PhysProps is an advanced, pure component, thermophysical property data base and property estimating application for Windows (tm) based computer systems. The database is composed of over 6,500 chemical specie names and their synonyms (both organic and inorganic compounds). The software was designed with the user in mind and offers simplicity of use, a logical interface, and flexible data presentation.

Searching through the database is extremely simple. Simply type in the first few letters of the compound's common or IUPAC name (International Union of Pure and Applied Chemistry), and PhysProps "search as you type" feature quickly finds the compound of interest. The data base supports 16 intrinsic properties such as Tc, Pc, Vc, Tnbp, Tmp, dHf, dGf, dSf, dHfus, dHc, and acentric factor and 12 temperature dependent properties such as vapor pressure, densities, viscosities, thermal conductivities, and heat capacities. The temperature dependent properties can be viewed in a tabular or graphical format.

In addition, if your particular compound is not in the database, properties can be estimated from an advanced and extremely powerful estimation module within PhysProps. The estimation routines includes the methods of Joback/Lydersen, Lee-Kesler, Pitzer, Letsou-Stiel, Rowlinson-Bondi, and Misic-Thodos. This set of estimation routines is ideal for engineers and chemists who need to obtain estimates of properties for complex compounds that possibly have never been synthesized before. And as with the data base, estimated properties can be viewed in a tabular or graphical format.

Confusion and mistakes caused by mixed or inconsistent units of measurements are eliminated with PhysProps. Users may select data to be displayed from any one of three standard units sets (American Engineering, metric, or SI) or set any unit individually. PhysProps will also remember the selected unit set for future sessions.

Also included within PhysProps is a graphically based Periodic Table of the elements. At the press of a button, critical information on any element may be instantly obtained. Access to a scientific calculator is also quickly available from within the application.
