DETHERM (R) - a thermophysical property database

The DETHERM(R) database contains thermophysical properties of pure substanc es and mixtures and is one of the worlds largest data collection in this fi eld. DETHERM(R) actually contains 2.85 million data sets for around 100,000 systems (16,000 pure components and 84,000 mixtures). Stored properties ar e: phase equilibria (vapour-liquid, liquid-liquid, gas-liquid, solid-liquid ), azeotropic data, vapour pressures, critical data, caloric properties suc h as heat capacities, enthalpies and entropies, densities, compressibilitie s, transport properties such as viscosity, thermal conductivities and diffu sion coefficients, surface tensions and electrolyte data such as solubility , electrical conductivities, activity coefficients, phase equilibrium data and transport properties. A bibliographic reference, descriptors and an abs tract are always accessible with the numerical data. The article gives an o verview about the contents of the DETHERM(R) database, access options and t he features of the retrieval software package including numerical subroutin es like parameter regression and interfaces to process simulator packages.
