However, for older, more “traditional” data compilations, the transition to electronic data delivery poses significant challenges. One of the best examples of this effective combination is the NIST Chemistry WebBook that started in the mid-1990s and has proven to be very successful. The second component is the efficient means of information delivery, and, in today’s world, it is indisputably the Internet. In terms of current technology, this solution usually comes in the form of an electronic database. First, an efficient information storage and retrieval mechanism must be established. To provide this availability, two major components have to be in place. On-demand availability of thermophysical and thermochemical property data has become essential to sustain rapid technological development in the modern world. WTT are distributed through the NIST Standard Reference Data Program. Various search options and data plotting capabilities are provided via the Web interface. The tabulated information includes critical properties, vapor pressures and boiling temperatures, phase transition properties, volumetric properties, heat capacities and derived properties, transport properties, reaction state-change properties, as well as index of refraction, surface tension, and speed of sound.
Presently, WTT contains data for 7838 compounds and over 950,000 evaluated data points.
To facilitate more flexible, convenient, and up-to-date access to the data, here, we present the release of the on-line version of the TRC tables, Web Thermo Tables (WTT). Over their long history, the TRC Tables have always been valued as a reputable source of evaluated thermophysical and thermodynamic data.
For over 65 years, the Thermodynamics Research Center (TRC) has been publishing tables of critically evaluated data covering physical and thermodynamic properties of pure compounds, TRC Tables-Hydrocarbons and TRC Tables-Non-Hydrocarbons. It has long been understood that availability of thermophysical and thermochemical property data is vital to scientific research and industrial design.
