TDE-SOURCE Archive of Experimental Property Data
The TDE-SOURCE archive of experimental data is a subset of the TRC SOURCE
archive. The TRC SOURCE
[9, 10]
archive was designed and built as an extensive
relational data archival system for experimental thermophysical and
thermochemical properties reported in the world's scientific literature. The
TRC SOURCE archive now includes more than 4 million numerical property values with
uncertainties estimated at TRC for more than 20,000 pure compounds, 40,000 binary
and ternary mixtures, and 6000 reaction systems. Its structure is based
principally on the Gibbs phase rule and serves as a comprehensive
data storage facility of experimental
property data for implementation of the dynamic data evaluation concept. At
present, the rate of collection of numerical property values is near 0.4 million
per year. It is estimated that TRC SOURCE contains approximately 80% of the
available
experimental thermodynamic data for organic molecular compounds.
