Finding Thermodynamic and Physical Property Data

Where to Start

CRC handbook of chemistry and physics. organics inorganics U.T. restricted recommended resource
print 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 organics critically evaluated data U.T. restricted recommended resource
The Design Institute for Physical Property Data (DIPPR) Project 801 database consists of experimental data and correlations of temperature-dependent properties for over 1,800 pure chemicals, mostly organic, with a couple hundred inorganic as well. 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 organics inorganics
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. Data are sourced from public web sites and non-copyrighted publications, and reviewed by Knovel staff.

NIST Chemistry WebBook organics inorganics critically evaluated data recommended resource
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 organics critically evaluated data U.T. restricted recommended resource
The TRC Thermodynamic Tables database (WTT) offers a collection of critically evaluated thermodynamic property data for over 23,000 pure organic compounds. Searchable by name/segment, formula, and molecular weight. Recommended values can be plotted (Adobe Flash plugin required).

Reaxys organics inorganics U.T. restricted recommended resource
A vast amount of factual data for chemical compounds derived from the historical Beilstein and Gmelin handbooks, and more recently gathered from the journal and patent literature.

SciFinder - Registry organics inorganics polymers U.T. restricted recommended resource
CAS has added an array of calculated and experimental property data to selected substance records in the Registry database. Many types of experimental properties have also been added under a separate tab, with corresponding references to the source literature for each. Calculated properties are primarily of pharmaceutical interest. Start in the Explore Substances tab, search for a compound by structure, name/synonym, molecular formula, or CAS Registry number, and then click on the Substance Detail link. You can also search for substances directly using property values, or enter values to refine an existing substance answer set.

Thermophysical Properties of Matter TPMD inorganics critically evaluated data U.T. restricted
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 is a finding aid for more than 300 specialized property handbooks and compilations, searchable by type of compound and name of property. Most compilations indexed in ThermoDex are in printed form, and must be consulted in the library.
