A Simple Computer Tool for Simultaneously Estimating Critical, Transport, Physicochemical, and Phase Change Properties of Ionic Liquids

A simple computer tool based on MS
Excel for estimating several
physical, transport, and thermodynamic properties is presented. The
properties included in the software are critical properties (Tc, Pc, Vc, and Zc), normal boiling
temperature, acentric factor, density, heat capacity, thermal conductivity,
viscosity, surface tension, speed of sound, melting temperature, and
heat of melting. Different types of models previously proposed by
the authors are used and the limitations of each model are clearly
stated. These models include group contributions, semiempirical correlations,
equations of state, and the geometric similitude equation of state
concept. The calculations provided by the software do not aim to replace
experimental data but help in obtaining a good estimate before going
to the lab to experimentally measure a given property. The software
is available free of charge and can be modified for particular applications.
