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):
|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 to be exported.
Options for exporting internal entities:
|The properties to be exported. Often you use the All Props button to select all properties for exporting.
|The datum status values to be exported. Often you use the All Status button to select all status values for exporting.
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.
