting internal entities: Internal chemicals: option to export chemicals that were not explicitly selected but are listed in estimation technique parameter lists. Internal references: option to export references that were not explicitly selected but are cited by exported chemicals and techniques.
   5	The properties to be exported. Often you use the All Props button to select all properties for exporting.
   6	The datum status values to be exported. Often you use the All Status button to select all status values for exporting.
   7	Buttons for: All Entities: selects all entities of the currently displayed entity type All Props: selects all properties of the currently displayed entity type All Status: selects all status values of the currently displayed entity type Select Entity: use the Find Entity dialog to find an entity by its name or other attributes Clear Entities: deselects all entities of the currently displayed entity type Clear Props: deselects all properties of the currently displayed entity type Clear Status: deselects all status values of the currently displayed entity type Bookmark: use a bookmark to select entities
   8	Export button

5. Press the Browse button to select the database file into which the exported values will be written.
6. Click on the Entity Type combobox and select the Chemical entity type.
7. Select one or more chemicals from the Entities list. Use the Select Entity or Bookmark buttons to facilitate your selection. You can also press the All Entities button to select all displayed entities for export.
8. Select one or more properties from the Properties list. You can press the All Props button to select all displayed properties for export.
9. Select one or more status values from the Status list. You can press the All Status button to select all displayed status values for export.
10. Repeat the selection steps for the Reference and Technique entity types. Note: using the Internal References option is often very useful - the application will automatically select those references cited by the exported chemicals and techniques.
11. Finally press the dialog's Export button. Cranium or Synapse will compile physical property data, physical property estimates and estimation techniques parameters and write these values into the named database file.

The following example database was generated by exporting seven chemicals (acetic acid, cyclohexanol, ethanol, ethyl acetate, n-hexane, toluene and vinyl chloride) and several estimation technique parameter sets. The export options were set to export all internal references but only export explicitly selected chemicals.
