Finding Thermodynamic and Physical Property Data
Where to Start
- CRC handbook of chemistry and physics.
Published annually by CRC Press. Recent editions on the Handbook Table. - Almost every data search on a chemical property should begin in the CRC. In the printed handbook, consult the index under the property in question.
- DIPPR Physical and Thermodynamic Properties
- The Design Institute for Physical Property Data (DIPPR) Project 801 database consists of experimental data and correlations of temperature-dependent properties for over 1,900 pure organic chemicals. Collected data have been evaluated, correlated, and checked for thermodynamic consistency. From this site, you can view data sets, DIPPR-approved property constants, and regressed correlation coefficients for temperature-dependent properties, as well as calculate temperature-dependent properties in any set of units. Searchable by chemical name, CAS registry number, empirical and structural formulas, and numeric property ranges.
- Knovel Critical Tables
- This interactive site contains tables of physical, solvent, and thermodynamic properties. The physical property tables include over 21,000 inorganic and organic compounds. Some tables make use of an interactive Equation Plotter to plot thermodynamic properties as a function of temperature.
- NIST Chemistry WebBook
- A free web site providing reliable thermophysical and spectral data for a few thousand important compounds. Much of the data is derived from prior NIST/NBS publications. Searchable by name, CAS registry number, formula, molecular weight, etc.
- NIST-TRC Web Thermo Tables
- The TRC Thermodynamic Tables database offers a collection of critically evaluated thermodynamic property data primarily for pure organic compounds. As of January 2008 it contains information on 7765 compounds with 890,684 evaluated data points. Searchable by name/segment, formula, and molecular weight. Interactive plotting is performed with Ptplot Java Applet.
- Reaxys
- The Beilstein and Gmelin databases contain a vast amount of factual data for chemical compounds gathered from the journal literature. Search for a compound by structure, name, or CAS Registry number, then see the Details table for a list of data fields available for that substance. Beilstein is also available through 2010 via the Crossfire system.
- Thermophysical Properties of Matter TPMD
- TPMD covers 60 properties of nearly 5000 inorganic, metal, and composite materials and alloys, totaling nearly 50,000 data curves and 21,000 data sets. You can browse or search by material or property. (CINDAS)
- ThermoDex
- ThermoDex is a finding aid to identifying around 300 specialized property handbooks and compilations in the library, searchable by type of compound and name of property. Most compilations indexed in ThermoDex exist only in printed form, and must be consulted in the library. ThermoDex is a meta-index and does not contain the actual data.
